Built for Utility, Not Extraction.

MetricRig isn't a venture-backed startup chasing growth at all costs. It's a personal project built by a single developer who got tired of bad calculators.

Privacy is the Architecture

Other tools ask for your email before showing results. MetricRig deliberately runs entirely in your browser. Your freight manifests, payroll data, and burn rates never leave your device. There is no database. There is no login. What happens on your rig, stays on your rig.

Engineered, Not Just Estimated

Most "calculators" are simple forms. MetricRig tools like the Container Loader use real physics engines and collision detection. The finance tools track cumulative compounding month-over-month. We don't just multiply two numbers; we simulate the scenario.

Zero Latency

By using WebWorkers and WebAssembly, MetricRig delivers desktop-class performance in a browser tab. You get instant feedback as you drag sliders or resize boxes. No server round-trips. No loading spinners. Just raw speed.

Free Forever

This project is supported by non-intrusive ads, allowing it to remain free used by students, founders, and logistics managers worldwide. No paywalls for "Pro" features. Every tool is full-featured from day one.

"I built MetricRig because I needed a place to do 'napkin math' without opening a spreadsheet or signing up for a trial. I hope these tools help you build, ship, and grow whatever you're working on."

Common Questions

You ask, we answer.

Everything you need to know about the platform.

Yes. MetricRig is 100% free to use. There are no paywalls, no 'Pro' plans, and no limits on how many calculations you can run. The platform is supported by display advertising, which allows us to pay for server costs while keeping the tools accessible to everyone.
The 3D Container Loader uses a tailored bin-packing algorithm that accounts for physical dimensions, stacking logic, and orientation constraints. While it provides a highly accurate estimation of what fits, real-world loading factors (like pallet overhang, box deformation, and manual loading inefficiencies) can vary. We recommend using the tool for planning and estimation, but always leaving a 5-10% safety margin.
No. We do not store your data because we don't even see it. MetricRig runs entirely on your device (Client-Side). When you enter payroll data, freight manifests, or financial metrics, that information stays in your browser's memory. It is never transmitted to our servers or saved in a database.
Absolutely. MetricRig is actively developed based on user feedback. If you need a specific tool for logistics, SaaS finance, or digital marketing, you can reach out via the Contact page. Many of our current tools (like the Split Test Calculator and Cap Rate Tool) started as user requests.
We obsess over performance. MetricRig uses modern web technologies like React, Vite, and WebWorkers to deliver a native-app feel. We also minimize external scripts and optimize assets aggressively. This isn't just for user experience—it's to ensure the tools work reliably even on slow warehouse wifi connections.
Yes. Many of our users are logistics managers, CFOs, and marketing directors at established companies who use MetricRig for quick, professional-grade estimates. The calculations use standard industry formulas (GAAP for finance, NMFC for freight). However, for mission-critical audit-level work, we always recommend verifying with your internal systems.
Zero-Knowledge Architecture

Your data never leaves
your browser.

MetricRig runs entirely client-side using WebAssembly. We do not store your freight manifests, payroll data, or burn rates on our servers. What happens on your rig, stays on your rig.

USPS Dimensional Weight Divisor 2026

The USPS dimensional weight divisor commonly used for retail-style parcel calculations is 166 for many domestic pricing scenarios involving larger, lightweight packages. That means you multiply length x width x height in inches, divide by 166, and compare that result to actual scale weight. If the dimensional weight is higher, that becomes the billable weight. For sellers shipping bulky but light cartons, knowing the divisor immediately helps prevent underpricing orders and margin erosion.

Pick and Pack Cost Per Order: 2026 Benchmarks and Drivers

In-house pick and pack costs in 2026 range from $2.50 to $5.50 per single-item order, rising to $4.50–$9.00 for multi-item orders with custom packaging or kitting requirements. Third-party logistics (3PL) providers typically charge $2.75–$7.00 per order for pick and pack, plus receiving, storage, and materials fees that add $1.50–$3.00 on top. Labor accounts for 55–70% of total fulfillment cost, making pick rate per hour the most critical operational variable — the industry average pick rate runs 80–120 units per hour for manual picking.
