title="Equipment ROI Calculator">
</iframe>Equipment ROI is calculated by comparing the total net income the equipment generates over its useful life against its purchase cost. The key variables are: net revenue per session (gross revenue minus consumables), sessions per day, working days per week, annual maintenance costs, and expected lifespan. A quality rotary machine costing £400, used for 3 sessions/day at £150 net per session, generates payback in under 2 sessions at full capacity. The more meaningful metric for most artists is the payback period in days or weeks — that's the real cash-flow risk horizon.
Professional-grade rotary machines from established manufacturers (FK Irons, Cheyenne, Bishop) are designed for 5–7 year operational lifespans with proper maintenance. Coil machines, being simpler mechanically, can last 10+ years with regular service. Power supplies typically last 3–5 years before internal capacitors and regulators begin to drift. Autoclaves have regulatory service intervals and pressure vessel certification requirements that typically govern their operational life at 7–10 years. Needle cartridges and disposables are single-use. A logbook that tracks machine hours and service events is essential for accurate lifespan estimation and resale valuation.
