Key Differences
To calculate means to ascertain or determine by mathematical methods, involving accuracy and precision. Estimating, on the other hand, means to form an approximate judgment or opinion, which might not always be precise but provides a general idea.
When someone needs an exact number, they tend to calculate the value. However, when an approximate or ballpark figure suffices, they will choose to estimate.
While both can be performed mentally, calculating often involves the use of tools like calculators, software, or paper and pen for precise results. Estimating might be based on previous experience, observation, or intuitive judgment without stringent tools.
In professions like engineering, finance, or architecture, to calculate is to determine exact figures, which are critical for final designs or decisions. To estimate in these fields means to provide provisional figures that might be subject to change.
Calculations, especially complex ones, might take longer due to their need for precision. Estimations, being rough approximations, are often quicker.
