How to say "calculation" in Japanese

Choosing the right word
  • 計算けいさんJLPT N3approx.Common
    noun, suru verb, transitive verbThe default word for calculation in almost any sense: doing arithmetic, working out a total, or reckoning how much something will cost or take. When unsure, this is the safe choice.
    旅行りょこうの総そう費用ひようを計算けいさんしてくれますか。↗
    Can you work out the total cost of the trip?
  • 算出さんしゅつCommon
    noun, suru verb, transitive verbCalculation in the sense of deriving a specific figure or value from data, as when a rate or percentage is worked out and reported. Closer to computing a number than to doing sums.
    年金ねんきんの額がくは原則げんそくとして前年ぜんねんの物価ぶっか変動へんどうにスライドして算出さんしゅつされる。↗
    As a general rule, the pension amount is based on price changes in the previous year.
  • 勘定かんじょうJLPT N3approx.Common
    noun, suru verb, transitive verbCounting or reckoning, especially where money is concerned: adding up what is owed, settling a bill, keeping accounts. For plain arithmetic on paper, 計算 is the more natural choice.
  • 算定さんていCommon
    suru verb, transitive verb, no-adjectiveCalculation that shades into estimation: working out an amount or quantity and fixing it as a figure, the word used when a value is determined rather than simply added up.
    それは300ドルかかると私は算定さんていした。↗
    I calculated that it would cost 300 dollars.
  • 演算えんざんCommon
    noun, suru verb, transitive verbCalculation in the technical sense of an operation: the adding, multiplying, and other processing done in mathematics or by a computer, not the everyday act of working out a sum.

Use 計算 as the all-purpose word for working numbers out; 算出 for deriving a figure from data, 算定 for determining an amount, 勘定 for counting and money matters, and 演算 for mathematical or computer operations.
