Reviewed by Calculator Editorial Team

Retiring early is a financial goal that requires careful planning. Our calculator helps you determine how much money you need to save to achieve financial independence at your desired age. This guide explains the formula, assumptions, and practical steps to reach your retirement goals.

How to Use This Calculator

To use the retirement savings calculator:

  1. Enter your current age
  2. Enter the age you want to retire

The calculator uses the future value of an annuity formula to determine how much you need to save now to support your desired lifestyle in retirement.

The Formula Explained

The formula used in this calculator is based on the future value of an annuity:

Future Value of Annuity = PMT × [(1 + r)^n - 1] / r

Where:

  • PMT = Annual retirement expenses
  • r = Expected annual return (as a decimal)
  • n = Number of years in retirement (retirement age - current age)

This formula helps determine how much you need to save now to have enough money to live on in retirement, assuming your investments grow at the expected rate.

Worked Example

Let's say you're 30 years old and want to retire at 55. You expect to spend $50,000 per year in retirement and your investments are expected to grow at 5% annually.

Using the formula:

Future Value = $50,000 × [(1 + 0.05)^25 - 1] / 0.05

= $50,000 × [2.128 - 1] / 0.05

= $50,000 × 2.256

= $112,800

This means you would need to save $112,800 today to have $50,000 per year for 25 years in retirement, assuming a 5% annual return.
