Live · Built for UK households

Stop guessing,
start planning.

CrestCast is the only UK planning app that gives a household all three financial statements, not just a budget: where the cash actually goes, what you own and what you owe, and whether you are genuinely better off each year. Ten years ahead, from the real numbers you type in.

Ask it what you are actually weighing up. Could we afford the bigger house? Can one of us go part-time when the baby comes? Overpay the mortgage, or invest it? It plays each answer through your own numbers and shows you what you would have, what you would owe, and when each debt clears, one, five and ten years from now. So you know where you are headed, and what it would take to change it. Run by you, and one subscription covers you and your partner.

Try it free for 14 days, no card needed to start. Then £7.99 a month, or £79.99 a year for a 17% saving, one subscription for your whole household. Cancel any time.

Or click around it yourself

The demo opens on a worked example household: a mortgage on a fix that runs out, a credit card about to revert off 0%, a partner, and two children's savings pots. Switch between personal, joint and household, move the date years forward, open any statement down to its line items, and see what a £300 a month overpayment does to the mortgage.

No account needed. The figures are a sample household, not a real one.

Run it yourself

Serious planning, without handing it over

The usual answer to a complicated financial life is to pay an adviser a percentage of it, every year, to model your future and hand you the conclusions. CrestCast gives you the same kind of forward-looking model for a fixed monthly price, driven by you: see the workings, change any assumption, and keep the decisions.

It is a planning tool, not a financial adviser. It does not recommend products or tell you what to do. It shows you what each option does to your money, which is usually the part that was missing.

How it compares with paying an adviser →

You'll get the most from it if

  • There is real money moving: a mortgage, savings, a pension or two, perhaps investments or a second property.
  • You want to know where you stand, not assume it is probably fine.
  • You'd rather see the numbers than be handed a conclusion.
  • You think in years, not just in months.
  • Decisions are coming that you want to test before you commit to them.
  • You want one place holding the whole picture.
  • You plan with someone, and it's easier to show them what a decision means than to talk them through it.

No accountant needed, and no expertise either. Being interested in your own money is enough.

The three-way forecast

Three views of the same future

Every business, from the corner shop up, runs on the same three statements, because strip the jargon off and they answer three plain questions: will the cash last, is more coming in than going out, and are we worth more than we were? A household makes decisions every bit as big, relative to what it has, and CrestCast is the only money app that builds all three for a UK household. It asks those three questions of your next ten years. In your words, about your life.

Cashflow forecast

Will the money be there when it's needed?

Your projected bank balance over time, right down to the day. Salary landing, bills going out, the month when the insurance, the birthday and the boiler all arrive at once. You see the squeeze coming while there's still time to do something about it.

How the cashflow forecast works

Profit & loss forecast

Are we actually building wealth?

Income against outgoings, played forward across the years. This is where a decision shows its real effect: what moving home, a new car or a few months on one income does to what's left over each month, and whether that surplus works hardest clearing a debt or growing a pot.

How the P&L forecast works

Net worth forecast

Where do we stand, and where will we?

Everything you own against everything you owe: where you stand today and, combined with the P&L, where you'll stand in five or ten years. Debts shrinking, savings and pensions building up. One line that tells you whether the plan is working.

How net worth tracking works

The forecast runs a full ten years ahead, far enough to hold the plans you're actually making. A bill that ends, or a salary that stops years from now with a pension drawn in its place: put the date in and all three views carry it from then on. Set the milestones you're aiming for and watch the forecast close in on them.

A pound in ten years is not a pound today, so every view can switch to today's money. And no figure is a black box: every balance can show its workings, built from the payments, the interest and the dates you entered. If CrestCast can't trace a figure back to something you typed, it doesn't show it.

One subscription, the whole household

Plan it together, from the same numbers

Big money decisions are rarely made alone, so CrestCast isn't priced per person. One subscription covers your household. Invite your partner and you're both reading the same forecast, the same debts and the same dates, which turns the big conversations from two half-pictures into one shared one.

A partner invite is included

No second seat to buy, no upgrade to find. Your subscription comes with an invite, so cost never decides who gets to see the plan.

Personal, joint and household views

One plan read three ways: your own position, the joint accounts, and the two of you combined. You can each see where you stand and where the household stands.

