My 11th grade daughter asked me how to calculate retail mark up percentages, I would appreciate any help with this question.

Thank you,
John

Hi John,

If the mercant bought an item for $10.00 and sold it for $14.00 then the markup on this item is $4.00. As a fraction of cost the markup is 4/10. To make this a percentage multiply by 100 to get (4/10)100 = 40%. Thus the percentage markup on this item is 40%.
   For another example suppose the merchant bought the item for $35.12 and she sold it for $49.95 then the markup is $49.95-$35.12=$14.83 As a fraction of her cost the markup is 14.83/35.12 = 0.422. Multiplying by 100 gives a markup of approximately 42%.

Cheers
