Warranty expiry calculator

Enter when you bought it and how long the warranty lasts. We'll tell you the exact expiry date and how long you have left to claim.

Why warranty dates slip through the cracks

Warranties are easy to forget — the receipt goes in a drawer and the expiry date is nowhere. But a broken appliance that's still under warranty can be repaired or replaced for free, so knowing the date is worth real money. This calculator gives you the exact end date; save it somewhere you'll actually see it.
