Davis-Bacon Prevailing Wage Calculator
The Davis-Bacon Act sets a prevailing wage for laborers and mechanics on covered federal construction contracts, expressed as a basic hourly rate plus a fringe benefit amount from the applicable wage determination. Overtime on covered contracts is generally paid at 1.5 times the basic hourly rate for hours over 40 in a workweek, while the fringe rate is paid on all hours without the overtime multiplier. This calculator takes the basic rate, the fringe rate, and the hours worked in the week, then computes straight-time pay, overtime pay, fringe pay, and the total weekly prevailing wage compensation.
Prevailing wage formula
Straight hours = min(hours, threshold)
Overtime hours = max(0, hours - threshold)
Straight pay = straight hours * basic rate
Overtime pay = overtime hours * basic rate * 1.5
Fringe pay = total hours * fringe rate
Total = straight pay + overtime pay + fringe pay
Overtime applies the 1.5 multiplier to the basic rate only. The fringe rate is paid straight on all hours, including overtime hours, unless the contract specifies otherwise.
US Davis-Bacon context
- Davis-Bacon applies to covered federal and federally assisted construction contracts above a threshold.
- The prevailing wage is the basic hourly rate plus the fringe benefit rate from the wage determination.
- Fringe benefits can be paid as bona fide benefits or as cash; both satisfy the fringe obligation.
- Overtime on covered contracts is 1.5 times the basic rate for hours over 40 per week.
- Wage determinations are published by the U.S. Department of Labor by classification and locality.
Prevailing wage: frequently asked questions
What is the Davis-Bacon prevailing wage?
On covered federal and federally assisted construction contracts, the Davis-Bacon Act requires laborers and mechanics to be paid at least the locally prevailing wage, which is a basic hourly rate plus a fringe benefit amount, as set in the applicable wage determination for the work classification and location.
How are fringe benefits handled?
The fringe benefit portion can be paid as bona fide benefits, as cash added to the basic rate, or a combination. Total prevailing compensation equals the basic hourly rate plus the fringe rate. This calculator adds both and lets you see the combined hourly package.
How is overtime calculated under Davis-Bacon?
Overtime is generally computed at 1.5 times the basic hourly rate (not the fringe rate) for hours over 40 in a workweek under the Contract Work Hours and Safety Standards Act. The fringe rate is typically paid on all hours worked, including overtime hours, without the 1.5 multiplier.
Where do I find the wage determination?
Wage determinations are published by the U.S. Department of Labor and available through the System for Award Management. Enter the basic rate and fringe rate from the determination for your classification and county as user-editable inputs.
Does Davis-Bacon set a daily overtime rule?
The federal overtime trigger for covered contracts is generally 40 hours per workweek. Some contracts or state little-Davis-Bacon laws may impose different rules. Confirm the rules in your contract and wage determination.
