FREE TOOLS · 4 CALCULATORS
Free tools for operators.
Standalone calculators — no signup, no email. The operator-economics math funded software makes you do by hand, built by the team behind HVAC OS.
HVAC Job Margin & Pricing Calculator
Free HVAC job pricing calculator: enter quote, parts, labor hours, and overhead to see gross profit, gross margin %, break-even price, and effective hourly rate before you send the estimate.
HVAC Billed Hourly Rate Builder
Build your HVAC billed hourly (door) rate from shop overhead, fully-loaded labor cost, billable efficiency, and target net margin. See the rate that actually funds profit — plus your break-even rate and total billable hours — so flat-rate pricing stops guessing.
HVAC Maintenance Plan Pricing & ROI Calculator
Price your HVAC maintenance agreements and see real ROI: annual recurring dues revenue, gross profit after the cost of delivering tune-ups, and the repair pull-through profit members generate. Set membership pricing that actually pays instead of breaking even on visits.
HVAC Technician Break-Even & Billable-Hours Calculator
Find each HVAC tech's break-even: how many billable hours a day they must invoice to cover their fully-loaded cost plus overhead, the billable percentage required, and the annual profit they contribute at your door rate. Decide whether to hire, reprice, or fix scheduling.
The numbers behind the decisions.
Most software built for owner-operators of 5–30-truck HVAC contractors handles the workflow but leaves the economics to a spreadsheet — pricing, margin, break-even, commission, capacity, and ROI. These are the calculations that decide whether a job, a hire, a plan, or a price is actually worth it, and they usually live in a founder's head or a tab that never gets opened.
Every calculator here is free, instant, and runs entirely in your browser — no account, no email, nothing stored. Adjust the inputs and the outputs update live. Each one is a planning estimate meant to inform a decision, not replace your accountant. They're the same operator-side math HVAC OS keeps running automatically once the guesswork is behind you.
