Personal loan vs borrowing from family.
Family loans are usually the cheapest pre-tax option (the IRS Applicable Federal Rate runs well below market personal-loan APRs) and the most expensive emotional one. Personal loans cost more in dollars but cost nothing in the relationship. The right answer depends on the size of the loan, the durability of the relationship, and how disciplined both sides are about treating the arrangement as a loan rather than a gift.
Personal loan vs Family loan
| Attribute | Personal loan | Family loan |
|---|---|---|
| Interest rate | 5.99% to 35.99% | 0% to AFR (currently 4 to 5% short-term, 4 to 5% mid-term) |
| Underwriting | Credit + income + DTI checks | None (or whatever the family agrees to) |
| Time to fund | Next business day | As fast as the family member transfers it |
| Documentation | Loan agreement, promissory note, TILA disclosures | Should be a written promissory note (often skipped, often regretted) |
| Credit-bureau reporting | Yes, builds credit history | No, neutral effect on credit |
| Default consequences | Credit damage, collections, possible lawsuit | Relationship damage, family-event tension, possible lawsuit if formalised |
| Tax consequences | Borrower: none. Lender: none. | Loans over $10,000 below AFR can trigger 'imputed interest' rules; gifts over annual exclusion ($18,000 in 2026) trigger gift-tax reporting |
| Best for | Most borrowers, especially when the alternative is asking family | Large amounts ($25k+) between disciplined relatives with documentation |
Which wins, when.
- 01
$3,000 to consolidate cards, multiple relatives offering
Winner: Personal loan
Save the relationship. Personal-loan total cost at this size is small; the optionality of paying a stranger has real value.
- 02
$50,000 down payment from parents at AFR, written note, both sides disciplined
Winner: Family loan
The dollar savings vs a personal loan are real and the family is documenting properly. Best-case use of a family loan.
- 03
You have missed payments to family in the past
Winner: Personal loan
Past behaviour predicts future behaviour. If a family loan is likely to default, do not start a second cycle of relationship damage.
- 04
Family member has the cash but expects you to pay back with interest
Winner: Personal loan
If interest is going to be charged anyway, paying it to a third party preserves the family relationship and builds the borrower's credit history at the same time.
Frequently asked.
What is the IRS Applicable Federal Rate (AFR)?+
The AFR is the minimum interest rate the IRS requires on private loans to avoid the loan being treated as a partial gift. Three tiers: short-term (under 3 years), mid-term (3 to 9 years), and long-term (over 9 years). The IRS publishes the rates monthly. As of mid-2026, AFRs are roughly 4 to 5% across tiers.
Do I need to charge interest on a family loan?+
Not strictly. Loans under $10,000 can be interest-free with no tax consequences. Loans of $10,000 to $100,000 below AFR trigger 'imputed interest' rules where the IRS treats the foregone interest as taxable income to the lender, even if no money changed hands. Loans over $100,000 are stricter still. Charge at least AFR to avoid the headache.
Should we put it in writing?+
Yes, always. A simple promissory note with the principal, interest rate, payment schedule, and default terms protects both sides. It also makes the arrangement feel real, which improves repayment discipline. Templates from LegalZoom or Rocket Lawyer cost under $50.
What if the family member dies before I repay?+
The loan becomes an asset of the lender's estate. The executor must collect from the borrower as part of probate. This is a common reason to formalise the loan: an undocumented family loan can become a contested estate matter, where heirs disagree about whether it was a loan or a gift.
