How This Calculator Works

This calculator shows how inflation affects your investments over time. The “Future Value” is what your investment will be worth in future dollars, while “FV Adjusted for Inflation” shows what that amount would be worth in today’s dollars after accounting for inflation.

You can use this tool to check how your money grows over time and how inflation (when prices go up) affects it. You can find out:

  • How much your money will be worth in the future.
  • How much that future money is worth in today’s money.
  • Or, how much you need to save now to reach a certain amount in the future after considering inflation.
  • Initial Investment (PV) – The present value or principal amount to be invested.
  • Target Future Value – The inflation-adjusted future value (FV) of your investment account.
  • Number of Years – How long is this investment? Decimals are allowed, for example, 6.5 years is 6 years 6 months; 2.25 years is 2 years 3 months.
  • Contributions – This is the amount of periodic deposits you will make to your account over the time of your investment.
  • Frequency – Calendar periods that contributions will be made (e.g., Monthly, Quarterly, Annually, etc.).
  • Annual Interest Rate – The annual nominal interest rate or “stated rate” in percent. r = R/100, the interest rate in decimal.
  • Compounding – The frequency with which compounding will occur (e.g., Monthly, Quarterly, Annually, etc.).
  • Annual Inflation Rate – The average rate of inflation you expect over the time period of your investment. You can calculate the average inflation rate of the past to make an estimate.

Example: Planning for Retirement

Imagine you want $250,000 to live comfortably when you retire. But you will retire 10 years from now. You want to know how much money you need to save today to have the same value as $250,000 in today’s money.

  • Suppose your investment earns 5% interest per year (interest added daily).
  • Inflation (price increases) is expected to be 2.25% per year.
  • You will not add any more money to this investment.

What to enter in the calculator:

  • Target Future Value: 250,000
  • Number of Years: 10
  • Contributions: 0
  • Frequency: NA
  • Annual Interest Rate: 5%
  • Compounding: Daily
  • Annual Inflation Rate: 2.25%

Results you get:

ItemAmount
Money to invest today$189,616.91
Money in 10 years$312,300.86
Value in today’s dollars$250,000.00

What it means:

If you invest $189,616.91 today, in 10 years your account will show $312,300.86. But because prices go up (inflation), that amount will be worth $250,000 in today’s money, which is what you need for your retirement goal.
