Earned Value (EV) is the budgeted value of work actually completed on a project to date, used to measure whether a project is ahead, behind, or on track against its schedule and budget. Earned Value Management (EVM) is the broader methodology that connects EV to Planned Value and Actual Cost, producing the full set of performance formulas project managers rely on to forecast outcomes. Every EVM formula — CPI, SPI, EAC, ETC, VAC — derives from these three core inputs.
Earned Value (EV) is the budgeted cost of work actually completed on a project as of a specific reporting date. EV converts physical progress into a dollar figure, allowing a project manager to compare completed work directly against both the schedule and the budget.
What Is Earned Value Management (EVM)?
Earned Value Management (EVM) is a project management methodology that objectively measures performance by integrating scope, schedule, and cost data through a project’s work breakdown structure. EVM does not rely on subjective status updates — every metric derives from measurable, budgeted values.
What Are the Core Earned Value Management Terms and Formulas?
EVM relies on three foundational inputs — Actual Cost, Planned Value, and Earned Value — from which every other EVM formula is calculated. Understanding each term’s formula and interpretation is required before any performance index or forecast can be applied correctly.
- Actual Cost (AC) — total money spent on the project to date. Direct input value, not calculated.
- Planned Value (PV) — budgeted cost of work scheduled to be complete by this date. Formula: Planned % Complete × BAC.
- Earned Value (EV) — budgeted cost of work actually completed to date. Formula: % Work Complete × BAC.
- Budget at Completion (BAC) — total approved budget for the entire project.
- Cost Performance Index (CPI) — cost efficiency ratio. Formula: EV / AC. CPI below 1 signals over budget; above 1 signals under budget.
- Schedule Performance Index (SPI) — schedule efficiency ratio. Formula: EV / PV. SPI below 1 signals behind schedule; above 1 signals ahead of schedule.
- Cost Variance (CV) — dollar amount over or under budget. Formula: EV − AC. Negative signals over budget.
- Schedule Variance (SV) — dollar amount ahead or behind schedule. Formula: EV − PV. Negative signals behind schedule.
- Estimate at Completion (EAC) — forecasted total project cost given current performance. Four formula variants apply depending on project conditions.
- Estimate to Complete (ETC) — forecasted cost of remaining work only. Formula: EAC − AC.
- Variance at Completion (VAC) — forecasted budget variance at project end. Formula: BAC − EAC.
How Do You Calculate Earned Value?
A project manager calculates Earned Value by multiplying the percentage of work actually completed by the project’s total approved budget.
A software implementation project has a total budget (BAC) of $400,000 and consists of 800 planned units of work. At the current reporting date, the team has completed 560 units.
Percent Complete = 560 / 800 = 70% EV = 70% × $400,000 EV = $280,000
The project has earned $280,000 in budgeted value based on the work actually completed, regardless of how much has actually been spent.
How Do You Interpret Earned Value Against Planned Value and Actual Cost?
Comparing EV to PV reveals schedule performance, while comparing EV to AC reveals cost performance — the two comparisons answer different questions and must be read separately. A project can be simultaneously ahead of schedule and over budget, or behind schedule and under budget; neither comparison implies the other.
- EV below PV — the project is behind schedule; less work has been completed than planned by this date.
- EV above PV — the project is ahead of schedule; more work has been completed than planned by this date.
- EV below AC — the project is over budget; more has been spent than the value of work completed.
- EV above AC — the project is under budget; less has been spent than the value of work completed.
How Do You Read an Earned Value Graph?
An Earned Value graph plots PV, EV, and AC as three lines against time, and the position of each line relative to the others communicates schedule and cost status at a glance. Stakeholders unfamiliar with EVM formulas can read project status directly from the graph without calculating a single index.
- EV line below the PV line indicates the project is behind schedule.
- EV line above the PV line indicates the project is ahead of schedule.
- AC line above the EV line indicates the project is over budget.
- AC line below the EV line indicates the project is under budget.
How Does Earned Value Connect to Other EVM Formulas?
Earned Value is the foundation input for every downstream EVM formula, including cost forecasting, schedule forecasting, and project selection metrics used earlier in a project’s lifecycle. Each of these formulas extends the same core EV, PV, and AC data into a specific decision-support calculation.
- PERT and three-point estimating generate the duration and cost inputs used to establish PV before a project begins.
- EAC forecasting uses EV, AC, and CPI to project total project cost once work is underway.
- Payback Period evaluates a project’s investment recovery timeline before EVM tracking begins.
- Return on Investment (ROI) evaluates overall project profitability alongside EVM cost data. See the full formula
- Parametric and analogous estimating establish the original BAC and PV figures that EVM tracks against throughout execution.
How Does Earned Value Appear on the PMP Exam?
The PMP exam tests Earned Value through both direct calculation questions and multi-metric interpretation scenarios that require reading CPI and SPI together rather than in isolation. Exam questions frequently supply five or more values at once and ask what they collectively indicate about project health.
Sample Question 1: A project has BAC = $500,000, PV = $310,000, EV = $290,000, and AC = $270,000. What does this data indicate about project performance? A) The project is ahead of schedule and over budget B) The project is behind schedule and under budget C) The project is ahead of schedule and under budget D) The project is behind schedule and over budget
Sample Question 2: A project manager calculates CPI = 1.08 and SPI = 0.91 for an active project. Which statement correctly interprets these figures? A) The project is spending efficiently but running behind schedule B) The project is over budget and ahead of schedule C) The project is on budget and on schedule D) The project is under budget and behind on cost efficiency
Sample Question 3: A project has EV = $150,000 and PV = $180,000. If this trend continues unchanged, what is the most likely outcome? A) The project will finish ahead of schedule B) The project will finish behind schedule C) The project will finish under budget D) The project will finish exactly on budget
Sample Question 4: A project has completed 45% of its total scope. The total approved budget is $220,000. What is the current Earned Value? A) $45,000 B) $99,000 C) $121,000 D) $220,000
Answers: 1) B — EV ($290,000) is below PV ($310,000), indicating the project is behind schedule; EV ($290,000) is above AC ($270,000), indicating the project is under budget. The project is behind schedule and under budget. 2) A — CPI above 1 indicates strong cost efficiency; SPI below 1 indicates the project is behind schedule. 3) B — EV below PV indicates the project is behind schedule, and this trend, if unchanged, results in finishing behind schedule. 4) B — EV = 45% × $220,000 = $99,000.
Frequently Asked Questions
What Is the Difference Between Earned Value and Planned Value?
Earned Value measures the budgeted cost of work actually completed, while Planned Value measures the budgeted cost of work that was scheduled to be completed by the same date. Comparing the two reveals whether the project is ahead of, behind, or exactly on its planned schedule.
Is Earned Value the Same as Earned Value Management?
Earned Value is a single metric, while Earned Value Management is the complete methodology that uses Earned Value alongside Planned Value and Actual Cost to produce a full set of performance and forecasting formulas. EV is one input within the larger EVM system, not a substitute for it.
How Often Should Earned Value Be Calculated During a Project?
Earned Value should be calculated at a fixed, recurring interval — weekly, biweekly, or monthly — established during project planning rather than left ad hoc. Waiting until late in the project to calculate EV eliminates the early-warning benefit the metric is designed to provide.
Do You Need Special Software to Calculate Earned Value?
Earned Value does not require specialized software — the core formula runs on basic percentage-complete and budget data available in a spreadsheet. Larger organizations often use dedicated EVM software for automation and reporting at scale, but the underlying calculation remains simple arithmetic.
