Profit & Loss Percentage Calculator
Calculate profit or loss percentage from buy and sell prices.
Whether you're flipping items, trading shares or running a shop, the core question is the same: did this deal make or lose money, and by what percentage? Profit and loss percentage is always figured against the buying price, which is where people slip up by dividing by the wrong number.
Enter what you paid and what you sold for, and this calculator returns the profit or loss as both an amount and a percentage of your cost. A positive result is profit; a negative one is loss. It's the quick check for resale margins, trade outcomes and pricing decisions.
