Frequently asked questions

Common questions about business calculators and how to use them.

Who are these business calculators for?

Small business owners, founders, ecommerce sellers, and operators who need a fast, transparent estimate. They cover pricing and margin, break-even, advertising returns, customer economics, and inventory timing — each with the full cost stack shown.

What is the difference between margin and markup?

Markup is profit as a percentage of cost; margin is profit as a percentage of the selling price. A 50% markup is only a 33% margin. The markup and profit-margin calculators let you move between the two without confusion.

Does a high ROAS mean my ads are profitable?

Not by itself. A ROAS that looks high can still lose money once product cost, fees, shipping, and returns are counted. Use the break-even ROAS calculator to find the return your margins actually require, then compare your campaign against it.

Are these accounting or tax advice?

No. They are educational tools for planning and analysis based on the figures you enter. They are not accounting, tax, or financial advice — verify important numbers with your own records and a qualified professional.
