Built for capital decisions: the discount rate and NPV matter here more than in any marketing model, because equipment money is locked in for years.
Enter your numbers first, then use the niche guidance below to interpret the output against shop owners, contractors, manufacturers, and clinic or studio operators evaluating five-figure-and-up equipment purchases..
Equipment decisions are where ROI math earns its keep. The purchase is large and irreversible, the benefits arrive over years, and the alternative, keeping cash or financing something else, has a real cost. A machine that returns 20 percent over two years may still lose to that comparison once you discount the cash flows.
Enter the full installed cost, including delivery, installation, and initial tooling, as the initial investment. Monthly revenue is the new capacity you can actually sell, or the costs the machine removes. Monthly costs cover power, consumables, maintenance, and the operator time the machine demands.
Monthly net profit is added revenue or savings minus operating costs. ROI compares cumulative profit over the period to the installed cost. Payback period divides installed cost by monthly profit. NPV discounts each month's profit at your chosen rate, which is where financed purchases and long horizons get honest.
A fabrication shop considers a $45,000 CNC machine, installed. Work currently outsourced would return as roughly $6,500 in monthly billable capacity. Running the machine costs $2,100 a month in power, tooling, maintenance, and operator time. They model 24 months with a 10 percent discount rate.
Net profit of $4,400 a month pays the machine back near month ten, with a positive NPV over two years. The assumption to stress is utilization: the $6,500 only materializes if the work actually fills the machine. At half utilization the payback stretches past twenty months and the case weakens sharply.

No. This is a cash-flow model. Depreciation affects taxes and book value; discuss those effects with your accountant alongside this output.
Either model the full price upfront and compare NPV at your loan rate, or put the down payment as initial investment and loan payments into monthly costs. Pick one; do not mix them.
At minimum your real borrowing cost. Many small businesses use 8 to 12 percent to reflect risk and the value of keeping cash flexible.
