Morphology

guesstimate = guess + estimate (transparent) = guess + estimate

A verbal blend of 'guess' + 'estimate' whose action meaning (to make an approximate calculation using guesswork) is directly inferred from its components.

Etymology

The verb guesstimate uses the same mix of guess ('a quick idea') and estimate ('a number based on some facts'), so to guesstimate is to give a rough number when you do not have all the information.
