TCPI Calculator
Compute the cost efficiency you must achieve on remaining work to finish within the original budget (BAC) or a revised EAC.
Calculator
TCPI = (BAC − EV) / (BAC − AC)Enter values to compute.
Interpretation Guide
- TCPI ≤ 1.0Remaining work is achievable at current performance.
- 1.0 < TCPI ≤ 1.1Stretch — performance must improve.
- TCPI > 1.1Unrealistic — replan or rebaseline.
Example
BAC $500k, EV $200k, AC $240k → TCPI = 1.15, meaning you need 15% better efficiency than achieved so far.
Real-world use cases
- Sanity check on EAC
- Recovery planning
- Stakeholder transparency
Common mistakes
- Ignoring TCPI when CPI < 1
- Comparing TCPI without scope normalization
Professional tips
- If TCPI keeps climbing, recommend rebaseline
