Future Value Calculator
The future value calculator determines how much your money will be worth at a future point in time. Enter a starting investment (present value), an annual interest or growth rate, and a time period. The calculator can handle a lump sum alone or combined with regular monthly deposits. Choose which scenario matches your situation and see your money grow through the power of compound interest.
Future value formulas
Lump sum: FV = PV × (1 + r)^n
With deposits: FV = PV × (1 + r)^n + PMT × (((1 + r)^n - 1) / r)
where r = annual rate, n = number of years (for annual compounding)
How to use this calculator
- Enter your starting amount in "Present value".
- If you plan to add money regularly, enter your monthly contribution. Otherwise, leave it as 0.
- Enter your expected annual interest or growth rate in "Annual interest rate".
- Enter how many years you plan to invest in "Number of years".
- The calculator shows your future value broken down by source.
Understanding your results
Growth from initial amount shows how much your starting investment will grow through compound interest alone.
Growth from monthly deposits shows how much your regular contributions will accumulate, plus interest earned on those deposits.
Total future value is the sum of both components, representing your total account balance at the end of the period.
Future value calculator: frequently asked questions
What is future value?
Future value is the amount of money an investment will grow to at a specific date in the future, accounting for compound interest. It answers the question: how much will my money be worth in 10 years?
What is the difference between lump sum and regular deposits?
A lump sum is a single, one-time investment. Regular deposits are repeated investments (e.g., monthly contributions). Both grow with compound interest, but regular deposits build up over time.
How often is interest compounded?
This calculator assumes annual compounding. Some investments compound monthly, daily, or continuously. Check with your bank or investment provider for the exact compounding frequency.
Can I use this for bonds or CDs?
Yes, future value applies to any investment: savings accounts, bonds, certificates of deposit (CDs), stocks, or mutual funds. Use the interest rate your investment is expected to earn.
What if the interest rate is negative?
A negative rate means your investment is losing value. This could happen during inflation or if you are paying interest instead of earning it.
