Retainage
Retainage is a percentage of each progress payment that an owner or lender withholds from a contractor until the work is complete, held back to ensure the contractor finishes the job and corrects defects. It is released at substantial or final completion, and it flows down through subcontractors on the same terms.
How Retainage Works
Retainage works by holding back a fixed percentage from every progress payment across the life of a construction contract, then releasing the accumulated sum once the work is accepted. The withheld amount, typically 5 to 10 percent per draw, sits with the owner or lender as security until substantial completion, giving the paying party recourse if the contractor walks or leaves punch-list work undone.
Retainage is deducted on the construction draw request. When a contractor bills for work in place, the owner pays the invoiced amount less the retainage percentage, and the held-back funds accumulate in a running balance. Per the AGC and ABA Construction State Law Matrix, which tracks retainage release across all 50 states, statutes commonly cap the rate and set a deadline for release after substantial completion or final acceptance.
Many contracts reduce the rate partway through the job. A common structure withholds 10 percent on early draws, then drops to 5 percent or zero once the project reaches 50 percent completion. Retainage also flows down: a general contractor that has 5 percent withheld typically withholds the same rate from its subcontractors, so the burden compounds down the payment chain.
Mechanism | Treatment |
|---|---|
Rate per draw | Typically 5 to 10 percent of each progress payment |
Reduction milestone | Often lowered at 50 percent completion |
Release trigger | Substantial or final completion, subject to punch list |
Flow-down | General contractor withholds the same rate from subs |
Why Retainage Matters
Retainage matters because it shifts working capital away from the parties doing the work and toward the party holding the funds. A subcontractor operating on a 3 to 5 percent net margin can see its entire profit tied up as retainage on an active job, since 5 to 10 percent withheld from every draw often exceeds the margin embedded in the contract. The cash is earned but not collected until completion.
For the owner and lender, retainage is leverage. The withheld balance is the last money a contractor sees, so it creates a strong incentive to complete punch-list items, deliver closeout documents, and resolve defects before final payment. That is why lenders build retainage into construction loans and require it on subcontracts they fund.
The quotable point for an operator: retainage is the only leverage an owner keeps after the building is standing, so releasing it early trades the strongest completion incentive for goodwill.
Example
A subcontractor holds a $1,000,000 contract billed across four equal draws of $250,000. The owner withholds 10 percent on the first two draws, then reduces to 5 percent for the balance once the job passes 50 percent completion. The retainage accumulates until it is released at final completion.
Draw | Billed | Retainage rate | Withheld | Paid this draw |
|---|---|---|---|---|
1 | $250,000 | 10% | $25,000 | $225,000 |
2 | $250,000 | 10% | $25,000 | $225,000 |
3 | $250,000 | 5% | $12,500 | $237,500 |
4 | $250,000 | 5% | $12,500 | $237,500 |
Total | $1,000,000 | $75,000 | $925,000 |
Across the job the owner withholds $75,000, released at final completion. If the subcontractor's margin on the $1,000,000 contract is 5 percent, or $50,000, the retainage balance of $75,000 exceeds the entire profit, so the sub is financing the owner until release.
Variations and Edge Cases
Retainage terms vary by state, project type, and contract, and the differences change how much cash is withheld and how fast it comes back. Public projects are usually capped by statute, while private projects range from a hard statutory cap to fully open negotiation. The table below covers the variants an operator should confirm before signing.
Variant | Treatment |
|---|---|
State statutory cap | Many states cap public-project retainage at 5 percent; federal projects cap at 10 percent under FAR 52.232-5 |
Private-project caps | Some states impose no cap; New York caps private contracts of $150,000 or more at 5 percent |
Retainage bond | A surety bond substituted for cash retainage, freeing the withheld funds while preserving security |
Line-item release | Retainage released trade by trade as each scope completes, rather than all at the end |
Reduced retainage | Rate stepped down or dropped at a completion milestone, often 50 percent |
Per Holland & Knight, New York's 2023 amendment to the Prompt Payment Act limits retainage on private construction contracts of $150,000 or more to 5 percent and requires release within 30 days of final approval, with interest of 1 percent per month on late retainage. A 2025 amendment renders void any private-contract provision that exceeds the 5 percent cap.
Retainage vs Holdback
Retainage is often confused with holdback, and the two overlap, but they are not identical. Retainage is a defined percentage withheld from each progress payment across a construction contract, released at completion. Holdback is a broader term for any sum a paying party retains against a future obligation, used in construction, in mergers, and in escrow arrangements far beyond a build.
In practice, retainage is a specific form of holdback tied to construction progress payments and governed by state prompt-payment statutes. A holdback in a purchase and sale agreement, by contrast, might cover indemnity claims or unresolved repairs and is governed by the contract alone. All retainage is a holdback; not all holdbacks are retainage.
Frequently Asked Questions
What is retainage in construction? Retainage in construction is a percentage of each progress payment, typically 5 to 10 percent, that an owner or lender withholds from a contractor until the work is complete. It ensures the contractor finishes the job and corrects defects, and it is released at substantial or final completion.
How much retainage is typically withheld? Retainage is typically withheld at 5 to 10 percent of each progress payment. Many states cap public-project retainage at 5 percent, and federal projects cap at 10 percent under FAR 52.232-5. Contracts often reduce the rate at 50 percent completion.
When is retainage released? Retainage is released at substantial or final completion, once the contractor finishes punch-list work and delivers closeout documents. Many state statutes set a deadline, commonly 30 days after final approval or acceptance, and impose interest on retainage held past that date.
What is a retainage bond? A retainage bond is a surety bond a contractor posts in place of cash retainage. It gives the owner the same security against non-completion while releasing the withheld cash back to the contractor, easing the working-capital strain that retainage creates.
