This started after I bought way too much pea gravel for a patio project. The calculator I used online didn't account for depth properly, and I ended up with enough leftover gravel to fill a swimming pool. That was around $400 wasted.
Then there was the insulation project where I underestimated by 30%. Had to make three separate trips to Lowe's because I kept doing the math wrong on R-values and square footage.
So I started building these calculators for myself. They actually worked, so I put them online. Turns out a lot of people have the same problems with material estimates. Meet the team building these tools.
"saved me like 3 trips to home depot for my mulch project, thanks"
"Actually got the spray foam right on the first try. Your calculator is way better than the one on the manufacturer's site."
"I'm a contractor and I use these lol"
Made by people who've screwed up enough projects to know what matters
We test these against actual projects. Waste factors are based on what really happens, not theoretical perfect conditions.
We've done most of these projects ourselves. Some went well. Some didn't. The calculators reflect what we learned.
No login screens. No "create an account to see results." No freemium nonsense. Just calculators that work.
When people email saying "your mulch calculator was off," we fix it. Sometimes they're right.
Bag sizes are different depending where you live. We're still working on getting all the variations right.
We add calculators based on what people ask for. River rock was requested like 50 times, so we built it.
Pick a calculator and get your material estimates. No signup, no payment info, just the numbers you need.
