Prevailing Wage Calculator
The arithmetic contractors actually get wrong on public work — not the rate. You supply that off the schedule.This tool takes the base rate and supplement figure you read off your wage schedule and does the math: total hourly package, straight time / overtime / double time, a crew and job cost roll-up, and a certified-payroll sanity check. Type in the numbers your bid documents and wage determination already gave you.
It will never supply, look up, guess, or default to a wage rate. Rates change by trade, county, funding source, and schedule — a wrong one here could cost you a bid or put you out of compliance. Get your rate from the sources below, not from us.
The wage schedule, classification, supplements, and your bid documents control — not this calculator. This tool only does arithmetic on figures you type in. It is not legal or labor-law advice, and it is not a substitute for the wage determination named in your contract. Confirm your trade classification, applicable schedule, and OT/holiday rules with the contracting agency, the NYC Comptroller, NYS DOL, or your own counsel before you price or run payroll.
Public work in NYC generally runs under one of two systems — sometimes both: NY Labor Law 220 (NYC Comptroller schedules for city contracts, NYS DOL for state and other public work) or Davis-Bacon for federally funded work (wage determinations on SAM.gov, WH-347 certified payroll). Where both apply, the higher rate governs. Read the actual determination named in your bid documents — never price off a generic table.
Runs entirely in your browser. Nothing you type is sent anywhere or stored on our servers — the only thing saved is an optional local copy of your crew list, kept on this device so you don't have to retype it, which you can clear at any time below.
Where the rate actually comes from
Pull the base rate and supplement figure for your trade, county, and schedule date from one of these — then bring the numbers back here.
Job Settings
These apply to the whole crew below. The schedule governs which hours are premium — 8-hour day vs. 40-hour week, and Saturday/Sunday/holiday rules differ by trade and by contract. Set the multipliers to match what your wage determination actually says.
Crew Builder
One row per trade/classification. Base and supplement are the numbers off your schedule for that classification — not a guess. Leave apprentice % blank for journeyman (100%).
Results

Labor burden is your own workers'-comp, general-liability, and payroll-tax loading — not part of the prevailing wage package. It is broken out on its own line so it never gets confused with wages or supplements on a certified payroll.
Certified-Payroll Sanity Line
Total hours and gross figures for this pay period, formatted to check against what you're about to certify — not a substitute for the certified-payroll form itself.
Hours and gross figures are for one pay period across the whole crew above (not multiplied by weeks). NYC contracts bid on or after December 31, 2025 must have certified payrolls submitted electronically through NYC eComply — check your contract's bid date before you file on paper. Every submission is still checked against the classification and rate in your wage determination, not against this tool.
Not legal or labor-law advice. This tool performs arithmetic only, on figures you supply — it does not verify classifications, schedules, or compliance. When in doubt, confirm with the contracting agency or your own counsel.
