About this tool

Taking a loan from your 401(k) might seem like an easy way to access cash, but it comes with hidden long-term costs. While you are technically paying yourself back with interest, the money you withdrew is no longer growing in the market. This free 401(k) Loan Calculator helps you evaluate the true cost of borrowing from your future. By entering your loan amount, interest rate, and repayment term, you can instantly estimate your monthly payments and total interest. More importantly, this tool helps you understand the "opportunity cost"—the potential investment earnings you miss out on while the money is out of your retirement account. Use this calculator to weigh the pros and cons carefully, ensure you can afford the repayments, and protect your hard-earned retirement nest egg before making a withdrawal.