Children in the picture too

Give each child their own account and CrestCast projects it forward to the target age you pick, in today’s money as well as future pounds.

You choose what to share

Sharing is yours to set and yours to change whenever you like. Planning together never means giving up control of your own data.

UK income tax & NI
Scottish bands included, calculated automatically
Student loan plans
Plans 1, 2, 4, 5 and Postgrad

Five things you will use most

Clearing debts and building wealth are one plan sharing the same pounds. Each of these reads from the same forecast, so change a number anywhere and the whole picture moves together.

Clearing your debts

When will we finally be free of this?

Drill into any mortgage, loan, credit card or student loan. See the exact month it clears, the total interest it will cost you before it does, and what overpaying a little each month would change.

Learn more →

Trying it before you commit

What happens if we do this instead?

Model what-if changes: a different salary, going part-time, a bigger mortgage, moving house. Keep as many named versions of your plan as you like, then put two of them side by side and read the difference before you decide.

Learn more →

Where the spare money goes

What should we do with what is left?

Set a minimum to hold in the current account, then send what sits above your target down an order you choose: emergency fund first, then the expensive card, then the ISA. When a month goes badly the forecast draws back up to that minimum instead of quietly going overdrawn.

Learn more →

The dates you are already carrying

What happens when the fix ends?

The things you know are coming, put on a date rather than in your head: a fixed rate ending, the car finance finishing, childcare changing in September, a pay rise in April, a house sold. Each one lands in the right month and every view carries it from there on.

Learn more →

Keeping the plan honest

Are we ahead of the plan, or behind it?

When real life lands, pin what actually came in or went out for a month and the forecast re-reckons from there. Your plan and your reality stay in step, so the numbers ahead always start from what truly happened.

Worked example: your forecast shouldn't go overdrawn →One household, run ten years forward twice. A spreadsheet takes their current account to minus £27,752 while £32,000 sits untouched in savings, because a spreadsheet cannot move money between accounts. Both charts are the forecast engine's own output, with the whole household published so you can rebuild it.

Where CrestCast fits

Built for the next 1-10 years of your household's finances

Budgeting apps show you where your money went. CrestCast shows you where it is going: the next one to ten years, worked out from your real salary, mortgage, bills and plans, so you can see what a decision does before you make it. That window is too near-term for a retirement calculator and too far ahead for anything that only looks backwards.

A budgeting app

Answers: where did last month go?

  • Tracks spending by category
  • Flags the budget you went over
  • Keeps this month on the rails

Good at exactly that. But it reads the past, so it can tell you what happened, not what a decision would change.

CrestCast

Answers: what would this decision do to us?

  • Shows what you will have, earn and owe over the next decade
  • Shows the month every debt clears
  • Plays a what-if through the whole picture before you commit
  • Covers both of you: personal, joint and household views
A retirement calculator

Answers: will there be enough at 68?

  • Projects a pension pot decades out
  • Tests a growth rate and a retirement age
  • Right for the final stretch

Also good at its job. But it starts at retirement, and the decisions between now and then are out of its scope.

None of this rules out the long term. Pensions and investments sit inside the forecast and are carried through it, so if you're nearer retirement it will still show you where you stand over the next ten years. It simply isn't a dedicated drawdown or annuity calculator; it's built first for the decisions of the next decade.

And against the apps you already know

Here they are on the one question that separates them: how far ahead does each one actually look, and at what? Every cell was checked against each company's own site, help centre, App Store listing or filed accounts, never against another comparison blog.

Two things before you read it. A longer horizon is not a better one, and CrestCast does not have the longest here: we cap it at ten years on purpose, because past a decade a forecast stops being a plan and becomes arithmetic. Here is the whole argument. And CrestCast does not connect to your bank, which most of the others do. If a feed is what you want, one of them is the better answer and this table should help you pick it.

AppHow far ahead it looks
CrestCastTen years, day by day
SnoopA bills-against-balance timeline to month end, plus a 15-year savings projection. No household cashflow forecast
EmmaTo the end of the current month. Its True Balance nets an account against known upcoming payments
PlumA goal or retirement outcome, expressed as one monthly contribution figure. No month-by-month balance
MonzoOne figure: what is left to spend this period after upcoming payments
YNABNone, on principle. It argues against forecasting in its own guides
PocketSmithSix months to 60 years, by tier. Weekly steps beyond three months
