Example of How Retirement Calculator Works

When planning your finances for retirement, one key step is estimating how much monthly income you will need once you retire. A retirement planning calculator or retirement corpus calculator often uses the future value formula to factor in inflation and changes in expenses over time.

FV=PV×(1+r)∧n

Suppose Anita spends ₹40,000 per month and plans to retire in 20 years. She estimates an average inflation rate of 6% per year. Using a retirement plan calculator , Anita wants to determine the monthly income she’ll need at retirement

Calculation:

FV=40,000×(1+0.06)20

FV=40,000×(1.06)20=40,000×3.207=₹1,28,280

At retirement, adjusted for inflation, Anita will need approximately ₹1,28,280 per month to maintain her current lifestyle. This figure helps her plan the total corpus she needs to accumulate using a retirement corpus calculator or a retirement planning calculator.
