You cannot.
Selling price = Cost of goods sold + Gross profit percentage on sales
Cost = Selling Price - Gross Profit By using this formula or method easily we can get the selling price of the product
Selling Price times (1 - Gross Profit % as a decimal) So, if your selling price is $20 and your gross profit is 30%: 20 x (1 - .3) = 20 x .7 = $14
Simple!just subtract your cost price from your selling price.
Multiply the cost price by the profit margin plus 100%. SP=CP*(1+PP)
multiply the full price by 0.2 That is the amount of the discount
Gross price-expenses=net price
cost price = selling price - profit
The formula is Gross = Net * ( Tax rate / 100 + 1) You can also use this site to calculate Gross/Net Price. http://jumk.de/bank-formulas/gross-net.shtml
gross profit
The higher the gross margin the more profit you can make. Gross margin is the difference between cost and original sell price of a product. it is you the original conceived profit. Obviously the higher the gross margin the more profit possible. (That is as long as a customer will pay that price!!)
let the cost price =X sell price=cost +profit selling price=x+profit
