Business calculators
Quick answers to everyday business math, worked out as you type. Each one shows how it got there, and links to a hands-on lesson on the idea behind it.
Food cost calculator
Add up a dish's ingredients, type its menu price, and see what share of the price the food takes. Or work back from a target to a price.
Break-even calculator
Type your fixed costs, your price and what each sale costs you, and see how many sales a month and a day you need just to stay even.
Markup vs. margin calculator
See the markup and the margin from a cost and a price, or turn a markup into a margin and back.
The numbers you type stay on the page and aren't sent anywhere. For learning, not financial advice.
