Tool

Davis-Bacon Certified Payroll Calculator

A federal job runs on a wage determination, not your usual rates. Enter the base prevailing wage and fringe benefit rate for a classification, along with hours worked, to see the required cost per worker and the crew total, with overtime split out correctly.

This is a calculation aid only, not a source of official wage rates. Confirm your project’s actual wage determination on SAM.gov or with your awarding agency before you rely on any number here. Davis-Bacon compliance also involves certified payroll reporting, apprentice ratio rules, and fringe benefit substitution rules that this tool does not cover.

1. Classification & Rates

Enter the rates from your project’s actual wage determination.

Worker classification / trade

Base prevailing wage rate

This tool doesn’t look up rates. Prevailing wage rates vary by state, county, and classification, and change periodically. Find your project’s actual rate on SAM.gov.

Fringe benefit rate

2. Hours & Crew

Regular and overtime hours, and how many workers are in this classification.

Regular hours

Overtime hours

Overtime is paid at 1.5x the base rate only. The fringe benefit rate stays at the straight-time amount for every hour, including overtime, under 29 CFR § 5.32.
