Filling Line Speed Calculator

Work out filling line speed instantly with clear inputs, formula shown and shareable results.

About Filling Line Speed Calculator

Rated line speed must exceed the average rate by the reciprocal of line efficiency, because the line loses time to changeovers, jams and cleaning. Dividing by the number of filling heads gives the cycle time each head must achieve, which is the figure that determines whether the fill valve and product viscosity can keep up.

Formulas

Required speed

Required rate = target output / (shift hours x 60 x line efficiency)

Per head

Rate per head = required rate / heads; cycle time = 60 / rate per head

Worked example

With the default values below, Filling Line Speed Calculator returns Required Line Speed of 64.10. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why specify a machine faster than average demand?

Because efficiency is never 100%. A filler rated at exactly the average rate can never recover from a stoppage and will always miss the shift target.

What limits fill cycle time?

Product flow through the valve, foaming, headspace de-aeration and container indexing. Viscous or foaming products often cap head cycle time well below the mechanical limit.
