Compound future value
What will one amount invested today become after compounding?
When to use it and why it works
You invest principal today. Interest joins the balance each period and earns interest in later periods. Match the periodic rate to the number of periods, then multiply principal by the growth factor.
FV = PV × (1 + i / m)^(m × n)
Work through an example
Invest 10,000 at a nominal 5% rate, compounded annually for 3 years. Find the future total.
Read this example’s explanation
10,000 × 1.05³ = 11,576.25. Subtract principal to obtain 1,576.25 in total interest.
Your calculated answer
- Future principal plus interest FV
- 11,576.25
- Total interest / value change
- 1,576.25
Follow each step
Divide the decimal nominal annual rate by periods per year.
5 / 100 / 1 = 0.05Multiply periods per year by years to get total periods.
1 × 3 = 3Raise the per-period growth factor to the total number of periods.
(1 + 0.05)^3 = 1.157625Multiply today’s principal by the accumulated growth factor.
10000 × 1.157625 = 11,576.25Subtract today’s principal from future value to isolate the value change.
11576.25 − 10000 = 1,576.25

What the result means
FV is the future total, while interest is FV − PV. A positive rate grows principal; a negative rate can produce a loss of value.
Mistakes to watch for
- Use a nominal annual rate; an effective annual yield cannot simply be divided by m. Keep present and future amounts in one currency.
- The per-period growth factor 1 + i/m must be positive. Fractional m × n uses a geometric extension, not a bank payment schedule or stub-period convention.
- This is one lump sum at a constant rate with reinvestment. Taxes, fees, inflation, later deposits, and withdrawals are excluded.

Set up the formula first. Answers rounded to two decimals are accepted; use six decimals for absolute values below 0.01. For percentages, enter the number before the percent sign.
How to use this calculator
Enter Solve for, Present value, Future value, Annual rate, Years, and Compounds per year.
Review the model boundary before calculating: The calculation assumes the entered rate stays fixed for the full period.
Read Present value, Future value, and Compound factor, then compare the result with the cited source and governing product terms.
Formula
Formula used: PV = FV / (1 + i / m)^(m × n); FV = PV × (1 + i / m)^(m × n). Percentages are converted to decimals before calculation.
Worked example
Example: with Future value = 10,000, Annual rate = 5%, Years = 3, and Compounds per year = 1, the calculated Present value is 8,638.38.
Assumptions and limits
- The calculation assumes the entered rate stays fixed for the full period.
- Rates, cash flows, compounding, and measurement periods must use a consistent time basis.
- Recheck dated source rules, product documents, and market conventions before relying on the result.
