Why is the gap positive below target?

Gap uses the target minus actual convention from V1, so a positive gap means giveaway is under target and a negative gap means it is over. The headline still reports the actual percentage.

Does this check legal minimum net contents?

No. It works from aggregate overfill, so it reports average giveaway. Per-container fill control and a statistical sample are still needed to show that every unit meets its declared net contents.

How does a checkweigher mass convert to volume?

Divide the gram reading by the product density at fill temperature. Water-based products sit near 1.0 g per mL, while emulsions and oils differ, so use the density recorded on the batch record.

What giveaway targets are typical?

Targets depend on filler capability and the label claim size, and tighter targets cut giveaway dollars but raise the risk of short fills. The default 1.5% target keeps a working margin on a 100,000 mL run.

Net Contents Giveaway Calculator

Measure the product given away above the label claim across a fill run and judge it against your target. Both volumes are milliliters of product at fill temperature.

What this calculator does

Overfill giveaway against a target, with allowable overfill, excess and per-container volumes from a fill run.

Formula used

Giveaway = overfill above label claim ÷ label claim volume filled × 100
Allowable overfill = label claim volume filled × target giveaway ÷ 100
Excess overfill = overfill above label claim − allowable overfill
Overfill per container = overfill ÷ containers filled; claim per container = claim ÷ containers filled
Gap to target = target giveaway − giveaway (positive means below target)

Inputs explained

Overfill Above Label Claim: Product above the label claim across the filling run.
Label Claim Volume Filled: Total label claim volume the run should contain.
Target Giveaway: Giveaway percentage the filling line must stay under.
Containers Filled: Containers filled in the run, used for per-container figures.

How to use the result

Best suited to auditing fill line giveaway, setting a tighter giveaway target, checking overfill after a filler tune.
An average giveaway cannot confirm that every container meets minimum net contents. Product temperature changes density, so compare runs measured at the same fill temperature.
