Recorded Run Cost per 1,000 Litres

Use actual costs and accepted filtered volume from one completed run. Enter all costs in the same currency. This worksheet does not predict bag life, filtration quality or savings.

Formula: (bag + labour + downtime + disposal cost) ÷ accepted litres × 1,000. Exclude rejected volume. Compare runs only at the same outlet-quality requirement and with the same cost boundaries. Add energy or cleaning costs to your wider assessment if relevant; they are outside this worksheet.

Inputs must be finite, non-negative and at most 1,000,000,000,000 per field; accepted volume must be greater than zero. These are calculator limits, not product limits.
