The Formula Explained

The retirement savings calculator uses the future value of an annuity formula to estimate your retirement savings. The formula takes into account your current savings, annual contributions, investment return rate, and the number of years until retirement.

Future Value of Annuity Formula

Future Value = (Current Savings × (1 + r)^n) + (Annual Contribution × [(1 + r)^n - 1] / r)

Where:

Current Savings = Your current retirement savings amount
Annual Contribution = Your expected annual contribution to retirement savings
r = Expected annual return rate (as a decimal)
n = Number of years until retirement (Retirement Age - Current Age)

This formula helps you understand how your current savings and future contributions will grow over time with compounding returns.

Worked Example

Let's walk through an example to demonstrate how the calculator works. Suppose you have the following details:

Current Savings: $50,000
Annual Contribution: $10,000
Current Age: 35
Retirement Age: 65
Expected Annual Return: 7%

Using these values, let's calculate your estimated retirement savings:

Calculate the number of years until retirement: 65 - 35 = 30 years
Convert the annual return rate to a decimal: 7% = 0.07
Calculate the future value of your current savings: $50,000 × (1 + 0.07)^30 ≈ $50,000 × 5.75 ≈ $287,500
Calculate the future value of your annual contributions: $10,000 × [(1 + 0.07)^30 - 1] / 0.07 ≈ $10,000 × [5.75 - 1] / 0.07 ≈ $10,000 × 7.57 ≈ $75,700
Add the two amounts together: $287,500 + $75,700 = $363,200

Based on these calculations, you would need approximately $363,200 in retirement savings to achieve your goal.
