The calculation of price changes in Zetsy are the following:
For 10% off it is straightforward:
Price = (curPRICE - ((NumPercentage / 100) * curPRICE) where NumPercentage is amount off, for instance 10%
For a 10% price increase it is NOT as straight foward. The equation used is:
price = (curprice / (1 - (NumPercentage / 100))
Why the difference?
For most people they put on a sale for lets say 20% off. For a $10 item the prcie become $8. To reverse this sale the natural inclination is to state a 20% increase. This leads to a value of $9.60 - e.g we are not where we were.
The equation that Zetsy uses puts us back at $10, but if you really wanted to increase prices by 20% it is wrong.
I will entertain ways around this if anyone has suggestions. I can add another option for % increase and label it a way that makes sense (and hopefully
For now you can do a little math and calculate the difference:
For a 20% increase a value of 16.666 needs to be entered
For a 10% increase a value of 9.0909 needs to be entered.
