Stabilise conditions
Temperature, air entrainment, head pressure, product level and supply pressure can alter the delivered dose.
Free cost calculator
Product overfill and giveaway cost calculator.
Estimate the annual litres and product cost tied up in average overfill, then model the potential saving from a controlled reduction.

Commercial model
Convert millilitres per pack into annual product value.
The result helps quantify why repeatability, calibration and stable product conditions matter. It does not set a legal fill target and must not be used as a substitute for a compliant quantity-control system.
- Use measured average overfill from a representative production sample.
- Enter the real marginal product cost per litre.
- Model a realistic improved average, not zero.
- Review the result alongside fill variation and legal requirements.
Control the process
Cost reduction should come from lower variation, not unsafe underfilling.
For packaged goods in Great Britain, quantity control and records may be relevant. The operating target should be set by a competent person using the current rules and measured process capability.
Measure variation
Track more than the average. Use representative checks to understand spread, drift and changeover effects.
Maintain the machine
Worn seals, valves, tubing, nozzles and loose settings can increase both variation and giveaway.
Regulatory note: GOV.UK explains that packaged-goods rules protect against short measure and require suitable checking equipment and records. See the UK filling machinery compliance guide and obtain competent advice for your product and process.
Calculation method
How the product-giveaway model is calculated.
Annual giveaway volume equals annual pack count multiplied by average overfill per pack, converted from millilitres to litres. Product cost is the resulting volume multiplied by the entered cost per litre.
| Current giveaway litres | Annual packs × current average overfill in ml ÷ 1,000 |
| Current giveaway cost | Current giveaway litres × product cost per litre |
| Modelled recovered volume | Annual packs × (current overfill − improved overfill) ÷ 1,000 |
| Modelled annual saving | Recovered volume × product cost per litre |

FAQs
Product-overfill calculation questions.
A small excess on every pack becomes a large annual volume when multiplied across production, especially for high-value products.
No. The operating target must account for process variation and the applicable quantity-control rules. The calculator only models the commercial effect of changing average overfill.
No. It calculates product volume and product cost only, using the assumptions entered.
Use a capable filling process, representative sampling, stable product conditions, calibration, maintenance and a control plan that meets the applicable legal requirements.
