Retirement Savings Calculator
Calculate retirement savings based on annual salary, savings rate, and portfolio return assumptions.
Calculator Variables
Calculation Overview
Model your future retirement nest egg size using salary projections, savings rate percentages, and expected compound growth rates.
Mathematical Model & Formula
Determines the yearly cash flows saved based on your savings rate, and compounds that series alongside your initial retirement balance up to the age-67 retirement milestone.
- Annual Salary: Your current gross yearly income
- SavingsRatePercent: The percentage of your salary saved for retirement (decimal)
Worked Example Scenario
Scenario: A 25-year-old earning $50,000, saving 10% ($5,000/year) with a $5,000 initial balance, growing at 8% compound interest for 42 years (to age 67).
- Yearly contribution = $50,000 * 0.10 = $5,000
- Compound initial balance over 42 years: $5,000 * (1.08)^42 ≈ $126,675
- Annuity accumulation of $5,000/yr: $5,000 * [((1.08)^42 - 1) / 0.08] ≈ $1,520,892
- Add both values: $126,675 + $1,520,892 ≈ $1,647,567
Result: Retirement balance at age 67 is $1,647,567.
