Used vs new appliance: compare cost per year, not price
A used appliance has a lower price but a shorter remaining life and often no warranty. Cost per year shows which one is cheaper.
Worked example
| New | Used | |
|---|---|---|
| Price | $800 | $400 |
| Expected further use | 8 years | 3 years |
| Expected repairs (average) | $40 | $100 |
| Total | $840 | $500 |
| Cost per year | $105.00 | about $166.67 |
The used unit costs half as much but is more expensive per year because it will not last as long. If the used unit would give you 5 years, its cost per year falls to ($400 + $100) / 5 = $100, close to the new one. The estimate of remaining life is what decides the result.
Inspection checklist
- Age and how it was used
- Test it running: noise, leaks, smells, vibration
- Check that accessories and filters are included
- Ask for service records and any remaining warranty
- Confirm you can transport and install it
When new is better
For appliances that run many hours, a newer efficient model can save electricity. For appliances you rarely use, a used one is often a reasonable choice.
