How do you calculate fill weight giveaway?

Subtract the declared weight from the average fill, then divide by the declared weight. 16.18 oz against 16 oz is 0.18 oz, 1.125%. Over 12,000 packages that is 135 lb, 189.00 at 1.40 a pound, the Fill Weight Giveaway calculator's own example.

What is the lowest safe average?

The declared weight plus your sigma cover times the run's standard deviation: how far above the label the average has to sit to keep light packages above it. With a 0.04 oz spread and a cover of 2 it is 16.08 oz for a 16 oz bag. The cover is your own policy.

What is avoidable giveaway?

The average fill above the lowest safe average, times the packages, priced at the product cost. It is the giveaway the run's spread did not need; lowering the target by that much would have saved it.

Should I just lower the target to cut giveaway?

Reduce the spread of fill weights first, then lower the target. Lowering the target with the same spread risks underweight packages; a tighter spread lets the target come down safely.

Does it check compliance with net content rules?

No. It measures giveaway and its cost. Check underweight packages and lot averages against the net content rules for your market separately.

Does the workbook use macros?

No. It is a plain .xlsx with ordinary formulas, tables and native charts. The Verify sheet re-checks the formulas against fixed test runs and shows Self-check: PASS.

Fill Weight Giveaway Excel Template

Giveaway = (average fill − declared weight) ÷ declared weight, and its cost = overfill per package × packages ÷ 16 × cost per pound. Log every filling run and see its giveaway against the product's target, what it costs, and how much of it the run's spread does not need.

Free, and a plain .xlsx with no macros to enable. A CSV with live formulas and a printed how-to guide come with it.

Overview

This fill weight giveaway template is a working Excel workbook for packaging and production managers and quality and process engineers. Each filling run is one row with its product, packages, and the average and standard deviation of net weights from the checkweigher. The product list on Setup gives the declared weight, the product cost per pound and the target giveaway. The workbook gives each run's overfill in ounces, as a share, in pounds and in money, and, with your sigma cover, the lowest average the run's spread allows: anything above it is giveaway the spread does not need. Weights are in ounces and cost per pound, as in the calculator. It ships with twelve runs of three products on two lines at a fictional snack packer, so every tile and chart is filled in when you open it.

In the example a run of 12,000 trail mix bags averaging 16.18 oz against 16 oz gives away 1.125%, 135 lb, 189.00 at 1.40 a pound, near its 1.0% target. After the filler was serviced the spread fell from 0.06 to 0.04 oz, so at two standard deviations the bags could average 16.08 oz, but the target was not reset: the next two runs averaged 16.21 and 16.19 oz and gave away 258 that the spread did not need. Once the target was lowered the giveaway fell to 0.625%. Across the twelve runs giveaway cost 2,410, of which 553 was avoidable.

The lowest safe average is a planning figure from your own sigma cover, not a test of net content rules. The download is a plain .xlsx with no macros. A CSV with live formulas is also included for other tools; the dashboard, charts, dropdowns and self-check are in the .xlsx.
