Fair Slice: a cake pricing calculator for home bakers
Fair Slice is a pricing tool for home bakers. Type what you paid for your ingredients and how long a bake takes. It shows the least you should charge so that every ingredient, box and hour is paid for. $14 once, no subscription.
Why buy it
Price every bake and pay yourself for every hour.
- One payment, yours to keep. No subscription and no account.
- Works offline: one file that opens in your web browser, with no internet needed.
- Shows the least you should charge, with every ingredient, box and hour paid for, and the price per serving.
- See what the price you charge today really pays you per hour, and print a cost sheet for any bake.
- Cup, spoon, pound and gallon conversions use the U.S. National Institute of Standards and Technology's published factors.
- Your numbers stay in your browser, on your computer. Nothing you type is sent anywhere.
- Instant download: the tool, a 5-page Start Here guide, a README and the license.
Good to know: Fair Slice runs on a computer, in your web browser.
Who this is for
- Home bakers who price cakes and other bakes and want to see the least to charge, so every ingredient, box and hour is paid for.
- Bakers who price more than one order and are tired of typing their prices again each time.
Who this is not for
- Anyone who needs it on a phone or tablet. It opens on a computer or laptop.
- Someone who prices a cake now and then. The free calculator is enough.
What it does
- Turns the way you bake into what you paid: buy flour by the pound, bake by the cup. Cup and spoon weights for 22 common ingredients are filled in.
- Keeps your pantry, recipes and bakes, so pricing the next order takes a minute.
- Adds your time at the hourly rate you choose, plus running costs, card fees and profit.
- Shows the price as a cake slice. Each layer is one part of the price.
- Type what you charge now and see what it really pays you per hour.
- Prints a cost sheet for any bake.
- US, metric or Australian cups and spoons. Any money symbol.
How it works
Fair Slice is a single file that opens in your web browser. No account, no subscription, no internet needed. Your numbers stay in your browser on your computer, and you can save a backup file any time.
What you get
Instant download of one zip file: Fair-Slice.html (the tool), a 5-page Start Here guide (PDF), a README and the license.
Works on
A computer or laptop with a web browser (Windows, Mac or Chromebook).
Not for phones or tablets. The screen fits a phone, but a phone opens a downloaded file in its own viewer, and on an iPhone the Files app preview does not run it. If you buy on your phone, open your download link on a computer.
About the example
Fair Slice opens with a worked example: a pound cake priced with US average ingredient prices for August 2026 from the U.S. Bureau of Labor Statistics, and the US median pay for bakers ($17.86 an hour, May 2025). Replace them with your own numbers. This is a digital download. Nothing will be shipped.
License
For use in your own baking business. Please do not share or resell the file.
