Cost(Margin%) <> Price(Markup%) Calculation Shortcut

Cost(Margin%) and Price(Markup%)

For when you [know only the Margin or Markup] there is a very short way to calculate this on either ways.

For example:

If you want the Cost(Margin%) for 16.67% What is the Price(Markup%) ?

I.Steps: 16.67 [1/x] [EEX] [CHS] 2 - [1/x] Result Markup% = 20%

The other way around if you want Price(Markup%) for 20% What is the Cost(Margin%) ?

II.Steps: 20 [1/x] [EEX] [CHS] 2 + [1/x] Result Margin% = 16.67%

The only thing to make sure is when you calculate

Margin to Markup use Minus (-)
Markup to Margin use Plus (+)

This short step can be implement to Programmable Calculator.
