Warranty Expiry Calculator
Enter your purchase date and warranty length to find the estimated expiry date.
Estimated warranty expiry
Save this date and your receipt in the Return & Refund Tracker app so you have everything ready if you need to make a claim.
This is an estimate. The calculator uses the purchase date and warranty length you enter. Always refer to the actual warranty documentation that came with your product for the exact terms and start date.
How warranty expiry is worked out
Most manufacturer warranties last a set number of months or years from the purchase date on your receipt. A one-year warranty on a vacuum bought on March 15, 2026 runs until March 15, 2027. The calculator adds the warranty length to the date you enter.
Some warranties don’t follow that simple rule:
- Delivery date starts. Some brands count from delivery for online orders, or from whichever date is later.
- Different terms for different parts. Appliances often cover parts and labor for one year and specific components (like a compressor or motor) for longer.
- Credit card extensions. Many cards add time to an eligible manufacturer warranty if you paid with that card. The extension starts when the manufacturer’s coverage ends.
- Store and paid plans. Costco, for example, extends the manufacturer’s warranty to two years on TVs, computers, and major appliances. Paid protection plans have their own start dates and terms.
What you’ll need for a claim
Keep these together from the day you buy:
- The receipt or order confirmation showing the date, store, and item
- The model and serial number, from the label on the product or the box
- The warranty terms that came with it, or a link to them
- The registration confirmation, if you registered it
The date on the receipt matters most. Manufacturers use it to decide whether you’re covered, and a claim without it is easy to deny. Read what counts as proof of purchase if your receipt is missing or faded.
Common reasons warranty claims fail
- No dated proof of purchase. Photograph receipts for anything with a warranty.
- The warranty ran out a few weeks ago. Note the end date when you buy.
- The damage looks accidental. Drops, spills, and cracked screens are usually excluded. Say what happened and when the fault started.
- The product was shipped before the claim was opened. Get a claim or case number first and follow the manufacturer’s shipping instructions.

Common questions
Does a warranty start on the purchase date or when I start using the product?
Almost always on the purchase date shown on the receipt, or the delivery date for some online orders. Dyson, for example, counts from the purchase or delivery date, whichever is later. If you can't prove the purchase date, a manufacturer may fall back on the manufacturing date, which shortens your coverage.
Does a warranty transfer if I buy something used?
It depends on the brand. Some warranties cover only the original buyer; others transfer with the product as long as you can show the original purchase date. Check the warranty terms before you buy secondhand if the coverage matters.
Do I have to register a product for the warranty to count?
Usually not. Registration records your purchase date and can speed up a claim, and many brands say skipping it doesn't reduce your rights. Read your product's warranty terms to be sure.
What if I can't find the receipt?
Try the store first. Many can reprint a receipt from the card you paid with or your account, and online orders are in your order history. Some manufacturers can also check coverage from the serial number alone.
