Complete solution for concrete calculations with multi-currency support
Select currency for each material cost
Always add 5-10% extra concrete to account for spillage, over-excavation, and other wastage during placement.
Pour concrete when temperatures are between 10°C and 27°C. Avoid pouring in freezing conditions or extreme heat.
Use the minimum amount of water required for workability. Excess water weakens the concrete and causes cracks.
A concrete calculator is an essential tool for construction professionals, DIY enthusiasts, and anyone working with concrete. It helps you accurately determine the amount of concrete needed for your project, calculates material requirements (cement, sand, aggregate), and estimates the total cost.
Concrete Calculator takes this further by providing:
Calculate volumes for slabs, footings, columns, walls, circular slabs, curbs & gutters, and stairs
Calculate costs in USD, EUR, GBP, JPY, CAD and more with real-time conversions
Interactive charts for material composition and cost distribution
Work with meters, centimeters, feet, inches, and yards seamlessly
Choose from 7 different concrete structures based on your project needs
Input measurements using your preferred units (meters, feet, inches, etc.)
Set concrete density, mix ratio, wastage percentage, and cement bag size
Get instant results including volume, materials, weight, and cost breakdown
Our calculations are based on industry-standard formulas and account for material density, mix ratios, and wastage. For most projects, accuracy is within 3-5% when inputs are correctly measured.
Concrete projects typically have 5-10% wastage due to spillage, over-excavation, uneven surfaces, and other factors. Adding this percentage ensures you don't run short during your project.
Yes! You can set different currencies for each material cost. The calculator automatically converts all costs to your display currency using current exchange rates.
The mix ratio depends on your project requirements:
For stairs, you need:
Our calculator will determine the number of steps and total volume.
