Compound interest is the interest you earn on both your initial investment (the principal) and the accumulated interest from previous periods. It is often called 'interest on interest' and is a powerful force for growing wealth over time. The key takeaway is that the longer your money is invested, the more significant the effect of compounding becomes. This Compound Interest Calculator from Calculator Site helps you visualise this growth year by year.
How to use this Calculator Site tool
Enter your initial investment amount, the annual interest rate you expect, and the number of years you plan to save for. Choose how often the interest is compounded (e.g., annually, monthly). The calculator will then show you the final amount and the total interest earned, along with a detailed year-by-year breakdown of your investment's growth.
Important Considerations for UK Savers
Interest rates are variable and can change. The rates used here are for illustrative purposes. In the UK, you have a Personal Savings Allowance (PSA) which allows you to earn a certain amount of interest tax-free. Interest earned in an ISA is always tax-free. For personalised advice, it is best to consult a financial advisor.
