How this calculator works
The projection compounds the starting balance monthly and treats each contribution as an end-of-month deposit. Actual investment returns vary and are not guaranteed.
Worked example
Starting with $10,000 and adding $250 monthly for 10 years at a 7% annual return grows to roughly $63,000 with monthly compounding.
Frequently asked questions
Are contributions made at the start or end of each month?
This calculator assumes end-of-month contributions.
Can I enter a negative return?
Yes, down to -99% annually, to model declining value.
Are taxes and investment fees included?
No. Subtract expected fees or taxes from the annual return for a more conservative estimate.
