| Scenario | Length (m) | Height (m) | Width (m) | Sides | Top | Productivity (m²/hr) | Difficulty |
|---|---|---|---|---|---|---|---|
| Residential boundary hedge | 20 | 1.6 | 0.7 | 2 | Yes | 55 | 1.0 |
| Freestanding feature hedge | 12 | 2.0 | 0.9 | 4 | Yes | 35 | 1.2 |
| Tight-access site hedge | 15 | 1.8 | 0.8 | 2 | No | 40 | 1.5 |
Use the table to pick realistic productivity and difficulty values for your site conditions.
A = (sides × L × H) + (top × L × W)
V ≈ A × d × (1 + waste%) where d is trim depth in meters.
t_work = (A / productivity) × difficulty
t_total = t_work + setup
C = (t_total × rate × crew) + equipment + disposal + contingency
Landscape trimming is often treated as a minor task, yet it affects access, visibility, and final presentation. A defined trimming scope reduces delays for fencing, paving, and exterior finishing. When hedges are along temporary haul routes, trimming can improve clearance and reduce rework from broken branches and blocked paths.
The key input is trimmed area, not just hedge length. A typical boundary hedge trimmed on two sides has area 2 × L × H. A freestanding hedge may require three or four sides. If the top is shaped, add L × W. These additions commonly raise workload by 15–40%.
Handheld electric trimmers can achieve 40–70 m²/hr on light growth. Dense evergreen hedges may fall to 25–45 m²/hr, especially with precise lines. Two-person crews often move faster due to continuous cleanup and repositioning. This calculator lets you set productivity and apply a difficulty multiplier.
Obstacles such as parked vehicles, narrow sidewalks, slopes, or overhead services reduce output. A difficulty factor of 1.2 is common for moderate obstacles, while 1.5–2.0 fits tight-access or heavy-growth conditions. Use the travel/setup minutes to cover protection sheets, cones, and final blow-down.
Clippings volume is approximated from trimmed area times trim depth. A 2 cm cut across 100 m² equals about 2.0 m³ before waste. Loose material “fluffs” in bins, so 10–25% waste is typical. This estimate helps size bags, schedule haul-off, and avoid multiple dump trips.
Total cost combines labor, equipment, and disposal. Labor is computed from total hours, crew size, and an hourly rate. Equipment includes a fixed allowance for blades and fuel plus an hourly rate for wear or rentals. Disposal is tied to estimated volume and a per‑m³ rate.
Trimming should be scheduled before façade cleaning, painting, and final inspections. Wet weather can slow work and increase cleanup time. If multiple trades share access, plan trimming windows to prevent debris on fresh concrete or coatings. A small contingency, often 3–10%, covers unknown density and interruptions.
Define finish expectations: flat-top, tapered sides, or rounded profile. Better finish quality may require slower passes and extra cleanup. Always consider PPE, cord management, and safe ladder practices where height is significant. Strong estimates align scope, time, and cost into a predictable outcome.
It is the number of vertical faces you will cut. Boundary hedges often have two sides. Freestanding hedges may need three or four sides, increasing trimmed area and time.
If the top is shaped or leveled, include it. The calculator adds L × W area, which can materially increase hours on wide hedges.
Use past crew performance when available. Light growth can reach 40–70 m²/hr. Dense hedges or precision lines may drop to 25–45 m²/hr. Adjust with difficulty for obstacles.
Enter the average thickness removed, such as 1–3 cm for maintenance, or higher for corrective trimming. Depth affects the clippings volume and disposal cost only.
Cut material expands when collected and loaded. A 10–25% waste factor is common. Increase it for fluffy clippings, wet material, or limited compaction in bags and bins.
The calculator estimates site hours based on area and productivity, then applies crew size to labor cost. Larger crews can finish sooner in calendar time, but total labor spending may rise.
For routine maintenance, 3–7% is often enough. For unknown growth density, restricted access, or strict finish requirements, 8–15% can be reasonable to protect your estimate.
Trim smarter, budget better, and finish every hedge beautifully.
