When businesses face financial pressure, cost-cutting measures often target essential services, including scale calibration and maintenance.
One of the most common requests we receive is to extend the calibration interval, primarily to satisfy a company’s quality system rather than for operational accuracy. However, the real purpose of calibration is not just to issue a certificate—it is to ensure that weighing scales function accurately and reliably.
But does a small weighing discrepancy really matter? Let’s examine the facts.
At ADF, we conduct both pre- and post-calibration weight checks, and our extensive 40 years of experience consistently reveal that virtually all weighing scales lose accuracy over time. The longer the calibration interval, the more inaccurate the readings become, resulting in increased weight discrepancies. In most cases, inaccuracies range from 1% to 6%, excluding cases of physical damage.
The True Cost of Inaccurate Weighing
Consider the financial implications of just a 1% giveaway in dispatching goods. This loss does not just affect the total cost of goods—it directly impacts the net profit. If a company’s net profit margin is 20%, then a 1% discrepancy in weighing translates to a 5% reduction in net profit.
Similarly, if scales are used for incoming stock checks, inaccurate readings may falsely indicate surplus inventory. This miscalculation can lead to severe operational issues, especially when urgent deliveries depend on correct stock levels.

Why Regular Scale Calibration and Maintenance Is Cost-Effective
The reality is that scale calibration and maintenance do save money—and prevent hidden costs from occurring.
Inaccurate weighing can lead to financial losses, stock discrepancies, regulatory non-compliance, and potential customer dissatisfaction. Ensuring that scales are maintained and calibrated at appropriate intervals is a cost-effective investment. It directly supports business efficiency and profitability.
