What is one OEE point worth on your line?

OEE points are abstract until they're euros. This calculator converts an OEE improvement into extra good units and annual margin — the number a CFO signs off on.

Inputs

Scheduled production hours per year

3-shift ≈ 6,000–7,500 h; 2-shift ≈ 4,000

Ideal output per hour (units)

Nameplate/best demonstrated rate

Margin per good unit (€)

Contribution margin, not price

Current OEE (%) · 62

World-class ≈ 85%; typical plants run near 60%

Improvement target (OEE points) · 5

ML-driven programs commonly deliver 3–10 points

The math. Extra good units = scheduled hours × ideal rate × (OEE gain ÷ 100). Annual gain = extra units × margin/unit. Assumes the market absorbs the extra output; if not, value shifts to cost-per-unit reduction.

Benchmarks: world-class OEE ≈ 85%; typical measured plants run near 60%; unmeasured lines often discover they're at 40–50% when instrumented. One point of OEE on a constrained line is pure margin.
