Costco Gold Profit Calcutor

This calculates the estimated profit given: 1) the current cost of the gold bars at Costco, 2) your selling price, 3) the reseller’s cut %, 4) the cashback you get on the credit card used for the purchase, and 5) an optional 2% cashback if you have a Costco Executive Membership and haven’t reached the $62.5k annual cap. (Disclaimer: use this calculator at your own risk — you should manually verify the calculator is working according to your expectations.)

The formula for this calculator is currently as follows:

var total_profit = nbars * (barcost * (ccrate + emrate) / 100 - (barcost - sellprice * (100 - rcutrate) / 100));
