Calculate compound growth and interest instantly.
Use Bravunel's free compound interest calculator to estimate how an investment can grow over time. Calculate your ending balance, total contributions and interest earned.
Compound interest is interest earned on both your original investment and previously accumulated interest. Over time, this can allow your money to grow faster than simple interest.
Enter your initial investment, annual interest rate, investment period, additional contributions and compounding frequency. Bravunel calculates the estimated future value and shows how much comes from contributions versus interest.
