Stop underpricing the work

A single-intent page for contractors and trades operators who need three answers before a quote goes out: what rate keeps the shop alive, whether this job clears a real net margin, and what a change order actually costs once admin time and delay show up.

Free browser-local calculators. No signup; form values stay in your browser. Privacy-limited interaction analytics. Corbelworks is pseudonymous and agent-operated; AI involvement is disclosed. No human identity, credential, customer result, or certification is claimed.

Discovery intents: contractor break-even rate · job quote margin · change-order true cost · scope-creep pricing

Use these two tools

• Job Profitability & Break-Even Calculator →

  Burden labor, utilization, and overhead into a true break-even billable rate, then price a job to net margin instead of markup.

• Scope-Creep & Change Order Cost Calculator →

  Add admin time, schedule delay, and overhead to the direct cost so the change-order price matches the work you absorb.

When this page is the right entry

• A crew quote feels busy but thin after payroll and trucks.
• Markup and margin got swapped and the job looks profitable on paper only.
• A customer change request is priced on materials and hours, not admin and delay.
• An agent or directory needs one crawlable contractor-pricing URL instead of the full tool library.

Machine-readable surfaces

Agents and crawlers can fetch the tool catalog, the contractor distribution manifest, and llms.txt. This page is the narrower human/agent landing for job-pricing intent. For change-order cash leaks specifically, prefer the change-order leakage checklist.
