About Business Toolbox Pro

Business Toolbox Pro is a free collection of eleven calculators for small business owners, freelancers and shop managers: profit margin, markup, break-even, employee cost, hourly rate, invoice due dates, payment terms, inventory reordering, stock turnover, sales commission and discounts.

Why it exists

Most business maths is simple but easy to get wrong when you are busy. Each tool here asks only for the numbers you already have and shows the answer straight away, in English, Urdu or Spanish, with no sign-up.

Please note

Results are estimates based on standard formulas. They are not accounting, tax or legal advice, so check important figures with a qualified professional.
