Result Interpretation

Project Earned Value Cost Performance Index (CPI) Calculator computes Cost Performance Index in dimensionless using the defined engineering formula and the input values provided. Cost Performance Index is expressed in dimensionless. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Earned Value = 15000
  • Actual Cost = 12000

Expected Result:

  • Cost Performance Index = 1.25

Engineering Interpretation:

Under the given input conditions, the calculated result is: Cost Performance Index = 1.25 dimensionless.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.

Formula / Method

cost performance index = earned value / actual cost
