Comparison
CrestCast vs YNAB
This is not a feature-count contest, because the two products disagree about something more basic than features. YNAB thinks you should plan only with money you already hold. CrestCast is built to project money you have not received yet. Both positions are defensible. Which one suits you decides the whole question.
| CrestCast | YNAB | |
|---|---|---|
| Main job | Forecast where a UK household is heading, and test decisions against it | Give every pound you already hold a job, so this month adds up |
| Which way it looks | Forwards, over months and years | At now. Its own guide to irregular income has a section headed "Why Forecasting Doesn't Work" |
| What you plan with | Income and costs you expect, including ones that have not happened yet | Only money already in your accounts. Future months allocate cash in hand, not expected income |
| Bank connection | None. You enter what it knows, or import a CSV | Yes. Direct Import, which in the UK runs through Plaid or TrueLayer, plus a UK-only Apple Wallet route |
| Net worth | Forecast forwards, and benchmarked against ONS household data | Reported backwards, in its Reflect tab |
| Debt | Clearance dates for every debt in the household model | Loan Planner projects a payoff date for loans and mortgages. Its simulator is web only, and it is not designed for credit cards |
| Scenarios | Save versions of the plan and compare them side by side | Extra-payment what-ifs inside Loan Planner, and no scenario comparison beyond that |
| Sharing | One subscription covers the household, with joint, personal and household views | YNAB Together: up to six people on one subscription, you plus five, each with their own login |
| Price | £7.99/mo or £79.99/yr for the household | $14.99/mo or $109/yr, priced in US dollars, so UK customers pay in dollars. 34-day free trial with no card |
| Country | UK only | US company, incorporated in Utah, with a UK subsidiary. The UK is on its list of 18 European countries for bank feeds |
YNAB's prices correct as at 14/08/2026. Taken from ynab.com, with the rest of the row checked against its support documentation, its guides and its UK and EEA terms. YNAB prices in US dollars only, so what a UK card is charged moves with the exchange rate on the day and this figure cannot be stamped in pounds.

The real difference is not a feature, it is a philosophy
YNAB does not lack forecasting by accident. It rejects it on principle. Its own guide says forecasting “can result in a false feeling of financial control”, and its documentation tells you to plan using only the funds you have on hand right now. That is a coherent position, and for someone whose income is unpredictable and whose problem is overspending, it is very likely the right one.
But it means YNAB structurally cannot answer a whole class of question. Can we afford a bigger house in two years. What does one of us going part time do to the next five. When is this mortgage actually gone, and is overpaying it better than putting the money elsewhere. Those questions are about money that has not arrived yet, and a tool that only plans with cash in hand has nothing to say about them.
That is the gap CrestCast is built for. It projects a three-way model forwards, cashflow alongside profit and loss alongside net worth, and lets you compare two versions of the plan side by side before you commit to either. It also lives between budgeting apps and retirement apps, which is exactly the space a budget cannot reach.
The view YNAB says it will not give you
Figures shown are the sample profile, not a real household.
Where CrestCast is different, and what you would give up
The bank feeds are YNAB's. It will pull your transactions in; CrestCast never connects to your accounts, so you enter what you want it to know or import a CSV. That is more work, and it buys you a model that contains exactly what you chose, with no credential shared. Here is why we built it that way.
No envelope method, and no attempt at one. You can pin what actually happened in a month and the forecast re-reckons around it, but there is no budget to drift from and nothing that reports a gap against one, so it will not stop you spending in the moment the way YNAB is designed to.
Which should you choose?
Choose YNAB if the problem is this month: money disappearing, no idea where, an income that arrives at awkward intervals. Its method, give every pound a job, is teachable and changes behaviour, it has bank feeds, its subscription covers six people, and there is a 34-day trial with no card. Choose CrestCast if the problem is the next few years: a decision you cannot take back, a debt you want gone by a date, two incomes that need to be looked at as one household.
And if you want to see how the forecast handles a specific question first, the mortgage overpayment and debt payoff calculators are free and need no account.
Common questions
›Does YNAB do forecasting?
Not in the sense most people mean, and YNAB says so itself. Its own guide for irregular income contains a chapter headed "Why Forecasting Doesn't Work", and says forecasting "can result in a false feeling of financial control". Its support documentation tells you to "establish your plan using only the funds you have on hand right now, not anticipating future income". You can assign money into future months, but only money you actually hold, so the future view is an allocation of cash in hand rather than a projection of what is coming. The one genuinely forward-looking tool is Loan Planner, which projects a payoff date for a loan or mortgage.
›Is CrestCast a good YNAB alternative?
If you want a forecast, yes. If you want an envelope budget, no, and you should stay with YNAB. They are not competing implementations of the same idea. YNAB is a method for controlling the money you have this month, and it is very good at it. CrestCast is a model of where your household is heading over years, and it does not try to police your day-to-day spending. If the method is what you need, YNAB is where you will find it.
›How much does YNAB cost in the UK?
Checked on 14/08/2026, YNAB was $14.99 a month or $109 a year, and those are the only two options: there is no third tier and no sterling price. Its pricing page states plainly that "YNAB is priced in US dollars. Exchange rates are not reflected in the price", so a UK customer pays in dollars and absorbs their card's exchange rate and any non-sterling transaction fee. There is a 34-day free trial with no card required when you sign up directly, and students can get a free year with proof of enrolment. CrestCast is £7.99 a month or £79.99 a year in pounds, covering the whole household.
›Does YNAB work with UK banks?
Yes. The United Kingdom is on the list of European countries YNAB names for Direct Import, which ran to 18 of them when this page was checked on 14/08/2026. Worth getting the plumbing right, because it is widely reported wrongly: YNAB's own UK, Switzerland and EEA terms say that for a bank account in the UK or the EEA the Open Banking service is provided by Plaid Financial Ltd, and that you will be asked to agree to Plaid's or TrueLayer's terms and redirected to your bank by one of them. MX is named in YNAB's terms for the United States and Canada, not for the UK. There is also a UK-only route that connects through Apple Wallet on a recent iPhone. YNAB's own documentation notes the limits: not every account type falls under Open Banking, connections can break when a bank changes its security, transactions can take up to three days to appear, and history from before your starting balance is not imported. CrestCast does not connect to any bank at all, which is a deliberate choice rather than a missing feature.
›Can my partner and I share one subscription?
Both products allow it. YNAB Together puts up to six people on one subscription, being you plus five you invite, each with their own login and no extra charge. Worth knowing how the visibility works: members' plans are automatically shared with the group manager, while the manager chooses which of their own plans members can see. CrestCast is built round a household rather than a manager and invitees, so both partners see the same forecast, and it keeps a standing line between joint money and each person's own.
›Can I use both?
Yes, and it is probably the best answer if you like YNAB. Budget the current month in YNAB, forecast the next ten years in CrestCast. One tells you whether you can buy the thing this week, the other tells you what buying it does to the mortgage.

This is not advice
This comparison is independent and is not affiliated with, endorsed by, or sponsored by YNAB. Details about YNAB are drawn from ynab.com, its support documentation and its UK, Switzerland and EEA terms, checked on 14/08/2026, and may be out of date by the time you read this. Check YNAB's own site for current features and pricing, and note that its prices are set in US dollars, so the sterling cost depends on the exchange rate on the day. Nothing here is financial advice.
A budget tells you about this month. A forecast tells you about the next ten years.
CrestCast turns both incomes, the bills, the mortgage and the kids into one forward-looking picture, so the big decisions stop being guesses.
