UK personal finance flowchart

The standard UK answer to “I have some spare money, what should I do with it?” is an eight-step order of operations. It normally arrives as a picture. This version runs it against your own numbers, tells you which step you are standing on, and says what your next spare £100 should actually do.

It is current for the 2026/27 tax year, and it does something a picture cannot: it names the parts of the answer that are already scheduled to change, with the dates. The cash ISA limit is cut in April 2027 and the Lifetime ISA is replaced in April 2028, which quietly dates most of the copies of this chart in circulation.

Credit where it is due

The order of operations below is community knowledge, maintained by the volunteers behind the UKPersonalFinance wiki flowchart, which is the canonical version and worth reading in full. This page is an independent implementation of that widely published order: our own wording, our own logic, no part of their chart or their text reproduced. The step numbering and the ordering here follow their chart exactly, checked against version 3.0.10 (dated 22/12/2025) on 24/08/2026.

The eight steps, in order

Work down the list. You only move on once the step above is genuinely handled, because each one protects the steps below it. Open any step to see what it involves.

  1. 1Budget, cover the essentials, clear expensive debtHousing, council tax, food, energy, insurance, minimum payments on everything, and any debt above 10% APR attacked highest rate first.
    • Write down every essential cost: rent or mortgage, council tax, energy, water, food, and whatever it costs to get to work.
    • Check what you are entitled to. Benefits and council tax support go unclaimed every year by people who assumed they would not qualify.
    • Insure the things that would sink you: car cover (legally required), home cover, life cover if anyone depends on your income, and income protection.
    • Pay at least the minimum on every debt, always. Missing a payment costs more than the interest does.
    • If you are relying on credit or an overdraft to cover essentials, stop here and get free debt advice. That is not a failure, it is the correct move.
    • Then clear anything above 10% APR, highest rate first, before building savings. Above that rate, clearing the debt beats any return you can count on elsewhere, and it is guaranteed. Refinance where you can: a balance transfer or a lower rate loan cuts the cost without needing more money.
    • Cheaper debt waits. It gets its minimum payment now and a proper look at step 4.
  2. 2Build a starter emergency fundOne to three months of outgoings, in cash you can reach the same day.
    • The job of this money is not growth. It is to stop the next boiler, tyre or vet bill turning into a credit card balance.
    • Instant access, separate from the current account so it does not get spent by accident.
    • One month is enough to move on from. Three is more comfortable if your income is lumpy.
  3. 3Take the full employer pension matchContribute enough to collect every pound your employer will match.
    • A match is money added on top of your own contribution. Nothing else on this list adds that much for so little risk.
    • Check the scheme rules for the maximum percentage your employer will match, then contribute at least that much.
    • Tax relief comes on top, so the cost to your take-home pay is less than the amount going in.
  4. 4Put the remaining debts on a scheduleAnything left that is not the mortgage or a student loan gets a written repayment plan, weighed against what savings pay.
    • By this point nothing you owe should be above 10% APR, because step 1 cleared it. What is left is the cheaper kind: the car loan, the 0% card, the sofa on finance.
    • Write down when each one clears at its current payment, then compare each rate with what an easy-access savings account pays. A debt charging less than savings earn is not urgent. One charging more is worth overpaying once the emergency fund is under way.
    • Keep paying at least the minimum on all of them, always.
    • The mortgage and any student loan sit outside this step on purpose. Whether overpaying those beats saving or investing is a genuine question with its own arithmetic, and the order comes back to it right at the end, once your short-term goals are on track.
  5. 5Finish the emergency fundThree to twelve months of outgoings, depending on how stable your income is.
    • Three months suits a secure salary with another earner in the household.
    • Six to twelve suits self-employment, commission, a single income, or a job that would be slow to replace.
    • Still cash, still instant access. This is the money that buys you the time to make good decisions instead of desperate ones.
  6. 6Define your goals with amounts and datesA goal without a number and a date cannot be planned for, only hoped for.
    • The defensive work is done, and this is also the point where the order tells you to look at the budget again and loosen the discretionary spending if you want to. Then give what is left a job.
    • Name each one: deposit, wedding, car, career break, retirement.
    • Give every goal an amount and a target date. The date is what picks the account, and the amount is what tells you the monthly figure.
    • The date sorts the goals into the next two steps. Under five years is one kind of money. Over five years is a completely different kind.
  7. 7Short-term goals, under five yearsCash Lifetime ISA for a first home, savings accounts, Premium Bonds.
    • Under five years the job of the money is to still be there on the day you need it, not to grow.
    • A cash Lifetime ISA adds a 25% government bonus on up to £4,000 a year, worth up to £1,000, for a first home up to £450,000. You have to be 18 to 39 to open one, and taking the money out for anything else before 60 carries a withdrawal charge. (2026/27 rules.)
    • This one has a shelf life. The Lifetime ISA is due to be replaced by a First Time Buyer ISA from around April 2028, and the cash ISA limit is being cut for under-65s from 6 April 2027. Existing Lifetime ISA holders keep contributing and keep the bonus. See what changes next, further down this page.
    • Otherwise a plain savings account, a fixed term account if the date is certain, or Premium Bonds if you would rather have the option of a win than a predictable rate.
    • Investing money you need in three years is how people end up selling at the worst possible moment.
  8. 8Long-term goals, over five yearsStocks and Shares ISA, Lifetime ISA, workplace pension, SIPP, then a General Investment Account.
    • Over five years the risk flips. Cash is the thing that quietly loses, and the Stocks and Shares ISA is the usual home for money you will not touch. The overall ISA allowance is £20,000 a year in 2026/27, and from 6 April 2027 more of it has to sit outside cash if you are under 65.
    • The order splits this step by when you will want the money relative to your pension access age, which it puts at roughly 58. Money needed before then goes to ISAs or a General Investment Account, because a pension will not give it back in time. Money for after goes to the pension first, because nothing else matches the tax treatment. The minimum pension age rises from 55 to 57 on 6 April 2028, and the chart plans around 58 to leave room for further rises.
    • If you pay 40% or more, a SIPP or extra workplace contributions get relief at your marginal rate, inside a £60,000 annual allowance in 2026/27.
    • A Stocks and Shares Lifetime ISA carries the same 25% bonus and the same rules as the cash version, and the same April 2028 replacement, which suits a first home that is genuinely years away.
    • Inside whichever account wins, what the order actually points at is long-term investing in low-cost index funds. Picking individual shares is not on the chart.
    • A General Investment Account comes last, once the tax-free allowances are genuinely used up. Dividend tax rose by 2 percentage points in April 2026, so the gap between inside and outside an ISA got wider, not narrower.
    • One more thing before the money is invested: if the mortgage or a student loan is still there, this is where the order has you weigh an overpayment against your goals. Not before.

