Concrete Calculator-Estimate Concrete Volume and Bags

How much Concrete do you need? Check With Our Concrete Quantity Calculators

The Concrete Calculator is used to estimate the volume and weight of concrete in different units to cover a given area. You can purchase more concrete than the estimated result to fulfill your required work. This reduces the chances of a concrete deficiency.

How Much Concrete Do You Need? Calculate the exact amount of concrete required for slabs, square footings, walls, holes, columns, round footings, circular slabs or tubes, curbs and gutter barriers, and stairs using our free concrete calculators at calculatorconcrete.net for fast and accurate estimates.

Concrete Calculators for Building Projects

If you are a professional contractor or a homeowner, then concrete work is challenging for you. If you do not know the proper quantity of concrete at the time, then your project is delayed, and the majority of the money will be lost.

You can rapidly and efficiently estimate material by using calculatorconcrete.net. We are providing five different kinds of concrete calculators that make project planning easier and more precise. Their details are as follows.

Calculator for Slabs, Square Footings, or Walls

By entering length, breadth, and thickness/height, you can compute concrete for walls, slabs, and square footings.
Many building projects are built on slabs, footings, and walls. From roads and patios to garden walls and tiny sheds, it begins. Inaccurate concrete calculations lead to unfinished work. For instant results, use our Slabs, Square footings, or walls calculator.


You can calculate how much concrete is required by using the Slabs, Square Footings, or Walls Calculator. The calculator determines the necessary volume and weight by entering the length, breadth, and thickness. This helps you order the correct quantity each time and is ideal for driveways, garage floors, patios, and garden walls.

Calculator for Round, Column, or Hole Footings

You can calculate the concrete required for round, column, or hole footings by entering the diameter, height, or depth. Piers, posts, and columns must safely support heavy loads. Stability and safety problems arise from inaccurate concrete estimation. For instant calculation, use our Column, Hole, or Round Footings calculator.


You just need to enter the diameter and depth of your hole or column base when using the Hole, Column, or Round Footings Calculator. The instrument is perfect for structural columns, deck supports, and fence posts since it determines the volume of concrete required. This guarantees stable, secure footings and helps prevent additional excursions to the store.

Calculator for Concrete Circular Slab or Tube

By entering the outer diameter, inner diameter, and length/height, you can compute the concrete for a circular slab or tube.
Round patios, water features, pillar shapes, and garden features frequently use circular slabs and tubes. It is difficult and causes errors to calculate concrete for curved shapes. Use our Circular Slab or Tube calculator for instant results.


You can use the Concrete Circular Slab or Tube Calculator if required to estimate the volume of concrete when you enter the radius and thickness. This shows that you have the proper quantity for custom or round-shaped items, saves time, and minimizes waste.

Calculator for Concrete Curb and Gutter Barriers

By entering the curb depth, gutter width, curb height, flag thickness, and length, you can compute the concrete for curb or gutter barriers.
For appropriate drainage and road construction, curbs and gutters are essential. It is challenging to estimate concrete for these long, narrow, or irregular shapes. Use the Curb and Gutter Concrete Calculator for results.


You can enter the height, breadth, and length of your curbs or gutters using the Concrete Curb and Gutter Barrier Calculator. Driveways, parking lots, and street-side installations are completed effectively without over-ordering thanks to their clear, specific needs.

Calculator for Stairs

You can calculate the concrete for stairs by entering the run, rise, width, and platform/depth. Use our Stairs Concrete Calculator for instant results.
It is difficult to estimate the correct amount because concrete stairs include several steps with treads and risers. Inaccurate calculations can result in uneven, dangerous steps or waste concrete.


By entering the number of steps, tread depth, and riser height, the Stairs Calculator determines the total amount of concrete required. It guarantees that your stairs are sturdy, secure, and aesthetically pleasing, making it ideal for porches, decks, and garden steps.

Common Measurement Conversion for Concrete Work

These are a few questions related to concrete measurement and conversion.

How many feet are in a yard?

1 yard is equal to 3 feet. So, 1 feet= .33333 yard.

Yard to feet = Number of yards x 3

Calculate feet using our Feet in a Yard Calculator.

How many inches are in a yard?

1 yard is equal to 36 inches. The following formula is used to calculate yards to inches.

Yard to inches: Number of yards x 36

Calculate inches using our inches in a yard calculator.

How many cubic feet are in a cubic yard?

1 cubic yard is equal to 27 cubic feet. The following formula is used to calculate cubic feet in yards.

Cubic yards to Cubic feet= Number of cubic yards x 27

Use our cubic feet in a cubic yard calculator to calculate cubic feet.

How to calculate square feet?

You can calculate rectangular shape square feet= Length x width.

Use our Square feet calculator to find square feet.

Concrete Calculator FAQS

Why should a concrete calculator be used?

If you are tired of manual calculations, then calculatorconcrete.net is an online tool that helps to estimate concrete requirements for various construction projects.

How many bags of concrete do I need?

The number of bags depends on your project size and the bag type. You can estimate manually: calculate the volume of your area, convert it to cubic yards, then multiply by the number of bags per yard. Always order a little extra to account for waste or uneven surfaces.

What types of projects can this calculator be used for?

The concrete calculator is used for slabs, footings, walls, columns, circular slabs, tubes, curbs and gutters, stairs, and other common residential or commercial concrete projects.

How accurate is this concrete calculator?

The calculator provides reliable estimates based on the information entered. You can provide site conditions or a small margin for waste to get better results.

Should I still consult a contractor or concrete supplier?

Yes, for large, structural, or decorative concrete projects, it’s a good idea to confirm final requirements with a contractor or ready-mix concrete supplier before ordering.

Can this concrete calculator be used on mobile devices?

Yes, the concrete calculator is mobile-friendly and also works smoothly on tablets and desktop devices.

What are Concrete Estimating Tips?

Order a little extra: After using our calculator, always include a small margin to avoid running short.
Add slight thickness: A little extra depth helps with grading and compaction.
Simplify shapes: You can break irregular areas into simple shapes for easier estimates.
Steps and stairs: You need to calculate horizontal and vertical surfaces separately.
Prepare the ground: You have to ensure that the ground is properly prepared and leveled before pouring concrete.
