OPEX planning · no invented utility tariff or material price
Build a Water Bottling Factory Operating-Cost Model from Your Own Inputs
Operating cost should be calculated from the factory’s own released output, measured or supplier-confirmed consumption, local tariffs, approved material prices, labor plan, cleaning and quality requirements, maintenance history, reject and waste data, warehouse flow and logistics scope. This page does not provide a universal cost per bottle or profit forecast.
01 · Buyer or factory inputs
Information the decision needs
- Electricity, water and compressed-air tariff and measured/confirmed use
- Bottle or preform, cap, label, film, carton, tray and pallet prices
- Labor roles, hours, local rates and shift plan
- Cleaning chemicals, tools and approved frequency
- Maintenance work, consumables and spare-parts history or estimate
- Sampling, laboratory and quality-control cost
- Reject, rework, disposal and product-hold quantities
- Warehouse handling and defined logistics scope
- Released saleable bottles and liters for the same period
02 · Operating objective
What completion should achieve
Create a transparent cost-period model in which quantity, unit rate, source, assumption status and allocation basis are visible and the denominator is released saleable output.
03 · Required controls
Turn the objective into controlled work
- 01
Choose one time period and approved product/format mix
- 02
Record quantity and unit rate separately for every cost line
- 03
Label measured, invoice-based, supplier-reference and estimated inputs
- 04
Use saleable released output rather than nameplate output as the denominator
- 05
Separate fixed, schedule-related and per-unit costs where useful
- 06
Show rejects, holds and waste instead of hiding them in good output
- 07
Update the model when tariffs, materials, shifts, maintenance or product mix change
04 · Factory interfaces
What connects to this decision
- Utility use to operating hours and equipment load
- Packaging consumption to saleable bottles and rejects
- Labor cost to shift coverage and manual handling
- Maintenance cost to availability and spare strategy
- Quality cost and held product to release timing
- Warehouse and logistics cost to final-pack and delivery scope
05 · Evidence to collect
Records that make review possible
- Utility bills, meter readings and tariff records
- Approved supplier invoices or quotations
- Payroll or approved labor-rate basis
- Cleaning and maintenance issue records
- Spare-parts purchase and issue history
- Quality and external-laboratory invoices
- Production, reject, hold and saleable-release reports
- Warehouse and logistics records
06 · Common failure modes
Do not confuse a pattern with a confirmed cause
1Dividing by rated output instead of released output
2Using a price from another country or factory without labeling it
3Ignoring rejects, quality holds or planned cleaning
4Mixing capital expenditure with recurring factory OPEX
5Publishing a precise cost or return period without verified local inputs
07 · Responsibility boundary
Name who confirms each part
| Role | Possible responsibility in this stage |
|---|---|
| Factory finance / owner | Approve cost categories, period, rates and commercial interpretation. |
| Operations / maintenance / quality | Provide measured quantities and operating records. |
| Procurement / warehouse | Provide material prices, issue and logistics evidence. |
| Allot Tech / suppliers | Confirm only the scoped equipment and consumption references available in project documents. |
08 · Completion criteria
Evidence that the stage can advance
- Every material cost has a quantity, unit rate and source
- Utilities and labor match the same operating period
- Rejects, holds and maintenance are visible
- Saleable output is the defined denominator
- Unknowns remain labeled and no unsupported profit or ROI claim is produced
Decision support
Questions operating teams ask
What is the average cost per bottle?
There is no reliable universal value. It depends on local tariffs, package and product, schedule, labor, yield, maintenance, quality and logistics inputs.
Does this page estimate startup investment?
No. It focuses on operating expenses and avoids duplicating the specialist plant-planning and capital-budget scope.
