Click "Calculate" to see your results

The calculator will show you how much you need to save today to achieve your retirement goals, along with a projection of your savings growth over time.

Formula Used

The amount of money needed to retire is calculated using the future value formula for compound interest:

Future Value = P × (1 + r)^n

Where:

P = Desired annual retirement income
r = Expected annual return on investment (as a decimal)
n = Number of years until retirement

To find the present value (amount needed to save today), we rearrange the formula:

Present Value = P × (1 + r)^-n

This formula assumes you'll withdraw your desired annual retirement income each year from your savings account, earning the same annual return on investment.

Worked Example

Let's say you're 35 years old and plan to retire at 65, with 30 years until retirement. You currently save $20,000 per year and expect a 7% annual return on your investments. You want to withdraw $50,000 per year in retirement.

Using the formula:

Present Value = $50,000 × (1 + 0.07)^-30

Present Value ≈ $50,000 × 0.0606

Present Value ≈ $3,030

This means you would need to save approximately $3,030 today to achieve your retirement goals, assuming you contribute $20,000 per year to your retirement account.
