  • Starting in January 2021, we’re making the process easier for participants. If you’re turning 50 or older and are eligible for catch-up, you’ll no longer need to make separate catch-up elections to your TSP account. To learn how to make these contributions next year, visit Catch-up contributions.

The Loan Calculator estimates loan payments based on the amount you want to borrow from your TSP account, the current loan interest rate, and other factors. To borrow from your TSP account, you must be a Federal employee in pay status. If you qualify for a TSP loan, the maximum amount you may be eligible to borrow is $50,000; the minimum amount is $1,000. To find out the amount you have available to borrow, visit TSP Loans in the My Account section.

  • People often use this calculator to figure out a new dollar amount they should contribute to reach the IRS limit without going over. But when you change how much you’re contributing, it can take 1-2 pay periods for your agency or service to process the new amount. During that time, the TSP will still receive the amount you’re contributing now.

    Enter an estimate of how much you’ll contribute before any changes take effect. If you are uncertain, check with your personnel or finance office.

  • Enter a whole dollar amount between $1,000 and $50,000.

Interest Rate: The current rate for new loans is not available, which is the current G Fund interest rate.

Select the type of loan you wish to apply for:

  • There are two types of loans.

    • General purpose loan with a repayment period of 1 to 5 years. No documentation is required.
    • Residential loan with a repayment period of 1 to 15 years. Documentation is required.

    A residential loan can be used only for the purchase or construction of a primary residence. The residence can be a house, condominium, shares in a cooperative housing corporation, a townhouse, boat, mobile home, or recreational vehicle, but it must be used as your primary residence. The residence must be purchased (in whole or in part) by you or your spouse. You can obtain a residential loan for constructing a new residence or purchasing an existing residence. You cannot use a residential loan for refinancing or prepaying an existing mortgage, for renovations or repairs, for buying out another person’s share in your current residence, or for the purchase of land only.

    You may have only one general purpose loan and one residential loan outstanding at any one time. This is a per-account limit. If you have both a civilian account and a uniformed services account, you may have one of each type of loan for each account.

DISCLAIMER: This calculator is provided for informational purposes only. It is not intended to be used as an investment advisory tool or as a guarantee of a final account balance. Please note that the results shown at the end of this calculator assume that elected contributions are made for the entire year. Results do not take into account the following Internal Revenue Code (IRC) limits: elective deferral, section 415(c), and catch-up contribution. These limits, which may change every year, determine the maximum annual amount that you and/or your employing agency can contribute to the TSP on your behalf. You can view the current year’s limits on the TSP website under News and resources.
