## About
A cheap older device can cost more per useful year than a newer one if its security updates end soon. Enter the price you would pay, what you expect to sell it for and the date the maker says support ends. Always check the support date on the manufacturer's own site because it changes.

## FAQ
**Why use cost per supported year?** It prices a device by how long it stays safe to use, not just by sticker price. A £150 phone with one year of updates can cost more per year than a £450 phone with six.

**Is the Used Gadget Support-Life Calculator free?** Yes, with no sign-up or limits.
