Hur det fungerar — Gratis Procenträknare

Our calculator solves three types of percentage problems instantly. Here's how each one works:

1

Vad är X% av Y?

Resultat = (X / 100) × Y

15% × 200 = 30

2

X är hur många % av Y?

Resultat = (X / Y) × 100

45 / 180 × 100 = 25%

3

% Förändring

Resultat = ((Y - X) / |X|) × 100

(100-80)/80 × 100 = 25%
