## What is Concrete Calc?

Quote any concrete job before the customer gets back in the truck. Concrete Calc estimates cubic yards, bag count, and total material cost for slab, footing, and circular column pours in under 30 seconds — no signup, no ads, no scrolling through 15 calculators you'll never use.

WHAT IT DOES
• Three pour shapes: rectangular slab, footing, and circular column
• Cubic yards + bag count for 40lb, 60lb, and 80lb mixes
• Cost estimate at your entered $/yd³ — call the ready-mix supplier or quote the customer
• Imperial or metric input, swap anytime

WHO IT'S FOR
Working concrete contractors — owner-operators, foremen, and small crews — who need a fast number on-site to call the ready-mix supplier or quote the customer. If you're pricing a residential driveway, garage slab, or footing job, this is built for you.

WHY THIS APP
Most concrete calculators are either bloated with 15 features you don't need, or so basic they only give you a yardage number with no way to turn it into a quote. Concrete Calc covers the full contractor workflow: dimensions in, quote out. No clutter. No subscriptions.

ON THE JOB
Pick the shape — slab, footing, or column. Punch the dimensions. Get cubic yards rounded for ready-mix ordering. Bag count for 40lb, 60lb, and 80lb mixes. Total cost ready to text the customer or call the ready-mix supplier. Switch imperial or metric mid-job and the form resets cleanly so a '10' never gets confused between feet and meters.

COMMON QUESTIONS
Q: Density? Standard concrete weight, 145 lb/ft³ — what most ready-mix suppliers use as baseline.
Q: Bag yields? 40lb bag = 0.30 cu ft, 60lb = 0.45 cu ft, 80lb = 0.60 cu ft. Industry-standard pour volumes.
Q: Block, wall, rebar? Not in v1. Slab, footing, and circular column only.

PRICING
Free to download. Calculate cubic yards and bag count free, forever. One-time in-app purchase unlocks cost estimation. No subscriptions, no recurring charges.

PRIVACY
No accounts. No tracking. No data leaves your phone.

DISCLAIMER
Estimates only — verify with your supplier and project specs.
