Turn your revenue and expenses into gross, operating and net profit — with clear margins and a visual breakdown. Switch between monthly, quarterly and annual views and your preferred currency.

Net profit (monthly)

Enter your revenue and at least one expense to see profit.

What is a business profit calculator?

A business profit calculator takes your revenue and a list of expenses and works out how much profit your business keeps at each level: gross, operating and net. It also calculates the matching margins, so you can see not just how much you make but how efficiently you make it.

How does it work?

Enter your revenue and costs for a period — monthly, quarterly or annual. The calculator separates your cost of goods sold from your operating expenses and taxes, then computes each profit line and margin and charts where your money goes.

How is the result calculated?

Gross profit = Revenue − Cost of goods sold
Operating profit = Gross profit − Operating expenses
Net profit = Operating profit − Taxes
Margin = Profit ÷ Revenue × 100

Operating expenses include payroll, rent, marketing, software, insurance, utilities, professional services, shipping and any other overheads you add.

Example

A business with $100,000 revenue, $40,000 COGS and $34,000 of operating expenses has a $60,000 gross profit (60% margin) and a $26,000 operating profit (26% margin). After $5,000 of taxes, net profit is $21,000 — a 21% net margin. The stacked breakdown shows COGS as the largest cost, helping you decide whether to renegotiate supplier pricing or raise prices.

Who should use it?

Small business owners tracking profitability month to month.
Founders building a simple budget or forecast.
Freelancers and consultants checking their take-home profit.

Tips for improving profit

To lift net profit, focus on the biggest lines first. Raising prices even slightly flows almost entirely to the bottom line. Cutting low-return marketing, consolidating software subscriptions and reducing COGS through better sourcing all widen your margins. Once you know your break-even point — see our break-even calculator — you can set volume and pricing targets with confidence.

Limitations

This calculator uses the figures you enter and does not account for non-cash items, one-off events, accruals or the timing of payments. It is a management tool for understanding profitability, not a substitute for formal accounting or tax advice.

Frequently asked questions

What is the difference between gross, operating and net profit?

Gross profit is revenue minus the cost of goods sold. Operating profit subtracts your running expenses (payroll, rent, marketing and so on) from gross profit. Net profit then subtracts taxes, giving the money the business actually keeps.

How do I calculate profit margin?

Profit margin is profit divided by revenue, expressed as a percentage. For example, a net profit of $20,000 on $100,000 of revenue is a 20% net margin. The calculator shows gross, operating and net margins automatically.

Should I enter monthly or annual figures?

Either works. Choose monthly, quarterly or annual at the top and enter figures for that period. The results are shown for the same period, and an annualised net profit is included so you can see the yearly picture.

Why is my net profit negative?

A negative net profit means your total costs — cost of goods sold, operating expenses and taxes — exceed your revenue for the period. The breakdown table shows exactly where the money is going so you can find what to cut or where to grow revenue.
