Overview
The Earned Value Curves report plots three core EVM metrics over your project timeline as S-curves — Budget (BCWS), Earned Value (BCWP), and Actual Cost (ACWP). The shape and relative position of these curves tells you at a glance whether you are ahead of or behind schedule and whether you are over or under budget. Below the chart, a summary grid shows the key performance metrics for the previous cumulative, current period, and current cumulative positions.Prerequisites
- Select a project from the project selector.
- Select a reporting period from the reporting period selector. The chart and summary grid do not load until both filters are set.
Reading the Chart
The chart plots three spline curves over your project timeline:| Curve | EVM Term | What It Means |
|---|---|---|
| Budget | BCWS — Budgeted Cost of Work Scheduled | The planned value of all work scheduled through each period |
| Earned Value | BCWP — Budgeted Cost of Work Performed | The planned value of work actually completed through each period |
| Actual Cost | ACWP — Actual Cost of Work Performed | What the completed work actually cost through each period |
- If the Earned Value curve is below the Budget curve, the project is behind schedule (negative Schedule Variance).
- If the Actual Cost curve is above the Earned Value curve, the project is over budget (negative Cost Variance).
Summary Grid
Below the chart, a summary grid shows the following metrics for the previous cumulative, current period, and current cumulative positions:| Metric | Definition |
|---|---|
| SV | Schedule Variance = BCWP − BCWS. Negative = behind schedule. |
| CV | Cost Variance = BCWP − ACWP. Negative = over budget. |
| SPI | Schedule Performance Index = BCWP ÷ BCWS. Below 1.0 = behind schedule. |
| CPI | Cost Performance Index = BCWP ÷ ACWP. Below 1.0 = over budget. |
| BAC | Budget at Completion — the total approved budget for the project. |
| EAC | Estimate at Completion — auto-calculated as ACWP + (BAC − BCWP) ÷ CPI. |
| VAC | Variance at Completion = BAC − EAC. Negative means the project is forecast to finish over budget. |

When to Use This Report
Use EV Curves at the start of any status review to establish the overall performance picture before diving into the CPR detail. The S-curve immediately reveals whether performance is improving or degrading over time — something a tabular report alone cannot show.Exporting