Which step are you on?

Seven quick questions, all of them skippable. Answer what you know and you still get a useful answer, with the gaps named rather than guessed at.

Question 1 of 7

Relates to step 1

What do your essentials cost each month?

£

Rent or mortgage, council tax, energy, water, food, insurance, and getting to work. Not holidays or takeaways.

Do those get paid every month without borrowing?

Nothing you type here is sent anywhere or stored. It stays in your browser, and refreshing the page clears it. Debts at or above 10% APR are the ones the order treats as urgent.

What changes next, and when

The order of the eight steps is stable. The products at the bottom of it are not. These are the dated changes already announced, which is exactly what a static picture of this flowchart cannot tell you.

  1. 6 April 2027Announced

    The cash ISA limit is cut for under-65s

    • The amount you can put in a cash ISA falls from £20,000 to £12,000 a year if you are under 65.
    • The overall £20,000 ISA allowance is unchanged. The remaining £8,000 can still be used, but only in a Stocks and Shares ISA, an Innovative Finance ISA or a Lifetime ISA.
    • From the tax year in which you turn 65, the full £20,000 cash limit is kept.
    • Anti-circumvention rules land at the same time: a flat 22% charge on interest paid on cash held inside a non-cash ISA, a bar on non-cash ISA portfolios being made up entirely of cash-like assets (money market funds are the defined cash-like asset), and no transfers from a non-cash ISA into a cash ISA. The transfer bar does not apply to those aged 65 and over.

