How compound interest works
Interest earns interest: each month, the return is calculated on what you started with plus everything earned so far. Add a regular contribution and the effect grows with time, which is why starting early matters more than the amount.
The table shows, year by year, how much you put in and how much came from interest.
Keep in mind
Investment returns vary from year to year and can be negative; this calculator assumes a constant rate.
Inflation reduces what the final amount will buy.
Fees and taxes reduce the real return.
Frequently asked questions
What return should I use?
For a savings account, its interest rate. For investments, a cautious long-term average; past returns do not guarantee future ones.
Monthly or yearly compounding?
This calculator compounds monthly, which matches monthly contributions.
Why does the interest part grow so fast at the end?
Because every year interest is earned on a larger total, including previous interest. That is the compounding effect.
