What Is a TSP Loan?
A Thrift Savings Plan (TSP) loan allows participants to borrow money from their own retirement savings. Unlike other loans, TSP loans offer:
- Low interest rates
- No credit check
- Direct repayment through payroll deductions
There are typically two types of TSP loans:
- General Purpose Loan: Can be used for any personal needs and must be repaid within 5 years.
- Residential Loan: Can be used to buy or build a primary residence and has a repayment term of up to 15 years.
Borrowing from your TSP should be carefully considered, as it affects your retirement savings growth.
How the TSP Loan Calculator Works
Our calculator uses a simple formula to compute your monthly payments:Monthly Payment=1−(1+r)−nP×r
Where:
- P = Loan amount
- r = Monthly interest rate (annual rate ÷ 12)
- n = Total number of payments (months)
By entering your loan amount, interest rate, and loan duration, the calculator instantly displays your monthly repayment amount and total repayment. This saves you time and eliminates manual calculations.
How To Use the TSP Loan Calculator
Using the calculator is straightforward. Follow these steps:
Step 1: Enter the Loan Amount
Input the total amount you want to borrow from your TSP account. Example: $10,000.
Step 2: Enter the Annual Interest Rate (%)
Provide the TSP loan interest rate. TSP rates are set quarterly and are usually slightly above the G Fund rate. Example: 5%.
Step 3: Enter the Loan Term
Specify the number of years you plan to repay the loan. For general purpose loans, the maximum is 5 years. For residential loans, it can go up to 15 years.
Step 4: Click “Calculate”
The calculator instantly shows:
- Monthly Payment – Amount deducted from your paycheck each month
- Total Payment – Total amount repaid over the loan term
- Interest Paid – Total interest cost for the loan
Step 5: Reset (Optional)
Click the reset button to clear all fields and perform a new calculation.
Example TSP Loan Calculation
Suppose you take a $15,000 general purpose TSP loan at 5% interest to be repaid over 5 years.
- Loan amount: $15,000
- Annual interest rate: 5%
- Loan term: 5 years
The calculator computes:
- Monthly Payment: ~$283
- Total Payment: ~$16,980
- Interest Paid: ~$1,980
This allows you to plan your budget efficiently and ensure that repayments are manageable alongside your other expenses.

Tips for Using TSP Loans Wisely

TSP Loan Rules and Considerations
- Repayment via Payroll: Loan repayments are automatically deducted.
- Loan Type: Decide between general purpose and residential loan depending on your need.
