Should You Defer a Car Payment? What a Skipped Month Really Costs

9 min read · Updated October 2026 · Written by AutoCalcHub Team

When money is tight, a lender's offer to let you skip a payment or two can feel like a lifeline. Sometimes it is. But a deferment is not a pause button — it's a small loan on top of your loan, and how much it costs depends heavily on your interest rate.

Quick answer: On most auto loans interest keeps accruing while you skip, and your next payments go to that interest before the balance. Two skipped payments on a $20,000 loan at 9% cost about $429 in total and push the payoff back three months. On a $15,000 loan at 25%, the same two months cost about $2,550 to $2,760. Defer for a short, known gap — never instead of fixing a payment that's too high every month. For that, look at refinancing or selling.

How a Deferment Actually Works

Nearly all US auto loans use simple interest, calculated daily on the outstanding balance. A deferment stops your payments for one to three months, but it doesn't stop the interest. Experian notes that interest accrues for the whole deferment period and that skipped payments are added to the end of the loan, not forgiven.

When payments restart, each one is applied to the built-up interest first. Your principal is therefore higher than it would have been for the rest of the loan, so you pay more interest overall — on top of the interest that accumulated during the skip.

What It Costs at Different Rates

Loan	Skipped	Interest during the skip	Total extra cost
$12,000 at 18%, 36 months left	1	$180	~$308
$20,000 at 9%, 48 months left	2	$300	~$429
$32,000 at 7.2%, 60 months left	3	$576	~$825
$15,000 at 25%, 72 months left	2	$625	~$2,758

Fees, where lenders charge them, typically add $25 to $75 on top. The last row is the warning: on high-rate subprime loans, a short deferment can cost several times the interest of the skipped months, because the high rate keeps compounding the effect of a slower-shrinking balance for years.

The Balloon Trap

Lenders handle the aftermath in one of two ways. Most extend the loan by the skipped months, so you keep paying the same amount for longer. Some keep the original end date instead, and whatever hasn't been covered becomes a lump sum due with the final payment.

ProPublica's reporting on subprime auto lenders found borrowers who had taken repeated extensions facing balloon balances of thousands of dollars years later. Its illustration — a $15,000 loan at 25% over 72 months with two deferments — ended with a final payment around $2,589. Our own calculation of the same loan, with both deferments at the start, gives about $2,546. Ask which method your lender uses before you agree, and get it in writing.

When Deferring Is the Right Call

The gap is short and has an end date: a new job starting next month, a one-off medical bill, a delayed paycheck.
The alternative is missing a payment. An approved deferment isn't reported as late. A payment you simply don't make is, and a 30-day late mark can raise the rate on your next loan by far more than the deferment costs.
Your rate is low. At 4% to 7%, one or two skipped months add relatively little.

Critically, don't stop paying until the lender has confirmed the deferment. Skipping before approval is a missed payment.

When It Isn't

The payment is too high every month, not just this month. A deferment only moves the problem — and makes it slightly bigger.
You've already deferred before. Repeated deferments are exactly the pattern that produces large balloon balances.
Your rate is high. Above 15%, deferments get expensive quickly.

The Alternatives Worth Checking First

Refinance. If your credit has improved, rates have fallen, or the dealer marked up your original rate, a refinance can lower the payment permanently — sometimes while also lowering total interest. A longer term lowers the payment further but usually costs more interest overall.
Ask about a due-date change. If the problem is timing rather than amount, moving the due date closer to payday can solve it for free.
Sell the car. If the car itself is unaffordable, selling it — even at a small loss — is almost always better than letting it reach repossession or a voluntary surrender.
