📊About Business Calculators
Whether you're a freelancer setting your hourly rate, a small business owner calculating the break-even units for a new product, an e-commerce seller figuring out the maximum discount you can offer without going below your target margin, or a startup founder modeling customer lifetime value — these business calculators replace hours of spreadsheet work with instant answers.
Start with the Profit Margin Calculator if you sell any product or service — it shows the difference between margin and markup (a distinction that trips up even experienced business owners) and lets you reverse-calculate the selling price needed to hit a target margin. The Break-Even Calculator shows exactly how many units you must sell before profitability — with a visual chart mapping revenue vs cost curves.
What sets these tools apart: the Discount Calculator correctly handles stacked discounts (30% off + 20% off ≠ 50% off) and shows how tax interacts with discounted prices. The Customer Lifetime Value calculator uses a cohort-based model rather than a simple average, giving a more realistic CLV for businesses with churn. Every result includes a plain-language explanation of what the number means for your specific business context.
