Cost per 1,000 Good Joints Calculator
Compare two joining routes with the same cost boundary and accepted-output denominator. Every figure comes from your inputs; the calculator contains no default savings rate, machine price or payback promise.
Process A
Candidate cost inputs
Process B
Alternative cost inputs
Cost per 1,000 good joints = [(equipment + tooling) ÷ useful life + annual labor + utilities + consumables + maintenance + quality loss] ÷ accepted annual joints × 1,000
Input rules for an apples-to-apples comparison
- Anchor both processes to the same product mix and analysis period.
- Count accepted joints after scrap and rework rather than gross strokes.
- Annualize equipment and tooling over the entered useful life.
- Separate operator time from unattended machine time.
- Enter fasteners, welding consumables and electrode care where they apply.
- Capture loaded cycle, changeover and planned downtime in the production model.
- Price inspection, sectioning and destructive tests inside the quality boundary.
- Document exclusions before using the output in a capital request.
- Recalculate when the quotation changes tooling, handling or acceptance scope.
- Use one currency and one accounting basis across both processes.
- Exclude financing or residual value only when both entries use the same rule.
- Revisit accepted output when the product mix or quality threshold changes.
- Save the source for every annual cost beside the calculation.

This result is arithmetic from the entered values. It does not prove joint feasibility, takt, service duty, savings or payback; compare only after the formed stack and quotation boundaries are aligned.
