FAQs

How is Earned Value Management calculated?

This is a project-control metric and not a completion forecast.

Use Cases

Monitor project performance

Use the calculator to quickly assess whether your project is on schedule and on budget by computing variances and performance indices from PV, EV, and AC.

Example: If PV=100, EV=90, AC=110, then SV=-10, CV=-20, SPI=0.9, CPI=0.82.

Forecast project outcomes

The performance indices can be used to estimate future project performance and inform management decisions, such as whether corrective action is needed.

Example: A CPI of 0.8 suggests you are over budget and may need to adjust spending.

Frequently Asked Questions

What inputs do I need for the earned value management calculator?
You need three values: Planned Value (PV), Earned Value (EV), and Actual Cost (AC). PV is the budgeted cost for work scheduled, EV is the budgeted cost for work actually performed, and AC is the actual cost incurred for the work performed.
What does the calculator compute?
It computes Schedule Variance (SV = EV - PV), Cost Variance (CV = EV - AC), Schedule Performance Index (SPI = EV / PV), and Cost Performance Index (CPI = EV / AC). These metrics help assess project health.
How do I interpret the results?
Positive SV and CV indicate ahead of schedule and under budget, respectively. SPI > 1 means ahead of schedule, CPI > 1 means under budget. Negative values or indices less than 1 indicate unfavorable performance.

Tips & Common Mistakes

Tips

  • Ensure all three inputs (PV, EV, AC) are in the same currency and unit to get accurate results.
  • Use consistent time periods: PV, EV, and AC should all be measured as of the same date.
  • Regularly update EV and AC to reflect actual progress and costs for meaningful tracking.
  • Use the results to identify trends over time, not just a single snapshot.

Common Mistakes to Avoid

  • Using budgeted cost for work scheduled (PV) instead of earned value (EV) for schedule variance calculations.
  • Forgetting to include all actual costs in AC, leading to an inaccurate cost variance.
  • Interpreting indices without considering the project phase; early in a project, small variances may be normal.
