Profit Margin Calculator for Small Business
A profit margin is the percentage of total sales revenue that a business retains after paying all costs. It shows how many cents of profit your business keeps from each dollar of sales after accounting for cost of goods sold (COGS) and operational overhead.
Revenue shows cash flow, but margin determines survival. Understanding your gross profit margin versus net profit margin ensures your pricing covers supply costs, marketing, shipping, and taxes while remaining past your break-even point.
Gross Profit Margin Calculator with Cost and Revenue
How to Calculate Profit Margin Percentage:
Gross Margin (%) = ((Revenue - Cost) / Revenue) × 100Markup Formula:
Markup (%) = ((Revenue - Cost) / Cost) × 100How Much Should I Markup My Product for 30% Profit Margin?
The 30% Margin Rule: To achieve a 30% profit margin, you must mark up your product cost by 42.86%, not 30%. For example, if an item costs $70 to produce, pricing it at $100 yields a $30 gross profit ($30 profit / $100 revenue = 30% margin; $30 profit / $70 cost = 42.86% markup).
1. Cost of Goods Sold (COGS): Include raw materials, manufacturing labor, merchant processing fees, and inbound shipping before applying your markup percentage.
2. Overhead & Break-Even Point: Gross margin only accounts for direct product cost. Your final net income must also absorb fixed overhead like software subscriptions, storage, and administrative payroll.
3. Dynamic Price Adjustments: Review wholesale inventory bills quarterly. When supplier rates increase, recalculate your selling price immediately to keep profit percentages stable.
Frequently Asked Questions
What is a good profit margin?
Target margins vary by operating model and industry benchmarks:
- High-Volume / Low Margin (2% - 10%): Grocery stores, automotive dealerships, and wholesale distribution.
- Balanced Retail (10% - 20%): Consumer goods, e-commerce stores, and specialty manufacturing.
- High Margin (20% - 50%+): B2B software, consulting, and professional legal or financial services.
How do you calculate profit margin from cost and selling price?
Subtract your unit cost from the selling price to find your gross profit dollar amount. Divide that profit by the selling price, then multiply by 100. If an item costs $40 and sells for $50, your profit is $10. Dividing $10 by $50 gives a 20% gross profit margin.
What is the difference between profit margin and markup?
Profit margin measures profit relative to the selling price (revenue), while markup measures profit relative to the cost price (COGS). Because cost is lower than selling price for any profitable item, the markup percentage is always higher than the margin percentage.
Is profit margin the same as net income?
No. Net income is the absolute dollar value remaining after paying all product costs, operating expenses, interest, and business taxes. Profit margin is a ratio that shows what percentage of gross sales that net income represents.
