Mowing Cost Calculator – Corded, Cordless vs Petrol

Use this cost-per-mow calculator to compare cordless, corded and petrol lawnmowers. Enter lawn size, mowing time and energy prices to see the true cost of each mow and annual mowing costs in UK pounds.

Mowing Cost Calculations

Ever wondered if that roaring petrol mower is secretly guzzling your wallet? Or if your “cheap” electric mower is really saving you much? This calculator cuts through the guesswork. With a few quick entries, your lawn size, mowing time, mower type and fuel or electricity rate, it shows the true cost of each mow and your yearly total.

Mowing Time Spent

No need to think in complicated units like kilowatt-hours or litres per mow, because most of us don’t track that. Instead, you just choose how long you usually mow (15 minutes up to 2 hours) and let the calculator do the maths behind the scenes using realistic energy and fuel consumption averages.

Electric vs Petrol

Electric mowers usually sip around 1.2–1.5 kWh per hour, while petrol models drink roughly 2 litres per hour. Multiply that by your energy price, and you’ll finally see what each trim costs. It’s a handy budgeting tool if you’re comparing mower types or figuring out whether it’s worth switching to cordless or staying with your trusty petrol beast.

Final Word

And there you have it, no more mystery about what your mower’s costing you to keep the grass in line. This tool keeps things brutally honest (and a bit humbling if you’re running a petrol monster every weekend). Adjust the time or the number of yearly mows to see what you’re really spending season-to-season.

If you spot a result that shocks you, share it with your neighbour or send it to your partner as proof that “yes, mowing does cost money.” Want to improve it?
