The protection plan offered at checkout usually duplicates coverage you already have. The manufacturer warranty handles year one, your credit card may quietly add a second year, and the plan itself often costs 15% to 25% of the item price for a repair you have a single-digit chance of needing. The exceptions are narrow but real, and they come down to whether the product has one expensive part that fails as a unit.

Key Takeaways
- Year one is almost always covered by the manufacturer, so a plan sold as "three years of protection" is often two years of new coverage.
- American Express adds up to one extra year on manufacturer warranties of five years or less; several Chase cards add a year on warranties of three years or less. Terms change, so read your card's benefits guide.
- If the plan costs more than 15% of the item price, the expected repair cost rarely justifies it.
- Plans make sense where one costly sealed component can fail: refrigerator compressors, laptop displays, treadmill motors.
- Standard plans exclude accidental damage. Drops and spills need a separate, more expensive tier.

Year One Is Almost Always Already Covered
Nearly every appliance, television and computer ships with a one-year manufacturer warranty against defects, and many large appliances carry longer coverage on specific components. A five-year sealed-system warranty on a refrigerator is common even when the overall warranty is one year.
So when a store sells a three-year plan, compare it against what you already hold. If the manufacturer covers year one and the compressor through year five, the plan is buying you two years of coverage on the parts least likely to fail expensively.
Check Your Card's Benefits Guide Before the Checkout Page
Extended warranty coverage through credit cards has thinned over the past decade, but it has not disappeared. As of 2026:
- American Express extends eligible manufacturer warranties of five years or less by up to one additional year on covered cards.
- Chase offers extended warranty on a range of Visa Signature cards, typically adding one year to manufacturer warranties of three years or less.
- Citi pulled the benefit from its Costco cards in January 2023, then added extended warranty coverage to the Citi Double Cash account from November 2024.
Coverage varies by specific card and issuers revise these terms with notice, so pull up your own guide to benefits rather than relying on what a card offered a few years ago. The document is normally available in your card account under benefits or card services.
The 15% Rule
A quick screen: divide the plan price by the item price. Above 15% and the math rarely works, because the probability of a covered failure inside the plan term multiplied by the repair cost usually lands below what you paid.
Worked example. A $700 washing machine with a $140 three-year plan is a 20% ratio. For that to break even, you would need roughly a one-in-five chance of a $700 repair in years two and three combined, which is well above observed failure rates for the category in that window.
The ratio flips on cheap plans for expensive items. A $60 plan on a $2,000 refrigerator is 3%, and a compressor replacement runs $500 to $1,200, so the expected value is much closer.
Where Plans Actually Pay Off
Three characteristics make coverage worth considering:
- One expensive sealed component. Refrigerator compressors, laptop displays, treadmill motors and dishwasher control boards fail as a unit and cost a large fraction of the item price to replace.
- Repair requires a technician visit. Anything plumbed or hardwired carries a $90 to $150 call-out fee before parts, which a plan absorbs.
- Heavy or daily use. A washer running eight loads a week is on a different failure curve from one running two.
Small electronics fail early or not at all, which is exactly the window the manufacturer already covers. That is why plans on $200 devices are the worst value on the shelf.

What Filing a Claim Actually Takes
Card-based coverage pays out reliably, but only if you kept the paperwork. Save these at purchase, not at failure:
- The itemized receipt showing the product and price
- The card statement line for the purchase
- The manufacturer's warranty document, usually a PDF on the support site
When something fails, get a repair estimate or a written denial from the manufacturer first, since card benefit administrators normally require proof the original warranty has expired or declined the claim. Filing windows are commonly 30 to 90 days from the failure date, so start the process the week it breaks rather than the month after.
Frequently Asked Questions
Are extended warranties worth buying?
Usually not. The 15% rule is a fast screen: if the plan costs more than 15% of the item price, the expected repair cost rarely justifies it. Plans make more sense on items with one expensive sealed point of failure.
Does my credit card extend the manufacturer warranty?
Many still do, though terms vary by issuer and card. American Express adds up to one extra year on manufacturer warranties of five years or less, and several Chase cards add a year on warranties of three years or less. Check your card's guide to benefits, since issuers revise these terms.
What does a warranty claim actually require?
Typically the itemized receipt, the card statement showing the purchase, the manufacturer warranty document, and a repair estimate or denial. Claim windows are often 30 to 90 days from the failure, so file early.
Does an extended warranty cover accidental damage?
Standard extended warranties cover mechanical and electrical failure only. Drops, spills and cracked screens require a separate accidental damage plan, which is why phone and laptop plans cost noticeably more.
