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, click on "Loan Amount Available and Current Loan Interest Rate" in the Account Access section.
Before you apply for a loan, read the booklet TSP Loan Program for information about the TSP loan process (including the cost of a TSP loan) and about your obligations to repay the loan. The loan application (Form TSP-20 for civilians and Form TSP-U-20 for uniformed services) is also on this Web site.
