Profitability Calculator

A profitability calculator compares your total revenue against your total costs — including cost of goods, operating expenses, marketing, payroll, software, and taxes — to show your net profit, profit margin, and break-even point. Enter your figures and click "Calculate profitability" to see instant, client-side results.

Net profit margin is calculated as (Total Revenue − Total Costs) ÷ Total Revenue × 100. It shows what percentage of your revenue remains as profit after every expense, including COGS, operating costs, marketing, payroll, software, and taxes, has been paid.

Break-even revenue is the amount of revenue needed to cover your fixed costs given your gross margin. It is calculated as Fixed Costs ÷ (Gross Margin ÷ 100). Knowing this number helps you understand exactly how much you need to sell before you start generating real profit.

Enable the SaaS metrics section and enter your marketing spend, new customers acquired, average revenue per user, and churn rate. CAC is marketing spend divided by new customers, and LTV is estimated as ARPU divided by your churn rate. A healthy LTV:CAC ratio is 3:1 or higher.

No. All calculations run entirely in your browser. Your figures are only saved to your own browser's local storage so you can return to your calculation later — nothing is ever sent to a server or shared with anyone.

Yes. The core revenue and cost fields work for any business model. The optional SaaS section adds MRR, ARR, ARPU, CAC, and LTV calculations specifically useful for subscription businesses, but you can leave it off for e-commerce, agencies, or freelance work.
