EVM Calculator
Free online EVM calculator to measure key earned value management metrics from planned value, earned value, and actual cost. This calculator is useful for project managers, PMO teams, finance controllers, construction planners, software delivery leads, students, and business analysts who want a simple way to see whether a project is ahead or behind schedule and under or over budget. EVM stands for earned value management, and it is one of the most widely used project control methods because it combines scope, schedule, and cost performance into one framework.
The calculator works with three core inputs. Planned value, often called PV, is the budgeted value of work that should have been completed by this point. Earned value, often called EV, is the budgeted value of work actually completed. Actual cost, often called AC, is the real cost spent to complete that work. From these values, the calculator shows cost variance, schedule variance, cost performance index, and schedule performance index. These results help reveal whether the project is overspending, underspending, ahead of plan, or behind plan.
The formula of earned value management
Cost variance (CV) = Earned value – Actual cost
Schedule variance (SV) = Earned value – Planned value
Cost performance index (CPI) = Earned value / Actual cost
Schedule performance index (SPI) = Earned value / Planned value
Here planned value means the budgeted value of scheduled work, earned value means the budgeted value of completed work, and actual cost means the real cost incurred. A positive cost variance is favorable because the project earned more value than it spent. A negative cost variance is unfavorable because the project spent more than the value earned. A positive schedule variance means the project is ahead of plan, while a negative schedule variance means it is behind plan.
Solved Example
Example 1: Find the EVM metrics if planned value is $100,000, earned value is $92,000, and actual cost is $98,000.
Solve: Cost variance = 92000 – 98000 = -$6,000
Schedule variance = 92000 – 100000 = -$8,000
Cost performance index = 92000 / 98000 = 0.939
Schedule performance index = 92000 / 100000 = 0.920
Example 2: Find the result if planned value is $150,000, earned value is $162,000, and actual cost is $155,000.
Solve: Cost variance = 162000 – 155000 = $7,000
Schedule variance = 162000 – 150000 = $12,000
Cost performance index = 162000 / 155000 = 1.045
Schedule performance index = 162000 / 150000 = 1.080
Example 3: Find the result if planned value is $80,000, earned value is $70,000, and actual cost is $76,000.
Solve: Cost variance = 70000 – 76000 = -$6,000
Schedule variance = 70000 – 80000 = -$10,000
Cost performance index = 70000 / 76000 = 0.921
Schedule performance index = 70000 / 80000 = 0.875

How to use this EVM calculator
Enter planned value in the proper input field. After that, enter earned value and actual cost for the same project status date. Then click the calculate button. The calculator will show cost variance, schedule variance, cost performance index, and schedule performance index in the result box. Make sure all three values are measured for the same project, the same reporting date, and the same budget basis so the results stay meaningful.
This calculator is useful for project status reviews, monthly control reporting, construction cost tracking, software delivery monitoring, and executive summary dashboards. If cost variance is negative or CPI is below 1.00, the project may be over budget. If schedule variance is negative or SPI is below 1.00, the project may be behind schedule. When both indices rise above 1.00, the project is generally performing better than plan on those dimensions. Looking at both variance and index measures together helps make performance easier to interpret.
When using the result, remember that earned value analysis depends on realistic baseline planning and disciplined progress measurement. If planned value is weak or earned value is measured inconsistently, the output can look precise while still being misleading. Even so, EVM remains one of the most useful quick frameworks for project control. This calculator gives a fast numerical view that supports status reporting, variance review, forecast discussion, and practical project decision-making.
