The payback period mainly depends on your local raw material cost, finished mesh selling price, daily production volume and labor expense. ROI & Payback Period Calculation Formulas 1.Daily Net Profit = (Unit selling price of finished mesh − Raw material cost per ton − Daily labor & power cost) × Daily output tonnage 2.Monthly Net Profit = Daily Net Profit × 30 working days 3.Total Equipment Investment = Machine cost + Shipping & customs cost + Installation auxiliary expense 4.Payback Cycle (Months) = Total Equipment Investment ÷ Monthly Net Profit For most clients producing roll wire mesh or construction rebar mesh, the average payback cycle ranges from 5–12 months. If your local building material demand is high and raw material price is stable, you can recover all investment within 5–9 months.
