Learn how to calculate profit margin for any product or service
Calculate profit and profit margin
Enter a selling price and your cost to compute two core metrics: profit in dollars and profit margin as a percentage of revenue. This helps you validate whether a price point supports your targets before you launch a product, send a quote, or run a promotion. It’s built for sales, retail, ecommerce, and consulting teams that need quick, consistent profitability checks.
Include additional costs for more accurate pricing
Add optional expenses like shipping, marketplace fees, payment processing, packaging, or overhead to get a clearer view of true profitability. If you leave additional costs blank, the calculator treats it as zero, so you can move fast when you do not have every detail. This is useful for ecommerce operators and service businesses comparing scenarios across channels and deal sizes.
Compare pricing scenarios before you commit
Use the calculator to test multiple selling prices against the same cost structure to find a margin that fits your goals. It’s helpful when deciding between discount levels, bundles, or tiered service packages, since you can see how each option affects profit and margin. Teams can use the results to align on guardrails for quoting and promotions.
Validate profitability for listings, quotes, and campaigns
Apply the output to day-to-day decisions like setting a product listing price, reviewing a wholesale offer, or estimating the impact of ad-driven sales. Because the tool returns a simple two-line result with rounded values, it’s easy to copy into a spreadsheet, a proposal, or internal documentation. This supports faster approvals and fewer pricing mistakes.
