Production Capacity Calculator

Theoretical capacity assumes 100% uptime and perfect performance. Effective capacity applies OEE to account for downtime, speed losses, and quality losses. Effective capacity is what you can realistically achieve in daily operations.

Capacity per machine = (Available time in seconds) ÷ (Cycle time per unit). Available time = Shifts × Hours per shift × 3600 × (1 - downtime%). Multiply by number of machines for total capacity.

For planning purposes, use your current actual OEE, not a target. World class OEE is 85%, but many plants operate between 60–75%. Using an unrealistic OEE for capacity planning leads to missed delivery commitments.

This calculator uses 260 working days (52 weeks × 5 days). Actual numbers vary by industry. Adjust for holidays (typically subtract 10–15 days for US manufacturers) or use 250 days as a conservative estimate.
