Establishes what something actually costs — fixed, variable and mixed cost behavior, absorption versus variable costing, job-order, process and activity-based methods, breakeven and operating leverage, and price/volume/mix decomposition. Use this to set a price floor, explain why revenue or margin moved, decide make versus buy, judge whether a product line earns its place, or work out how an allocation basis is distorting a reported margin.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Cost accounting Most bad pricing decisions, bad product-line decisions, and bad margin arguments come from the same place: nobody agrees what the thing costs. ## Classify cost behavior before you allocate anything - **Fixed** costs do not move with volume — within a relevant range. Outside that range they step, and the step is usually large: another shift, another facility, another tier of licensing. - **Variable** costs move with each unit: materials, payment processing, per-unit fulfillment, usage-based infrastructure. - **Mixed** costs have both, and most real accounts are mixed. Split them with high-low or a regression on historical volume rather than guessing the proportion. The split is not academic. Variable cost sets the floor for one more incremental order. Fully loaded cost sets the floor for the business as a whole. Confusing the two is how companies price themselves into volume that loses money. ## Know which costing basis you are looking at **Absorption costing** puts fixed production overhead into inventory and releases it when the unit sells. **Variable costing** expenses that overhead as incurred. …

How to install
mdr add cbrock84/headcount/cost-accounting@sha256:88feb85ae659d895The line at the top of this page pins the label git:20260916.e72e404, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
