Earned Value Management Calculator
Calculate CPI, SPI, EAC and TCPI from project totals in your browser.
A QUICK WALKTHROUGH
How to use this tool
- Enter the four totals, then calculate.
- EAC = BAC / CPI assumes the current cost efficiency continues. TCPI = (BAC − EV) / (BAC − AC) targets the original budget. No business decision or financial advice is provided.
Formula and assumptions
CPI = EV / AC; SPI = EV / PV; EAC = BAC / CPI; TCPI = (BAC − EV) / (BAC − AC); CV = EV − AC; SV = EV − PV; ETC = EAC − AC; VAC = BAC − EAC EAC = BAC / CPI assumes the current cost efficiency continues. TCPI = (BAC − EV) / (BAC − AC) targets the original budget. No business decision or financial advice is provided.
Limits and privacy
Use one currency and the same reporting date. BAC must be greater than 0; PV, EV and AC must be nonnegative finite numbers up to 1,000,000,000,000. PV and EV cannot exceed BAC. An undefined ratio or nonfinite result is shown as unavailable: CPI needs AC > 0; SPI needs PV > 0; EAC needs CPI > 0; TCPI needs BAC > AC. Results use floating-point arithmetic and display up to 4 decimal places.
