Earned Value Management (EVM) Calculator

Take full control of your projects with an all-in-one earned value toolkit that turns complex data into clear insights. Enter PV, EV, and AC to reveal real-time performance metrics. Instantly visualize CPI, SPI, and variances, choose your preferred EAC forecasting method, and export results as CSV or PDF.

Interpretation: CPI > 1 means under budget; SPI > 1 means ahead of schedule. TCPI > 1 indicates required future efficiency above current baseline.

Formulas Used

  • CPI = EV / AC
  • SPI = EV / PV
  • CV = EV − AC
  • SV = EV − PV
  • VAC = BAC − EAC
  • EAC methods:
    • Planned rate: EAC = AC + (BAC − EV)
    • CPI only: EAC = BAC / CPI
    • CPI×SPI: EAC = AC + (BAC − EV) / (CPI × SPI)
    • Manual: user-entered forecast
  • ETC = EAC − AC
  • TCPI to BAC = (BAC − EV) / (BAC − AC)
  • TCPI to EAC = (EAC − EV) / (EAC − AC)
Notes: Ratios are undefined when denominators are zero. Choose an EAC method consistent with your situation (typical performance, atypical conditions, or external replanning).

How to Use

  1. Enter BAC and pick an EAC method that fits your forecasting scenario.
  2. Populate the timeline rows with PV, EV, and AC for each period; add rows as needed.
  3. Click Compute to update totals, indices, and forecast.
  4. Review CPI/SPI and CV/SV; use the chart to compare PV, EV, and AC trends.
  5. Export your data via CSV or PDF for reporting to stakeholders.

FAQs

If current performance is expected to continue, BAC/CPI is common. If you expect recovery toward plan, AC + (BAC − EV) may fit. When schedule efficiency affects cost, use AC + (BAC − EV)/(CPI×SPI).

CPI > 1 means spending less than planned for earned work (good). SPI > 1 means accomplishing more work than planned by this date (good). Values below 1 indicate variances requiring attention.

Enter period values for PV, EV, and AC per row. The calculator builds cumulative curves automatically for the chart and totals.

Ratios with zero denominators are undefined. The tool shows “n/a” in that case. Ensure AC and PV are positive before interpreting CPI and SPI.

Yes. Use CSV for raw data. The PDF export includes a summary table and embeds the chart snapshot for a compact report.
