Does accepted output include reworked tubes?

Yes, if they were finally accepted. Include their rework costs in the run material, conversion or fixed totals as appropriate.

What belongs in the conversion rate?

Use the loaded production cell rate for the staffing and machine configuration observed. Include direct labor and allocated machine overhead once.

Where do scrap credits belong?

Subtract the recorded net credit from run material cost. Keep hauling charges in that net credit or another listed cost without counting them twice.

Can I use this before the run?

Yes, with an approved expected accepted count and a complete estimated job cost. The result then depends on those estimates rather than measured run performance.

Tube, Pipe & Profile Forming calculator

Cost per Formed Tube Calculator

Find the manufacturing cost carried by each accepted formed tube. Enter completed run counts, issued material cost, loaded production cell time and the separate setup allocation.

What this calculator does

Allocate actual run manufacturing costs across accepted formed tubes.

Formula used

Conversion cost = production cell hours × loaded conversion hourly cost
Total run cost = material cost + conversion cost + fixed setup and tooling
Cost per accepted tube = total run cost ÷ accepted tubes
Final accepted share = accepted tubes ÷ total formed tubes × 100
Per-tube component cost = run component cost ÷ accepted tubes

Inputs explained

Total Tubes Formed: All formed tubes from the completed run, including rejects.
Accepted Formed Tubes: Accepted output count from the completed run.
Run Material Cost: Issued material cost less recorded net scrap credits.
Production Cell Hours: Observed production cell time assigned to this run.
Loaded Conversion Hourly Cost: Cell rate including machine, direct labor and allocated overhead.
Fixed Setup and Tooling Cost: One-time setup and tooling allocation outside production cell costs.

How to use the result

Best suited to completed run Costing, reject cost review.
Does not predict reject rates or apply a customer billing factor. Freight, taxes, selling costs and profit are excluded unless entered in scope.

Current U.S. benchmarks

The producer price index for steel mill products stands at 381.162 (BLS, Aug 2026), up 23.4% from a year earlier. Quotes priced off last quarter's material cost miss this move.
