About bureau.money

bureau.money is a set of free UK money calculators for savings, ISAs, mortgages, loans and pensions. There's no sign-up, no download and no adverts, and every calculation can be shared as a link.

How the calculations work

Each calculator works month by month using standard formulas, which are explained in the “How it works” section on its page. UK rules such as ISA allowances, the cash ISA limit, pension tax relief and the Lump Sum Allowance are taken from GOV.UK and re-checked when they change.

How the figures are checked

The calculators are tested against independent calculations, including every worked example quoted in the FAQs, and with extreme inputs to make sure they never give nonsense results.

What bureau isn't

bureau is for information only and isn't financial advice. Results are illustrations based on the numbers you enter, and real returns, rates and rules change. For advice about your own situation, speak to a regulated financial adviser, or use the free guidance at MoneyHelper.
