Lawn-Care Job Costing Calculator

How this calculator works

This calculator computes the true per-job net profit for a lawn care job by building the complete cost picture: loaded labor cost across both service time and drive time, truck fuel, equipment depreciation, product/material cost, and overhead allocation. The output is net profit per job, gross margin percentage benchmarked against the NALP healthy range, total all-in job cost, and the breakeven revenue floor — the minimum price at which the job covers all its costs.

Most lawn care operators know their gross revenue per job but do not account for the full cost stack, particularly drive time and equipment depreciation. These omissions produce systematic over-estimates of per-job profitability that compound across a season's worth of under-priced work.

Why drive time must be included

Drive time between job sites is a real labor cost regardless of how the business is structured. For a W-2 employee, the Portal-to-Portal Act (29 U.S.C. § 254) generally requires compensation for travel between work sites during the workday — driving from the first job to the second job is compensable work-directed travel, not commuting. For a solo owner-operator, drive time represents the operator's own time that cannot be simultaneously deployed on revenue-producing service work.

The practical impact is significant. A 45-minute mowing job with 5 minutes of drive time produces an effective labor efficiency of 45/50 = 90% — only 10% of total labor time is non-productive. The same job with 30 minutes of drive time produces an effective labor efficiency of 45/75 = 60% — 40% of total labor time is non-productive driving. At a $45/hr loaded labor rate, that 25 additional minutes of drive time costs $18.75 and reduces per-job gross margin by roughly 25 percentage points on a $75 job.

Route density — clustering jobs geographically so that drive time between stops is minimized — is the single highest-leverage profitability improvement available to a solo lawn care operator. The crew-capacity calculator in this cluster models the capacity and revenue impact of route density choices.

Equipment depreciation allocation

Equipment depreciation is frequently omitted from per-job cost estimates because it does not appear as a cash outflow in the current period. The cash was spent at purchase; the depreciation represents the amortized cost of replacing the asset when it wears out. Operators who track zero equipment depreciation are effectively spending future replacement capital without accounting for it — the new mower purchase, when it comes, appears as an unplanned large expense.

The correct per-job depreciation allocation is: equipment purchase price divided by total expected productive hours, multiplied by the hours of use per job. A commercial zero-turn priced at $10,000 with an expected 1,500-hour productive life depreciates at $6.67 per productive hour. Add string trimmer ($1,000 new, 500 hours), backpack blower ($600 new, 800 hours), and trailer ($4,000 new, 2,000 hours) and a solo residential crew running a 45-minute mowing job carries approximately $6-$10 of equipment depreciation per job. The calculator defaults to $8 per job as a representative figure.
