Personal Loan vs 401(k) Loan: How They Differ (2026)

A personal loan borrows from a lender — your retirement savings stay fully invested. A 401(k) loan borrows from your own retirement account balance, which you repay to yourself with interest; the borrowed funds stop compounding for the duration of the loan. Personal loans create a credit inquiry and appear on your credit report; 401(k) loans do not. The key risk of a 401(k) loan is job-change risk: if you leave or lose your job, the outstanding balance typically becomes due quickly — and an unpaid balance becomes a taxable distribution with a 10% early withdrawal penalty for borrowers under 59½.

If you leave your employer (voluntarily or involuntarily) with a 401(k) loan outstanding, most plans require full repayment by the date your federal tax return is due for the year of separation (including extensions). If you cannot repay, the outstanding balance is treated as a taxable distribution — added to your ordinary income for that year — and borrowers under age 59½ also owe a 10% early withdrawal penalty on the unpaid amount.

No. A 401(k) loan does not appear on your credit report and does not affect your FICO score. There is no hard inquiry, no tradeline, and no payment history reported to the credit bureaus — because you are borrowing from your own account, not from a lender. A personal loan, by contrast, involves a hard inquiry at application and creates a new installment tradeline on your credit report. Both the inquiry and the payment history affect your FICO score.
