Result
Recommended Mass Tier
—
Enter your inputs and click Calculate.
Estimated Payback Period
—
Time to recover machine cost through avoided labor + defect cost.
5-Year Net Savings (vs current hand assembly)
—
Cumulative labor + defect cost avoided minus machine + electricity + maintenance.
Annual Capacity (recommended tier)
—
Maximum throughput at recommended shift pattern.
Calculation framework — figures use industry-derived inputs (Mass internal commissioning data, BTD ballpoint pen trade statistics, IMS-NL precision-assembly hidden-cost research, Jingsourcing Fenshui factory tour data). Hand-assembly cost includes direct labor plus 33% hidden cost (scrap, rework, training overhead, productivity variation). Mass machine cost assumes mid-range pricing within each tier band ($9K Entry / $25K Mid / $45K Flagship). 5-year operation assumes 250 working days/year per shift, 0.3% machine defect rate, $2K/year maintenance reserve per machine. ROI estimate is directional — your actual result varies by labor market, electricity tariff, and product mix. Request a custom calculation for your specific operation.
This calculator produces directional estimates for procurement evaluation. Specific quotation, lead time, and warranty terms are issued in writing by Mass after configuration confirmation. Brand: Mass / Zhangjiagang Mass Technology Co., Ltd.
