There’s a common estimating habit that quietly kills contractor profit margins. It’s called the fudge factor.
Instead of calculating actual direct costs, labor hours, materials, subcontractors, contractors add a vague percentage on top and hope it covers everything. The problem: when you don’t know where your costs actually come from, you can’t fix them, track them, or improve them.
Estimating and bidding are two different things. Estimating is math: figure your direct costs first, cleanly and completely. Bidding is strategy: then you add overhead and profit on top. When you mix the two, your margins are invisible.
Capable contractors estimate within a few percentage points of actual job cost — not because they’re guessing better, but because they’ve built a system. Labor productivity records. Supplier quotes. Real cost history by job type.
If you’re throwing a fudge factor into every bid, you’re not pricing. You’re gambling.
