Retainage is money you have earned and cannot invoice yet, and it stacks up quietly across a job. The page works out what is payable on this application and what is still sitting behind the retainage line at completion.

Work completed compared

Retainage accumulates as the work does, so each progress application leaves a little more of your own money behind.

What else matters here

A $40,000 contract at 10 percent holds $4,000 and pays $36,000. At 75 percent complete, $3,000 is already held.

Retainage that never appears on paper is retainage that gets forgotten, so bill for it explicitly. Every application should show the amount earned to date, the amount retained to date, and what is payable now. The final application should carry a separate line that names the accumulated retainage and asks for its release.

That is not a formality. The person who releases the money is usually in an office rather than on the site, and they pay what the paperwork asks for. An application that quietly totals to zero because everything has been billed leaves the holdback sitting in a column nobody is looking at, and it will stay there until somebody sends a document asking for it.

What this calculator assumes

  • Retainage is money you have earned that is held back until the job closes out. It is not a discount and it is not a deposit.
  • Most states cap retainage on public work, commonly at 5 or 10 percent, and several require it to be released or reduced at substantial completion. Private contracts are freer and often worse.
  • Retainage is usually the last money a contractor sees and the first thing forgotten at closeout. Track it separately from the invoice balance.

Questions people ask

How much is 10 percent retainage on a $40,000 contract?

$4,000 held and $36,000 payable, with $3,000 already held at 75 percent complete.

How do I invoice for retainage?

Show earned to date, retained to date and payable now on every application, then put the accumulated retainage on the final application as its own line requesting release.

Why does retainage get forgotten?

Because the person paying works from the paperwork. If no document asks for the holdback, nothing prompts anyone in the office to release it.
