Savings booster

Use the Which? Savings Booster tool for a quick and easy way to see how much more interest you could be earning on all of your savings accounts.

Use the Which? Savings Booster to discover how much extra interest you'd earn by switching provider. Our tool covers all variable-rate savings accounts, except children's. 

You can compare rates on savings up to £100,000, although remember the Financial Services Compensation Scheme (FSCS) only offers a safety net of up to £85,000. 

Any savings you hold above this with a single provider are not guaranteed if they go bust - and remember multiple brands may belong to the same financial institution. See who owns who in the savings market to keep all of your savings safe. 

If you need a hand finding the best savings account for you, or help with any other aspect of your finances, sign up to a £1 trial with Which? and you can speak to a member of our Money Helpline team to get individual guidance. If you're already a Which? member, you can call for free for unlimited guidance on 01992 822848.

What are the best savings rates for you?

Use this tool to help you decide.
