About EVM Calculator
What is Earned Value Management (EVM)?
Earned Value Management (EVM) is a project management methodology that integrates scope, schedule, and cost to objectively measure project performance and progress. It provides early warning signals of cost and schedule problems.
Core EVM Inputs
| Input | Name | Description |
|---|---|---|
| BAC | Budget at Completion | Total planned budget for the project |
| PV | Planned Value | Budgeted cost of work scheduled to date |
| EV | Earned Value | Budgeted cost of work actually performed |
| AC | Actual Cost | Actual cost incurred for work performed |
Key EVM Formulas
Performance Indices
Cost Performance Index (CPI)
CPI = EV / AC
- CPI > 1: Under budget
- CPI = 1: On budget
- CPI < 1: Over budget
Schedule Performance Index (SPI)
SPI = EV / PV
- SPI > 1: Ahead of schedule
- SPI = 1: On schedule
- SPI < 1: Behind schedule
Variances
Cost Variance (CV)
CV = EV - AC
- CV > 0: Under budget
- CV < 0: Over budget
Schedule Variance (SV)
SV = EV - PV
- SV > 0: Ahead of schedule
- SV < 0: Behind schedule
Forecasting
Estimate at Completion (EAC)
EAC = BAC / CPI
Predicts total project cost based on current performance.
Estimate to Complete (ETC)
ETC = EAC - AC
Estimated cost to finish remaining work.
Variance at Completion (VAC)
VAC = BAC - EAC
Expected cost variance at project end.
To Complete Performance Index (TCPI)
TCPI = (BAC - EV) / (BAC - AC)
CPI needed on remaining work to meet BAC.
How to Use This Calculator

EVM Performance Categories
| Status | CPI & SPI Range | Description |
|---|---|---|
| Excellent | Both ≥ 1.1 | Under budget and ahead of schedule |
| Good | Both 1.0 - 1.1 | On track with minor variations |
| At Risk | Either 0.9 - 1.0 | Minor cost or schedule concerns |
| Critical | Either < 0.9 | Significant overrun or delay |
Frequently Asked Questions
When should I use EVM?
EVM is most valuable for large, complex projects where cost and schedule tracking are critical. It's widely used in construction, defense, IT, and engineering projects.
What does a CPI of 0.8 mean?
A CPI of 0.8 means for every $1 spent, you're only getting $0.80 of planned work done. This indicates a 20% cost overrun.
How accurate is EAC?
EAC accuracy depends on the assumption that current performance trends will continue. For volatile projects, consider using multiple EAC formulas.
Note: This calculator provides estimates for project analysis and planning. Actual project outcomes may vary based on changing conditions and risk factors.
Quick Reference
✅ Healthy Indicators
- • CPI ≥ 1.0 (On/Under budget)
- • SPI ≥ 1.0 (On/Ahead of schedule)
- • CV ≥ 0 (Positive cost variance)
- • SV ≥ 0 (Positive schedule variance)
⚠️ Warning Signs
- • CPI < 0.9 (Significant cost overrun)
- • SPI < 0.9 (Significant delay)
- • TCPI > 1.1 (Recovery may be difficult)
- • Declining trends in indices
