The calculator uses the future value of an annuity formula to estimate your retirement savings. You can adjust the inputs to see how different scenarios affect your retirement savings.

Formula Explained

The calculator uses the following formula to estimate your retirement savings:

Future Value of Annuity Formula

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

FV = Future Value (your retirement savings)
P = Current Savings
PMT = Annual Contribution
r = Expected Annual Return (as a decimal)
n = Years Until Retirement

This formula calculates the future value of your current savings plus the future value of a series of annual contributions, assuming a constant annual return.

Worked Example

Let's say you have $50,000 saved up, plan to contribute $10,000 annually, expect an 8% annual return, and have 20 years until retirement. Here's how the calculation works:

Example Calculation

FV = $50,000 × (1 + 0.08)²⁰ + $10,000 × [(1 + 0.08)²⁰ - 1] / 0.08

FV ≈ $50,000 × 5.74 + $10,000 × 11.48

FV ≈ $287,000 + $114,800

FV ≈ $401,800

In this example, you would have approximately $401,800 saved up when you retire.
