Kam skirta
Anyone checking a discount, a grade or a change between two values.
Kaip veikia skaičiavimas
X% of Y = X/100 × Y. ‘X is what % of Y’ = X/Y × 100. Change = (new − old) / old × 100.
Formulė
part = p/100 × whole; percent = part/whole × 100; change = (new − old)/old × 100
Prielaidos
- Numbers are exact as entered.
- Change uses the first value as the base.
Apribojimai
- Does not handle successive discounts unless you chain the results yourself.

DUK
- Is percentage change the same as percentage points?
- No. A rate moving from 10% to 12% is 2 percentage points and a 20% relative change.
