Frequently Asked Questions
What can this calculator solve for?
Any one of five things: the future value, the starting amount, the monthly contribution, the annual return rate, or the number of years. Enter the others and it finds the missing one.
How often does it compound?
It compounds monthly and adds your contribution each month, which matches most investment and savings accounts.
How is the required return rate found?
The calculator searches for the rate that grows your starting amount and contributions to your target by the end of the period. It is the steady annual return you would need.
Are the results guaranteed?
No. They assume a steady return every year, while real markets rise and fall. Use the figures to compare plans, not as a promise.
Is my information sent anywhere?
No. Everything runs in your browser. Your numbers never leave your computer and it works offline once loaded.
Can I use it for any currency?
Yes. The math is the same in any currency. Amounts show a dollar sign, but the figures are correct whatever you invest in.
