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.

Costs and prices

What one thing costs you, what to charge for it, and what's left.

  • 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.

  • 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.

  • Price for a target margin calculator

    Type what one costs you and the margin you want, with any card fees or discounts, and see the price, the markup and the profit on each sale.

  • Labor cost calculator

    See what a worker really costs an hour and a shift, with payroll taxes, state costs and benefits, and your labor cost as a share of a week's sales.

Planning and cash

What it takes to open, how many sales cover the bills, how long the cash lasts, and what a customer costs.

  • Startup cost calculator

    List what you'll pay once to open, set aside months of running costs and a cushion, and see the total it takes to start.

  • 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.

  • Cash runway calculator

    Type the cash in the bank, your costs and the money coming in each month, and see how many months the cash lasts, with or without sales growing.

  • Customer cost and payback calculator

    See what it costs to win a customer, how many months of their buying pay it back, and what they're worth if they stay.

The numbers you type stay on the page and aren't sent anywhere. For learning, not financial advice.
