Calculate the future value of a present sum of money, plus optional regular monthly contributions, at a given growth rate.
This tool calculates how much a current sum of money (or series of regular contributions) will grow to over time, based on an expected interest or growth rate. It's the foundation for retirement planning, savings goal projections, and general investment forecasting.
Future Value (lump sum) = Present Value × (1 + r)ⁿ. Future Value (with regular contributions) = Present Value × (1 + r)ⁿ + Contribution × [((1 + r)ⁿ − 1) ÷ r], where r is the periodic rate and n is the number of periods.
Enter your current amount (and any regular contributions), the expected growth rate, and the time period, and the calculator returns the projected future value.
Example: $5,000 invested today at a 7% annual return grows to approximately $5,000 × (1.07)^10 ≈ $9,835.76 after 10 years.
What's the difference between future value and present value? Future value projects how much money will grow to over time; present value works in reverse, discounting a future amount back to its equivalent value today — they're inverse calculations based on the same growth rate assumption.
Why does a small difference in growth rate matter so much over long periods? Compound growth means even small rate differences compound exponentially over time, so a 7% versus 8% return can lead to a substantially larger gap in outcomes over 20-30 years than the 1% difference might initially suggest.
Is future value calculation the same for all types of investments? The basic mathematical formula is the same, but actual future value depends heavily on the specific investment's realized return, which varies by asset type and market performance — the calculator's projection is only as good as the assumed rate.
How is future value used in retirement planning? It helps estimate whether current savings and contribution rates are on track to reach a specific retirement goal, allowing adjustments to contribution amounts or timeline if the projected value falls short of the target.
Does future value account for taxes and fees? Basic future value calculations typically show gross growth before taxes and investment fees, which can meaningfully reduce the actual net amount realized, so it's worth considering these factors separately in comprehensive planning.
