Electric vs Gas Lawn Mower: 10-Year Cost Comparison (2026)
An electric mower costs about $4/year in electricity vs $50–$75 in gas and oil — and skips the tune-ups. Here's the full 10-year cost breakdown.
By ElectricVsGas
Over 10 years, a battery electric mower and a gas mower end up costing about the same to own — the electric’s higher purchase price is offset by near-zero running and maintenance costs. The deciding factors usually aren’t money: they’re lawn size, noise, fumes, and how much you enjoy small-engine maintenance.
For a quarter-acre suburban lawn, electric has quietly become the default. For large properties over an acre, gas still has real advantages. Run your lawn size through the electric vs gas lawn mower calculator for your own 10-year numbers.
Running Cost: Electric Is Almost Free
A typical lawn takes about 30 mows a season. A gas push mower burns roughly 0.5 gallons per hour of mowing; a battery mower uses about 0.5–1 kWh per charge.
Electricity to charge a mower for a whole season costs about the price of a coffee. Gas fuel is modest too — but gas mowers carry an ongoing maintenance tax: oil changes, air filters, spark plugs, fuel stabilizer, carburetor cleaning, and the occasional tune-up. Those add $40–$80/year and a fair amount of hassle that electric simply doesn’t have.
10-Year Total Cost of Ownership
| Electric (battery) | Gas | |
|---|---|---|
| Mower purchase | $300–$600 | $200–$450 |
| Replacement battery (~year 5) | $100–$250 | — |
| Fuel/energy (10 yr) | ~$40 | ~$650 |
| Maintenance (10 yr) | ~$100 | ~$600–$900 |
| 10-year total | ~$550–$1,100 | ~$1,450–$2,400 |
Once you account for fuel, oil, and upkeep over a decade, electric typically comes out lower in total cost — even after factoring in a mid-life battery replacement. The gap widens the longer you keep the mower.
Beyond Cost: The Real Decision Factors
Electric advantages: Push-button start (no pull cord), about half the noise (75 dB vs 95 dB), no fumes or carbon emissions, no fuel storage, no winterizing, minimal maintenance, lighter weight.
Gas advantages: Unlimited runtime (just refuel), more torque for thick or wet grass, no battery to degrade or replace, better suited to large lots, and no charging downtime mid-mow.
When Gas Still Wins
- Large lots (over ~3/4 acre). A single battery charge typically covers 1/3 to 1/2 acre; bigger lawns need spare batteries (expensive) or a riding mower, where gas runtime is hard to beat.
- Tall, wet, or rough grass. Gas engines deliver more sustained power for demanding conditions.
- Long sessions without breaks. Refueling takes seconds; recharging takes an hour or more.
For lawns under half an acre with normal grass, none of these usually apply — which is why electric has become the mainstream choice for typical suburban yards.
Frequently Asked Questions
Is an electric or gas lawn mower cheaper over time?
Over 10 years, electric usually costs less in total — roughly $550–$1,100 versus $1,450–$2,400 for gas — because its near-zero fuel and maintenance costs offset a higher purchase price, even including a mid-life battery replacement. The savings grow the longer you own the mower.
How much does it cost to charge an electric mower?
Almost nothing — about 0.5–1 kWh per charge, or roughly $0.10–$0.19 at national average rates. A full season of mowing costs only a few dollars in electricity, compared to $50–$75 in gas for a comparable gas mower.
Can an electric mower handle a large yard?
Up to a point. A single battery charge typically covers 1/3 to 1/2 acre. For larger lots you’ll need a spare battery (which adds cost) or a riding mower. Gas remains the more practical choice for properties over about 3/4 acre or lawns that require long, uninterrupted mowing sessions.
Do electric mowers require maintenance?
Very little — no oil changes, spark plugs, air filters, or fuel system upkeep. Maintenance is limited to cleaning, blade sharpening, and eventually replacing the battery (around year 5, $100–$250). Gas mowers need regular oil, filters, plugs, and periodic tune-ups, which is the main hidden cost of owning one.
How long does an electric mower battery last?
A mower battery typically lasts 3–5 years or several hundred charge cycles before its runtime noticeably declines. Replacement costs $100–$250 depending on the platform. Storing the battery properly (cool, partially charged, indoors over winter) meaningfully extends its life.
Data sources: Energy use (~0.75 kWh/charge) and fuel use (~0.5 gal/hour of mowing) from manufacturer specifications and small-engine consumption data. Electricity price $0.19/kWh (EIA, March 2026) and gasoline $4.10/gal (EIA/AAA, June 2026). Maintenance cost estimates for gas mowers (oil, filters, plugs, tune-ups) from small-engine service pricing. Equipment and battery replacement costs from retailer pricing (EGO, Ryobi, Honda, Toro), 2025–2026. Noise levels (electric ~75 dB, gas ~95 dB) from manufacturer and EPA data. Assumes ~30 mows per season; totals scale with lawn size and usage.