  2. Around April 2028Detail not final

    The Lifetime ISA is replaced by a First Time Buyer ISA

    • The Lifetime ISA is being scrapped and replaced with a product aimed only at buying a first home. The retirement purpose goes.
    • It was consulted on in early 2026 with further detail in June 2026, so the fine print is not final. It is expected to be available as cash or Stocks and Shares, to drop the 25% withdrawal penalty, and to pay the bonus as a lump sum at purchase.
    • If you already hold a Lifetime ISA you can keep paying into it indefinitely and keep the 25% bonus. Existing Lifetime ISAs cannot be transferred into the new product.
    • This is why step 7 below flags a shelf life on the cash Lifetime ISA rather than presenting it as a permanent fixture.
  3. Now, until April 2031Announced

    Income tax thresholds stay frozen

    • Frozen thresholds mean pay rises drag more people into higher bands over time, which quietly makes pension contributions and ISAs more valuable, not less.
  4. 6 April 2029Announced

    Pension salary sacrifice gets a National Insurance cap

    • The National Insurance exemption on salary-sacrificed pension contributions is capped at £2,000 a year. Anything above that creates a National Insurance liability at your marginal rate.
    • Salary sacrifice still works and the employer match in step 3 is unaffected. The extra saving above £2,000 a year is what shrinks.
  5. No changeAnnounced

    The High Income Child Benefit Charge stays as it is

    • It remains £60,000 to £80,000, and it stays based on individual income rather than household income. The reform to a household-income test is not going ahead.
    • Worth saying out loud because plenty of coverage suggested otherwise.

Why the order matters more than the products

Almost every argument about money in the UK is really an argument about sequence. Cash ISA or Stocks and Shares ISA. Overpay the mortgage or top up the pension. Clear the card or build the buffer. Taken one at a time, each of those has a dozen defensible answers. Put in order, most of them answer themselves.

The order works because each step protects the ones below it. Expensive debt is cleared first, inside step 1, before a penny of savings gets built, because a balance compounding at 25% undoes saving faster than saving can outrun it, and clearing it is the one guaranteed return on the list. The employer pension match comes next, once a small buffer exists, because a match is the only place on the list where money appears from somewhere other than your own income. Investing comes last, not because it is unimportant, but because it is the step most likely to go wrong when the ones above it are missing.

How this page decides which step you are on

It walks the eight steps in order and stops at the first one that is not clearly handled. That is the step you are on. Everything above it is confirmed as done, and everything at or below it is listed as outstanding with the numbers filled in where you gave us enough to fill them.

The tests are deliberately blunt, because the order is meant to be usable rather than precise. A starter emergency fund means at least one month of essential outgoings in cash. Expensive debt means anything at or above 10% APR, attacked highest rate first. A full emergency fund means whatever number of months between three and twelve you told us you want. Goals count once they have both an amount and a date, because the date is what sorts them into cash or investments.

Skipped questions are treated as unknown rather than as passes. If you skip the question a step turns on, the page puts you at that step and says so, rather than waving you past it. That is usually the right answer anyway: a step you cannot confirm is a step worth going and checking.

Where the flowchart tends to trip people up

Three places, mostly. The first is expensive debt sitting inside step 1, before even the starter emergency fund. The widely shared American version of this chart builds a small buffer before touching the debt, the two get mixed up online constantly, and the UK chart is blunt about it: a balance charging over 10% is already an emergency. The second is the emergency fund being split into two steps, which is deliberate: a small buffer early, then the rest later, so the pension match and the debt schedule are not waiting behind a year of cash-building.

The third is the five-year line between short-term and long-term. It is not arbitrary. It is roughly how long a bad run in the markets can last, and money you have to sell on a fixed date is money you might have to sell at the bottom. A house deposit you need in three years belongs in cash, however tempting the alternative looks in a good year. If you are weighing that trade-off on a mortgage rather than a deposit, overpay or invest goes into it properly.

If the essentials are the problem

Step 1 is not a formality. If your income does not cover the essentials, or it only covers them with a credit card or an overdraft filling the gap, nothing further down the list will help and free debt advice will. It is confidential, it is impartial, and it is not a last resort.

Common questions

›What is the UK personal finance flowchart?

It is the order of operations UK money communities point people to when they ask what to do with spare money. It runs from covering the essentials and clearing expensive debt, through a starter emergency fund and the employer pension match, to a full emergency fund, written goals, and finally short-term and long-term investing. The canonical version is maintained on the UKPersonalFinance wiki. This page is an independent interactive implementation of that widely published order, so you can run it against your own numbers instead of reading a static image.

›What order should I pay off debt, save and invest in?

Essentials first: bills paid, minimum payments on every debt, and free debt advice if credit is filling the gap. Any debt above roughly 10% APR is cleared in the same step, highest rate first, before savings get built. Then a starter buffer of about one month of outgoings, then enough pension contribution to collect the full employer match, then a repayment schedule for whatever cheaper debt remains, then the emergency fund topped up to three to twelve months, then goals written down with amounts and dates, then short-term money in cash and long-term money invested. Overpaying the mortgage or a student loan is weighed right at the end, against your goals, not near the start.

