The Retirement Formula

The retirement savings formula used in this calculator is based on the present value of an annuity. The formula is:

Retirement Savings = Annual Expenses × [(1 + r)^{(n - m)} - 1] / r

Where:

Annual Expenses - Your expected annual retirement expenses
r - Expected annual return on investment (expressed as a decimal)
n - Retirement age
m - Current age

This formula calculates the amount of money you'll need to save today to have enough money to live on for the rest of your retirement.

Worked Example

Let's look at an example to illustrate how the calculator works. Suppose you are 35 years old and plan to retire at age 65. You expect to spend $50,000 per year in retirement and have an expected annual return of 5%.

Using the retirement formula:

Retirement Savings = $50,000 × [(1 + 0.05)^{(65 - 35)} - 1] / 0.05

Retirement Savings = $50,000 × [(1.05)³⁰ - 1] / 0.05

Retirement Savings = $50,000 × [2.1589 - 1] / 0.05

Retirement Savings = $50,000 × 1.1589 / 0.05

Retirement Savings = $50,000 × 23.178

Retirement Savings = $1,158,900

This means you would need to save approximately $1,158,900 today to have $50,000 per year in retirement.
