How Much Does It Cost to Run a Warming Tray?
Formula: `Watts x duty x hours / 1000 x $/kWh = cost`
At $0.15/kWh:
| Usage | kWh per Day | Cost per Day @ $0.15 | Cost per Month @ $0.15 | Cost per Month @ $0.30 |
|---|---|---|---|---|
| 2 hrs/day | 0.500 kWh | $0.075 | $2.25 | $4.50 |
| 4 hrs/day | 1.000 kWh | $0.150 | $4.50 | $9.00 |
| 8 hrs/day | 2.000 kWh | $0.300 | $9.00 | $18.00 |
| 24 hrs/day @ 50% | 6.000 kWh | $0.900 | $27.00 | $54.00 |
At California $0.45/kWh, 8 hours a day costs $27.00 per month.
