Use a transparent formula
Bottles/day = rated BPH x net production hours/day x effective output factor. Liters/day = bottles/day x bottle liters. Monthly values multiply by working days. Use a percentage as a decimal: 80% means 0.80.
- Rated BPH on the approved bottle and process
- Net hours after planned cleaning and breaks
- Effective output during those net hours
- Bottle volume in liters
- Working days per month
Worked example: 300 BPH over 6.5 net hours
With an assumed 80% effective output, 300 x 6.5 x 0.80 = 1,560 bottles per day. At an approximate 18.9L per bottle this equals 29,484 liters per day. Over 26 working days the estimate is 40,560 bottles per month. This is an arithmetic example, not an output claim for an installed machine.
- An 8-hour shift minus 1.5 hours of planned non-production gives 6.5 net hours
- Use 20L only for an actual approved 20L bottle: the same count would be 31,200 liters/day
- At 70% instead of 80% the same schedule gives 1,365 bottles/day
- Keep the assumptions with the result when sharing it for machine sizing
Avoid counting planned downtime twice
This calculator uses net production hours. If you already subtract scheduled cleaning and breaks from the shift, do not include that same lost time again in the effective-output factor. Use the factor for remaining losses during the net production window, including short stops, speed loss and rejected bottles. Use a clearly labeled range until measured data is available.
- Subtract planned non-production from hours once
- Count short stops inside the remaining window
- Distinguish gross cycles from accepted bottles
- Record bottle or cap supply interruptions
- Do not reuse an unexplained efficiency number from another plant
Convert output into route demand
Production only creates value when clean bottles, delivery routes, warehouse space and return collection can support the same volume. Compare monthly output with expected sales and bottle fleet.
- Current deliveries
- Seasonal peak
- Finished storage
- Bottle fleet
- Return timing
Recalculate after commissioning
Replace planning assumptions with measured gross cycles, saleable output, stop reasons and cleaning duration. This creates a reliable basis for shifts and future upgrades.
- Gross output
- Saleable output
- Stop log
- Reject log
- Shift comparison
