Margin Calculator: Marginal AI

Margin Calculator turns any cost and price into an instant, readable profit verdict. Type your numbers and watch the margin bar split cost, fees, and profit in real time, with gross margin, markup, and net profit laid out like a receipt.

The margin ladder covers gross, sales, contribution, operating, EBITDA, and net margin, plus markup and margin to markup conversion, break-even units and revenue, tax, and discounts. Tap any result to see exactly what it means, so you always know which number you are looking at.

Included in free tier: the full offline calculator with every margin type, break-even math, tax and discount fields, currency switching, and a local history of your recent calculations. No account and no login are required, and your inputs stay on your device.

Included in premium tier: the AI copilot. Describe a product in plain language and it fills the fields for you, apply real marketplace channel fees so the number you see is closer to the number you keep, price a product from a photo with a suggested range, and ask the strategy advisor how to reach a target margin.

Pricing and margin outputs are informational calculations and AI suggestions designed to help with your own pricing decisions, not guaranteed outcomes or professional financial advice. Start free and upgrade whenever you want the copilot.
