Ausrechnen

Ausrechnen is a German verb meaning to calculate, to work out, or to compute a numerical result. It is used when a precise value is obtained by arithmetic, such as prices, quantities, times, or probabilities. The verb is separable: in the present tense you say ich rechne das aus, du rechnest das aus, er rechnet das aus; in the past tense the perfect is formed with haben, for example ich habe das ausgerechnet.

Etymology and usage notes: ausrechnen comes from the prefix aus- (out, complete) combined with rechnen (to reckon, calculate). The expression often stresses arriving at a final figure through explicit calculation, rather than a rough estimate. It appears in contexts ranging from daily budgeting to problem solving in math.

Examples: Ich muss noch ausrechnen, wie viel das kostet. Könntest du bitte ausrechnen, wie lange die Fahrt dauert? Wir haben die Gesamtsumme ausgerechnet. Das Produkt ist ausgerechnet teurer geworden.

Differences and related terms: Ausrechnen emphasizes the completion and the exact result of a calculation. Similar verbs include berechnen (to calculate, often focusing on the method or the act of computing) and rechnen (to calculate in a general sense). Calculations can also involve estimation or approximation, for which other terms may be used.
