🔭 Future Value Calculator
Project what today's money will be worth later. Enter principal, rate, compounding, and years — or switch to regular contributions — to calculate forward future value before you invest.
Future Value of Lump Sum and Annuities
BrainyCalculators editorial insight — unique to this tool
FV = PV × (1 + r)^n for lump sums; ordinary annuity FV adds periodic payments. A $50,000 bonus invested at 7% for 20 years grows to ~$193,000 without additional contributions. Indian PPF uses government-set rates compounded annually — different from market-linked assumptions.
When to use this calculator
Use for goal-based projection of today's money forward. For regular mutual fund SIPs, use SIP.

What is Future Value (Forward Projection)?
Future value (FV) answers a forward-looking question: if I invest this amount today at this rate, what will it be worth in N years? The formula discounts time and compounding into a single projected balance — essential for retirement targets, education funds, and savings goals where you know the starting point and need the endpoint.
This calculator supports two modes: a lump-sum deposit with selectable compounding frequency, and a stream of regular contributions (annuity). It shows future balance, total contributions, and interest earned over the horizon. Use it when you are planning ahead from known inputs.
If you already know your starting and ending balances and want to measure how well the investment performed — total return, CAGR, or inflation-adjusted real return — use the Investment Return Calculator instead. FV projects forward; investment return analyses backward from results.

How the Future Value Calculator Works
Formula, assumptions, and calculation steps for this finance tool.
Methodology
Financial calculators use time-value-of-money, rate conversion, amortization, or return formulas depending on the tool. Inputs are normalized to matching periods before the final result is calculated.
Calculation Steps
- Enter the principal amounts, rates, terms, or cash flows requested by the calculator.
- Convert annual rates to the correct monthly, daily, or yearly period when needed.
- Apply the finance formula for payment, return, yield, or future value.
- Show the result with supporting totals such as interest, gain, or balance.
Assumptions and Limits
- Rates are assumed constant unless the calculator asks for a schedule.
- Taxes, fees, and inflation are included only when fields are provided.
- Financial results are estimates for planning, not investment or lending advice.
Frequently Asked Questions
Future value (FV) is the value of a current asset at a specified date in the future, based on an assumed rate of growth. It answers: If I invest $X today at Y% return, how much will it be worth in Z years?
More frequent compounding means interest is calculated and added to the principal more often, which leads to slightly higher future values. Monthly compounding yields more than quarterly, which yields more than annual. The difference grows larger with higher interest rates and longer time horizons.
The Rule of 72 is a shortcut to estimate how long it takes to double your money. Divide 72 by the annual interest rate. For example, at 8% per year your money doubles in about 72 ÷ 8 = 9 years.
Future Value (FV) tells you what a current sum will be worth later, while Present Value (PV) tells you what a future sum is worth today after discounting. They are the inverse of each other and use the same core formula rearranged.
