Gas vs Electric Mower Cost Calculator
Battery mowers cost more up front but less to run. This calculator estimates your 5-year total cost of ownership for each, using your lawn size and local energy prices.
Assumptions: a typical walk-behind mower covers ~0.25 acre on ~0.18 gal of gas, or ~0.9 kWh of battery charge. Gas mowers need ~$25/yr of oil, filters, spark plugs & tune-ups; battery packs lose capacity and we budget one ~$120 replacement over 5 years. Adjust the inputs to match your setup — these are research-based estimates, not a guarantee.
