What term describes an assessment of the amount, extent, or worth of something?

The term that best describes an assessment of the amount, extent, or worth of something is "valuations." Valuations typically involve determining the monetary value of an asset, property, or business. This process can require in-depth analysis and consideration of various factors, including market conditions, historical data, and specific circumstances surrounding the item being valued.

While "estimates," "assessments," and "calculations" are related terms, they do not capture the full breadth of what "valuations" entails in the context of establishing worth. Estimates can refer to rough approximations rather than definitive values, assessments can indicate evaluations but often do not imply the financial implications as directly as valuations do. Calculations, on the other hand, focus more on the mathematical aspect, which may not necessarily reflect a thorough analysis of worth. Therefore, "valuations" is the most precise term for an assessment that aims to establish the worth of something.
