About CrunchSheet

Hey, I'm Sami. I built CrunchSheet because I kept Googling the same calculations and landing on ad-heavy pages that made simple maths harder than it needed to be. So I made something better.

CrunchSheet is a growing collection of online calculators for everyday tasks. Need to work out a concrete mix? Figure out how much paint to buy? Check VAT on an invoice? Just pick a calculator, plug in your numbers, and get the answer straight away.

Everything runs in your browser. Nothing gets sent to a server, there's no account to create, and results update as you type. CrunchSheet also works offline as a progressive web app, so you can use it anywhere, even without a connection.

The formulas behind each calculator are based on established references and are regularly checked for accuracy. If something looks off or you've got an idea for a calculator you'd like to see, drop me a message.
