How Much Does It Cost to Run a Treadmill in Washington? (2026)
A motorised treadmill draws 300 watts at a walking pace and up to 1,500 watts running at speed with a heavier user. A 45 minute session typically uses about half a kWh.
A typical treadmill (700 W) costs $0.10 per hour, or about $2.35 per month at 0.75 hours a day in Washington. Average running cost
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low 300 W | $0.045 | $0.034 | $1.01 | $12.24 |
| Typical 700 W | $0.10 | $0.078 | $2.35 | $28.57 |
| High 1,500 W | $0.22 | $0.17 | $5.03 | $61.22 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 0.75 h/day ≈ 192 kWh per year.

In Washington, with electricity at 14.9¢ per kWh (source: EIA Table 5.6.A, 2026-06), a typical treadmill costs $0.10 per hour and about $28.57 per year at 0.75 hours a day. That is about 19% less than the national average for the US ($2.89 per month), because electricity in Washington costs 14.9¢ per kWh against 18.3¢ nationally. Each $1.00 of electricity buys roughly 9.6 hours of use.
How to lower the cost of running a treadmill
- Unplug it or use the power switch between workouts. Some models draw 3 to 5 watts idle.
- Lubricate the belt on schedule. A dry belt makes the motor work harder.
- Incline walking uses less motor power than fast running for a similar workout.
In standby it draws about 3 W, which adds roughly 26 kWh ($3.92) per year if it is never unplugged.
