How to calculate compound interest

Our calculator requires you to input the initial amount (principal), the interest rate, the number of times interest is compounded per year, and the time period for which the interest will be calculated. With this information, the calculator can provide you with an estimate of the final amount that will be accrued.

This tool is particularly useful for individuals, investors, and financial professionals to plan and strategise for savings, investments, business loans, and other financial endeavours. It enables one to see how different interest rates and compounding frequencies can impact the growth of their money over time.
