Why savings rates vary
Interest rates on savings accounts differ by provider and account type - easy-access accounts typically pay less than fixed-rate bonds or notice accounts, which lock your money away for longer in exchange for a better rate. Rates also move over time with the wider interest rate environment, so shop around rather than assuming your existing account is still competitive.
This page assumes interest compounds monthly and ignores tax - most people's savings interest is covered by the Personal Savings Allowance, but higher earners or large balances may have tax to pay outside an ISA.
