What outdoor & big-ticket appliances cost to run
Pool pumps, hot tubs, EV charging and mining rigs: the loads that can rival a whole household on their own. These are the ones worth modelling properly rather than guessing at.
| Appliance | Per month | Per year | On this assumption |
|---|---|---|---|
| Pool pump | $66.33 | $795 | 1,500W for 8 h a day |
| Hot tub / spa | $49.75 | $597 | 1,500W running 25% of 24 h |
| EV charger (Level 2 home) | $65.33 | $783 | 37 miles a day at 3.5 mi/kWh, 10% charging loss |
| Treadmill | $4.98 | $59.66 | 900W for 1 h a day |
| Vacuum cleaner | $1.11 | $13.26 | 0.7 kWh a cycle, 2 cycles a week |
| Hair dryer | $0.83 | $9.94 | 0.15 kWh a cycle, 7 cycles a week |
| Aquarium (heater + pump + light) | $9.95 | $119 | 150W running 50% of 24 h |
| Crypto mining rig | $398 | $4,772 | 3,000W for 24 h a day |
| 3D printer | $3.98 | $47.72 | 120W for 6 h a day |
Each figure comes from that appliance's own usage model — a fridge is costed on how much of the day its compressor runs, a dishwasher on energy per cycle and cycles per week, an EV on miles driven. Open any calculator to change the assumption to yours.
Data basis
- Electricity price
- U.S. Energy Information Administration, Electric Power Monthly, Table 5.6.B, June 2026 year to date, released 2026-08-26. Retrieved 2026-09-11. Average residential revenue per kWh. A benchmark average, not a utility tariff — it excludes the fixed charges, tiers, time-of-use windows, taxes and fuel adjustments on a real bill.
- International prices
- rounded typical household tariffs for each market, in that market's own currency unless the row says US$ equivalent. These are planning benchmarks with no single primary source; enter the per-kWh price from your own bill for an accurate figure.
