How it works
Use this calculator to project how an investment may grow over time with recurring contributions.
What this calculator does
The investment growth calculator estimates ending value, total invested, and projected growth.
It uses:
- starting investment
- monthly contribution
- annual return
- years invested
Investment Growth Formula
FV = PV x (1 + r)^n + PMT x (((1 + r)^n - 1) / r)
Where PV is the starting investment, PMT is the recurring contribution, r is the monthly return, and n is the number of months.
Example calculation
If you start with 10,000, add 500 per month, earn 7%, and invest for 20 years, the calculator estimates the ending value and separates your contributions from growth.
When to use this calculator
- planning long-term investing
- comparing contribution levels
- testing different return assumptions
- estimating compound growth
FAQs
Is the return guaranteed?
No. The return is an assumption for planning, not a promise.
Does this include taxes?
