How It Works
The 401(k) Calculator uses several key calculations to project your retirement savings:
- Annual Contribution Calculation:
- Account Growth Calculation:
- Inflation Adjustment:
- Monthly Retirement Income:
Employee Contribution = Salary × Contribution Percentage Employer Contribution = Min(Salary × Match Limit, Employee Contribution) × Employer Match Percentage
Annual Growth = Previous Balance × (1 + Expected Return) New Balance = Annual Growth + Employee Contribution + Employer Contribution
Real Value = Nominal Value ÷ (1 + Inflation Rate)^Years
Monthly Income = Final Balance × (4% ÷ 12)
The calculator takes into account compound interest, employer matching, salary increases, and inflation to provide a comprehensive view of your retirement savings potential.
