What is an hourly rate in construction?

An hourly rate is either the wage a worker earns per hour or the price a contractor charges a client per labor hour. The two numbers are very different, and mixing them up loses money.

In construction, "hourly rate" has two meanings. The pay rate is what the worker earns for each hour. The billing rate is what the contractor charges the customer for that hour on time and materials work or service calls. The billing rate has to cover the pay rate, the employer's labor burden, a share of overhead, and profit.

A carpenter who earns $32 an hour does not cost the company $32 an hour. Payroll taxes, workers' comp, benefits, paid time off, and unbilled time all ride on top. Bill that carpenter at $45 and you may be losing money on every hour.

From pay rate to billing rate: a worked example

Say a remodeler pays a lead carpenter $32.00 an hour. The steps below use clearly made-up percentages to show the method; plug in your own numbers.

Example: building a billable hourly rate
StepPer hour
Base pay rate$32.00
Labor burden (taxes, comp, benefits) at an assumed 35%$11.20
Fully burdened cost$43.20
Overhead recovery at an assumed $18.00 per billable hour$18.00
Break-even cost per hour$61.20
Profit at an assumed 15% margin on price$10.80
Billing rate$72.00

The profit step uses margin, not markup: $61.20 divided by 0.85 is $72.00. Mixing the two is a common error covered under markup.

Overtime and the regular rate

Under the federal Fair Labor Standards Act, covered non-exempt employees must be paid at least one and one-half times their regular rate for hours over 40 in a workweek. A workweek is a fixed, recurring 168-hour period, and hours cannot be averaged across two or more weeks. The regular rate generally includes all pay for work, with some exclusions such as expense reimbursements and discretionary bonuses. Some states add daily overtime or other rules, so check your state labor agency.

Overtime changes the billing math. If a crew works 50 hours to hit a deadline, the last 10 hours cost 1.5 times the base pay plus the burden that rides on it. Unless the contract lets you bill premium time, that cost comes out of margin.

Hourly rate on prevailing wage jobs

On public work, the wage determination sets the minimum basic hourly rate and fringe rate by classification. You can pay more, never less. Your billing rate for change orders on those jobs must start from the prevailing rate, not your normal shop rate. See prevailing wage.

Common mistakes

  1. Billing at the pay rate plus a small markup, ignoring burden and overhead.
  2. Using one blended rate for every worker, which overprices apprentices and underprices foremen. A labor rate table by classification fixes this.
  3. Forgetting that not every paid hour is billable. Drive time, shop time, and training dilute the rate.
  4. Averaging hours across weeks to avoid overtime, which federal law does not allow.

Frequently asked questions

What is the difference between a pay rate and a billing rate?

The pay rate is what the worker earns. The billing rate is what the customer pays and must cover wages, burden, overhead, and profit.

When is overtime required for construction workers?

Federal law requires at least time and one-half the regular rate for covered non-exempt employees after 40 hours in a workweek. Some states have stricter rules.

Can I average hours over two weeks to avoid overtime?

Not under the federal Fair Labor Standards Act. Each workweek stands alone.

How often should I update my hourly billing rates?

At least once a year, and any time wages, insurance, or overhead change significantly.
