Why Use a 401(k) Loan Calculator?

Borrowing from your retirement account has both benefits and risks. A calculator like this helps you:

Pro Tips for Using a 401(k) Loan Responsibly

• Borrow only what you need to minimize interest and risk to your retirement savings.
• Choose the shortest loan term you can afford—faster repayment means lower interest.
• Avoid missed payments to prevent tax penalties or early withdrawal fees.

• Funding home repairs or improvements when other financing options are limited.
