True Cost Calculator
True Margin Calculator is a free web tool that shows roofing contractors the lowest price they can charge on a job and still make money.
Most roofers do not go out of business because of slow months. They go out because they underbid good work. Miscalculated waste and overhead cost the average roofer 3% to 5% of net profit on every job. Over a season, that is the difference between growing and just getting by.
The True Margin Calculator fixes the math. You enter your real numbers, and it gives you one clear figure: the "must-charge" price you need to hit to protect your margin on that specific job.
What it does: - Calculates your true minimum price per job, after waste and overhead are accounted for - Shows where your margin is leaking so you can fix your pricing - Helps you stop underbidding without pricing yourself out of jobs - Works on any device, with nothing to download, install, or sign up for
Who it is for: - Solo operators and small crews who handle their own estimating - Growing companies that want consistent, profitable bids across multiple estimators - Any roofing contractor tired of guessing whether a job will actually make money
Why trust it: The calculator comes from Roofing Software Guide, an independent, no-pay-to-play review platform for roofing software. It was founded by Matt Richardson, who spent 12 years running a roofing company and built the tool after watching capable contractors go broke over bad math. The same team publishes hands-on reviews, comparisons, and buyer's guides for the CRM, estimating, and measurement tools roofers use every day.
Completely free. No account, no email, no catch. Just enter your numbers and get your price.

True Margin Calculator's answer:
Most margin calculators are generic and assume your costs are already correct. This one is built for roofing contractors and includes the waste and overhead that roofers most often get wrong, usually 3% to 5% of net profit. It's free, no account needed, with no upsell. It exists to help you price jobs right, not to sell you anything.
True Margin Calculator's answer:
It's made for roofing, not generic job costing. Most calculators just apply a markup. This one looks at the two things that cost roofers the most profit, material waste and overhead, and tells you the lowest price you can charge on a job and still make money. It's free, there's no signup, and it comes from Roofing Software Guide, an independent review site run by people who have actually run a roofing crew.
True Margin Calculator's answer:
Roofing contractors of every size, from solo operators to multi-crew companies. It's most useful for owners who do their own estimating and want to be sure they aren't underpricing jobs or losing money on work they win.
True Margin Calculator's answer:
Roofing Software Guide was founded by Matt Richardson, who spent 12 years running a roofing company. He built the calculator after seeing too many good contractors go broke from bad math, underbidding jobs because they never fully accounted for waste and overhead. The tool takes that lesson and turns it into a few quick inputs that show the price you need to charge to stay profitable.
True Margin Calculator's answer:
It's a simple web-based tool. It runs in any modern browser with nothing to download or install. The math happens right on the page, so you can get your number in seconds from your phone on the jobsite or a computer in the office.
True Margin Calculator's answer:
It's a free tool, so it's used by independent roofing contractors all over the U.S. rather than a few big accounts. That ranges from one-truck operators to established multi-crew companies. The same contractors use Roofing Software Guide's independent reviews to pick their CRM, estimating, and measurement software.

This is why eval and observability ship as a unit, not as separate purchases. agent-eval scores and gates the output โ the tiers above, drift, hallucination. AgentLens captures the trace of how the agent got there: every model step and tool call, the resolved inputs, the raw outputs, the trajectory.
