Business Calculators

Two of the most costly confusions in small business are margin vs markup and revenue vs profit. This category is being built to make those distinctions impossible to miss: the margin and markup calculators will show both numbers side by side (a 50% markup is only a 33% margin), ROI will annualize returns so different investments compare fairly, and break-even will translate fixed and variable costs into the units and revenue you need before profit starts.

Each tool is aimed at real pricing and planning decisions — setting a price, evaluating a purchase, judging whether a product line can work. Export the numbers, share the link with a partner, and nothing you enter ever leaves your browser.
