Understanding Your Profit

Revenue vs. Profit

Revenue is what your business earns. Profit is what it keeps. A business generating $20,000 per month in revenue but spending $19,000 is not healthy — even though it sounds impressive.

Profit = Revenue − Total Expenses

What Is Profit Margin?

Profit margin is the percentage of revenue you keep as profit. A 30% margin means for every $100 you earn, $30 stays in the business. Margin is more important than raw profit when comparing performance over time.

Margin = (Profit ÷ Revenue) × 100

Monthly vs. Annual View

Monthly numbers can hide trends. One good month can look like success when the rest of the year tells a different story. Always look at your annualised profit to understand the real health of the business.

Annual Profit = Monthly Profit × 12

When to Be Concerned

A margin below 10% means costs are eating most of your revenue — one bad month can push you into a loss. Below 5%, the business is fragile and needs immediate attention to either reduce expenses or raise prices.

Risk Zone: Margin < 10%

Why business owners overestimate their profitability

Focusing on revenue, not profit. Revenue growth feels good but means nothing if costs are growing faster. A business that doubles revenue but triples expenses is moving backward.
Forgetting irregular expenses. Annual insurance premiums, equipment replacements, and tax bills don't appear every month — but they are real costs that belong in your profit picture.
Not separating personal and business finances. When business and personal spending mix, it's almost impossible to know what the business truly earns. Separate accounts are not optional.
Ignoring owner's salary as an expense. If you pay yourself from revenue without booking it as a cost, your profit is overstated. Your labor has a market value — it belongs in expenses.
Mistaking cash flow for profit. Having money in the account doesn't mean you're profitable. Outstanding invoices, prepaid revenue, and deferred costs all distort what you see in the bank.

Frequently Asked Questions

It depends heavily on the industry. Service businesses and consultancies often achieve 20–40%. Retail and restaurants typically run 3–9%. As a general rule, a net margin above 15% is considered healthy for most small businesses, above 30% is excellent, and below 5% is a warning sign that costs need attention.

Yes. If you pay yourself from business revenue, your salary should appear in payroll costs. If you don't account for owner compensation as an expense, your profit numbers are artificially inflated and don't reflect the true cost of running the business. This matters especially when comparing your business to industry benchmarks.

Gross profit subtracts only the direct cost of producing your goods or services (cost of goods sold) from revenue. Net profit subtracts all expenses — operating costs, payroll, marketing, and overhead. This calculator estimates net profit. For product businesses, your gross margin will always be higher than your net margin.

Start by reviewing your expense breakdown. Identify the largest cost categories and ask whether each is generating a return. Common culprits are payroll inefficiencies, underpriced services, excessive ad spend with low ROI, or fixed costs that haven't been renegotiated as the business grew. Increasing revenue without fixing cost structure just magnifies the problem.

Not automatically. The profit shown here is pre-tax profit. To estimate your after-tax position, include your estimated monthly tax payments or quarterly estimated taxes in the "Other Expenses" field. For accurate tax planning, work with a CPA or accountant — tax treatment varies significantly by business structure (LLC, S-Corp, sole proprietor, etc.).
