Is 0% Financing Worth It? When to Take the Rate and When to Take the Rebate
Financing · 0% vs. the RebateIs 0% financing worth it? When to take the rate and when to take the rebate
Quick answer 0% financing is worth it when the interest it saves is larger than the cash you give up to get it, and that comes down to three numbers: how much GM cash is on the table, what rate you could get elsewhere, and how long you’ll actually keep the loan. On a 2026 Silverado with $3,750 of cash, 0% for 60 months beats the cash unless your credit union is under about 3.6%. On a 5.3L with $6,000 of cash, the cash beats 0% unless your other rate is above about 5.1%. Plan to pay it off in the first couple of years, or pay cash outright, and the rebate wins. We run both routes on your truck and show you the sheet.
Why 0% means giving up the rebate
A manufacturer’s 0% offer is a rebate paid as interest instead of cash. GM pays its own finance company to carry your loan at no interest, and it pays for that by not cutting the price. So the program is written as either/or: take the special rate, or take the customer cash and bonus cash. On a $43,000 truck, 0% for 60 months instead of a 6% loan is worth about $7,000 of interest over five years; the cash alternative on the same truck is $3,750. GM sizes the two to land close, then lets you choose. Which one is actually better for you depends on things GM can’t see: your credit union’s rate, your down payment, and how long you keep the loan.
The three numbers that decide it
1. How much cash you’re giving up
It changes by engine and trim, not just by model. In November 2026 a 2.7L Silverado gives up $3,750; a 6.2L gives up $3,250; a 5.3L gives up $6,000. The more cash, the harder 0% has to work to beat it.
2. The rate you can get without GM
Your credit union, your bank, or GM Financial’s own tiered rate (1.9% to 5.9% on the Silverado this month, which pairs with the cash). At 4% the cash usually wins. At 8% the 0% usually wins. We submit one application to all of them so you know your real number.
3. How long you’ll keep the loan
0% saves interest a month at a time; the cash is yours on day one. If you’re going to pay the truck off early, the 0% may not be worth taking: on the 2.7L example, a 6% credit-union loan on the cash route has only cost about $3,950 in interest by month 24, so a payoff before then is a wash or better with the cash in hand. At 4% that crossover moves out to month 42. Paying cash for the truck outright is the extreme case: take the rebate, there’s no loan to subsidize.
And one thing that doesn’t change: the price
At Carter the listed price is the price on either route, with no doc fee and no addendum. If a dealer’s 0% deal comes with a higher price, a fee or a “protection package,” the math on this page doesn’t apply; the rebate is being taken back somewhere else.
The math, on real trucks
Three Silverados, five ways to finance each. The 0% and 2.9% are GM Financial’s November 2026 offers for top credit tiers. The “take the cash” rows use 6% and 8% as stand-ins for a credit-union or bank rate; your number may be lower or higher. Payments assume $0 down and exclude tax, title and license.

Illustrative price; the 5.3L V8 carries the most cash in the November program ($4,250 customer + $1,750 bonus), which is why the cash route wins here.
Read across the “total paid” column. In Example 1 the 0% route is the cheapest unless the cash route’s rate is under 3.6%. In Example 2, with a bigger loan and less cash, the 0% wins by more; the break-even is 2.2%. In Example 3 the $6,000 of cash flips it: the cash route wins at 6% and only loses at about 5.1% or above. Same program, three different answers, which is why we don’t have a blanket rule.
When 0% is the right call
- The cash on your trim is small. 6.2L and Duramax Silverados, and most 2.7L trucks, carry $3,250 to $3,750 this month. That’s less than five years of interest at almost any real rate.
- Your other rate is 6% or higher. If the credit union comes back at 6.5% and you’re keeping the truck, 0% wins on the first and every other example above.
- You want the full 60 months and a buffer in the bank. With 0% you finance the whole price, which keeps your down payment in your checking account at no cost. There’s no cheaper money anywhere.
