Savings goal calculator
Saving for a house deposit, a car, a wedding or a rainy-day fund? Find out how much to put away each month, or how long it will take to get there.
How the calculator works
Your current savings and each monthly deposit earn interest, which is added every month. The calculator finds the monthly amount that reaches your goal exactly on time, or counts the months until your balance passes the goal.
Example
To turn £1,000 into £10,000 in 3 years at 4%, you need to save £232.38 a month. You pay in £9,365.77 in total and interest makes up the other £634.23. If you can only save £250 a month, you get there in 2 years and 10 months.
Where to keep your savings
- Easy-access savings for an emergency fund you might need at short notice.
- Regular savers often pay higher rates if you pay in every month, usually for one year.
- ISAs keep your interest tax-free. You can pay in up to £20,000 a year across all your ISAs.
