Quench Media Cost Calculator

Price consumed quench oil and its separate handling expenses. Enter makeup, discarded gallons and the corresponding purchase, disposal and filtration invoices.

What this calculator does

  • Reconcile quench oil makeup, filtration and disposal expenses over one measured accounting period.

Formula used

  • Makeup expense = consumed makeup gallons × purchase rate
  • Disposal expense = discarded gallons × disposal rate
  • Media expense = makeup expense + disposal expense + filtration expense
  • Expense per makeup gallon = media expense ÷ consumed makeup gallons

Inputs explained

  • Consumed Makeup Oil: Recorded oil makeup consumed during the reconciliation period.
  • Makeup Oil Purchase Rate: Invoice price per US gallon of the consumed oil.
  • Discarded Oil: Waste shipment gallons on the disposal invoice basis.
  • Oil Disposal Rate: Waste handling price per shipped US gallon.
  • Separate Filtration Expense: Filtration invoice excluding oil purchases and disposal charges.

How to use the result

  • Best suited to quench oil expense Reconciliation, filtration contract comparison.
  • This model covers neat oil, not diluted polymer concentrate. Tank capacity and oil cooling performance are not evaluated.

Current U.S. benchmarks

  • Industrial electricity averages 9.77 cents per kWh across the U.S. (EIA, Jul 2026), up 4.7% from a year earlier. Energy-intensive steps carry this directly into unit cost.

Common questions

  • Do I enter the full tank volume? No, enter makeup consumed during the period. The standing tank inventory is not consumed again with every batch.
  • Can discarded gallons exceed makeup gallons? Yes, a disposal shipment may remove oil purchased in an earlier period. Match the disposal volume to its actual invoice.
  • Can I use a polymer bath concentration here? No, this model prices neat oil volumes. A polymer bath requires a separate concentrate and dilution balance.
  • Why is unit expense blank with no makeup? The period may still have filtration or disposal expense, but dividing it by zero makeup gallons would not produce a meaningful unit cost.
