Savings Goal Calculator
Got a goal, a holiday, a house deposit, a rainy-day fund? Tell us the target and the deadline, and we'll show exactly what to put away each month to get there, interest and Lifetime ISA bonus included.
Estimate only. Projections assume a constant interest rate and are estimates, not a guarantee. Savings rates change, and investment values can fall. Lifetime ISA rules and penalties apply, check gov.uk. Not financial advice.
Set a goal to see your monthly target
Enter a target amount and a deadline, we'll do the maths, including interest and any LISA bonus.
How we work out your monthly saving
We use the standard compound-interest (annuity) formula, assuming you pay in at the start of each month and interest is added monthly. Starting from what you've already saved, we solve for the exact monthly amount that grows to your target by the deadline. A higher interest rate or a longer timescale means you need to put away less each month.
If you choose the Lifetime ISA option, we add the 25% government bonus on your contributions (up to £4,000 a year), which cuts what you need to save. A Lifetime ISA is for buying a first home worth up to £450,000 or for retirement, withdrawing for anything else carries a 25% penalty, so only use it for those goals.
