TSP Loan Calculator

The TSP Loan Calculator is a financial planning tool designed specifically for federal employees and members of the uniformed services who participate in the Thrift Savings Plan (TSP). This calculator helps you estimate your loan payments, interest costs, and repayment schedule when borrowing from your TSP retirement account—ensuring you fully understand the short- and long-term impacts on your retirement savings.

What is a TSP Loan?

A TSP Loan allows eligible participants to borrow from their own TSP account. These loans are not issued by a bank or lender—instead, you’re borrowing from yourself, and your repayments (plus interest) go back into your TSP account. There are two main types:

  • General Purpose Loan: For any use, with a repayment term of 1 to 5 years.
  • Residential Loan: For purchasing or building a primary residence, with a repayment term of 1 to 15 years.

While the interest rate is relatively low (tied to the G Fund), borrowing from your TSP can affect your retirement growth, so planning ahead is crucial.

Why Use the TSP Loan Calculator?

This calculator helps you:

  • Estimate your monthly loan payments
  • See the total interest you’ll repay
  • Understand the repayment timeline
  • Evaluate how the loan might impact your future retirement balance
  • Compare different loan terms and amounts

By modeling different scenarios, you can determine whether a TSP loan is a financially wise decision for your current needs and long-term goals.
