About the Investment Calculator
This Investment Calculator computes the future value of your money based on compound growth. Enter your starting amount, contribution schedule, expected return rate, and time frame, and it shows the projected balance, total contributions, and total earnings.
The calculator applies the standard compound interest formula FV = P x (1 + r)^n. For regular contributions, it adds the future value of an annuity formula, FV = PMT x [((1 + r)^n - 1) / r], applied per deposit period. Inputs include the initial investment, contribution amount and frequency, expected annual return, compounding frequency, and years of growth. A useful tip: run the calculation again with a return rate one or two percent lower to see how much the result depends on that assumption.
- Enter your initial investment and choose how often you will contribute.
- Set the annual return rate, compounding frequency, and number of years.
- Review the projected balance, then toggle dividend reinvestment to compare results.
