Future Value Calculator
Input Parameters
The future value calculator shows what a sum of money today will be worth at a future date, given a specific interest rate and time period. It is the foundation of investment planning, retirement projections, and comparing the value of money across time.
Future Value Formula
FV = PV x (1 + r)^n
FV = future value. PV = present value (amount today). r = interest rate per period. n = number of periods. For monthly compounding: use r = annual rate / 12, n = years x 12.
Future Value of $10,000 at Various Rates
| Rate | 5 Years | 10 Years | 20 Years | 30 Years |
|---|---|---|---|---|
| 3% | $11,593 | $13,439 | $18,061 | $24,273 |
| 5% | $12,763 | $16,289 | $26,533 | $43,219 |
| 7% | $14,026 | $19,672 | $38,697 | $76,123 |
| 10% | $16,105 | $25,937 | $67,275 | $174,494 |
Future Value with Regular Contributions
FV = PV x (1+r)^n + PMT x [(1+r)^n - 1] / r
PMT = regular payment per period. Example: $5,000 today, $200/month, 7% annual, 20 years. FV = $5,000 x (1.07)^20 + $200/month contributions = $19,348 + $104,730 = $124,078.
The Rule of 72
Divide 72 by the annual interest rate to estimate how many years it takes to double your money. At 6%: 72/6 = 12 years. At 9%: 72/9 = 8 years. At 3%: 72/3 = 24 years. This rule works for rates between 6-10% and gives a close approximation without a calculator.
Frequently Asked Questions
What is future value?⌄
Future value is the worth of a current sum of money at a specific date in the future, assuming a given rate of growth. It answers the question: "If I invest $X today at Y% per year, what will it be worth in Z years?" It is the core concept behind investment projections and retirement planning.
How is future value different from present value?⌄
Future value calculates what money today grows to in the future. Present value works backward: it calculates what a future payment is worth today in today's dollars. Both use the same interest rate and time variables but answer opposite questions.
What is the future value of $1,000 in 10 years?⌄
At 5%: $1,629. At 7%: $1,967. At 10%: $2,594. The rate makes a dramatic difference over longer periods. Use FV = PV x (1+r)^n with your specific rate.
Does compounding frequency affect future value?⌄
Yes, but the effect is smaller than people expect. $10,000 at 6% for 10 years: annual compounding = $17,908. Monthly compounding = $18,194. Daily compounding = $18,220. More frequent compounding adds value, but diminishing returns apply — daily vs. monthly makes very little practical difference.
What rate of return should I assume for future value projections?⌄
Use conservative estimates for planning: 5-6% for a balanced portfolio, 7-8% for stock-heavy portfolios, 2-3% for bond or savings accounts. Always run projections at a lower rate to stress-test your plan. A projection based on 10% that actually delivers 6% can leave you significantly short of your goal.