- You qualify. GM Financial’s top two tiers. If you’re not there, the choice is already made for you: the cash plus tiered rate support.
When the rebate is the right call
- The cash is large. The 5.3L V8 Silverado’s $6,000 this month, or $7,000 with the $1,000 trade assistance, is more than the interest on a 60-month loan at anything under about 5.1%.
- You have a low rate waiting. Oklahoma credit unions regularly beat 5% for strong credit. At 4% on a $44,000 loan the interest over 60 months is about $4,200; the cash is $3,750.
- You’ll pay it off early. The cash is realized on day one; the 0% is realized a month at a time. On the 2.7L example at a 6% alternative rate, the cash route is ahead until about month 23, and at 4% until about month 42. If a bonus, a sale, or a tax refund is going to clear the loan in the first couple of years, take the cash. Paying cash outright is the clearest case of all: take the rebate.
- You want the option to refinance. Take the cash now, refinance if rates fall later. You can’t refinance below 0%, so that route has nowhere to go.
- Your credit is mid-tier. You weren’t going to get the 0% anyway, and the cash pairs with GM Financial’s 1.9% to 5.9% tiered rates or a credit-union loan.

Frequently asked questions
Is 0% financing worth it?
Only when the interest it saves is bigger than the rebate you give up. Run the two totals: price financed at 0% versus (price minus the cash) financed at the rate you can actually get. On a 2026 Silverado with $3,750 of GM cash, 0% for 60 months wins unless your credit union is under about 3.6%. With $6,000 of cash on a 5.3L, the cash wins unless your other rate is above about 5.1%. The bigger the rebate and the lower your other rate, the worse 0% looks.
Why do you have to give up the rebate to get 0%?
Because the 0% is the rebate, paid a different way. GM subsidizes the loan instead of cutting the price. On a $43,000 truck, 0% for 60 months versus 6% is worth about $7,000 in interest; the cash alternative on the same truck is $3,750. GM sizes the two so they’re close, then lets you pick. Taking both would be getting the subsidy twice.
Does 0% financing hurt your credit?
No more than any other car loan. It’s a normal installment loan through GM Financial; the inquiry and the new account report the same way. What is different is the credit it takes to get it: 0% is reserved for GM Financial’s top tiers, so a buyer with a mid-600s score usually isn’t offered it and should run the cash route instead.
Is 0% for 60 months better than 2.9% for 75?
0% costs less; 2.9% for 75 has the lower payment. On a $43,474 truck, 0% for 60 is $725 a month with no interest; 2.9% for 75 is $634 a month with about $4,100 of interest. If the lower payment is what gets the truck into the budget, 2.9% is the right call; if you can carry the higher payment, 0% is cheaper by that interest.
Should I take 0% if I plan to pay the truck off early?
Usually not. The 0% only saves you interest while the loan is open, so the sooner you pay it off, the less it was worth. On a $43,474 2.7L Silverado with $3,750 of cash, a 6% credit-union loan on the cash route has cost about $3,950 in interest by month 24 and $5,250 by month 36, so a payoff inside the first two years is a wash or a win for the cash; at a 4% rate the cash stays ahead until about month 42. If you’re paying for the truck outright, take the rebate: there’s no interest for the 0% to save.
Can I take the 0% and then refinance?
You can, but there’s nothing to gain: you can’t refinance below 0%. The reverse is the move people miss: take the cash, finance at a credit-union rate, and refinance later if rates fall. The cash is locked in; the rate isn’t.
Does the 0% change the price of the truck?
Not at Carter. The listed price is the price whether you take 0%, take the cash, pay cash or bring your own bank. Some dealers quietly price a vehicle higher when you take the special rate, or add a doc fee or addendum that eats the rebate; that’s the thing to watch for anywhere a deal looks too clean. Our price is on the listing and there’s no doc fee or addendum behind it.
