The pitch happens at the register, after you’ve already decided to buy. The salesperson asks if you want to add the protection plan, mentions that the manufacturer warranty is “only” a year, and walks you through the catastrophic scenarios you’d want to be covered for. It’s effective. Extended warranties are one of the most reliable revenue streams in retail.
The reason they’re so profitable is the same reason they’re a bad deal for you. The math has been worked out carefully, and not in your favor.
The numbers that retailers don’t share
Industry estimates put gross margins on extended warranties at 50% to 70%. Best Buy and other big-box retailers have publicly disclosed that protection plans are among their highest-margin products. Some categories, like furniture warranties, have margins above 80%. The reason is straightforward: most warranties are never claimed, and the ones that are claimed often face restrictions that limit payouts.
Consumer Reports has tracked extended warranty value for decades, and the conclusion has been remarkably consistent. For most product categories, the average warranty buyer pays substantially more in premiums than they ever get back in repairs or replacements. The exceptions exist (we’ll get to those), but the default assumption should be that the plan is bad value.
Why your existing protections are usually enough
Most credit cards extend manufacturer warranties by an additional year automatically when you use the card to make the purchase. Many high-end cards add purchase protection against theft and damage for 90 to 120 days. American Express still offers some of the best of these benefits, but Visa and Mastercard premium cards are competitive.
Layer that on top of state lemon laws, federal warranty regulations, and the basic fact that most products either fail in the manufacturer warranty period or last well beyond it, and the window where an extended warranty actually pays out is narrow. The bathtub curve of product failure rates means most things fail early (covered) or late (after the warranty would have expired anyway).
When warranties might make sense
There are a few categories where extended warranties have a defensible value proposition. High-end appliances with complex components, particularly refrigerators with ice makers and dishwashers with electronic controls, fail at higher-than-average rates between years two and five. Some manufacturer-direct extended warranties (not retailer plans) are priced more reasonably and have fewer claim hurdles.
Specific use cases also matter. If you’re hard on your phone and have a history of cracked screens, AppleCare+ might pay for itself. If you’re buying a luxury appliance from a small importer with a thin US service network, an extended warranty from the manufacturer can offer real continuity. The key is that the calculation has to be specific, not reflexive.
The takeaway
Extended warranties are profit centers disguised as peace of mind. Retailers push them because the unit economics are spectacular for the seller and mediocre for the buyer. Decline by default, check what your credit card already offers, and self-insure with the savings. If something fails outside the manufacturer warranty, repair costs are usually lower than a decade of declined plans.
