Free lawn mowing cost calculator. Compare your DIY mowing cost against hiring a lawn service by lawn size and frequency, and see your exact annual savings.
Your results will appear here.
Enter your values and press Calculate.
The calculator multiplies your DIY cost per mow and the service price per visit by the number of mows per year implied by your frequency: weekly means 26 mows over a typical 26-week mowing season, every two weeks means 13, monthly means 6, and one time means a single cut. Annual savings is the service total minus the DIY total; a negative savings figure means hiring the service is cheaper at your numbers. Lawn size is recorded for context, since service quotes are usually size-based. All results are planning estimates, not professional financial advice.
The formula behind this calculator is deliberately simple and transparent. The number of mows per year comes from your frequency: weekly means 26 mows over a typical 26-week mowing season, every two weeks means 13, monthly means 6, and one time means a single cut. DIY annual cost is your DIY cost per mow (fuel, oil, blade sharpening and equipment wear) multiplied by mows per year. Service annual cost is the price per visit multiplied by mows per year. Annual savings is the service total minus the DIY total.
Worked example with the defaults: a 5,000 sq ft lawn mowed weekly, with a DIY cost of $12 per mow and a service price of $55 per visit. 26 mows times $12 gives $312 a year DIY; 26 times $55 gives $1,430 a year for the service; the saving is $1,118.
A negative savings figure is information, not an error: it means the service is cheaper than DIY at the numbers you entered, which happens when equipment costs are high or service prices are low. All results are planning estimates, not professional financial advice.
Start by choosing your currency. Enter your lawn size in square feet or square meters; this is the number most service quotes are based on, so measuring it correctly (see the FAQ below) makes the whole estimate more realistic. Pick your mowing frequency, then enter your DIY cost per mow: add up fuel per mow, plus a share of yearly oil, blade and maintenance costs divided by your mows per year, plus a share of the mower's purchase price spread over its expected life.
Next, enter the lawn service price per visit. If you have a written quote, use it; otherwise, 2026 published pricing puts the national average visit at about $45 to $75 (lawnlove.com) or around $50 (calcusense.com). Press Calculate to see the DIY annual cost, the service annual cost and the exact saving side by side. Change any input to see how the comparison moves, for example switching from weekly to bi-weekly service.
The published numbers favor DIY, but the gap depends on your equipment. A 2026 guide from askdoss.com puts annual mowing-only costs at $200 to $500 a year DIY versus $1,500 to $4,000 a year for a professional service, over a 25 to 32 visit season. Lawnlove.com's 2026 data shows the same pattern: DIY starts at $135 to $3,940 upfront depending on the mower type, plus $100 or more per season in gas, oil, blades and filters, while a pro visit costs $45 to $75 and takes 30 to 60 minutes of someone else's time.
Here is the full DIY cost breakdown for context: the equipment choice is what moves the DIY number most. A walk-behind mower costs roughly $250 to $600 and lasts 8 to 10 years, which is only $30 to $75 a year in equipment cost (onlycalculators.com); a riding mower costs $1,500 to $4,000 and only makes financial sense on large lawns where it replaces many expensive service visits. On a typical quarter-acre lawn at $50 a visit weekly, the service bill reaches about $1,400 over a 28-week season (localservicecalculator), so a homeowner who already owns a walk-behind mower saves four figures a year by doing the lawn care himself, while a homeowner buying a riding mower to save $1,400 a year may never break even. The calculator above does this exact comparison with your own numbers, so you can decide whether to hire a service or mow it yourself.
Lawn size is the biggest price driver, and published 2026 tables show it clearly. Calcusense.com lists weekly prices of $30 to $45 for small lawns under 5,000 sq ft, $45 to $65 for a quarter-acre, $65 to $90 for a half-acre, $90 to $140 for a full acre, and $150 to $300 or more for two acres plus. LawnStarter.com's 2026 ranges run $41 to $61 per visit for up to a quarter-acre and $278 to $449 for over two acres. Per square foot, the market average sits around $0.01 to $0.06, averaging about $0.035 (calcusense.com), and these published rates vary by region, which works out to roughly $35 per 1000 sq ft.
Frequency matters too: bi-weekly service costs 15 to 30 percent more per visit than weekly, and one-time mows run 20 to 40 percent above the recurring rate (calcusense.com), because setup time is fixed and taller grass takes longer. Many companies also apply a minimum charge of $30 to $50 per visit regardless of lawn size. Grass condition is the other surprise surcharge and directly affects the final price: overgrown grass of 12 inches or more can add 50 to 80 percent or require a separate cleanup visit (onlycalculators.com), and some companies simply double the rate for untouched lawns. Region plays a role as well: Northeast and coastal cities run 20 to 40 percent above the national average, while the Midwest and rural South sit below it (onlycalculators.com). Some companies adjust quotes by zip code to reflect local labor costs.
