Apprentice vs. Journeyman Savings Calculator
Every diagnostic hour you can hand to an $18/hr apprentice instead of a $40/hr journeyman is money straight to the bottom line, and senior-tech hours freed for higher-value work. Plug in your numbers to see the yearly total.
Your numbers
Savings = diagnostic hours shifted to the apprentice × (journeyman − apprentice hourly cost), annualized over 52 weeks. The freed journeyman hours are senior-tech capacity you can redeploy to installs, sales, and complex repairs. The catch: those savings only hold if the apprentice can diagnose accurately, which is what a guided decision tree makes possible.
Apprentice vs. journeyman FAQ
How much can an apprentice really save on diagnostics?
The savings is the labor-rate difference on diagnostic time. If a journeyman costs $40/hr and an apprentice $18/hr, every diagnostic hour you shift to the apprentice saves $22. Across a full schedule of service calls that adds up to tens of thousands of dollars a year, the calculator does the math for your shop’s numbers.
Won’t a green tech misdiagnose and cause expensive callbacks?
That’s the real risk, and it’s exactly why the savings only shows up when the apprentice has a system to follow. Guided diagnostic decision trees walk a newer tech to the same root cause a veteran would reach, cheapest, most-common causes first, confirmed with instrument readings.

Should I use the hourly wage or the fully-loaded cost?
Use your fully-burdened cost per hour (wage plus payroll taxes, workers’ comp, benefits, and non-billable time) for the most accurate result. What matters is the difference between the two roles, that gap is what you save on every diagnostic hour you reassign.
Is diagnostic time really the same for an apprentice and a journeyman?
With a guided decision tree the time is comparable, because the tree, not the tech’s memory, drives the sequence. If your apprentices are slower today, raise the average diagnostic time input to reflect reality; the savings still hold because the rate gap is so large.
