Definition
Retainage (or retention) is a portion of progress payments withheld by the owner (often 5–10%) until the project is substantially complete or after a warranty period. It protects the owner against defects or incomplete work. The contractor must track retainage held (receivable) and retainage held from subs (payable).
Why It Matters
Retainage ties up cash; large jobs can have significant amounts held. You often pay labor and suppliers at full cost while only collecting 90–95% of approved billings—working capital absorbs the gap until release. Release timing follows owner or GC milestones and contract language, not only your own sense of “done,” so forecasting must track those gates. As a GC, you may withhold from subs for the same protections; money you owe subs can still depend on what the owner has released to you, so sub retainage and your receivable retainage do not always move in lockstep. Tracking what is held, when it is released, and the terms (e.g., half at substantial completion, half after punch list or warranty) is essential for cash flow forecasting and for releasing sub retainage in line with contract and owner payments.
Common retainage structures
Patterns vary by contract; always follow the signed terms.
| Type | When it is withheld | When it is released |
|---|---|---|
| Standard retainage | A fixed % of each progress payment (e.g. 5–10%) | Per contract—often tied to substantial completion, punch list, final acceptance, or warranty periods (sometimes in steps). |
| Step-down retainage | Higher % early (e.g. 10%), then a lower % after a progress threshold (e.g. 50% complete) | Still per contract milestones; mid-project step-down improves cash flow before final closeout. |
| Retainage bond | Usually no cash withheld from progress payments; contractor secures the owner with a bond instead | Release of the bond obligation follows contract closeout terms, not a running cash holdback. |
| Escrowed retainage | Withheld cash is deposited to a separate escrow account (sometimes interest-bearing) | Paid out when contract conditions for release are met, per escrow and contract. |
Retainage vs profit and working capital
Total retainage still outstanding near the end of a job can equal or exceed the profit you expect on that job—so releasing retainage is often what turns “paper” margin into cash. Until then, you are effectively financing part of the project for the owner: same costs to execute, less cash in the door each billing cycle.
Field Example
Contract has 10% retainage. Monthly progress billing is $50,000; owner pays $45,000 and holds $5,000. After 10 months, $50,000 is held. At substantial completion, contract may release half ($25,000); the rest after punch list and warranty. The contractor tracks $50,000 receivable and corresponding amounts held from subs.
Accumulation and final release: $200,000 contract, 10% retainage, five monthly pay applications of $40,000 approved each. Each month the owner remits $36,000 and holds $4,000. After five months, $20,000 retainage is still receivable ($4,000 × 5) even though contract value is fully billed—often in the same ballpark as remaining profit on the job. Final release: when punch list and documentation satisfy the contract, a final application or release draws the $20,000; until then, that balance is cash the contractor has not collected.
Calculation / Formula (if applicable)
Retainage held this period = Billing amount × Retainage %. Total retainage receivable = Sum of retainage held on all progress billings not yet released. Release amounts and timing are per contract.
Software Application
Support retainage % per contract (or per billing). When recording progress billing, calculate and store retainage amount. Track retainage receivable (and payable to subs) by job. Support release events (e.g., substantial completion, final) and partial releases. Report retainage aging and include in cash flow and WIP.
Tooltip Version
Retainage is the portion of progress payments held back until completion; tracking it is critical for cash flow and for releasing sub retainage when you get paid.
