# DIY: concrete calculator

Updated July 20, 2017

A do-it-yourself project can always be rewarding when you get the job done and the results are good. And with all the tools and supplies you might need, a DIY project can make a dent in your wallet. If you don't do the math and know how much concrete you will need to finish a project, concrete gets expensive fast. But it doesn't have to. With careful calculations of the size of the project, you can figure out fairly easy exactly how much concrete you need so you don't break the bank.

## Measurements and calculations

Measure out the area you wish to place the concrete so that you can come up with a measurement in cubic yards and calculate how much concrete you will need to fill that space with. Take a measurement of the width, length and thickness of the slab so you have a volume measurement. If you're not an algebra wiz and can't figure this out, don't worry. You can take your measurements and enter them into one of the links for the concrete calculators provided below, and the calculator can tell you how many cubic yards your project is, as well as how many bags of concrete you will need, depending on the weight of the bag.
