Bag Converting Run Cost Calculator
Estimate the cost of your bag converting run and each thousand bags. Enter the whole bag quantity and separate variable, setup and allocated overhead charges.
What this calculator does
- Calculate bag converting run cost and unit cost from a whole bag count, variable charges, setup and allocated overhead.
Formula used
- Variable converting cost = bags ÷ 1,000 × variable cost per thousand
- Fixed cost = setup cost + allocated run overhead
- Total run cost = variable converting cost + fixed cost
- Cost per thousand bags = total run cost × 1,000 ÷ bags
- Cost per bag = total run cost ÷ bags
Inputs explained
- Bags in Run: Whole bags on the production order or completed run record.
- Variable Cost per Thousand: Job-sheet materials and variable labor per thousand bags.
- Separate Setup Cost: Setup charges excluded from the variable cost entry.
- Allocated Run Overhead: Run overhead allocation excluded from variable and setup charges.
How to use the result
- Best suited to bag run cost Review, Short-Run setup Recovery, converting quote preparation.
- Does not estimate line speed, reject quantity, selling price or profit. Cost per bag uses the entered run quantity; reject losses require a separately reconciled cost basis.
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.
- The producer price index for paper (not a paperboard or container index) stands at 282.266 (BLS, Aug 2026), up 10% from a year earlier. Quotes priced off last quarter's material cost miss this move.
Common questions
- Should I enter bags or thousands of bags? Enter the whole bag count. The variable rate stays in dollars per thousand, and the calculator applies that conversion explicitly.
- Does the variable rate include film? Include film if your cost scope includes it. Keep material, variable labor and other included charges consistent across the runs you compare.
- Where should setup labor go? Enter setup labor in the separate setup cost when it is excluded from your variable rate. Count each charge once.
- Is the result a selling price? No. It is the cost covered by your entries. Add your required profit, selling expenses, freight and other quote terms separately.
