COMMON QUESTIONS
A few things worth knowing.
Clear answers about the calculators, your data, and how to use each result.
Are the SmallBiz Lab calculators free?
Yes. All calculators are free to use, and you do not need a credit card to calculate a result.
Does SmallBiz Lab save the numbers I enter?
No. Calculator inputs and results stay in your browser and are not sent to SmallBiz Lab or stored in a database.
What numbers should I use in a calculator?
Use recent, business-specific figures whenever possible. The example values show how each calculator works, but your own bookkeeping records will produce the most useful estimate.
What is the difference between margin and markup?
Margin compares profit with sales revenue. Markup compares profit with cost. Because they use different starting points, the same percentage does not produce the same price.
Are these results accounting, tax, or legal advice?
No. SmallBiz Lab provides planning estimates and educational information. Confirm important financial, tax, and legal decisions with a qualified professional.
