## Introduction

Understanding your profit margin is essential for any business owner. It helps you determine how much money you are making on each product or service you sell. Calculating profit margin can be a bit tricky, but this guide will walk you through the process step by step.

## Why Profit Margin is Important

Profit margin is a key indicator of the health of your business. It shows you how efficiently you are managing your costs and pricing your products. A healthy profit margin also indicates that your business is sustainable and able to weather economic downturns.

## Calculating Gross Profit Margin

Gross profit margin is the percentage of revenue that exceeds the cost of goods sold. To calculate gross profit margin, use the following formula:

(Revenue – Cost of Goods Sold) / Revenue x 100

For example, if your revenue is $10,000 and your cost of goods sold is $5,000, your gross profit margin would be ($10,000 – $5,000) / $10,000 x 100 = 50%.

## Calculating Net Profit Margin

Net profit margin takes into account all expenses, including operating costs, taxes, and interest. To calculate net profit margin, use the following formula:

(Net Profit / Revenue) x 100

For example, if your net profit is $3,000 and your revenue is $10,000, your net profit margin would be ($3,000 / $10,000) x 100 = 30%.
