Terms of Use
By using ContractorMargin.com you agree to these simple terms. Read them — they're short.
Estimating tool — not financial advice
The calculators on ContractorMargin.com produce estimates based on the numbers you enter and published 2026 industry benchmark ranges. They are not a substitute for actual job costing, accounting software, tax advice, legal advice, or financial planning. Always verify your numbers against your own historical job data before submitting a bid or making a business decision.
No warranty
The site is provided "as is" without any warranty of accuracy, completeness, fitness for a particular purpose, or availability. We do our best to keep the benchmarks current and the math correct, but mistakes happen. If you find one, tell us.
Limitation of liability
ContractorMargin.com, its operators, and contributors are not liable for any loss, damage, missed margin, lost bid, or business decision you make based on the output of these tools. You use the site at your own risk.
Acceptable use
Don't try to take the site down, scrape it at high volume, or embed the calculators into a commercial product without permission. Personal, contractor, and small-business use is always welcome and encouraged.
Intellectual property
The calculator logic, benchmark data compilation, copy, and site design are owned by the operators of ContractorMargin.com. Screenshots and fair-use quotation in educational or editorial contexts are fine.
Jurisdiction
These terms are governed by the laws of the Commonwealth of Massachusetts, United States.
Changes
We may update these terms from time to time. Continued use after changes means you accept the revised version.
