Future value calculator
Calculate how much an investment will be worth in the future with compound interest growth.
Present value ($)
Annual rate (%)
Years
Future value formula
FV = PV × (1 + r)ⁿ
Where FV = future value, PV = present value, r = annual rate (decimal), n = years.
Example
$1,000 at 5% for 10 years: FV = 1000 × 1.05¹⁰ = $1,628.89.
Rule of 72
Divide 72 by the interest rate to estimate doubling time. At 6%: 72/6 = 12 years to double.
