Formula Used
The retirement account calculator uses the future value of an annuity formula to estimate your savings growth:
Future Value of Annuity Formula
FV = P × [((1 + r)^n - 1) / r] × (1 + r)
Where:
- FV = Future Value of the annuity
- P = Annual payment (your annual savings)
- r = Annual interest rate (your expected annual return)
- n = Number of periods (years until retirement)
This formula calculates the future value of a series of regular payments (your annual savings) with compound interest.
Worked Example
Let's say you are 30 years old, plan to retire at 65, save $20,000 per year, and expect an 8% annual return on your investments.
Using the formula:
Example Calculation
FV = $20,000 × [((1 + 0.08)^35 - 1) / 0.08] × (1 + 0.08)
FV ≈ $20,000 × [((1.08)^35 - 1) / 0.08] × 1.08
FV ≈ $20,000 × [12.5 × 1.08] ≈ $20,000 × 13.56 ≈ $271,200
This means you could have approximately $271,200 saved for retirement at age 65.
