One subscription. The whole household.

The two options buy exactly the same thing. Monthly keeps it flexible. Annual is £15.89 cheaper over twelve months, which is a 17% saving, or roughly 2 months free.

Both prices are inclusive of VAT where applicable. Payments are handled by Stripe and CrestCast never stores your card details.

It is not marketing shorthand for a single login shared between two people. 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.

What one subscription actually covers

The usual 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 £7.99 a month for the household. 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.

£7.99 a month, or £79.99 a year, and the two buy exactly the same thing. One subscription covers the whole household, and you can cancel at any time from your account settings.

You can try it before paying: every new account gets a 14-day free trial with full access, and no card is needed to start it. A card is required when you subscribe, through Stripe, and the free period is 14 days in total: subscribe on day ten and the remaining four days are still free, rather than a fresh trial starting.

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 are no contracts 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. If you delete your account, all associated personal and financial data is permanently deleted within 30 days. 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.
