Start with the full scope of work
A reliable estimate begins with a clear list of tasks, quantities, materials, labor, and any subcontracted work. Walk through the job scope before choosing a price, and note assumptions or exclusions so the customer understands what the quote covers.
Calculate labor and material costs
Estimate labor hours by task and multiply them by the appropriate labor cost. Add material quantities, expected purchase prices, delivery, rentals, and subcontractor quotes. Include a reasonable allowance for waste or uncertain conditions where appropriate, and document how you arrived at each number.
Account for overhead and target profit
Job costs are not the whole business cost. Consider insurance, vehicles, tools, software, administration, and other overhead. Decide how overhead is allocated and how your business sets prices. Markup and margin are different, so check the math before finalizing a quote.
Review the estimate before sending it
- Confirm measurements and quantities.
- Check labor hours and current supplier pricing.
- List allowances, exclusions, and payment milestones.
- Compare the planned price with your target margin.
- Save the assumptions so you can compare estimated and actual costs later.
