Real cost savings
Lawn services run $50–$300+ per week. Most Zippy clients hit positive ROI by year two and save thousands by year three.

What you pay now — $50 to $300+ a week
A bare-bones mow-and-go on a small suburban lot runs $40–60 a visit. Add edging, blowing and a half acre and it's $60–100. An acre-plus, or a full-service contract that mows, edges, tends beds and cleans up, is $150–$300 and more. Whatever your number is, multiply it by about 30 visits a season, then add the 3% creep every invoice picks up year over year — and it never stops.
| Per visit | Per season (+ fertilizer) | 7 years, with creep | Robot pays for itself in |
|---|---|---|---|
| $50 | $1,650 | $12,643 | year 3 |
| $75 | $2,400 | $18,390 | year 2 |
| $100 | $3,150 | $24,137 | year 2 |
| $150 | $4,650 | $35,630 | year 1 |
| $200 | $6,150 | $47,124 | year 1 |
| $300 | $9,150 | $70,112 | year 1 |
Half-acre lawn, weekly visits for 30 weeks plus a $150 fertilizer program (spent either way), 3% yearly price creep on both sides. The robot column is the Navimow X430 at $2,499 + $700 install, with the running costs below.
What the robot costs, all-in
No hidden lines. For the reference half-acre lawn the mower that fits is the Navimow X430. Here's everything we count:
- $2,499 — the mower (catalog price, same as the store)
- $700 — professional install and mapping, once
- $10 a year — electricity (about 54 kWh at $0.18/kWh)
- $99 a year — blades, upkeep and support
- $489 every 3 years — a replacement battery pack, modeled conservatively
- −25% on fertilizer — the micro-clipping credit (on a $150 program)
Year by year — $60 a visit vs the robot
| Year | Lawn service, cumulative | Robot, cumulative | Difference |
|---|---|---|---|
| Year 1 | $1,950 | $3,420 | −$1,470 |
| Year 2 — pays for itself | $3,959 | $3,648 | +$310 |
| Year 3 | $6,027 | $4,372 | +$1,655 |
| Year 4 | $8,158 | $4,614 | +$3,545 |
| Year 5 | $10,353 | $4,862 | +$5,490 |
| Year 6 | $12,613 | $5,608 | +$7,005 |
| Year 7 | $14,942 | $5,872 | +$9,070 |
That's the default scenario — and it's the conservative one. Most of the homeowners we install for are paying more than $60 a visit, which is why year two is the typical crossover and why the year-three number ($1,655 ahead here, at a modest $60) turns into thousands on a full-service contract.
Where the savings hide
- No price creep. The mower's price is the mower's price. A service invoice rises every year, forever.
- No gas, oil, plugs, belts or tune-ups — and no riding mower to replace in ten years. If you mow yourself today, that's several hundred dollars a season you stop spending.
- Less fertilizer. Daily micro-clippings feed the lawn continuously — 25% off the program in our model. Why that works.
- No missed weeks. Rain, holidays and crew shortages don't skip your lawn; the robot lives there.
- Your Saturdays. Roughly 40 hours a season on a half acre if you mow yourself — the full calculator prices them at whatever you say they're worth.
The honest part.
- Edging is never counted as a saving. No robot we sell string-trims. If your crew edges today, that job lands on you or on our crew.
- The battery is a real line. We model a pack every 3 years so the number can only get better, not worse.
- Lot size isn't lawn size. Across 294 lawns mapped with our free tool the median mowable area is 0.43 acres — the house, drive, beds and pool come out. The mower that fits, and its price, follow from the real number, which is why the app's ROI beats any guess you type here.

Common questions
Is a robot mower really cheaper than a lawn service?
Over a normal ownership window, almost always. A $60-a-visit weekly service on a half-acre lawn is about $1,950 a season and creeps up every year; the Navimow X430 that fits that lawn is $2,499 plus $700 installed, then about $221 a year to run. In that scenario it pays for itself in year 2 and you keep about $9,070 over 7 years — every assumption is printed on this page.
Why do you say most clients hit positive ROI by year two?
Because most of the people we install for are paying more than the $60-a-visit default — bigger lawns, edging and blowing included, or a full-service contract at $100–$300 a week. At $100 a visit the crossover is year 2; at $150 and up it's inside the first season or two. A small lawn on a bare-bones $50 mow-and-go takes longer. The ladder on this page shows every rung.
What does it cost to run?
Very little. On a half-acre lawn the Navimow X430 pulls about 54 kWh a year — roughly $10 at the U.S.-average rate — plus about $99 a year for blades and upkeep. We also model a replacement battery pack ($489) every 3 years, which is conservative; most packs last longer.
Is it worth it if I mow the lawn myself?
In cash alone, only if you put a price on your time. The full calculator asks what an hour of your Saturday is worth and counts gas, maintenance and the mower wearing out — on a half-acre lawn that's roughly 40 hours a season handed back. Most DIY owners buy the robot for the hours, and the lawn, more than the dollars.
What's not included in the savings?
Edging. No robot we sell string-trims a bed edge or a fence line, so the calculator never counts edging as a saving — if a crew edges for you today, that job lands on you (about 15 minutes every week or two) or on our crew as part of a robotic lawn service.
