Mix – Concrete Calculator Live

Calculate concrete mix ratios, bag counts, material quantities, and total volume for six shapes in one app. Mix is a concrete calculator for contractors and DIYers who need fast, accurate estimates for slabs, steps, footings, columns, round slabs, and curbs and gutters. WHAT IT CALCULATES Mix handles six shape types on one screen: rectangular slab, round slab, footing, column, steps, and curbs and gutters. Enter dimensions and get results instantly for driveways, patios, footings, fence post bases, staircases, and curb and gutter runs. Steps are a real gap in many free concrete calculator apps. Most stop at slab and footing math. Mix includes a dedicated steps calculator so you can estimate stairs without forcing the job into a slab formula. Curbs and gutters are another use case many simple apps skip. CONCRETE MIX CALCULATOR Mix is more than a concrete volume calculator. Choose a mix grade from M10 to M50, or enter a custom mix ratio for your job. For each result you get a full material breakdown: cement, sand, aggregate, and water for the exact volume you plan to pour. Bag count is shown with the material breakdown, so you can estimate concrete bags and bulk materials in one result. Enter an optional price and Mix adds an estimated cost. If you need a cement calculator, concrete mix calculator, and concrete volume calculator, Mix does all three in one screen. POUR LIST Most jobs are not one pour. Use the pour list to add slabs, footings, steps, curbs, gutters, and other pours to the same project. Mix totals the volumes so you can estimate the full job before ordering ready-mix or bags. HOW TO USE IT Select a shape and enter the measurements. A labeled diagram shows which dimension goes where, so there is no guesswork. Choose a mix grade or enter a custom ratio. Set your waste factor, add an optional price, and tap Calculate. Mix returns volume, bags needed for standard bag sizes, and full material quantities. Save the result to your pour list or history, then keep adding shapes until you have the total concrete volume for the job. UNITS Mix works in imperial and metric. Imperial output shows cubic yards and cubic feet. Metric output shows cubic meters and kg bag sizes. If you need a concrete calculator in feet or a cement calculator in cubic meters, you can switch units with one tap. WHY MIX Many concrete apps stop at volume and bag count. Mix adds mix ratios, materials, labeled diagrams, steps, curbs and gutters, waste factor, cost estimate, and pour list totals in one app. No subscription. No account. No overbuilt interface. Mix uses a clean Material 3 layout that is easy to use on a job site. Large fields, clear diagrams, and fast results make it practical for contractors and simple enough for DIY projects. USE CASES Use Mix for driveway slabs, patio pads, sidewalks, round pads, deck footings, fence post holes, foundation footings, retaining wall sections, concrete stairs, and curb and gutter runs. It works as a concrete slab calculator, a footing concrete calculator, a steps calculator, and a curb and gutter concrete calculator in one app. COMMON QUESTIONS How many bags of concrete do I need for a 10x10 slab? A 4-inch slab is about 1.23 cubic yards. At a standard M20 mix, that is roughly 37 bags of 80 lb concrete. Enter 10 ft x 10 ft x 4 in and Mix calculates it instantly. How do I calculate concrete for steps? Select Steps, enter the number of steps, rise, run, and width, and Mix calculates total volume and bag count for the staircase. How do I estimate curbs and gutters? Select the curbs and gutters shape, enter the run dimensions, and Mix calculates concrete volume, bag count, and material quantities. How do I total multiple pours? Save each result to the pour list and Mix adds the volumes so you can estimate the whole project before you order concrete.
