# EVM Calculator ## Overview The EVM Calculator skill provides comprehensive automated calculation of all Earned Value Management metrics, indices, and forecasts. It supports PMI PMBOK and ANSI/EIA-748 compliant calculations for project cost and schedule performance measurement and forecasting. ## Capabilities ### Core EVM Metrics - Calculate Planned Value (PV/BCWS) - Calculate Earned Value (EV/BCWP) - Calculate Actual Cost (AC/ACWP) - Calculate Schedule Variance (SV) and Cost Variance (CV) - Calculate SV% and CV% for normalized comparison ### Performance Indices - Calculate Schedule Performance Index (SPI) - Calculate Cost Performance Index (CPI) - Calculate Critical Ratio (CR = SPI x CPI) - Calculate TCPI (To-Complete Performance Index) - Support both BAC-based and EAC-based TCPI ### Forecasting - Calculate EAC using multiple methods: - EAC = BAC / CPI (typical performance) - EAC = AC + (BAC - EV) (atypical performance) - EAC = AC + [(BAC - EV) / (SPI x CPI)] (combined) - EAC = Bottom-up re-estimate - Calculate ETC (Estimate to Complete) - Calculate VAC (Variance at Completion) ### Visualization and Trending - Generate S-curve visualizations - Perform trend analysis on indices -

Where does this skill come from?
From a5c-ai/babysitter, a repository with 1,642 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
