1. To ascertain by computation; compute; reckon up arithmetically or by items: as, to calculate interest, or the cost of a house.
2. To make an estimate of; compute by weighing related facts or circumstances in the mind: as, to calculate chances or probabilities.
3. To fit or prepare by the adaptation of means to the end; make suitable; plan: generally in the perfect participle, and frequently (though improperly) in the sense of fitted, without any thought of intentional adaptation.
4. To purpose; intend; design: as, he calculates to do it; he calculates to go.
5. To think; guess. Synonyms and Calculate, Compute, Reckon, Count. Calculate applies to the most elaborate and varied mathematical processes: as, to calculate an eclipse or a nativity. Compute is more applicable to the simpler processes: as, to compute the interest on a note. But mathematicians make the opposite distinction; in their language, to compute means to make elaborate calculations with the art of a person trained to this business. Reckon is essentially the same as compute, but may be simpler yet: as, to reckon interest, or the amount of a bill, or the days to a coming event. To count is to reckon one by one. The figurative uses of these words are not suggested by any comparison of their literal meanings; in them all some mental estimate may be supposed to be made, akin to an arithmetical process. “I reckon that the sufferings of this present time are not worthy to be compared with the glory which shall be revealed in us.” Rom. viii. 18. The use of calculate for reckon in such a case as this is an Americanism. “I count not myself to have apprehended.” Phil. iii. 13. Reckon may be used in such a connection, but not the other two words.
6. To make a computation; arrive at a conclusion after weighing all the circumstances; form an estimate; reckon: as, we calculate better for ourselves than for others; to calculate on (that is, with expectation of) fine weather.
7. To speculate about future events; predict.
8. To suppose or believe, after deliberation; think; ‘guess’; ‘reckon’: as, you are wrong there, I calculate.
9. n. Calculation.
