Foam, Insulation & Cushioning Products calculator

Chemical Mix Cost Calculator

Cost a two-component foam batch from the actual amounts charged. Enter supplier-approved component masses, invoice prices and separate fixed mixing charges.

What this calculator does

  • Calculate the cost of weighed foam components and fixed batch charges, with a transparent cost per charged pound.

Formula used

  • Chemical cost = A mass × A price + B mass × B price
  • Total mix cost = chemical cost + fixed mixing charges
  • Charged mass = A mass + B mass
  • Blended purchase cost = chemical cost ÷ charged mass
  • Cost per charged pound = total mix cost ÷ charged mass

Inputs explained

  • Charged Mass of A: Weighed as-supplied component A from your approved batch sheet.
  • Purchase Cost of A: Landed invoice cost per pound of as-supplied component A.
  • Charged Mass of B: Weighed as-supplied component B from your approved batch sheet.
  • Purchase Cost of B: Landed invoice cost per pound of as-supplied component B.
  • Fixed Mixing Charges: Batch setup, purge and quality-control charges excluding component costs above.

How to use the result

  • Best suited to two-component batch costing, component supplier price review, smaller order scope.
  • Does not determine mix ratio, cured density, expansion or saleable yield. Separate additives must already be included in the purchased components. Input ceilings are computational safeguards, not batch-size recommendations.

Current U.S. benchmarks

  • The producer price index for plastic resins and materials stands at 280.569 (BLS, Aug 2026), up 6.6% from a year earlier. Quotes priced off last quarter's material cost miss this move.

Common questions

  • Does this choose my foam mix ratio? No. Enter weighed amounts from the supplier's approved formulation; changing the ratio to reduce cost can change the reaction and finished properties.
  • Are these cured foam pounds? No. Both masses are the liquid components as supplied and charged. Use measured saleable output separately to determine finished-product cost.
  • Where do catalysts and blowing agents go? Include them only if they are already part of the purchased components and their prices. This two-component model does not separately cost additional ingredients.
  • Why does a smaller batch cost more per pound? Unchanged setup charges are spread over fewer charged pounds. Compare actual smaller component quantities while retaining the approved ratio.
