Calculate your cost
Start with the example below, then replace the wattage, daily runtime, and rate with the numbers for your electric lawn mower.
This setup uses about 23 kWh in a 30-day month.
Please enter valid values within the ranges shown.
| Schedule | Hours/day | Cost/month |
|---|---|---|
| Half runtime | 0.25 | $2.12 |
| Page example | 0.5 | $4.24 |
| Longer runtime | 0.75 | $6.36 |
Same 1,500-watt input and 18.83¢/kWh rate; only runtime changes.
Formula for the page example
1.5 kW × 0.5 hr × $0.1883 = $0.14 per day
Convert watts to kilowatts, multiply by the active hours used each day, then multiply by the electricity price in dollars per kWh. Multiply the daily result by 30 for the monthly estimate shown above.
How to read this estimate
Electric lawn mowers are powerful and environmentally friendly, replacing gas costs with a small, predictable electricity charge per mow.
Use this as a baseline until you can check the label or measure the electric lawn mower directly. Model, settings, condition, climate, and household routine can all change the result.
What changes the cost?
- 01
Motor wattage or battery size
- 02
Height and thickness of grass
- 03
Yard terrain (hills vs. flat)
Ways to spend less
- Mow regularly so the motor doesn’t struggle against tall grass.
- Keep the mower blade sharp for a cleaner, faster cut.
- Avoid mowing wet grass, which drags the motor down.