›How big should my emergency fund be?

The starter target is one to three months of outgoings, built once the essentials are covered and anything above 10% APR is gone. The full target is three to twelve months, depending on how quickly you could replace your income, and it waits until after the pension match so that free money is not left on the table while you build cash. Three months suits a secure salary with a second income in the household. Six to twelve suits self-employment, commission-based pay, a single income, or a role that would take a long time to replace.

›Should I pay off debt or save first?

Expensive debt first. The UK flowchart clears anything above roughly 10% APR before the emergency fund gets built, because clearing a balance at 22% is a guaranteed, tax-free 22% return, and no savings account pays that. The widely shared American equivalent builds a small buffer before touching the debt, which is why you will see both orders argued online; this page follows the UK chart. Cheaper debt flips the other way: it gets the minimum payment and a written schedule while the emergency fund and the pension match take priority.

›Why is 10% APR the cut-off for overpaying debt?

It is a practical dividing line rather than a law. Above roughly 10%, clearing the debt beats any return you could reasonably expect elsewhere, and it is certain rather than hoped for. Below it, the maths gets closer, and keeping cash available or investing over a long horizon can be the better use of the money. Your own rate, term and circumstances decide it, and a low-rate debt you are anxious about is still worth clearing early.

›Where should short-term and long-term savings go in the UK?

Under five years the job of the money is to still be there, so it stays in cash: a savings account, a fixed term account if the date is certain, Premium Bonds, or a cash Lifetime ISA for a first home up to £450,000 if you are 18 to 39. Over five years the risk flips and inflation becomes the bigger threat, so a Stocks and Shares ISA, a Lifetime ISA, workplace pension contributions or a SIPP make more sense, with the £20,000 overall ISA allowance used first and a General Investment Account only once the tax-free allowances are gone. Those are 2026/27 rules, and two of them change: see what changes next, above.

›Is the cash ISA allowance being cut?

Yes, from 6 April 2027. The amount you can hold in a cash ISA falls from £20,000 to £12,000 a year if you are under 65. The overall £20,000 ISA allowance is unchanged, so the remaining £8,000 can still be used, but only in a Stocks and Shares ISA, an Innovative Finance ISA or a Lifetime ISA. From the tax year in which you turn 65 you keep the full £20,000 cash limit. Anti-circumvention rules arrive at the same time, including a flat 22% charge on interest paid on cash held inside a non-cash ISA, and a bar on transferring from a non-cash ISA into a cash ISA for the under-65s.

›Is the Lifetime ISA being scrapped?

It is being replaced, from around April 2028, by a First Time Buyer ISA. The new product is for buying a first home only, so the retirement purpose goes, and it is expected to be available as cash or Stocks and Shares, to drop the 25% withdrawal penalty, and to pay the bonus as a lump sum at purchase. That detail came out of a consultation in early 2026 and is not final. If you already hold a Lifetime ISA you can keep paying into it indefinitely and keep the 25% bonus, but existing Lifetime ISAs cannot be transferred into the new product. Opening one now can still be worth it. Building a ten-year plan on the current rules is not.

›Is this financial advice?

No. It is a general order of operations that suits most people most of the time, applied to figures you type in. It knows nothing about your job security, your health, your family, or anything else that should shape a real decision, and it cannot recommend a product. If you want advice on your own circumstances, speak to a qualified adviser. If you are struggling with debt, free and impartial help is available from StepChange and National Debtline.

Where to go next

This is not advice

This page is general information, not financial advice, and not a recommendation of any product, account or provider. It applies a widely used order of operations to figures you type in, and it knows nothing about your job security, health, family or tax position. Allowances quoted are for the 2026/27 tax year and were correct as at 24/08/2026; several are already scheduled to change, and announced changes that are still under consultation may not land as described. Investment values can fall as well as rise. Speak to a qualified adviser about your own circumstances, and if you are struggling with debt, contact StepChange or National Debtline for free, impartial help.

The flowchart gives you the order. It never shows you the consequence.

Knowing your next £100 goes at the 22% card is the easy half. The hard half is what that does to the deposit, the car, the childcare bill and the pension over the next ten years. CrestCast forecasts your whole household day by day, month by month and year by year, so you can watch the order of operations play out instead of taking it on faith.
