Formula Used in the Calculator
This calculator is based on simple financial formulas that convert your retirement savings into income estimates.
1. Annual Withdrawal
Annual Withdrawal = (Account Balance × Withdrawal % ) ÷ 100
2. Monthly Withdrawal
Monthly Withdrawal = Annual Withdrawal ÷ 12
3. Tax Amount
Tax Amount = (Annual Withdrawal × Tax Rate) ÷ 100
4. Net Annual Withdrawal
Net Withdrawal = Annual Withdrawal − Tax Amount
These formulas help you understand both gross and net retirement income clearly.
Example Calculation
Let’s understand how the calculator works with a real-life example.
Assumptions:
- 403(b) Balance: $200,000
- Withdrawal Rate: 4%
- Tax Rate: 20%
Step-by-step Calculation:
- Annual Withdrawal = 200,000 × 4% = $8,000
- Monthly Withdrawal = 8,000 ÷ 12 = $666.67
- Tax Amount = 8,000 × 20% = $1,600
- Net Annual Withdrawal = 8,000 − 1,600 = $6,400
Results Summary Table
| Description | Amount (USD) |

Understanding Withdrawal Percentage
Choosing the right withdrawal percentage is critical for long-term financial stability.
Common Withdrawal Rates:
- 3% – Conservative: Best for long retirement periods
- 4% – Standard Rule: Balanced approach for most retirees
- 5% – Moderate: Higher income but faster depletion risk
- 6%+ – Aggressive: Higher risk of running out early
The famous “4% rule” is widely used as a safe withdrawal guideline for retirement planning.
