Home ProjectCalc Do-It-Yourself Project Calculator

Calculator is great. Cheap and reliable. Hopefully homedepot will have available battery for it. I have bought this item last year but the battery expired recently and could not find any replacement. So I thought I’ll just buy a new one instead.

Regardless of how much planning I try to do for a project, especially decorating, I can pretty much guarantee that I will be going to the store more than once to either buy additional materials or to return materials because I calculated incorrectly. That is why I love this DIY calculator! Now I measure the area I want to work on and feed the measurements into the calculator and it does all the clever calculations and I can be sure that I am getting the right amount of supplies to complete the job. It can be used to calculate the correct amount of supplies for paint, wallpaper, tile, carpet and concrete. Paint will show in gallons, quarts or pints and the tile function changes the size of the tile, and therefore the quantity needed, each time the button is pressed. What’s more, the calculator will convert, for example, yards into feet or feet into metres. It has functionality to calculate square and cubic areas and material costs. The battery is claimed to last 575 hours – that’s a lot of projects – and has a built in hard cover to protect the screen and input buttons. The instruction book provides easy to follow step by step instructions and there are links to downloadable guides and a YouTube channel with helpful videos. A 12 month warranty is provided. At less than $15.00 this tool is terrific value and will undoubtedly save me more than that this year alone.

Good little calculator, mostly just another calculator with a few added functions, would be a lot better with a few more projects for wider use, but the ones on it word great, so would say for the average do it yourselfer would do ok makes a few things a little easier like number of bags of concrete needed or yards for larger projects, amount of paint is nice also. Said for Gardeners but nave not figured out what or how that would work, like for number of plants needed is the only thing I see but can do with any calculator. But is a good calculator just not much in the way of saving time on everyday shop or field use.

Used this for the first time and had an ease of a time. Plus I feel confident with my calculations. Measures a variety of material needs in Feet, inches yards and fractions. There are so many applications for this calculator. Comes with instruction in English and Spanish. Instructions are kept in the inside door for easy access. Plus there is info. on armor and useage. With a downloadable app.

I use this daily in our fabrication shop to verify vessel fabrication layouts.

It works as expected! A great tool!

I've had this calculator for about 10 years and it's my go to calculator for all my around the house improvement projects. It is easy to use and I really like the inch to foot quick conversion for lumber and plywood sizing and cutting.

Great calculator, can work with fractions, since I work with wood, is very helpful.
