Revenue, Expenses, and Profit: The Three Numbers Every Entrepreneur Must Know
Every business, from a lemonade stand to a Fortune 500 company, comes down to three numbers:
- Revenue: Money coming in from sales
- Expenses: Money going out to run the business
- Profit: What's left after expenses (Revenue minus Expenses)
The Formula
Profit = Revenue - Expenses
If revenue is $5,000 and expenses are $3,000, profit is $2,000.
If revenue is $5,000 and expenses are $6,000, the business has a loss of $1,000.
Types of Expenses
To be deductible for tax purposes, business expenses must generally be both "ordinary" (common and accepted in your trade or business) and "necessary" (helpful and appropriate for your trade or business) [1].
| Expense Type | Examples | Fixed or Variable | | :--- | :--- | :--- | | Cost of goods sold | Materials, inventory, production labor | Variable | | Operating expenses | Rent, utilities, insurance, software | Fixed | | Marketing | Advertising, content, promotions | Variable | | Labor | Employee wages, contractor fees | Fixed or Variable | | Taxes | Income tax, payroll tax, sales tax | Variable | | Interest | Loan payments | Fixed |
Note: Business owners may also be able to deduct the cost of certain property through depreciation [8].
Revenue vs. Profit: The Critical Distinction
Many new entrepreneurs confuse revenue with profit. A business with $100,000 in revenue sounds successful — but if expenses are $95,000, profit is only $5,000.
| Business | Revenue | Expenses | Profit | | :--- | :--- | :--- | :--- | | Business A | $100,000 | $95,000 | $5,000 | | Business B | $50,000 | $30,000 | $20,000 | | Business C | $200,000 | $210,000 | -$10,000 |
Business B has the lowest revenue but the highest profit. Business C has the highest revenue but is losing money. Profit, not revenue, determines success.
Profit Margins
Profit margin is profit expressed as a percentage of revenue:
Profit Margin = (Profit / Revenue) x 100
| Business | Revenue | Profit | Profit Margin | | :--- | :--- | :--- | :--- | | Software company | $100,000 | $80,000 | 80% | | Consulting firm | $100,000 | $60,000 | 60% | | Restaurant | $100,000 | $10,000 | 10% | | Grocery store | $100,000 | $3,000 | 3% |
Different industries have different typical margins. Software has high margins (low cost to produce additional units). Restaurants have low margins (high food and labor costs).
How to Increase Profit
There are only three ways:
1. Increase Revenue
- Raise prices
- Sell more to existing customers
- Find new customers
- Add new products or services
2. Decrease Expenses
- Negotiate lower supplier costs
- Reduce overhead (rent, utilities)
- Automate to reduce labor costs
- Cut unnecessary spending
3. Do Both
The most successful businesses increase revenue while controlling expenses — widening the gap between the two.
The Break-Even Point
Break-even is the point at which total cost and total revenue are equal, meaning there is no loss or gain for your business [5]. Every dollar of revenue above break-even is profit.
Hypothetical: If your monthly expenses are $3,000 and your average customer pays $100, you need 30 customers per month to break even. Customer 31 is your first profit. Source: Finance4Everyone calculation using [5] data.
Understanding this metric is crucial for determining minimum sales targets, pricing products smarter, and forecasting when your company will become profitable [5]. If you are planning a new venture, use our Budget Simulator to practice tracking these costs.
