Earned Value Management (EVM) โ Smart Financial Analysis
Track project performance by comparing planned costs, actual costs, and earned value. Assess budget and schedule status with SV, CV, SPI, CPI, and EAC.
Why This Matters for Your Finances
Why: Planned Value (PV) = budgeted cost of work scheduled. Earned Value (EV) = budgeted cost of work completed. Actual Cost (AC) = actual cost incurred. Schedule Variance SV = EV - P...
How: Enter Planned Value (PV) ($), Actual Cost (AC) ($), Earned Value (EV) ($) to get instant results. Try the preset examples to see how different scenarios affect the outcome, then adjust to match your situation.
- โPlanned Value (PV) = budgeted cost of work scheduled.
- โEAC predicts the total final cost of the project.
- โIn Agile, story points often serve as the basis for earned value.

๐ก Money Facts
Earned Value Management (EVM) analysis is used by millions of people worldwide to make better financial decisions.
โ Industry Data
Financial literacy can increase household wealth by up to 25% over a lifetime.
โ NBER Research
The average American makes 35,000 financial decisions per yearโmany can be optimized with calculators.
โ Cornell University
Globally, only 33% of adults are financially literate, making tools like this essential.
โ S&P Global
Earned Value Management is the Pentagon's favorite project control toolโit predicted the F-35 cost overrun years before official estimates. EVM uses three data points (PV, EV, AC) to answer: Are we ahead or behind schedule? Are we over or under budget? What will the project ultimately cost? NASA, DoD, and major contractors use EVM on every project over $20M.
Key EVM Terminology
Understanding the three core measurements is essential. Unlike traditional tracking that only compares planned vs. actual spend, EVM adds the dimension of work completed.
Planned Value (PV)
Budgeted cost of work scheduled by a given date. Established in the project baseline during planning.
Earned Value (EV)
Budgeted cost of work actually completed. Measures value delivered regardless of actual spend.
Actual Cost (AC)
Total cost incurred for work completed to date. Includes labor, materials, equipment, overhead.
Budget at Completion (BAC)
Total planned value for the complete project. The sum of all PV at project completion.
Variance Formulas
Variances are expressed in dollars. Positive is favorable; negative indicates problems.
SV = EV - PV
Positive = ahead of schedule (earned more than planned). Negative = behind schedule (earned less than planned).
CV = EV - AC
Positive = under budget (spent less than value earned). Negative = over budget (spent more than value earned).
VAC = BAC - EAC
Projected budget surplus or deficit at completion. Positive VAC = will finish under budget.
Performance Indices
Indices are ratios. Values above 1.0 indicate good performance; below 1.0 indicate problems.
SPI = EV / PV โ Schedule efficiency. >1 = ahead of schedule, <1 = behind schedule.
CPI = EV / AC โ Cost efficiency. >1 = under budget, <1 = over budget. Most reliable early indicator.
TCPI = (BAC - EV) / (BAC - AC) โ Efficiency needed on remaining work to stay within budget. TCPI > 1 means you must improve to hit budget.
Estimate at Completion (EAC)
EAC predicts the total final cost. The CPI method (EAC = BAC / CPI) assumes current cost performance will continue for the remainder of the project.
EAC above BAC indicates projected overrun; below BAC indicates projected underrun. EAC forecasts become more reliable after 15-20% of the project is complete.
When to Use EVM
EVM is ideal for large-scale projects, government contracts, fixed-budget projects, and time-critical deliverables. DoD requires EVM on contracts over $20M.
Government & Defense
NASA, DoD, and many agencies mandate EVM for accountability and transparency.
Construction & Engineering
Large infrastructure projects use EVM to track phases and manage cost overruns.
The S-Curve
PV, EV, and AC plotted over time form the classic EVM S-curve. PV is the baseline; EV shows actual progress; AC shows actual spending. Gaps between them reveal schedule and cost performance.
When EV is below PV, you are behind schedule. When AC is above EV, you are over budget. The S-curve visualization makes trends immediately visible to stakeholders.
EVM in Agile
Story points map to earned value. Completed story points contribute to EV. Feature completion percentages can also drive EV calculations in sprints.
Agile-EVM hybrid approaches assign dollar values to story points based on budget allocation. As sprints complete, EV accumulates, enabling CPI and SPI tracking alongside velocity.
EVM Limitations
EVM requires a detailed baseline, disciplined progress tracking, and can be resource-intensive. SPI converges to 1.0 near completion. Quality is not directly measured.
- Requires significant upfront planning and a stable baseline
- Progress measurement can be subjective (percent complete)
- Does not measure deliverable quality
- SPI loses meaning as project nears completion

| SPI | ext{EV} / ext{PV} | SPI > 1 | SPI < 1 |
| EAC | ext{BAC} / ext{CPI} | EAC < BAC | EAC > BAC |
| VAC | ext{BAC} - ext{EAC} | VAC > 0 | VAC < 0 |
| TCPI | rac{ ext{BAC}- ext{EV}}{ ext{BAC}- ext{AC}} | TCPI < 1 | TCPI > 1 |
How to Interpret Your Results
Healthy Project
CPI > 1 and SPI > 1. You are under budget and ahead of schedule. EAC < BAC. Project is on track for success.
At Risk
CPI or SPI < 1. One dimension is trending poorly. Early corrective action can prevent escalation.
Troubled
CPI < 1 and SPI < 1. Over budget and behind schedule. EAC > BAC. Requires recovery plan.
TCPI Warning
TCPI > 1 means you must improve efficiency on remaining work to stay within budget. TCPI > 1.2 is very challenging.
EVM by Industry
Estimate to Complete (ETC) and Variance at Completion (VAC)
ETC = EAC - AC
The remaining budget needed to complete the project. If EAC is $12M and you have spent $5M (AC), ETC = $7M. This is the amount you expect to spend from now until completion.
VAC = BAC - EAC
The projected budget surplus or deficit. Positive VAC = will finish under budget. Negative VAC = will exceed budget. VAC tells you how much you need to recover or how much cushion you have.
EVM Best Practices
- Establish a detailed work breakdown structure (WBS) before starting. PV and EV depend on it.
- Use objective progress measurement (e.g., 0/50/100, or weighted milestones) rather than subjective percent complete.
- Review EVM metrics at least monthly; weekly for high-risk or fast-moving projects.
- When CPI or SPI drops below 0.95, investigate immediately. Early intervention is key.
- Track trends, not just point-in-time values. A declining CPI over three periods is a strong warning.
- Combine EVM with risk management. Use VAC and EAC to trigger risk response plans.
