How the Calculator Works (Simple Explanation)
This tool uses two main financial principles:
1. Investment Growth (TSP Projection)
Your TSP balance grows based on:
- Compound interest
- Monthly contributions
- Time in the market
2. 4% Withdrawal Rule
This rule estimates sustainable retirement income:
- You can withdraw about 4% annually from your savings
- The calculator converts this into monthly income
3. FERS Pension Estimation
The pension is calculated using:
- High-3 salary × years of service × 1%
This provides a basic estimate of monthly retirement income.
