Working Principle

The calculator uses the future value of an ordinary annuity formula to estimate the total amount of money you will have saved by the time you retire. It then adjusts this amount for inflation to give you a more realistic estimate of the purchasing power of your savings.

The formula used is:

Future Value = Annual Savings * [(1 + Investment Rate)^(Years to Retirement) - 1] / Investment Rate * (1 + Investment Rate)^Inflation Rate
