Label only; no exchange-rate conversion.
Simple operating-month payback
Monthly saving = Loads × (Film saving + Labour minutes saved × Hourly cost/60) − Extra expense; Payback = Investment/Saving
investment = 12000; loads = 2000; fa = 0.9; fb = 0.6; ta = 3; tb = 1; labour = 18; extra = 100 → Simple operating-month payback = 7.058823529 months; Net saving per operating month = 1700 currency/monthSaved calculations stay in this browser. No account or cloud backup is created.
