What does miscalculating mean?
Miscalculating is the present participle of “miscalculate,” meaning to calculate or estimate something incorrectly. It describes an error in numerical reasoning, such as underestimating costs, overestimating demand, or arriving at an inaccurate total. The word can refer to a deliberate mistake, but more often it simply identifies an inaccurate calculation or judgment, without implying dishonesty. In everyday use, “miscalculating” may also describe a person or organization whose repeated decisions show poor judgment, although “miscalculate” is generally the more direct verb. The construction is especially common in reporting and business contexts, where financial forecasts, projections, risks, and expectations are being assessed. It is a useful word because it identifies not merely a discrepancy in a result but the faulty calculation or assessment that produced it. The prefixed form follows the ordinary grammatical pattern of English verbs: “miscalculate,” “miscalculates,” “miscalculated,” and the present participle “miscalculating.”

Where does miscalculating come from?
The word is formed from the prefix “mis-,” meaning wrongly, and “calculate.” “Calculate” comes through Latin from “calculus,” a term associated with pebbles used for counting, while the Latin verb “calculare” originally referred to counting with such pebbles. The same Latin root also underlies “calculation,” “calculator,” and the mathematical adjective “calculable.”
