Should I Borrow from My 401k? Decision Framework and Calculator

Should I Borrow from My 401k?

This is one of the most personal financial decisions you’ll make. There’s no one-size-fits-all answer, but there is a framework to help you decide.

The Decision Framework

Ask yourself these five questions in order:

1. Do I have stable employment?

• Yes → Continue to question 2
• No → Don’t borrow. A job loss turns your loan into a taxable distribution

2. Have I exhausted cheaper alternatives?

• Emergency fund, personal loans, HELOC, family loans
• Yes → Continue to question 3
• No → Use the cheaper option first

3. Is the 401k rate lower than my alternatives?

• 401k rate (~9.5%) vs personal loan rate (10-36%)
• Yes → Continue to question 4
• No → Use the cheaper option

4. Can I repay within 5 years?

• Include a buffer for unexpected expenses
• Yes → Continue to question 5
• No → Don’t borrow. Longer terms increase risk

5. Am I comfortable with the opportunity cost?

• Calculate missed investment growth using our calculator
• Yes → A 401k loan may be right for you
• No → Look for alternatives

Pros and Cons

Pros:

• No credit check required
• Interest goes back to your account
• Quick access to funds
• No impact on credit score
• Lower rates than many personal loans

Cons:

• Job change triggers repayment within 60 days
• Reduces your retirement savings growth
• Double taxation on interest (pay with after-tax, taxed again at withdrawal)
• Can’t contribute to 401k while loan is outstanding (some plans)
• Psychological cost of seeing a smaller retirement balance

Red Flags — Don’t Borrow If…

• You’re planning to change jobs within 5 years
• Your employer is planning layoffs
• You’re near retirement age
• You’re borrowing for discretionary spending
• You already have high-interest debt you can’t manage

Real Stories: When It Worked

Scenario 1: Medical emergency, stable job

• Borrowed $15,000 for surgery not covered by insurance
• Repaid in 3 years, stayed at same employer
• Total cost was lower than credit card interest would have been

Scenario 2: Home purchase, 15-year term

• Borrowed $50,000 for down payment on undervalued home
• Home appreciated $80,000 in 5 years, offsetting missed 401k growth
• Continued contributing to 401k alongside loan repayment
