I made this excel file that is basically a calculator. It needs to create a Total price after fees, profit and supplier cost. Most profit margin calculators have you add a percentage for profit... this is not what I want. I have a hard dollar amount. You must know that the entire transaction includes supplier cost, profit and fee. The fee is charged from the total of the Transaction. I do not want to brute force until I find a total price that equals 5 bucks in profit. For instance... Supplier Cost : $50 Profit I want to make : $5 10% Transaction Fee : ? Total to charge : Some unknown without brute force. Currently you put the Supplier cost and a GUESS of the Total price. And keep adjusting while watching your profit until it gets to $5 bucks. So here is an example.... Enter Supplier cost..... ___$50___ Enter Profit to make.... ___$5____ With this info I need it to spit out the total to charge so that the money left in the account is enough to *pay supplier *Pay transaction fee *And exact profit of $5 is what is left. In this case... *Fee is: $6.11 *Total price is $61.11 Customer is charged 61.11 and we pay a transaction fee and a profit. It should zero out. Does this make sense?