The cheapest legitimate discount is a seasonal contract: prepaid or contract customers typically save 5 to 15 percent versus per-visit pricing (askdoss.com reports 10 to 15 percent, lawnlove.com 5 to 10 percent). Choosing your frequency carefully is the second lever. Localservicecalculator's 2026 national benchmark of a 28-week season shows weekly at $50 a visit costs $1,400, bi-weekly at $60 a visit costs $840, and monthly at $75 a visit costs $525: fewer visits can cut the annual bill even when each visit costs more.
For the DIY route, buy only as much mower as your lawn needs, sharpen blades instead of replacing the mower, and keep fertilizer and weed-control spending modest: askdoss.com budgets DIY products at $100 to $300 a year. If you mow lawns for pay, the same published ranges are your pricing guide: $0.01 to $0.06 per square foot with a $30 to $50 minimum charge, plus $10 to $20 for edging and $8 to $15 for cleanup as add-ons (calcusense.com, onlycalculators.com). However you price or buy, get everything in a written quote before the season starts, since verbal estimates are where billing disputes begin.
Time is the hidden cost of DIY, and it is worth estimating honestly. Onlycalculators.com's DIY model shows that a 21-inch walk-behind deck at 3 mph with 80 percent efficiency covers about 24,000 sq ft per hour, so a 5,000 sq ft lawn takes roughly 12 to 15 minutes of mowing plus trimming time, and you should add 20 to 30 percent for turning and overlap. That is about half an hour a week for a typical suburban lawn, or roughly 13 hours over a 26-week season.
If your time is worth $20 an hour, that adds about $260 a year in implied cost, which is why many owners on small lawns mow themselves (the service would cost $1,400 plus) while owners with long commutes or large lawns happily outsource. Riding mowers and robot mowers change the equation again: higher equipment cost, but a fraction of the time per mow.
Published 2026 guides put the national average at roughly $45 to $75 per visit (lawnlove.com), $44 to $71 with an average of $57 (lawnstarter.com), and about $50 (calcusense.com). A typical quarter-acre lawn runs $1,200 to $2,800 a year depending on frequency and region. Your lawn size, mowing frequency and local market move your number up or down from these averages.
Usually it is cheaper to mow your own lawn. Askdoss.com's 2026 figures show mowing-only costs of $200 to $500 a year DIY versus $1,500 to $4,000 a year for a professional service. The gap shrinks if you buy an expensive riding mower, need many add-ons like fertilization, or place a high value on your own time. Use the calculator above to compare your exact numbers.
It depends on season length and frequency. Calcusense.com's 2026 data shows a quarter-acre lawn on bi-weekly service costing $715 to $825 a year in northern states and $990 to $1,100 a year in the South, where the mowing season is longer. Full-year totals for weekly service typically land between $1,200 and $2,800, which works out to roughly $100 to $230 a month over the mowing season.
Bi-weekly visits cost 15 to 30 percent more per visit than weekly (calcusense.com), but you get half as many visits, so the season total is often lower. At a national benchmark of $50 a visit weekly over 28 weeks ($1,400) versus $60 a visit bi-weekly over 14 visits ($840), bi-weekly wins on price (localservicecalculator). Weekly is better for lawn health during fast-growth months.
One-time mows are priced 20 to 40 percent higher than regular recurring visits (calcusense.com) because the company absorbs the same travel and setup cost for a single job, and the grass is usually taller and takes longer to cut. Overgrown lawns of 12 inches or more can cost 50 to 80 percent extra or need a separate cleanup visit (onlycalculators.com).
A 21-inch walk-behind mower at 3 mph with 80 percent efficiency covers about 24,000 sq ft per hour, so a 5,000 sq ft lawn takes roughly 12 to 15 minutes of mowing plus trimming, with 20 to 30 percent added for turning and overlap (onlycalculators.com). Budget around half an hour per mow for a typical suburban lawn, or 13 hours over a 26-week season. A lawn you mow yourself takes that half hour out of every week, jobs in tall grass take longer still, so value it honestly: at $20 an hour the time alone adds about $260 a year.
A standard visit covers mowing, trimming edges and blowing clippings off driveways and paths. Common extras are edging at $10 to $20, blowing and cleanup at $8 to $15, and bagging or hauling clippings at $15 to $25 (onlycalculators.com). Fertilization, weed control and aeration are separate lawn care services with their own pricing, not included in the standard visit.
Measure the length and width of the lawn in feet, multiply them for the square footage, then subtract the house, driveway, patios and garden beds. For irregular shapes, split the lawn into rectangles and add them up. Satellite measurement tools can do this from an aerial photo. Services typically charge $0.01 to $0.06 per square foot (calcusense.com), so an accurate area keeps quotes honest.
Yes, and it can affect it a lot. Overgrown grass of 12 inches or more can add 50 to 80 percent to the visit or require a separate cleanup visit (onlycalculators.com), and some companies simply double the rate for lawns that have not been touched in months. Tall, wet or weedy grass slows the mower and usually adds a bagging or hauling charge of $15 to $25.
