Free General Contractor Estimate Template

A general contractor manages the most complex projects a homeowner will ever undertake — kitchen remodels, additions, full renovations. Your estimate coordinates multiple trades, hundreds of material selections, and a timeline measured in weeks or months. Getting it right determines whether the project is profitable for you and stress-free for the client.

Break out every trade as its own section

A single lump-sum number tells the client nothing. Break your estimate into sections by trade: demolition, framing, plumbing rough-in, electrical rough-in, HVAC, insulation, drywall, painting, flooring, cabinetry, countertops, tile, and final trim. Each section should show labor and materials separately. This transparency builds trust and makes change orders straightforward — the client can see exactly what they are adding or removing.

Use allowances for client-selected items

Clients rarely finalize every material choice before signing. For items like lighting fixtures, cabinet hardware, tile, and countertops, include a per-unit or per-square-foot allowance. State clearly: "Countertop allowance: $60/sq ft installed. Selections above this allowance will be billed at actual cost." This locks in a budget while giving the client flexibility — and protects your margin from surprise upgrades.

Tie payments to milestones, not dates

Never bill on a calendar schedule — bill on completion milestones. A typical structure: 10% deposit to secure scheduling, 25% at demo complete, 25% at rough-in inspection passed, 25% at finish work start, 15% at final walkthrough and punch list complete. This protects the client (they only pay for completed work) and protects you (you are never financing the project out of pocket for long).

Define your change order process upfront

Every renovation has surprises — hidden water damage, outdated wiring that does not meet code, a client who changes their mind on tile. Your estimate should include a change order clause: all scope changes require written approval before work proceeds, with a line-item cost adjustment and timeline impact. This one paragraph prevents 90% of the disputes that destroy contractor-client relationships.

Include a contingency line

For renovation and remodel projects, include a 10-15% contingency allowance for unforeseen conditions. New construction might only need 5%. Be explicit: "Contingency (10%): $5,000 — covers unforeseen conditions discovered during demolition or construction. Unused contingency is not billed." Clients appreciate the honesty, and it prevents the awkward mid-project call asking for more money.
