# Financial Independence, Retire Early (FIRE) by Age Calculator

Use the Financial Independence, Retire Early (FIRE) by Age Calculator to compute and chart how much money you would accumulate by investing a given amount of money at a fixed rate of return starting at one age and stopping at another age and then letting that money grow.

The calculator has two phases:

*Recurring Investment Phase*during which a specified amount is invested each year beginning at a starting age and stopping at an ending age.*Compounding Phase*during which no new investments are made and the balances from the first phase compound for a specified number of years.

For both phases money grows at a specified annual percentage rate of return by compounding.

For example, if you invested $1,000 per year beginning at age 20 and ending at age 30 (11 investments), you would have $55,347 at age 65 given a four percent rate of return. The same investments growing at six percent would be worth $121,978 at age 65. At a ten percent rate of return the investments would be worth $572,848.

If you invested 1,000 per year beginning at age 31 and ending at age 65 (35 investments) you would have $76,598 at age 65 given a four percent rate of return. The same investments growing at six percent would be worth $118,121 at age 65. At a ten percent rate of return the investments would be worth $298,127.
