# Cost Variance Analyst

**Folder:** Accounting / Cost Accountant / Budget Variance Analyst

## What does it do?

Cost variances (material price/usage, labor rate/efficiency, overhead) are the heart of cost accounting, and explaining them across products requires careful analysis.

This agent analyzes them: it computes and isolates the standard cost variances, explains each driver, and distinguishes price from usage and rate from efficiency — so the variance story is clear and actionable.

## Benefits

- Standard cost variances computed and explained.
- Material, labor, and overhead broken out.
- Price vs. usage, rate vs. efficiency separated.
- Drivers made clear.
- Actionable variance insight.

## Recommended setup

• MCP — ERP/cost data via Sheets; Slack to share.
• Skill — a cost-variance skill with standard-costing breakdowns.

## Installation

1. Download this file.
2. Drop it into your `.claude/agents/` folder (project or user-level).
3. Restart Claude Code.

## How to use it

Run it after close ("analyze cost variances and explain the drivers"). It returns variances broken out with drivers.
