In landscape estimating, the most dangerous number on your spreadsheet is your hourly labor rate. Many contractors calculate their bids using the base wage they pay their employees. If they pay a foreman $25 an hour, they estimate the job at $25 an hour. This fundamental error is the fastest route to bankruptcy.
Every employee costs significantly more than their hourly wage. To estimate profitably, you must calculate the Labor Burden. This is the true cost of employing someone, encompassing payroll taxes, worker’s compensation, liability insurance, health benefits, and most importantly, unbillable downtime.
Understanding Unbillable Time
You pay your crew for an 8-hour day, but they are rarely installing materials for 8 hours. The time spent loading trucks at the yard, driving through morning traffic, picking up materials at the nursery, and cleaning up the site is “unbillable time.” If you do not factor this inefficiency into your estimating rates, you are paying for those hours entirely out of your net profit.
Pro Tip: The 80% Efficiency Rule
In the landscape construction industry, a highly efficient crew only achieves about 80% billable time. That means out of a 40-hour work week, you can only realistically charge the client for 32 hours of actual site production. Your estimating rates must be inflated to recover the cost of those 8 “lost” hours.
Breaking Down the Burdened Rate
To find your true cost of labor, you must add all indirect employee costs to the base wage. Here is a typical breakdown demonstrating why your estimating rate must be significantly higher than the employee’s paycheck:
| Cost Category | Impact on Base Wage (Approximate) | Why It Matters |
|---|---|---|
| Payroll Taxes (FICA, Medicare) | + 7% to 10% | Mandatory employer contributions. |
| Worker’s Compensation Ins. | + 8% to 15% (varies by state/role) | Landscape construction carries high liability rates. |
| Benefits (Health, PTO, Retirement) | + 10% to 20% | Required for retaining high-quality crew members. |
| Unbillable Time / Inefficiency | + 20% | Recovers drive time, loading, and weather delays. |
Calculate Your True Costs Instantly
Manually calculating the exact burden rate for every individual employee and blending them into a crew average is a complex accounting task. A miscalculation here means you lose money every single hour your crew is on site.
