Margin calculator helps you find your profit margin or how much you should sell your goods for. It’s a must have for any business person!.Margin calculator does one simple thing – lets you calculate any of the main variables in the sales process – cost of goods sold (how much you paid for the stuff that you sell), profit margin, revenue (how much you sell it for) and profit. In general, your profit margin determines how healthy your company is – with low margins you’re dancing on thin ice and any change for the worse may result in big troubles. High margins mean there’s a lot of room for errors and bad luck.

Calculate the gross margin percentage, mark up percentage and gross profit of a sale from the cost and revenue, or selling price, of an item. For net profit, net profit margin and profit percentage, see the Profit Margin Calculator.

* Revenue = Selling Price

**Margin Formulas/Calculations:**

- The formula for gross margin percentage is as follows:

gross_margin = 100 * profit / revenue (when expressed as a percentage).

- The profit equation is:

profit = revenue – costs,

so an alternative margin formula is:

margin = 100 * (revenue – costs) / revenue.

- Now that you know how to calculate profit margin, here’s the formula for revenue:

revenue = 100 * profit / margin.

- And finally, to calculate how much you can pay, given your margin and revenue (or profit), do:

costs = revenue – margin * revenue / 100

**Example**

Margin = 100 x (200-100) / 200

= 50

Profit = 200 – 100

= 100
