Explanation: The formula converts the annual interest rate to a monthly rate by dividing by 12, then applies it to the principal amount to calculate the monthly interest earned.
Details: Understanding how much interest your savings can earn helps with financial planning, comparing savings accounts, and setting realistic savings goals. It's particularly important in the UK where interest rates can vary significantly between financial institutions.
Tips: Enter your principal amount in pounds (£) and the annual interest rate as a percentage (%). All values must be valid (principal > 0, rate ≥ 0).
Q1: Is this calculation specific to UK savings accounts?
A: Yes, this calculator uses the standard method for calculating monthly interest on savings accounts in the UK, where interest is typically calculated monthly.
Q2: Does this account for compound interest?

A: While many do, some accounts pay interest quarterly or annually. Always check the terms of your specific savings account.
Q5: How accurate is this calculator for real-world applications?
A: This provides a basic estimate. Actual interest may vary based on specific account terms, compounding frequency, and any minimum balance requirements.
