Frequently Asked Estimating & Technical Questions
Key formulas, building code standards, and estimating rules for this trade category.
What is the difference between markup percentage and gross profit margin on a contractor bid?
Markup is the percentage added to your direct job costs, while gross margin is the percentage of the final selling price that is profit. To achieve a true 20% gross margin, you must divide your total cost basis by (1 - 0.20), which equals a 25.0% markup on cost.
How much overhead percentage should a small contracting business allocate?
Most residential and light-commercial trade contractors carry 10% to 18% in general and administrative overhead (insurance, fleet vehicles, licensing, software, and office staff). Our construction estimate template separates overhead allocation from net profit margin so neither is eroded.
What is a standard contractor deposit and milestone payment schedule?
For residential remodeling and exterior builds, a standard 30 / 40 / 30 draw schedule collects 30% upon contract signing to cover material delivery, 40% upon rough-in or framing completion, and the final 30% upon walkthrough sign-off.
Why should roofing contractors present a Good / Better / Best 3-tier proposal?
Presenting three side-by-side shingle tiers (3-Tab Economy, Architectural Laminated, and Designer/Standing Seam Metal) anchors the homeowner's decision around your own options rather than competing bids, increasing average ticket size by 18% to 25%.
