How to Use This Tool
Enter your total revenue, cost of goods sold (COGS), operating expenses, and income tax rate. Select the reporting period (monthly, quarterly, or yearly) to match your business cycle. Click 'Calculate Margin' to see a detailed breakdown of your profitability.
Formula and Logic
The tool calculates Gross Profit (Revenue - COGS), Operating Profit (Gross Profit - Operating Expenses), and Net Profit (Operating Profit - Income Tax). Net Profit Margin is (Net Profit / Revenue) * 100. This follows standard accounting principles for small businesses and e-commerce operations.
Practical Notes
- For e-commerce sellers, include platform fees, shipping costs, and payment processing fees in operating expenses.
- A net profit margin above 10% is generally healthy for most small businesses; below 5% may indicate pricing or cost issues.
- Use quarterly or yearly periods for strategic planning; monthly for cash flow management.
- Consider trade terms like bulk discounts or supplier negotiations when estimating COGS.
