What is Subcontract Retention Percentage?
A contract cash-flow KPI for GCs and owners. Distinct from punch-list completion—this is dollars retained, not defects closed.
- Same subcontract for both amounts
- Billed = approved pay-app base per policy
- Watch release schedules
The Formula
Worked Example
Common Use Cases
- Pay apps: retainage checks
- Subcontractor cash flow: held funds
- Closeout: retention release readiness
Pro Tips
- Align with contract retainage %
- Separate stored materials rules
- Track cumulative vs period
| 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: Subcontract Retention Percentage 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.

- 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.
