Compound Interest CalculatorThis compound interest calculator shows how your money can grow when the interest you earn starts earning interest of its own. Enter a starting balance, a regular monthly deposit, an annual interest rate and the number of years, and you will see the projected balance and how much of it is growth rather than your own contributions. It is built for anyone planning ahead in the UK: savers building an emergency fund, parents saving for a child, or investors testing how a long-term pot might develop. It is a forecasting tool, not a tax calculator, so the figures depend entirely on the rate and deposits you choose.

Gilt Ladder CalculatorSpread a lump sum across gilts maturing in successive years, so cash comes back to you steadily - and tax-efficiently, since gilt gains are free of Capital Gains Tax. Build your ladder and see the year-by-year maturity schedule.
Gilt Yield Calculator (After-Tax)Work out the real, after-tax return on a UK government gilt - and see the savings rate you'd need to beat it. Because gilt capital gains are free of Capital Gains Tax and only the coupon is taxed, a low-coupon gilt bought below £100 can comfortably out-earn a taxed savings account, especially for higher and additional-rate taxpayers.
Gilt vs Savings vs ISA CalculatorWhere should your cash live? Compare the after-tax return on the same lump sum across a taxed savings account, a low-coupon gilt (gain CGT-free), a cash ISA and Premium Bonds - and see the clear winner for your tax band.
Index-Linked Gilt CalculatorIndex-linked gilts ("linkers") protect your buying power: the principal grows with inflation on top of a real yield. Project the nominal value at maturity and see the inflation-proof real return.
Personal Savings Allowance CalculatorOur personal savings allowance calculator shows how much of your savings interest is tax-free and estimates any tax due on the rest. It works out your Personal Savings Allowance (£1,000/£500/£0) alongside the £5,000 starting rate for savings, so you can see exactly where you stand for the year. Your allowance depends on which income tax band you fall into, and lower earners may pay no tax on savings at all. Enter your income and interest below to check your position in seconds.
Premium Bonds CalculatorUse our free Premium Bonds Calculator to get an instant estimate.
Lifetime ISA CalculatorA Lifetime ISA (LISA) gives you a 25% government bonus on up to £4,000 a year - up to £1,000 of free money - to put towards your first home or retirement. This calculator projects your pot, including the bonus and any investment growth, year by year.
