How much retainage is typical in construction?

Five to ten percent is the common range, with ten percent the traditional default and five percent increasingly common, especially once a job is well along. Many contracts also allow retainage reduction: the rate drops, often from ten to five percent, once the project passes a milestone such as fifty percent complete and the owner is satisfied with performance. Some public projects cap retainage by statute, and the exact rate is always a contract term, so it is set before the first pay application rather than decided period to period. On our example we use a flat ten percent for clarity.

When is retainage released?

In stages, tied to completion rather than to a date. A portion is often released at substantial completion, when the owner can occupy and use the work, with the remainder held until final completion, when the punch list is finished, closeout documents are delivered, and lien waivers are in hand. Releasing retainage is a deliberate step: the owner is giving up the leverage that motivated the contractor to return for the last details, so it is withheld until there is little reason left to chase anyone. The final release is frequently the last significant payment on a job.

What is the difference between retainage and a retention bond?

Both protect the owner, but one ties up the contractor's cash and the other does not. Retainage physically withholds money from each payment, so the contractor finances the held amount until release. A retention bond is a surety instrument the contractor provides in place of cash retainage: the owner gets the same security, a guaranteed source of funds if the work is not completed, but the contractor keeps its cash flowing instead of leaving it in the owner's account. Retention bonds are common where the retained sums are large enough that the cash-flow cost to the contractor is significant.

Retainagein Construction

A slice of every payment the owner keeps until the job is done. It is the leverage that gets the punch list finished, and a real cash-flow cost to the contractor until it is released.

Definition

Retainage (also called retention) is the portion of each construction progress payment, usually five to ten percent, that the owner withholds until the work is substantially or fully complete. It accrues in a running balance across every pay application and is released near the end of the job, protecting the owner and motivating the contractor to finish cleanly.

It accrues, then it releases

On our $12.0M project at 10%, each pay application adds to the retained balance. By Application 8, with $5.7M completed and stored, $0.57M is being held, all of it released once the job is finished and closed out.

Who it protects, and what it costs

Protects the owner

The held balance is a reserve against defects, incomplete work, and liens. As long as the owner holds a meaningful slice, the contractor has reason to come back and finish right.

Costs the contractor

Retained dollars are earned but unpaid, so the contractor finances them until release. On a long job the cash-flow cost is real, which is why contractors negotiate the rate and press for reduction.

Flows down to subs

A general contractor usually withholds the same retainage from its subcontractors. So the owner holds from the GC, and the GC holds from the trades, all the way down the chain.

How POD tracks retainage

When POD reads a pay application, it separates the retainage from the amount due and reconciles the running retained balance across applications, so the held total and the net check each period are explicit rather than buried in the form. That means the retained balance and the amount still due are tracked figures, ready for the closeout conversation instead of recomputed by hand at the end.
