Business calculator
Editor
Enter cost, selling price or target pricing goals, quantity, and optional adjustments in one calm layout. The profit, margin, markup, and pricing insights update instantly as you compare scenarios.
The calculator keeps the core pricing inputs visible up front, makes the target mode clear, and leaves optional adjustments in the same card so the workflow stays simple for beginners.
Pricing mode
Choose whether you want to analyze an existing price, solve for a target margin, or solve for a target markup.
Pricing inputs
Start with the unit cost and quantity, then either enter your current selling price or choose the margin or markup target you want to hit.
Margin shows profit as a share of selling price, while markup shows profit as a share of cost. Both update from the same unit economics.
Optional adjustments
Use discount and fixed costs for a more realistic pricing picture without mixing them into the core unit margin and markup definitions.
Discount changes the realized selling price before margin is calculated. Fixed costs reduce adjusted total profit, but they do not change the per-unit margin or markup percentages.

How it works
A profit margin calculator helps you understand whether a price leaves enough room between cost and selling price. It turns basic pricing inputs into practical outputs like profit per unit, total profit, margin, markup, and required selling price.
Profit per unit is the realized selling price minus cost per unit. Total profit scales that same unit result across the quantity you enter. If you add fixed costs, the calculator also shows an adjusted total profit so you can see how overhead changes the bigger picture.
Profit margin is profit as a percentage of selling price. If a sale brings in $40 and keeps $15 of profit before fixed costs, the margin is 37.5%. Margin answers the question, “How much of each sales dollar do I keep as profit?”
Markup is profit as a percentage of cost. If the cost is $25 and the profit is $15, the markup is 60%. Markup answers a different question: “How far above cost am I pricing this item?”
Margin and markup are related, but they are not the same. Margin uses selling price as the denominator. Markup uses cost as the denominator. That is why a 40% margin does not mean a 40% markup, and why this calculator displays both side by side.
Quantity scales the total revenue and total profit. Discount reduces the realized selling price before margin is calculated. Fixed costs reduce adjusted total profit without changing the unit margin or markup math. Results are estimates based only on the values you enter.
