Retainage in construction: the money you earned but haven't been paid.
Retainage is the quiet drag on every contractor's cash flow: a slice of each payment the customer holds back until the very end. Understood and tracked, it's just part of the deal. Ignored, it's thousands of dollars of earned money you forget to chase. Here's how retention actually works, and how to get it released.
Retainage (also called retention) is a percentage, usually 5–10%, that the customer withholds from each construction payment until the project is finished and accepted. The held amount, the retention balance, is released at close-out once the work is complete and the punch list is cleared. Retainage and retention mean the same thing. To get paid, track the running balance from day one and invoice it cleanly at the end.

What retainage is, and why owners hold it
Retainage is a portion of each progress payment that the owner or general contractor keeps back rather than paying out, holding it until the job is substantially or fully complete. The purpose is leverage and security: it gives the party paying you a financial reason to be confident you'll finish the work, clear the punch list, and stand behind it. It's standard practice, especially on commercial and public work, and increasingly common on larger residential jobs.
Mechanically, if you bill $10,000 with 10% retainage, you get paid $9,000 now and the remaining $1,000 goes into a retention balance that accumulates across the project. Finish the job and clear the requirements, and that accumulated balance is released.
Retainage vs. retention
These are two words for the same thing. "Retention" shows up more on certain contract forms and in some regions; "retainage" is common in the United States. Don't let the two terms confuse you, both mean the percentage of payment withheld until completion. If a contract uses one word in one clause and the other word elsewhere, they still refer to the same held-back money.
How much, and when it drops
Typical retainage is 5% to 10% of each payment. Two things worth knowing and negotiating:
- Step-downs. Many contracts let the rate fall at a milestone, say from 10% to 5% once the job is 50% complete. If yours doesn't, ask for it. The cash you free up is money you already earned.
- Caps. Several states limit the maximum retainage allowed, particularly on public projects and sometimes private ones. If a contract holds more than your state permits, that's worth flagging before you sign.
How retainage hits your cash flow
Retainage is profit you've earned but can't spend yet, and on a thin-margin job, the retention balance can be most of your profit sitting in someone else's bank account for months. That's why contractors who are profitable on paper still run short on cash: a meaningful chunk of every dollar billed is parked in retention until close-out.
On a progress invoice, retainage should be shown as its own deduction line so the running balance is always visible, both for your cash planning and so the final release isn't a surprise. The construction invoice template shows exactly where retention sits on the bill.
How to track and recover it
Getting retainage paid is mostly about not letting it slip through the cracks:
- Track the running balance from day one. Every invoice should show gross billed, retention deducted, and the cumulative retention held. If you don't know the number, you can't collect it.
- Clear the punch list fast. Retainage releases at substantial or final completion. Every open punch item is a reason to keep holding your money.
- Send a clean final retention invoice. A separate close-out invoice for the accumulated retention, referencing the contract and prior payments, so there's no ambiguity about what's owed.
- Submit closeout documents promptly. Lien waivers, warranties, as-builts, whatever the contract requires. Missing paperwork is the most common reason a release stalls.
- Know your prompt-payment clock. Many states set a deadline for releasing retention after completion, with interest if it's late. That deadline is your leverage.
State limits and prompt-payment rules
Retainage is heavily governed by state law, and the rules differ for public versus private work. Many states cap the percentage that can be withheld, require retained funds to be released within a set window after completion, and in some cases require retention to be held in escrow or to accrue interest. On public projects the rules are usually stricter and more contractor-friendly. Before you sign a contract with retention terms, it's worth knowing what your state actually allows, sometimes a clause asks for more than the law permits.
Retainage FAQ
There's no real difference, they're two words for the same thing. Retention is more common on some contract forms and in some regions, retainage in others, especially in the United States. Both mean the percentage of payment held back until project completion.
Retainage is commonly 5–10% of each progress payment. Many contracts allow the rate to drop, for example from 10% to 5%, once the project reaches a milestone such as 50% complete. Several states cap the maximum retainage allowed on public and sometimes private projects.
Retainage is released at substantial or final completion, after the punch list is cleared and any required closeout documents, lien waivers, warranties, as-builts, are submitted. To get paid promptly: track the running retention balance from day one, send a clean final retention invoice that shows it, clear the punch list fast, and know your state's prompt-payment rules for retention.
