One subscription. The whole household.

Pay monthly to keep it flexible, or yearly and save £15.89. Either way the free trial comes first:

1. Days 1 to 30
   Free trial, full access

   Build the whole household picture and see what it tells you.

2. The charge
   £7.99 a month or £79.99 a year

   Only if you subscribe, for everyone in the household. Annual saves £15.89 a year, about two months free.

3. The next 14 days
   Change your mind and it comes back

   Email us within the window, whatever the reason, and we refund the payment in full.

After that your subscription runs to the end of the period you have paid for, and cancelling stops the next renewal. The right to change your mind is written into the terms, along with the price. It is inclusive of VAT where applicable, payments are handled by Stripe, and CrestCast never stores your card details.

Your subscription includes an invite for your partner. They sign up with their own account and their own password, join your household, and are covered by your subscription. Neither of you is ever logging in as the other, and neither of you is buying a second plan.

Once you are linked, the forecast covers both of you. You can look at the household as a whole, at the joint money on its own, or at either person individually, which matters because most couples do not pool everything. A joint account for the shared bills and personal accounts for the rest is exactly how the model is built. More on that on the couples page.

Children are included on the same subscription too. Add each child, give their account a balance and a monthly amount, and CrestCast projects what it grows into by the target age you pick, shown in today’s money as well as future pounds. There is no per-child charge and no family add-on. See the families page for how that fits together.

Some apps price by person. Emma's Ultimate plan, for example, lets you add up to four members at £5.99 each a month. CrestCast is £7.99 a month or £79.99 a year for the household, however many of you are in it. Prices checked on 15/10/2026 at emma-app.com; the products differ, see CrestCast vs Emma.

One answer to a complicated financial life is to pay somebody a percentage of it, every year, to model your future and explain what it means. That works, and for some people it is the right call. It is also a bill that grows every time your net worth does, for work that does not get proportionally harder.

CrestCast is a fixed price for the household, £7.99 a month or £79.99 a year. The same figure whether the forecast is showing you a good year or a bad one, and the same figure at any level of wealth. You can 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.

And the price is the whole of it. There are no tiers and no add-ons, and no bank, lender, insurer or fund manager pays us anything: what is on this page is everything CrestCast has to sell you.

We do share it in one direction. If somebody recommended CrestCast to you, we pay them part of what you pay us, out of the price on this page rather than on top of it. It costs you nothing, and it cannot change a single figure in your forecast. The programme is on the affiliate page and its full terms are public.

You can try it before paying, with full access. A card is required when you subscribe, through Stripe, and the free period does not restart: subscribe on day ten and the remaining 20 free days still apply.

The prices on this page are the same figures written into the terms. Separately, every calculator on this site is free to use with no account at all.

You can cancel at any time from your account settings. There is no minimum term and no lock-in. Cancellation takes effect at the end of the current billing period, and subscriptions renew automatically at the end of each period unless you cancel first.

Your financial data stays yours. CrestCast claims no rights to it, and you can export it or delete it outright at any time from your account settings, so nothing is stranded behind a subscription you have stopped. Deleting your account is not instant, on purpose: we wait 30 days, so signing back in during that time cancels it and leaves everything exactly as you left it. After the 30 days, all associated personal and financial data is permanently deleted. If CrestCast were ever discontinued you would get at least 30 days of notice and a means to export everything. The privacy policy sets out how it is stored in the meantime, and CrestCast never connects to your bank, so it only ever holds what you chose to put in.
