Calculator Inputs
Formula Used
The calculator estimates surface area first, then converts the trimmed surface into removed volume. Labor and cost are added afterward for a practical construction estimate.
Side Area = Hedge Length × Hedge Height × Number of Side Faces Top Area = Hedge Length × Top Width Trimmed Area = Side Area + Top Area Trim Depth (m) = Trim Depth (cm) ÷ 100 Base Volume Removed = Trimmed Area × Trim Depth Adjusted Debris Volume = Base Volume × (1 + Waste Factor ÷ 100) Crew On-Site Hours = Trimmed Area ÷ (Productivity × Crew Size) + Setup Hours Labor Cost = Crew On-Site Hours × Crew Size × Hourly Rate Total Cost = Labor Cost + Disposal Cost + Overhead CostHow to Use This Calculator

Frequently Asked Questions
1. What does this hedge trimming calculator estimate?
It estimates trimmed surface area, removed debris volume, bag count, labor hours, disposal cost, overhead, and total project cost for a hedge trimming job.
2. Why do I need the hedge top width?
Top width is used only when the top surface is trimmed. It helps estimate the top area and improves debris and labor calculations.
3. What is trim depth in this calculator?
Trim depth is the average thickness removed from the hedge face. Larger trim depth increases debris volume, disposal needs, and total job cost.
4. How is labor time calculated?
The calculator divides trimmed area by productivity and crew size, then adds setup and cleanup hours. This gives estimated crew time on site.
5. What does waste factor change?
Waste factor increases the base debris volume. It accounts for loose clippings, uneven cuts, handling losses, and practical site cleanup allowances.
6. Can I use this for residential and commercial jobs?
Yes. The structure works for both. Enter the actual hedge dimensions, site productivity, crew size, and local pricing to fit your project.
7. Why is debris density needed?
Debris density converts removed volume into estimated weight. This helps with handling plans, disposal estimates, and trailer or bin capacity checks.
8. Can I export the results after calculation?
Yes. After you calculate, the page enables CSV and PDF downloads so you can save or share the estimate quickly.
