# Calculation vs. Estimation: What's the Difference?

Edited by Sumera Saeed || By Sawaira Riaz || Published on October 10, 2023
Calculation is the process of solving mathematical problems to find an exact answer, while estimation is a method to approximate a value, giving a quick, close-enough answer.

## Key Differences

Calculation and estimation serve distinct roles in numerical problem-solving. Calculation implies precision, involving methods or operations to find an exact value or answer, typically using algorithms or formulas. Conversely, estimation involves approximating or judging a value that is likely close to the true value but not exact, making it useful when exactness is not crucial or when quick judgment is needed.

Calculation is an integral part of mathematics, science, and engineering, enabling the derivation of precise and reliable results, which is essential when accuracy is paramount. Estimation, on the other hand, is commonly employed in everyday scenarios or when dealing with complex problems where achieving an exact answer is impractical, providing a swift and near-accurate solution.

When a calculation is performed, the result is definitive and can be verified using mathematical rules or by repeating the process. In contrast, estimation results are inherently uncertain, cannot be precisely verified, and may vary based on different individual’s judgments or the method employed to approximate.

A calculation can be time-consuming, especially when dealing with intricate problems or large datasets. In contrast, estimation often prioritizes time-efficiency over precision, making it a suitable approach when a general understanding or a range is sufficient.
