Compound interest calculator
Project how your savings could grow with compound interest: set the starting capital, the monthly contribution, the estimated annual return and the number of years, and watch the year-by-year evolution.
The power of compound interest
With compound interest, the interest you earn is added to the capital and then earns interest of its own. That reinvestment makes growth exponential: over time, the interest ends up contributing more than the contributions themselves. That is why the most important factor is not the amount, but starting early and being consistent.
The calculator compounds monthly: each month it applies the proportional return to the balance and adds the contribution. The table shows how the money you put in compares with the accumulated interest, year by year.
