Folios can be configured to use Earned Value Management (EVM) to provide a health status of the project through calculated performance indices. EVM indices are calculated from the folio's available financial data (planned and actual costs or revenues) as well as JIRA issues progress and work logs. The following table lists the EVM indices calculated by Tempo Budgets and the basic values that are used in those calculations.

EVM basic values and indices

Basic values	Definition	Description
PV	Planned Value	Planned Value at a given point in time. Note that Planned Value (PV) must not be confused with Planned Cost to date (or Planned Revenue to date) that is shown in the Financials sections of the folio's overview. Planned Value is a value obtained by distributing the Total planned costs linearly over the Folio time frame. For that reason, PV indicates the progress in the project's schedule (i.e. how many working days elapsed over the total number of working days in the folio's timeframe).
AC	Actual Cost	Known cost of work performed at a given point in time.
EV	Earned Value	Measure of work performed at a given point in time.
BAC	Budget At Completion	Total Budget estimated.
TPV	Total Planned Value	Same as Budget at completion (BAC).
Indices (Performance)
CPI	Cost Performance Index	Determines how efficiently the staff members are using the resources. EV / AC Favorable if over 1.0. Unfavorable if under 1.0.
SPI	Schedule Performance Index	Determines how efficiently the project staff members are using their time. EV / PV Favorable if over 1.0. Unfavorable if under 1.0.
TCPI	To-Complete Performance Index	Determines the efficiency that must be achieved on the remaining work for a project to meet the Budget at Completion (BAC - EV) / (BAC - AC)
Indices (Variance)
CV	Cost Variance	Determines if the project is over or under budget. EV - AV Under budget if over 0. Over budget if under 0.
SV	Schedule Variance	Determines if the project is ahead or behind budget EV - PV Ahead of schedule if over 0. Behind schedule if under 0. SV% = SV / PB Convert SV to Percentage
VAC	Variance At Completion	Determines whether the project will finish under or over budget. BAC - EAC Under budget if over 0. Over budget if under 0. VAC% = VAC / PB Convert VAC to Percentage
Indices (Forecast)
ETC	Estimate To Complete	Estimated cost of the project at the end of the project ETC = (BAC - EV) / CPI
EAC	Estimate At Completion	Estimated cost to complete the project EAC = BAC / CPI
EAC_t	Time Estimate At Completion	Rough estimate in working days of when the project will be completed. (BAC / SPI) / (BAC / total planned time)
