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 features and specs

  • Accurate profit margin insight
    The True Margin Calculator is designed to help roofing contractors calculate their real profit margins rather than relying on simple markup, giving a clearer picture of actual profitability on each job.
  • Prevents underpricing
    By accounting for all costs and the difference between markup and margin, the tool helps contractors avoid the common mistake of underpricing jobs and losing money.
  • Easy to use
    The calculator provides a straightforward interface where users can input their costs and desired margins to quickly get pricing figures without complex spreadsheets.
  • Educational value
    It helps users understand the crucial distinction between margin and markup, improving their overall financial literacy and business decision-making.
  • Industry-specific focus
    Tailored to roofing businesses, the calculator addresses the specific pricing challenges and cost structures common in the roofing industry.

@imqueue features and specs

  • TypeScript-first design
    imqueue is built with TypeScript at its core, providing strong typing, better IDE support, and compile-time error checking, which helps catch bugs early and improves the developer experience when building microservices.
  • RPC-style messaging abstraction
    It simplifies inter-service communication by abstracting away the complexities of message queue protocols, allowing developers to make calls that feel like local function calls while the underlying complexity of message passing is handled by the framework.
  • Built on RabbitMQ
    By leveraging RabbitMQ as its message broker, imqueue benefits from a mature, battle-tested messaging system with reliable delivery guarantees, clustering support, and a large ecosystem of tools and documentation.
  • Code generation and tooling
    imqueue provides CLI tools and code generation capabilities that can automatically create service clients and boilerplate code, reducing repetitive work and helping maintain consistency across microservices.
  • Microservices-focused architecture
    The framework is specifically designed for building distributed microservices systems, offering features like service discovery and structured communication patterns that address common challenges in distributed system design.

Possible disadvantages of @imqueue

  • Smaller community and ecosystem
    Compared to more mainstream microservices frameworks, imqueue has a relatively small user base and community, which can mean fewer third-party resources, tutorials, Stack Overflow answers, and community-contributed plugins or extensions.
  • Limited documentation depth
    While basic documentation exists, some users report that advanced use cases, edge cases, and troubleshooting guides are not as thoroughly documented as more established frameworks, requiring more trial-and-error or direct code inspection.
  • RabbitMQ dependency lock-in
    Being tightly coupled to RabbitMQ means teams must adopt and manage this specific message broker, which could be a limitation for organizations that prefer or already use alternative messaging systems like Kafka, NATS, or AWS SQS.
  • Learning curve for framework-specific patterns
    Developers need to learn imqueue's specific conventions, decorators, and architectural patterns, which adds an additional learning curve on top of understanding TypeScript and general microservices concepts.
  • Potential scalability concerns for very large systems
    As with many queue-based RPC frameworks, extremely high-throughput or very large-scale distributed systems may encounter performance bottlenecks or require significant additional configuration and tuning of the underlying RabbitMQ infrastructure.

Analysis of True Margin Calculator

  • Affordable alternative to comprehensive roofing business software for contractors who only need pricing help
  • Published by a site dedicated to roofing software reviews and guides, suggesting some industry-specific expertise went into its design

Recommended for

  • Small to mid-sized roofing contractors who want a quick tool to ensure accurate profit margins
  • Business owners transitioning from guesswork pricing to formal margin-based pricing strategies

Questions & Answers

As answered by people managing True Margin Calculator and @imqueue.

Why should a person choose your product over its competitors?

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.

What makes your product unique?

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.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

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.

Who are some of the biggest customers of your product?

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.
