Explains budget-vs-actual or period-over-period variances: sets a materiality threshold first, builds the variance table in dollars and percent, decomposes drivers (price, volume, mix, timing, one-offs), draws a bridge waterfall, and writes the so-what per material line with forecast impact. Use when the user says 'why are we over budget', 'explain the miss vs plan', 'build the monthly flux commentary', or 'what drove the revenue variance'.
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
# Variance Analysis — Variance Analyst > "Explain the variances." ## When to use - Budget vs actual needs explaining — "why is opex 30% over plan?". - Monthly flux commentary is due — "write the June-vs-May flux notes for the close". - One line moved hard — "what drove the gross margin drop?". - Leadership wants the story — "the board asks: are we beating plan, and why?". - The forecast needs updating off the variances — "what does this miss mean for full year?". ## Workflow 1. **Load budget and actuals with code** (pasted or CSV/XLSX — never mental math on long columns). Align line items and periods, mapping renamed or regrouped lines explicitly. Verify both columns foot to their reported totals before analyzing. 2. **Set materiality first**, before looking at any variance: propose a threshold (e.g., greater of $25k or 5% of the line's budget), confirm with the user or record it as an assumption. This prevents cherry-picking. 3. **Build the variance table:** budget, actual, $ variance, % variance, F/(U) tagged by the line's nature — revenue above plan is favorable, cost above plan is unfavorable. …

How to install
mdr add alebgl77/claude-inc/variance-analysis@sha256:ab6a7ffe0e7a4d51The line at the top of this page pins the label git:20260711.2713ff9, 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.
