Estimates for planning only. Returns are not guaranteed. This is not financial advice.
How to use it
- Choose a question: how much you will have, or how much to save each month.
- Enter your starting amount, a yearly return and the number of years.
- Read the result and the chart, which splits what you put in from the growth.
Good to know
Compound growth means returns earn returns. Time matters more than almost anything else, which is why starting early helps.
The return you enter is an assumption. Real investments go up and down, and savings accounts pay what the bank sets.
