Features and specs

What each product offers, as listed by its team.

True Margin Calculator 5 features
ShellNewHandler 0 features
  • 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.

Possible disadvantages

  • Limited scope
    As a single-purpose calculator, it only addresses margin calculations and doesn't offer broader business management or estimating features that a full software suite would provide.
  • Manual data entry
    Users must manually input their cost figures each time, and inaccurate inputs will lead to misleading results, requiring careful data preparation.
  • No integration
    The tool likely operates as a standalone calculator without integration into accounting, CRM, or job management systems, requiring duplicate data handling.
  • Requires cost knowledge
    To get meaningful results, users need to already understand and have accurate figures for their material, labor, and overhead costs, which may be a barrier for less experienced businesses.
  • Generic assumptions
    A simple calculator may not account for nuanced variables like regional pricing, seasonal fluctuations, or complex overhead allocations that affect true profitability.

Analysis

An editorial look at what each product does well and who it suits.

True Margin Calculator
ShellNewHandler

Overall verdict

  • True Margin Calculator appears to be a useful niche tool for roofing contractors who want to accurately calculate profit margins and markup on jobs, though as a product from a smaller niche site it lacks the widespread reviews or track record of major roofing software platforms, so due diligence is recommended before purchase.

Why this product is good

  • Focuses specifically on margin and markup calculations tailored to the roofing industry, addressing a common pain point where contractors underprice jobs
  • Likely simple and easy to use compared to full-scale roofing estimation suites, making it accessible for smaller contractors
  • Can help prevent common pricing mistakes by clearly separating markup from margin percentages
  • 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
  • Contractors who do not need a full estimating or CRM suite and just want a standalone margin calculator
  • Roofing sales reps who need to quickly verify job profitability in the field
  • Owners looking for a low-cost entry point before investing in more comprehensive roofing business software

Overall verdict

  • ShellNewHandler is a niche, lightweight utility hosted on SourceForge designed to give users more control over the Windows 'New' context menu (the ShellNew menu). It can be considered good for its specific narrow use case, but it is an older, minimally maintained tool that may not suit all users, especially those on modern Windows versions.

Why this product is good

  • Provides direct control over customizing the Windows right-click 'New' menu, allowing users to add or remove file type entries
  • Lightweight and free, without bundled bloatware typical of some other free utilities
  • Simple and focused in scope, making it easy to understand for its specific purpose
  • Open distribution via SourceForge allows transparency and no-cost access

Recommended for

  • Power users who want to declutter or customize the Windows New context menu
  • IT administrators managing standardized desktop environments across multiple machines
  • Users comfortable with older utility-style tools and Windows registry-related tweaks
  • Not recommended for casual users seeking modern, actively supported software with regular updates

Questions & Answers

As answered by people managing True Margin Calculator and ShellNewHandler.

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.

  • I recently got libreoffice, but now the new option in right click looks like a mess. Can someone help me get rid of them please?
    Use Shell New Handler. Run the portable app and simply untick the items you don't want to appear in your new context menu. Source: about 4 years ago
  • This menu should be easy to add/remove programs to... Who is really creating Access Databases from this menu often enough to keep it here? (Not me!) Is there an easy way to edit this?
    I've always used ShellNewHandler for this. It's a really simple portable utility that allows you to remove most of the items from that menu. Tested it out on Windows 11 and it's still compatible. Source: over 5 years ago
