Extended Warranty Calculator
Enter the product price, the extended warranty cost, what an out-of-pocket repair would run, and honest failure odds for years 2 to 4. The calculator compares the plan against the expected repair cost and gives a plain verdict.
Warranty desks exist because the plans are profitable, not generous. The math here shows what odds the plan needs to be worth it - usually far above reality - and covers the two outs people forget: free warranty doubling through many credit cards, and the self-insurance drawer that funds the one failure you actually have.
How to use
- Get the real plan price at the register, not the brochure estimate.
- Estimate the repair cost honestly - a screen or a logic board, not goodwill.
- Pick failure odds; most electronics sit near 10 percent in years 2-4.
Frequently asked questions
Are extended warranties worth the money?
Usually not on the math: plans are priced with fat margins, so the failure odds needed to justify them run several times reality for most electronics. Exceptions exist - fragile screen-first devices, repair costs close to replacement, or a plan that also covers accident damage you genuinely expect.
Does my credit card cover warranty already?
Many cards extend the manufacturer warranty by up to a year for free - the benefit is printed on the card guide. That alone often covers the most likely early-failure window and makes the retail plan redundant before the pitch starts.
What is self-insuring against repairs?
Skipping every plan and setting its price aside instead. Across a few gadgets the jar grows faster than the failures arrive, and unspent jar money stays yours - the opposite of a plan, where unused premiums are pure margin.
What failure rate makes a warranty worth it?
The warranty cost divided by the repair cost - that is the break-even odds figure in the calculator. If a 120 dollar plan covers a 300 dollar repair, it pays at 40 percent failure odds; real-world rates sit far below, which is the whole business model.
