Investment Calculator
Inputs and units
Use the units shown for Initial investment ($), Monthly contribution ($), Expected annual return (%), Investment period (years). Required fields cannot be blank. Use zero only where that field and the model allow it. Select Calculate after changing a scenario.
Method and assumptions
The starting balance compounds monthly. Contributions arrive at month end. Convert years to the nearest whole month. Total contributed equals the starting balance plus all scheduled deposits; growth is the ending balance less contributed money.
Worked example
Starting at 1,000, depositing 100 per month for one year at 0% produces 2,200, with no growth.
Limitations
The entered return is a constant nominal rate compounded monthly and must exceed -100%. Taxes, fees, inflation and dated irregular cash flows are excluded.
