Subcontract Retention Percentage

A contract cash-flow KPI for GCs and owners. Distinct from punch-list completion—this is dollars retained, not defects closed.

Retention % = retainage held ÷ subcontract billed × 100.

Tip: Keep “Retention Held” and “Subcontract Billed” on the same basis (period, units, and population) before calculating Subcontract Retention Percentage.

Subcontract retention percentage compares retainage held to subcontract amounts billed.

Enter retention held and subcontract billed for the same subcontract and period.

Understanding Subcontract Retention Percentage

How we calculate. Retention % = retainage held ÷ subcontract billed × 100. The form uses the same arithmetic as the worked examples on this page. See our methodology and accuracy policy.

Real-world scenario: A typical Subcontract Retention Percentage case uses retention held 50000 and subcontract billed 500000. Enter the same figures below to reproduce the worked path.

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

Subcontract Retention Percentage
Retention % = (Retention held ÷ Subcontract billed) × 100

Worked Example

Scenario: Retention held $50,000; subcontract billed $500,000.
Step 1: 50000 ÷ 500000 = 0.1
Step 2: × 100 = 10%
Answer: Subcontract retention is 10%.

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

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.

FAQ

Held or contract retainage rate?

This form is held ÷ billed. The contractual retainage rate is often a fixed %—compare actual held to that rule.

What if subcontract billed is 0?

Retention % is undefined—enter a positive billed amount.
