## Key Differences

Estimating generally refers to forming an approximate judgment or calculation of the quantitative aspect of something, such as time, cost, or size. Whereas, evaluating is about thoroughly assessing or determining the value, quality, or importance of an item or situation.

When you estimate, you often use limited data and rely on assumptions and past experience to arrive at a figure that is expectedly close to the actual value. On the other hand, evaluating involves detailed analysis and the consideration of various factors and criteria to make a more comprehensive judgment.

Estimates are typically used in scenarios where an immediate or rough calculation is needed, and precision is less critical. In contrast, evaluation is critical when decisions depend heavily on the outcome's accuracy and depth, such as in strategic business decisions or academic assessments.

Estimating can be more subjective and less formal, often done quickly or on the spot. Evaluate, however, is more systematic and objective, requiring a structured approach to review and analyze information.

While estimates are usually about quantities, evaluating often involves qualitative assessments as well, providing a deeper insight into the subject's characteristics, merits, and demerits.
