How this savings growth calculator works
This savings growth calculator estimates how your money could grow over time. It uses your starting balance, monthly contribution amount, expected annual return, and number of years to project a future savings balance.
Savings growth can come from two sources: the money you contribute and the growth generated on those contributions over time. The longer you save and the more consistently you contribute, the more powerful compounding may become.
This calculator assumes monthly contributions and monthly compounding based on the annual return you enter. It is designed to help you explore how regular saving habits may affect long-term growth.
It does not account for taxes, inflation, investment fees, contribution changes, or market volatility. Real-world results may be higher or lower depending on actual returns and changes in your savings behavior.
How to use this calculator
Enter your current savings balance, the amount you plan to contribute each month, your expected annual return, and the number of years you want to save. Then click Calculate to see your estimated future balance.
What your estimate means
Your estimate shows the projected future value of your savings based on the numbers you entered. It also breaks out how much of the total comes from your own contributions versus estimated growth.
Example savings growth scenario
For example, someone starting with $10,000, contributing $500 per month, earning a 6% annual return, and saving for 20 years could build a much larger balance over time through a combination of steady saving and compounding growth.
