Assumes a steady rate and monthly compounding. Real returns vary year to year.
How this works
Interest is added monthly and then earns interest itself — that's compounding. The calculator runs your balance forward one month at a time: it adds the month's interest, then your contribution, and repeats for the whole period.
The gap between what you put in and the final balance is pure growth, and it widens sharply the longer the money is left alone.
