Investment Calculator
Project a potential investment balance using an initial amount, monthly contributions, expected return and time horizon.
About the Investment Calculator
An investment calculator can help you visualize how an initial amount and regular contributions might grow over time under an assumed annual return.
How to use this calculator
- Enter your initial investment.
- Enter the amount you expect to contribute each month.
- Enter an assumed annual return.
- Choose the time horizon and review the projected value.
How the calculation works
The projection compounds the assumed monthly return over the selected number of months and adds the future value of recurring monthly contributions.
Example
An initial $10,000 investment with $500 added each month at an assumed 8% annual return over 20 years shows the potential effect of time and consistent contributions.
Things to keep in mind
- Investment returns are uncertain and can be negative.
- Taxes, fees, inflation, and account rules can affect actual results.
- Do not treat a projection as a promise of future performance.
- Compare conservative and optimistic assumptions.
Frequently asked questions
What return should I enter?
Use an assumption appropriate for the type of investment and your planning scenario. Consider testing several rates.
Does this account for inflation?
No. The displayed value is a nominal projection and does not subtract inflation.
Are market losses included?
The calculator uses a constant assumed return, so it does not model year-to-year market volatility.
