How the math works
Three simple formulas, no spreadsheet required.
Monthly savings
Labor + scrap + new profit − operating costs
Labor savings are hours saved per week × your fully burdened rate × 4.33 weeks.
Payback period
Investment ÷ monthly savings
How many months until the machine has paid for itself out of the savings it creates.
First-year return
(Monthly savings × 12) ÷ investment
The share of the purchase you earn back in year one. Every year after that is gain.
The payback is only as honest as the inputs
The calculator will happily tell you whatever your numbers say. The useful answer comes from counting the right things.
Count these in
- The full investment: price, freight, rigging, installation, training, and startup tooling
- A fully burdened labor rate: wages plus benefits, taxes, and insurance
- Scrap and rework you eliminate with tighter, more repeatable cuts
- Outsourced work you can bring back in house
- Overtime you stop paying because the machine keeps up
Leave these out
- Capacity you can't actually sell or staff: new capability only pays when there's work for it
- Savings that depend on perfect uptime: use realistic run hours
- Double counting: if an operator moves to other work, count their hours once
What the spreadsheet doesn’t capture
Some of the best reasons shops buy machines never show up in a payback formula. The operator you can’t hire is the big one: when nobody answers the job posting, automation isn’t about replacing labor, it’s about getting the work out the door at all.
Consistency is another. A machine cuts the thousandth part the same as the first, which means fewer callbacks, fewer remakes, and a reputation for hitting spec.
And downtime works both ways: an aging machine that stops stopping is a saving no line item captures. Quality machinery from established brands also holds resale value, so the investment is never all the way spent.
Run the numbers, then weigh the rest. If the payback is close and the shop is turning work away, the math usually finds a way to say yes.
Machine payback FAQs
How do I calculate the payback period on a machine?
Divide the total investment by the monthly savings the machine creates. Savings are the labor hours it removes times your fully burdened labor rate, plus scrap and rework you avoid, plus profit from new capacity, minus the machine's own operating costs. If a $150,000 machine saves $6,000 a month, payback is 25 months.
What is a good payback period for CNC machinery?
One to three years is typical, and under a year is a strong case. Context matters: a well-built machine runs for ten to twenty years, so even a four-year payback can mean a decade of profit afterward. The riskier the work or the shorter the machine's expected life, the shorter you want the payback.
What should I include in the machine investment?
More than the sticker price: freight, rigging and installation, electrical work, dust collection or air upgrades, operator training, software, and the tooling and workholding you need on day one. Using the delivered, running cost keeps the payback honest.
What counts as savings?
Labor is usually the biggest line: hours of hand work, rework, or extra operators the machine removes, valued at your fully burdened rate. Then add scrap and material yield improvements, outsourced work brought in house, and profit from capacity you can actually sell. Subtract the machine's added power, maintenance, and consumable costs.
Does financing change the math?
Financing spreads the investment over time instead of paying it up front. A useful check: if the monthly savings are larger than the monthly payment, the machine is cash-flow positive from the first month. The payback period itself stays about the same, but the cash never has to leave your pocket all at once.
What about taxes and Section 179?
Section 179 of the US tax code lets many businesses deduct the cost of qualifying equipment in the year it goes into service instead of depreciating it over years, which can shorten the effective payback meaningfully. The limits change yearly, so run your numbers with your accountant. This calculator is a simple pre-tax model.
Should I buy new or used to improve the return?
A quality used machine lowers the investment, which shortens the payback for the same savings. New machinery counters with more capability, full warranty, and the latest controls. Many shops run the numbers both ways and let the payback difference make the call.
