Profit & Loss Calculator

Calculate profit or loss amount and percentage for any transaction.

What is Profit & Loss Calculator?

A Profit and Loss Calculator helps business owners, traders, and investors determine the profit or loss on any transaction by comparing the cost price (what you paid) to the selling price (what you received). It calculates both the absolute dollar value of profit or loss and the percentage gain or loss relative to the original cost, giving a complete financial picture of any commercial transaction.

This tool serves a broad audience: retail shop owners calculating margins on products, stock market traders assessing trade performance, e-commerce sellers evaluating SKU profitability, real estate investors calculating returns on property sales, and small business owners reviewing monthly financial performance. The percentage view is often more informative than the absolute figure — a $500 profit means very different things on a $1,000 investment versus a $50,000 investment.

Beyond individual transactions, understanding profit and loss is the foundation of business viability. A business that consistently prices products without understanding margins eventually faces cash flow crises, even if sales volume is high. This calculator makes margin analysis accessible to anyone, from first-time entrepreneurs to seasoned financial analysts doing quick back-of-envelope checks.
