Concrete Bag & Mix Calculator

Concrete Mix Ratio Calc helps contractors and owner-builders turn a concrete mix ratio into a practical pour plan: cement, sand, aggregate, concrete bags, waste, and estimated cost in one offline worksheet. Use it to: - calculate cement, sand, and aggregate amounts from standard 1:2:4, lean 1:3:6, rich 1:1.5:3, or custom ratios - size slab, footing, and post-hole jobs from real dimensions - add waste percent so the buy list does not undercount bags - enter the bag yield printed by your supplier - add optional bag price to estimate material cost - see exact bags, rounded bags to buy, and the mix-ratio breakdown together - share a supplier-ready summary by text Why people buy Concrete Mix Ratio Calc: - faster than rebuilding concrete mix ratio formulas in a browser - useful when signal is weak at the yard or jobsite - one avoided second store trip can repay the app - paid once, with no ads, account, tracking, or cloud workflow Concrete Mix Ratio Calc works best for: - concrete mix ratio checks before a small pour - patio pads, small slabs, and repair pours - fence and deck post holes - narrow footing runs and form checks - small crews and owner-builders who want a focused utility, not a full construction suite This app is a planning aid. It does not provide structural engineering, code compliance, strength certification, or supplier guarantees. Always verify local material specs before ordering or pouring.
