Frequently Asked Questions
How does a 401(k) calculator work?
A 401(k) calculator estimates your future balance by combining your contributions, employer match, compound growth, and taxes. It projects year-by-year savings until your retirement age.
How much should I contribute to my 401(k)?
Experts often recommend contributing at least enough to get the full employer match. Many people aim for 10–15% of their income, but the right number depends on your age, salary, and retirement goals. Use this calculator to test different contribution levels.
Can I calculate 401(k) growth with inflation?
Yes. Our calculator allows you to include an inflation-adjusted projection, so you can see the real purchasing power of your savings at retirement.
What’s the difference between Traditional and Roth 401(k)?
Traditional 401(k): Contributions are pre-tax, but withdrawals are taxed. Roth 401(k): Contributions are after-tax, but withdrawals in retirement are tax-free. Our tool includes both, acting as a 401(k tax savings calculator for comparison.
How accurate are 401(k) calculators?
They provide estimates, not guarantees. Actual results depend on investment returns, inflation, employer policies, and tax law changes (like Secure Act 2.0). Use it as a planning guide, not a prediction.
Formulas & Calculation Logic
1. Salary Progression
Salary(t) = Current Salary × (1 + Growth Rate)^(t-1)
2. Employee Contribution
Employee Contribution = Contribution Rate × Salary (capped at $23,000 for 2024)
3. Employer Match
If Employee Rate ≤ Match Limit: Match = Match Rate × Salary
Else: Match = Match Rate × (Match Limit × Salary)
4. Balance Growth
New Balance = (Previous Balance + Contributions) × (1 + Return Rate)
5. Early Withdrawal Penalty
Net Amount = Withdrawal × (1 - Penalty Rate) × (1 - Tax Rates)
