Borrowing $400: the fee is not the real risk

Consumer regulators use $400 as their textbook payday loan example, and it fits: it's a dental bill, a brake job, a week of lost shift work. But the textbook example usually stops at the first fee. This page walks the full timeline — including what happens on day 15 if the repayment doesn't fit your paycheck — because that's where a $400 loan either stays cheap or gets genuinely expensive.

The base cost of $400

In states that allow single-payment payday loans, fees typically run $10–$30 per $100 borrowed {{VERIFY: fee range varies by state}}. At $15 per $100:

• You borrow $400 today.
• In two weeks you owe $460 — the $400 plus a $60 fee.
• As an annualized rate: $60 ÷ $400 = 15% over 14 days, × (365 ÷ 14) ≈ 391% APR.

If you repay $460 on the due date and move on, the loan cost you $60. Expensive per dollar, but contained. The product's real danger lives in what happens when $460 doesn't fit in that paycheck.

The rollover timeline, in plain numbers

Follow one loan through a rough month and a half:

• Day 1: Borrow $400. Owe $460 on day 15.
• Day 15: Paycheck arrives, but rent and groceries claim it. You pay the $60 fee to roll the loan. Total fees paid: $60. Still owe: $460.
• Day 29: Same squeeze. Another $60 rollover. Fees paid: $120. Still owe: $460.
• Day 43: One more. Fees paid: $180. Still owe: $460.

Six weeks in, you've paid $180 — nearly half the original loan — and your balance hasn't dropped a dollar. This isn't a rare failure mode; regulators have found that a large share of payday loans go to borrowers in long re-borrowing sequences {{VERIFY: CFPB reborrowing findings}}. Some states ban rollovers or require lenders to offer a no-cost extended payment plan {{VERIFY: state rollover rules}} — your state's rules are on our states page, and they're worth knowing before the due date, not after.

The one-question test before you borrow $400: subtract your fixed obligations from your next paycheck. If the remainder isn't at least $460 with room to eat, the single-payment structure is wrong for you — either borrow less, or use an installment structure with payments your check can actually absorb, even though the total cost runs higher. Our installment loan guide explains the trade.

Cheaper ways to solve a $400 problem

In order of typical cost:

1. Split the bill at the source. Dentists, mechanics, and hospitals frequently take half now, half later — turning a $400 problem into two $200 problems that an advance app or a lean week can cover for nearly nothing.
2. Earned wage access apps. Limits of $100–$300 are common, so an app may cover most of the gap, shrinking what you'd need to borrow at payday rates.
3. Credit union options. Payday Alternative Loans at federal credit unions run up to 28% APR — on $400 over three months, interest is under $20. You need to be a member, but joining is often a $5–$25 affair.
4. Local help. 211 routes you to programs that cover utilities, food, and sometimes emergency repairs, freeing up your own cash.

The full list is on our alternatives page. If none of it covers you, then compare actual loan offers — one request reaches multiple licensed lenders, and comparing beats taking the first yes. When offers arrive, ignore the marketing and read two lines: the total dollar amount due, and the exact date it's due. Those two lines are the entire deal.

Scenario: the cracked molar

A cracked tooth doesn't wait for payday. The dentist quotes $400 for the repair, and pain makes "save up for it" a non-answer.

The strong move: ask the office about a payment plan first — dental offices deal with this daily, and many split bills interest-free or work with financing that's far cheaper than payday rates. Say they take $200 up front. Now your borrowing need is $200, your advance app covers $150 of it, and you're bridging $50 — a problem a lean grocery week solves.

If the office wants it all now and no cheaper route works, a $400 loan repaid once costs about $60 at the common tier. Painful but bounded — and far better than letting the tooth turn into an $1,800 root canal. Sometimes the loan genuinely is the right call. The job is making sure it's the one-fee version, not the timeline above.

Bottom line

$400 borrowed and repaid on schedule: roughly a $60 problem. $400 rolled over for six weeks: a $180-and-counting problem with the debt still intact. The difference isn't luck — it's whether the repayment fit your paycheck before you signed. Do that math first, in writing. If the honest answer is that it doesn't fit, look at $500, where credit union alternatives get especially strong, or step down to $300 and split the rest.
