This tool adds up your contributions and the 25% government top-up to show what a Lifetime ISA is really worth over time. Its main limitation is that it ignores any interest or investment growth on the money itself — a stocks-and-shares LISA or a cash LISA paying interest will do better than this simple sum, so treat the total as a floor, not a forecast.

The Lifetime ISA is for first-time buyers (property up to £450,000) or for retirement. Withdraw for any other reason before age 60 and you pay a 25% early withdrawal penalty — this claws back not just the government bonus but a slice of your own money too.
