Estimate vs. Predict: What's the Difference?
Edited by Harlon Moss || By Janet White || Updated on October 4, 2023
"Estimate" means to make an approximate calculation or judgment, while "Predict" involves forecasting a future event or outcome based on evidence or reasoning.
Key Differences
Both Estimate and Predict revolve around projecting or deducing something that isn't immediately certain. "Estimate" commonly deals with determining approximate numbers, values, or extents based on available data. In contrast, "Predict" leans towards foretelling specific outcomes, events, or trends based on insights, patterns, or evidence.
In their everyday application, when you Estimate, you're trying to gauge or measure something without exact precision. It's more about reaching a general understanding. On the other hand, when you Predict, you're anticipating a certain outcome or event, using the data, trends, or patterns you've observed.
The origins of the words also offer insights. Estimate is derived from the Latin 'aestimare', meaning to value or appraise. This highlights its association with valuation. Predict, however, comes from the Latin 'praedīcere', meaning "to foretell," emphasizing its forecasting nature.
From a grammatical standpoint, both Estimate and Predict can function as verbs. However, "Estimate" can also be a noun, as in "an estimate of the costs". "Predict" remains primarily verb-centric in its usage.
In specialized fields, Estimate often has a connotation of calculated approximations, especially in areas like construction, finance, or statistics. Predict, conversely, has strong ties to fields that focus on forecasting, such as meteorology, finance, and even machine learning.

Yes, scientists often predict outcomes based on research.
Which word suggests more precision, Estimate or Predict?
"Predict" often suggests a more specific forecast, while "Estimate" is about approximation.
Does an Estimate need evidence?
It's based on available information, but isn't as evidence-centric as a prediction.
Can you Predict the weather?
