You finish the work, submit your pay application, and the check arrives 10% short. That missing amount is retainage in construction: money the owner holds back until the project is complete. It protects the owner, but it also ties up a large share of a contractor’s profit for months. Understanding how retainage works, and pricing it into your bid, is part of running a healthy construction business.
Retainage is a portion of the contract price that is earned but not yet paid. The owner keeps it as security that the contractor will finish the job, correct defects and deliver closeout items. General contractors usually pass the same terms down to their subcontractors, so retainage affects everyone on the project.
Retainage is different from a payment bond or a performance bond. A bond is a guarantee from a surety company. Retainage is actual cash held from the contractor’s own earnings.
On most projects the contractor bills monthly using a schedule of values. Each pay application shows the work completed to date, the retainage withheld, and the amount due. Standard forms such as the AIA G702/G703 have separate lines for retainage on completed work and on stored materials.
| Pay Application Line | What It Shows |
|---|---|
| Total completed and stored to date | Value of all work done so far |
| Retainage | Percentage withheld from that value |
| Total earned less retainage | What the contractor has earned in cash |
| Less previous payments | Amounts already paid |
| Current payment due | The check for this period |
| Project Type | Common Retainage | Notes |
|---|---|---|
| Private commercial | 5% – 10% | Set by contract; often reduced at 50% completion |
| Public (state and local) | Often capped at 5% to 10% | Many states set limits and release deadlines |
| Federal | Case by case | Withheld mainly when progress is unsatisfactory |
| Residential | Often none or small | Depends on the contract |
Retainage laws change by state and by project type, so read your contract and your state’s prompt payment rules before you bid.
A subcontractor has a $500,000 contract with 10% retainage. The contract reduces retainage to 5% overall once the work is 50% complete.
| Pay App | Work This Period | Retainage Held | Cash Paid |
|---|---|---|---|
| 1 | $100,000 | $10,000 | $90,000 |
| 2 | $150,000 | $15,000 | $135,000 |
| 3 (reduction to 5%) | $150,000 | $0 (total held drops to $20,000) | $155,000 |
| 4 | $100,000 | $5,000 | $95,000 |
| Final release | — | Releases $25,000 | $25,000 |
In pay app 3, retainage on $400,000 of work at 5% is $20,000, so $5,000 of the earlier $25,000 is released with that payment. By the end, $25,000 waits until closeout, which is often months after the last day on site.
Most contracts release retainage in one or two steps:
Typical closeout items include final lien waivers, warranties, O&M manuals, as-built drawings, attic stock and a consent of surety. A slow punch list is one of the most common reasons retainage is delayed.
Retainage does not reduce the contract price, but it does cost you money while it is held. Smart estimators include that cost.
If $50,000 is held for 6 months and your line of credit costs 8% a year, the carrying cost is about $50,000 × 8% × 0.5 = $2,000. That belongs in overhead or general conditions.
Some contractors overvalue early line items in the schedule of values to offset retainage. Owners and lenders watch for this, and it can damage trust. Price the real cost instead.
Withhold the same retainage from your subcontractors that the owner withholds from you, and release it on the same schedule, so you are not financing the whole job yourself.

Usually 5% to 10% of each progress payment. Many contracts reduce it to 5% once the work is 50% complete.
Yes. Retainage and retention mean the same thing: money withheld from progress payments until the work is complete.
Usually at substantial or final completion, after the punch list is finished and closeout documents such as lien waivers and warranties are delivered.
Yes. General contractors usually withhold the same percentage from subcontractors that the owner withholds from them, subject to state law.
The retained amount is part of the contract price, but the cost of financing it while it is held should be included in overhead or general conditions.
