The Lifetime ISA (LISA) is one of the best ways to save for your first home. Use our calculator to see how much you could save when compared to the average market-leading easy-access savings account.

With a LISA, you can save up to £4,000 each tax year and get a 25% government bonus on top of these tax free savings. So if you pay in the maximum of £4,000 per year, the government will top it up with an additional £1,000! If you pay in £1,000 you’ll get £250.

You can do this every year until you reach 50 years of age, giving you a handy bonus to put toward your future home that you wouldn’t receive with a cash savings account. 

Our Cash Lifetime ISA offers a market-leading rate of 1.25% AER variable. If you already have a LISA, transfer it now to get the best interest rate.

Use our house buying calculator to see how much you could save for your first home with a Lifetime ISA vs cash savings account. Simply select in how many years time you would like to buy your first home and how much you can save per year, and we’ll work out the rest. 

See below for assumptions we’ve used, and remember that interest rates may change in the future.

It’s important you know:

If you need to withdraw money for any reason other than your first home or retirement, you’ll pay a government charge of 25% on any sum you withdraw. The effect of this charge is you’ll lose the government bonus plus £6.25 per £100 you contributed.

Please note that you must be aged between 18-39 in order to be eligible to open a Lifetime ISA account.
