How to Read a Dyehouse Batch Card for Accurate Costing
A dyehouse batch card holds the raw data for costing, but most plants stop at the recipe and never convert it into a defensible batch cost.
What this covers
- Break down every line on the batch card into material, labour, utility and overhead components.
- Use actual consumption, not standard rates, to avoid cost drift over time.
- Allocate shared utilities such as steam and effluent by measurable drivers like kilos processed or litres used.
- Record re-dye and shading additions as separate cost events so they do not distort the original batch cost.
- Close the loop by feeding batch costs back into <a href='http://127.0.0.1:8081/features/costing'>product costing</a> and pricing decisions.
The problem: a batch card is not a cost sheet
A dyehouse batch card lists the recipe, weights and process parameters, but it does not calculate cost. Most plants file the card once the shade is approved and never convert the data into a number that finance can audit. The result is a gap between what the plant thinks it spends and what the P&L shows.
Start with the four cost buckets
Every cost on the batch card belongs in one of four buckets: material, labour, utility or overhead. Label each line before you begin arithmetic.
- Material covers dyes, auxiliaries, salt, soda ash and any other chemical that leaves the store for the batch.
- Labour is the wages of the operator who loads, runs and unloads the machine, including any piece-rate or overtime.
- Utility includes steam, water, electricity, compressed air and effluent treatment.
- Overhead is everything else: machine depreciation, rent, supervision and quality checks.
Fugen ERP product costing enforces this split at the batch level, so the four buckets are never mixed.
Capture actual consumption, not standard rates
Standard rates are useful for quoting, but actual consumption determines the real cost. If the batch card shows 12 kg of dye issued but the recipe called for 10 kg, use 12 kg. If the operator logged 3.5 hours instead of 3, use 3.5 hours. Record the variance separately so the planning team can investigate.
In Fugen ERP, the stock ledger posts actual material issues against the batch, and the payroll module posts actual labour hours. Both feed directly into the batch cost sheet without manual re-entry.
Allocate utilities by measurable drivers
Steam, water and effluent are shared across batches. Allocate them using drivers that reflect actual usage:
- Steam is typically allocated by kilos of fabric processed or by machine-hours, whichever the plant measures.
- Water is allocated by litres used, captured from flow meters or tank dips.
- Effluent is allocated by volume sent to treatment, again from flow meters or tank readings.
- Electricity is allocated by machine-hours if sub-meters are not installed.
Illustration: a jet dyeing machine processes 500 kg of fabric in a 4-hour cycle. The plant’s steam cost is £40 per tonne, and the machine uses 0.8 tonnes of steam per hour. The batch steam cost is 4 hours × 0.8 tonnes/hour × £40/tonne = £128.
Handle re-dye and shading additions as separate cost events
If the batch fails shade and requires a re-dye or shading addition, record the extra material, labour and utilities as a separate cost event. Do not merge it with the original batch cost. This keeps the original cost clean for analysis and ensures the re-dye cost is visible for pricing adjustments.
Fugen ERP allows a single batch card to spawn multiple cost events, each with its own material, labour and utility lines. The system then rolls them up into a total batch cost for reporting.
Build a cost table for quick reference
The following table shows how a typical batch card translates into a cost sheet. Use it as a template for your own plant.
| Cost bucket | Item | Quantity | Unit cost | Batch cost |
|---|---|---|---|---|
| Material | Reactive dye | 12 kg | £8.50/kg | £102.00 |
| Material | Salt | 150 kg | £0.12/kg | £18.00 |
| Labour | Operator wages | 3.5 hours | £12.00/hour | £42.00 |
| Utility | Steam | 3.2 tonnes | £40.00/tonne | £128.00 |
| Utility | Water | 12,000 litres | £0.002/litre | £24.00 |
| Utility | Effluent | 12,000 litres | £0.003/litre | £36.00 |
| Overhead | Machine depreciation | 4 hours | £15.00/hour | £60.00 |
| Total batch cost | £410.00 | |||
Close the loop: feed batch costs back into pricing
Once the batch cost is calculated, feed it back into the product costing module. This updates the standard cost per kilo and per piece, which in turn informs the sales order pricing. If the batch cost is consistently higher than the standard, the planning team can adjust the recipe, negotiate with suppliers or revise the quote.
Fugen ERP posts batch costs automatically to the general ledger, so the P&L and balance sheet always reflect the latest actuals.
What to do next week
Pick one representative batch card from last week. Break it into the four cost buckets and calculate the batch cost using actual consumption. Compare it with the standard cost. If the variance is more than 5 %, investigate the cause and decide whether the standard needs updating or the process needs tightening.
Set up a weekly batch cost review with the dyehouse manager, the cost accountant and the planning team. Use the review to spot trends, not to assign blame. Over time, the plant will develop a library of actual batch costs that can be used for more accurate quoting and better margin control.
