Practical Example

Suppose you are 40 years old with the following TSP account details:

• Current Balance: $10,000
• Monthly Contribution: $500
• Annual Interest Rate: 6%
• Years Until Retirement: 20

The calculator projects:

• Total Contributions: $500 × 12 months × 20 years = $120,000

This example illustrates how consistent contributions and compound interest can significantly grow retirement savings over time.
