See how your savings or investments grow over time with compounding and regular contributions — entirely in your browser.
Enter a time horizon to see projected growth.
What you're starting with and how much you plan to add each month.
An expected annual return rate and how many years you're planning for.
Future value updates instantly, split into what you contributed vs. what compounding added.
Yes. Every calculation happens entirely inside your browser tab — nothing about your savings or contributions is ever sent anywhere.
Monthly compounding, with each month's contribution assumed to land at the end of that month (the standard "ordinary annuity" convention). Interest earned each month is added to the balance before the next month's growth is calculated.
That depends entirely on what you're saving in — a high-yield savings account, a diversified index fund, and a single stock all carry very different realistic return expectations. This tool doesn't recommend a rate; it just shows you the math for whatever rate you enter.
No, this is a projection based on the assumptions you enter. Actual investment returns vary and are never guaranteed.
