The ROI Math Most Shop Owners Get Wrong | Ep 254
When does buying a CNC machine make more sense than hiring another employee or outsourcing the work? On this episode of Talkin’ Shop with ShopSabre, hosts Brandon Bombardo and Nick Peters answer that question for shop owners weighing automation against labor.
The conversation breaks down how to calculate the real return on investment (ROI) of CNC automation — and why most shop owners get the math wrong. Brandon explains the difference between calculating ROI literally (only the time a task takes) and “paralysis by analysis,” then reframes the core question every owner asks. It isn’t “how many people does this replace?” — it’s “how much inefficiency, does this eliminate?”
Using a cabinet shop example, Brandon contrasts a CNC machine cutting a full base cabinet — dados, shelf holes, hinge pockets and all — in roughly 4 to 8 minutes against an employee doing the same work by hand in 60 minutes or more, with far more room for error. He also walks through a $100,000 job to show that automation doesn’t change the price a customer pays; it changes the profit and the lead time the shop keeps.
They cover the hidden costs of labor that spreadsheets ignore — recruiting, training, turnover, benefits, payroll taxes and absences — and why a $75,000 employee actually costs far more every year, while a machine is a one-time investment that compounds. Brandon and Nick also explain how ShopSabre customers regularly discover entirely new revenue streams after adding equipment they originally bought for a single task.
This episode is for cabinet makers, woodworkers, metal fabricators and manufacturing business owners deciding whether to scale with automation or more labor.
