Precision tools for logistics, finance, and marketing — built by someone who needed them.
Last reviewed: February 2026
"Complex business mathematics should be accessible, instant, and private."
MetricRig was created by The MetricRig Dev — an independent developer and operations specialist based in British Columbia, Canada. With a background spanning logistics coordination, inventory management, and small business operations, the same frustration kept coming up: the calculations that matter most were either buried in expensive enterprise software or trapped in error-prone spreadsheets shared over email.
The 3D Container Loader came from hours wasted on manual load planning. The Freight Class calculator came from NMFC classification errors causing costly re-billing surprises. The Burn Rate and Unit Economics tools exist because founders deserve clarity without a consultant's invoice attached to it. Every tool on this platform solves a real problem that was personally experienced.
Carrier divisors, LTL surcharge thresholds, and freight class breakpoints change regularly. MetricRig's calculators and answer pages are reviewed at minimum annually — and immediately when major carriers (UPS, FedEx, USPS, DHL) publish rate updates. All logistics formulas reference published carrier rate guides. Finance formulas reference well-established industry benchmarks. If you spot an outdated number, the Contact page reaches the developer directly.
Not just a policy — it's how the code is written. MetricRig has no server-side database for user input. When you calculate payroll or freight costs, the math runs 100% in your browser. Your data never leaves your device because there is no server to send it to.
WebWorkers and client-side processing eliminate the loading spinner. Sliders update charts in real time. 3D scenes render at 60fps. The goal is a native app experience in a browser — because slow tools cost you time.
MetricRig is not a set-and-forget project. Carrier rates, industry formulas, and regulatory thresholds are monitored and updated. Every answer page displays when it was last reviewed so you always know how fresh the information is.
There's no support ticket queue here. The Contact page reaches the developer directly. If a calculation is wrong, a rate is outdated, or you have a tool request — it gets read by the person who built the platform.
Utility should come before monetization. MetricRig is supported by non-intrusive display advertising, which covers hosting and ongoing development costs while keeping every tool completely free. There are no "Pro" tiers, no feature gates, and no trial periods. A logistics manager at a small warehouse deserves the same tools as someone at a Fortune 500 company.
"Professional tools should be instant, reliable, and respectful of your data."

VNA systems create high point loads. Standard 600psf floors may need reinforcement.
Yes. UPS maximum size is 165 inches (Length + 2Width + 2Height). Exceeding triggers Large Package Surcharge or rejection.
96 inches is the most common LTL pallet height limit (including pallet). FedEx Freight and UPS Freight allow 94 inches. ABF allows 102 inches.
<12 Months is the gold standard for high-growth SaaS. If your payback is >18 months in 2026, investors view your growth as 'inefficient' due to high cost of capital.
To pass the Rule of 40 with 30% YoY growth, you need at least a 10% profit margin. Formula: Growth(30) + Profit(10) = 40.
Low margin dropshipping (15%) requires a very high ROAS of 6.67x to break even (1 / 0.15). This makes paid ads difficult to scale.
