The calculator will display your future account value and provide a growth chart to visualize your savings over time.

Formula Used

The retirement account value is calculated using the future value of an annuity formula:

Future Value = Current Balance × (1 + Annual Return)^Investment Period + Annual Contribution × [(1 + Annual Return)^Investment Period - 1] / Annual Return

Where:

Current Balance - Your current retirement account balance
Annual Contribution - The amount you contribute to your account each year
Annual Return - The expected annual return on your investment (expressed as a decimal)
Investment Period - The number of years you plan to invest

This calculation assumes your contributions are made at the beginning of each year and that the annual return is compounded annually.

Worked Example

Let's say you have $50,000 in your retirement account, contribute $10,000 annually, expect a 7% annual return, and plan to invest for 20 years. Here's how the calculation works:

Future Value = $50,000 × (1 + 0.07)^20 + $10,000 × [(1 + 0.07)^20 - 1] / 0.07

Calculating each part:

$50,000 × (1.07)^20 ≈ $50,000 × 3.5274 ≈ $176,370
$10,000 × [(1.07)^20 - 1] / 0.07 ≈ $10,000 × [3.5274 - 1] / 0.07 ≈ $10,000 × 2.4619 ≈ $24,619

Adding these together gives a future value of approximately $201,000.

Interpreting Results

The calculated future value represents your retirement account's estimated worth after the specified investment period. Consider the following when interpreting your results:

Higher annual returns will significantly increase your future account value.
Longer investment periods provide more time for compounding to work.
Regular contributions compound over time, increasing your account value.
Market fluctuations and economic conditions may affect actual returns.
