FreeConcreteCalc
Calculate Concrete for Any Project — Bags, Yards & Cost
Free concrete calculator for slabs, footings, post holes, walls, columns & stairs. Calculate cubic yards, 60lb & 80lb bag counts, and project cost — works like Quikrete and Sakrete calculators but with more features.
I kept running into the same problem every time I had a concrete project - go to Google, click a calculator site, get hit with 20 ads, scroll past SEO filler, and finally get a number that doesn't even include waste factor. So I end up at Home Depot with not enough bags and have to make a second trip mid-pour.
I built FreeConcreteCalc to fix that. You punch in your dimensions and instantly get exact bag counts (60lb and 80lb), cubic yards for ready-mix orders, and cost estimates - all with a 10% waste factor built in so you never run short.
It supports 8 project types (slabs, footings, post holes, walls, columns, stairs, curbs) and lets you combine multiple zones in one calculation. There's also PDF export, a share link, dark mode, and it works great on mobile at the job site.
No signup, no paywall, no ads blocking your results. Just the numbers you need before you drive to the hardware store.
Would love to hear from anyone who's poured concrete - what would make this more useful for your next project?
How accurate is the cost estimator when you account for waste or overage, and does it factor in regional price differences for materials?
this is exactly what i needed for a backyard patio pour last weekend. loved that it broke down bag counts by both 60 and 80 pound sizes, plus gave a cost estimate that actually matched the receipt.
