Ready Mix Mortar Calculator

Need to build a wall and wondering how much mortar to buy? You’re not alone. Many people ask, “How much ready mix mortar do I need?” That’s why we made this tool — to save your time and guesswork.

What Is Ready Mix Mortar?

Ready mix mortar is a blend of cement and sand. You don’t need to measure or mix it by hand. It’s pre-packed, just add water, and you’re good to go.

Think of it like pancake mix. You open the bag, mix in water, and start cooking. No fuss. No mess.

Why Use a Mortar Calculator?

Mixing too little mortar is a headache. Mixing too much? Waste of money. This tool helps you avoid both.

Here’s what it does:

• Calculates how much mortar you need
• Tells you how many cement bags to buy
• Works for bricks or blocks
• Adds extra for waste (because mistakes happen!)

How to Use the Calculator

Using it is easier than tying your shoelaces.

Just fill in:

• Wall length, height, and thickness
• Type of unit: brick, block, or custom
• Mortar mix ratio (like 1:6 for cement to sand)
• Cement bag size (25kg or 50kg)
• Wastage (we suggest 10%)

Click Calculate, and boom — you get:

• Wet mortar volume
• Dry mortar volume
• Cement and sand needed
• Bags of cement required

How the Math Works (No Stress)

We use a clear and tested formula behind the scenes. Here's the simple version:

Step 1: Find the Wall Volume

Length × Height × Thickness

Step 2: Subtract the Bricks or Blocks

Wall volume − volume of bricks = wet mortar

Step 3: Convert to Dry Mortar

Wet mortar × 1.33 = dry mortar (for shrinkage)

Step 4: Break It Down by Mix Ratio

Let’s say your mix is 1:6. That’s 1 part cement and 6 parts sand.

So:

• Cement = dry mortar ÷ 7
• Sand = dry mortar × (6 ÷ 7)

Step 5: Add Wastage

Add 10% to both cement and sand.

Step 6: Convert Cement Volume to Bags

Each bag (25kg or 50kg) covers a certain volume based on cement’s density.

Real-Life Example

Let’s say your wall is 10 meters long, 3 meters tall, and 0.23 meters thick. You’re using bricks, and the mix is 1:6.

Our calculator tells you:

• How much cement to buy
• How much sand to get
• How many bags you'll carry back from the store

Now that’s peace of mind.
