Free Construction Estimate Template: How to Price a Job Line by Line

1. Break the job into line items

Work through the job in the order it will be built — site work, foundations, framing, roofing, openings, finishes. Each line needs a quantity, a unit (sq ft, lin ft, each) and two rates: material cost per unit and labour hours per unit.

• Measure from drawings or a site visit and note the source of each quantity.
• Use your own supplier prices, not national averages.
• Track real production rates on a few jobs — they're the most valuable number in your estimate.

2. Add tax, overhead and contingency

Sales tax usually applies to materials, not labour (check your jurisdiction). Overhead covers costs that aren't tied to one job: insurance, vehicles, office, software. Contingency covers the unknowns — older homes and renovations deserve more.

3. Apply profit — and check your margin

A 12% markup is not a 12% margin. If you add 12% profit to cost, your margin on the final price is about 10.7%. The calculator shows both so you can see what you're really earning.

4. When to move beyond a free template

If you estimate every week, a reusable item library saves hours: type a code and quantity and the description, unit and prices fill in. That's what the Contractor Professional Estimating System is built around.
