How do you calculate line efficiency on a packaging line?

Divide the good containers packed as finished goods by the line's rated capacity for the scheduled runtime, then multiply by 100. With 43,000 good containers against a 50,000 rated capacity you get 86% line efficiency.

What is a good line efficiency for a bottling or canning line?

World-class packaging lines run 85-95% efficiency against rated speed for a stable, single-SKU run. At 86% you are in a respectable band but two points under an 88% target, so there is recoverable throughput.

What is the difference between line efficiency and OEE?

OEE multiplies availability, performance, and quality separately. This line efficiency figure is a direct output-to-rated-capacity ratio, simpler to compute shift to shift but less diagnostic about which loss bucket is hurting you.

Why is my line efficiency below target?

The gap is good product you could have packed at rated speed but did not, lost to changeovers, micro-stops, slow-downs, jams, and rejects. The 2-point gap in the example is roughly 1,000 containers of lost throughput.

Does line efficiency account for rejects?

Yes, because only good containers packed as finished goods go in the numerator. Rejected and damaged containers never count toward efficiency, so a quality problem pulls the number down just like a speed problem.

How do I improve line efficiency?

Find the largest loss against rated speed first. If short stops dominate, attack the filler and capper; if changeovers dominate, run SMED. Recovering the 2-point gap on a 50,000-capacity run adds about 1,000 saleable containers.

Bottling, Canning & Filling Lines calculator

Line Efficiency Calculator

Line efficiency measures how much good finished product your packaging line produced against what it should have produced at rated speed for the scheduled runtime. Plant managers and packaging engineers use it as the headline performance number because it folds speed losses, micro-stops, and reject rates into one figure tied to the line's nameplate capacity. Where fill rate asks whether you made the order, line efficiency asks whether you made it as fast as the equipment was designed to. It is the metric most directly tied to capital utilization and the cost per case packed.

What this calculator does

Measure how much of the rated bottling or canning line capacity became good finished containers after stops, speed losses, and rejects.
a bottling or canning line is being reviewed against its planned shift capacity and daily efficiency target
It computes good containers packed as finished goods as a percentage of the line's rated capacity for the scheduled runtime, plus the point gap to target.

Formula used

Line efficiency = good containers packed as finished goods ÷ rated line capacity for the scheduled runtime × 100
Gap to target = target - line efficiency

Inputs explained

Good containers packed as finished goods:
Rated line capacity for the scheduled runtime:
Line efficiency target for the run:

How to use the result

Use it for any run where you want to judge throughput against the line's design speed rather than against a possibly soft schedule.
Rated capacity must reflect the actual SKU and container size; using a generic nameplate speed for a slower SKU makes efficiency look artificially low.
