Lifetime ISA: cash vs stocks and shares

Stocks and shares lifetime ISAs are invested in the stock market and aim to make investment returns, while cash lifetime ISAs earn interest and aren’t invested

If you're thinking about using a lifetime ISA to save for your first home, have you thought about whether to open one that saves in cash or one that invests in stocks and shares?

What is a lifetime ISA?

A lifetime ISA is an ISA with a difference - it's designed to help you buy your first home or save extra for retirement and comes with a government bonus worth up to £1,000 a year.

You'll get a 25% government bonus on top of everything you pay into a lifetime ISA. So, the more you pay in, the more the government pays in.

As you can save or invest up to £4,000 of your £20,000 ISA allowance each year in a lifetime ISA, that's up to £1,000 a year available as a free government bonus!

You can open a stocks and shares lifetime ISA, which invests your money on your behalf, or a cash lifetime ISA which earns an interest rate. Let's dive into the differences.

Cash lifetime ISA or stocks and shares lifetime ISA – what’s the difference?

Just like other types of ISA, lifetime ISAs can be saved in cash or invested in stocks and shares. You can open both but you'll only be able to pay into one of them each tax year.

What is a cash lifetime ISA?

Cash lifetime ISAs grow by earning interest, like some savings accounts do. They increase with interest rates, so when you see on the news that interest rates have dropped, that's bad news if your savings are in a cash ISA and your account's interest rate isn't fixed.

Risk-wise, they are fairly safe. The amount of money in your ISA can't go down so there's no risk of you ending up with less money than you put in.

But there is another risk to be aware of: inflation. If the interest rate you're getting is lower than prices are going up by, your money is essentially losing value.

This can be a concern particularly if house prices are going up while you're saving a deposit.

What is a stocks and shares lifetime ISA?

Stocks and shares lifetime ISAs aim to make money by investing in the stock market.

"Investing" typically means paying your money into an investment fund along with other investors' money. The investment fund is used to buy various different types of investments: things like shares in companies, property and corporate and government bonds.

Your money increases or decreases as the value of those assets changes. This gives your money better potential to keep with, or even beat, inflation, than it would have in a cash lifetime ISA.

But as the value of your account is likely to go up and down over time, there is a risk that you could have less money in your account than you've paid in when you come to withdraw.

So, you have more potential to make money, particularly if you're investing for five years or more, but also more risk of the value going down.

Can I have a stocks and shares lifetime ISA and a cash lifetime ISA?

Technically yes, but you can only open one lifetime ISA during each tax year and you can only pay into one each tax year. So, you can't claim the bonus on two lifetime ISAs at the same time.

Need-to-knows before opening a lifetime ISA

  • You must use your lifetime ISA to buy your first home or leave it invested until you turn 60 (otherwise you'll need to pay a government withdrawal charge).
  • If using a lifetime ISA to build retirement savings, instead of a pension, you could lose out on employer contributions.
  • If you're a first-time buyer looking to buy your first home soon, a cash lifetime ISA might be more appropriate.
  • Your lifetime ISA should only be used to buy your first home after it has been open, with money in it, for at least 12 months (if you withdraw before then, you'll be charged the government withdrawal charge).
