Formula Explained

The money needed for retirement is calculated using the future value formula for an annuity:

Retirement Corpus Formula

Future Value = P × (1 + r)ⁿ + PMT × [(1 + r)ⁿ - 1] / r

Where:

P = Current savings
PMT = Annual contribution
r = Annual return rate
n = Number of years until retirement

This formula accounts for both your current savings and future contributions, compounded at the expected annual return rate.

Worked Example

Let's say you are 30 years old, plan to retire at 65, have $50,000 saved, contribute $10,000 annually, and expect a 7% annual return.

Using the formula:

Example Calculation

Future Value = $50,000 × (1 + 0.07)³⁵ + $10,000 × [(1 + 0.07)³⁵ - 1] / 0.07

Calculating each part:

(1 + 0.07)³⁵ ≈ 10.72
$50,000 × 10.72 ≈ $536,000
[(1 + 0.07)³⁵ - 1] / 0.07 ≈ 148.6
$10,000 × 148.6 ≈ $1,486,000

Total Future Value ≈ $536,000 + $1,486,000 = $2,022,000

This means you would need approximately $2,022,000 saved by age 65 to maintain your current lifestyle.
