Understanding Percent Complete
How we calculate. % complete = earned/physical progress ÷ planned quantity × 100. See our methodology and accuracy policy .
Real-world scenario: A typical Percent Complete case uses progress achieved 7500 and planned quantity 10000. Enter the same figures below to reproduce the worked path.
What is Percent Complete?
A field progress KPI. Distinct from earned-value SPI on the Professional hub—this page is simple quantity or physical % complete.
- Same UOM for progress and planned
- Freeze the planned quantity
- Cross-link SPI/CPI for EV analytics
The Formula
Worked Example
Common Use Cases
- Daily reports: activity progress
- Owner updates: physical % done
- Pay apps: quantity-based complete
Pro Tips
- Don’t mix cost % and physical %
- Watch scope changes
- See Professional SPI for EV
| Scenario | When to use |
|---|---|
| Percent of a number | Finding a part of a whole (tax, tip, score) |
| Percent change | Comparing old vs new values |
Limitations: Percent Complete results are educational construction planning aids—not engineering, safety, legal, or cost-estimating advice. Confirm definitions with your project controls, safety, and contract documents. For earned-value SPI/CPI see the Professional hub.
Common mistakes
- Swapping part and whole: The denominator must be the full total, not a subset.
- Rounding too early: Carry extra decimal places through multi-step work before rounding the final percent.
- Mixing percent and decimal forms: Enter rates in the format the calculator labels expect.
