Business Calculators
Every business calculator on the site, in one place - pricing, profitability, payroll, and growth tools, grouped by what you're actually deciding.
Each tool shows its formula and a fully worked example directly on the page - and several go further, flagging the specific mix-up (margin vs. markup, ROI vs. CAGR, stacked discounts) that trips people up most often in that calculation. Every calculation runs in your browser and nothing you enter is saved. Jump to a section, or scroll through all 16.

Frequently asked questions
Are these business calculators free to use?
Yes - all 16 tools on this page are free, with no account or sign-up required.
Are these suitable for an actual business decision, or just estimates?
These tools use standard, widely accepted business formulas and are well suited for everyday pricing, planning, and analysis. For anything with legal or tax consequences - payroll tax filings, a formal business valuation for a sale, or a major financing decision - confirm the details with an accountant, tax professional, or business advisor.
Why do several tools specifically call out common mix-ups, like margin vs. markup?
Because these are genuinely easy mistakes with real financial consequences - pricing a product using markup math when you actually meant margin, for instance, quietly erodes profit on every single sale. Calling it out directly, not just showing the formula, is meant to help it actually stick.
Is any of the information I enter saved?
No. Every calculation runs directly in your browser - nothing you type is sent to a server or stored anywhere.
