What an HVAC business in Illinois should charge
Higher wages in Illinois go straight into the price. Take an HVAC business in Illinois paying the state median of $37.21 and run it through the labor rate calculator with its starting numbers (40-hour weeks, 10 paid days off, 2 unbilled hours a day, 7.65% payroll taxes, $90,000 a year of overhead and 15% profit).
| Step | Math | Result |
|---|---|---|
| Paid hours | 40 × 52 | 2,080 |
| Hours at work | 2,080 − 10 days × 8 | 2,000 |
| Billable hours | 2,000 × 6 ÷ 8 | 1,500 |
| Labor cost | $37.21 × 2,080 × 1.0765 | $83,318 |
| Break-even rate | ($83,318 + $90,000) ÷ 1,500 | $115.55 |
| Rate with 15% profit | $115.55 ÷ 0.85 | $135.94 |
That is $135.94 per billable hour, 3.7 times the wage, and $13.84 more than the $122.10 the same math gives at the national median wage.
Paying the 75th percentile instead, $46.17 in Illinois, to hire and keep experienced people raises the rate to $151.67.
A cheaper crew saves less than it seems: at the 25th percentile wage of $28.94, the rate only drops to $121.41.
Overhead, at $60 of every billed hour, and the unbilled hours move this rate more than a raise does. A dollar more in wages adds about $1.76 to the rate.
