On these numbers people are clearly cheaper. Even running flat out, one robot would not displace enough work to pay for itself.

U.S. Bureau of Labor Statistics

BLS OEWS May 2025 national median hourly wage, SOC 37-3011.

U.S. Bureau of Labor Statistics

Wages and salaries were 70.0% of total employer compensation cost for private industry workers in June 2026 (ECEC), so total cost = wage / 0.70.

ilostat.ilo.org

Nominal 4.4% a year, 2015-2025 (ILOSTAT hourly earnings).

Premissa

Acres per hour for an experienced operator on a commercial zero-turn mower.

Premissa

Your mower's fuel and ownership cost per hour. Default 0 ignores it.

Robô
Premissa

Autonomous mower acres per hour relative to a person.

Scythe Robotics

Scythe M.52 Standard lease from $1,800/month (includes 40 autonomous acres; more acres cost more).

Premissa

Site mapping and crew training.

Premissa

Lease term in years.

Premissa

Availability.

Premissa

Work lost to faults.

Premissa

Trimming, slopes and obstacles a person still handles.

Premissa

Crew minutes per robot-hour: transport, supervision while it mows nearby.

Premissa

kWh per robot-hour.

Premissa

Electricity price per kWh (USD). Check your bill; energy is rarely a big line.

Finanças
Premissa

Annual financing / discount rate. Nobody publishes yours; 8% is a round mid-2026 commercial borrowing guess.

Premissa

Years in the NPV comparison.

Premissa

Share of a human service price that is labour (rises with wages). Used to escalate and to adjust US service prices to other countries.

Premissa

Share of a robot service price that is labour (pilot, technician). The rest is equipment, which learning curves make cheaper.

Premissa

Share of a lease or RaaS fee that pays for hardware (learns down). The rest is service and support (moves with wages).

What the spreadsheet misses

Segurança
Mower injuries and heat stress are real; a robot takes the operator off the seat.
Qualidade
Consistent stripes; trimming still manual.
Flexibilidade
Crews move between sites fast; robots need transport and maps.
Edge cases
Public parks with people and dogs need supervision.
Customer experience
Quiet electric mowers allow early or late work.
Jobs and redeployment
Crews shift to trimming, planting and supervision; labour shortages are the usual driver.
Regulamentação
Check local rules for unattended machines in public spaces.
