ROI (Return Of Investment) Calculator For Bricks Manufacturing

In the competitive world of construction and manufacturing, understanding the return on investment (ROI) is essential. For businesses involved in brick or block manufacturing, having a clear and well-structured method to calculate costs and profitability can mean the difference between a thriving venture and an unsustainable one.

This blog will walk you through a detailed ROI calculation process based on an intuitive software tool designed to estimate costs, profits, and comparisons across various production models.

Step 1: Choose the Type of Product

Begin your ROI calculation process by identifying the specific type of block you intend to produce. The interface will display a variety of block options, each designed to serve different construction needs. These typically include:

Concrete Bricks
Hollow Blocks
Paver Blocks
Fly Ash Bricks

Carefully review the available choices displayed in the selection panel. Once you’ve determined the block type that aligns with your business or project goals, click on that specific option to proceed further.

Example: If you’re planning to manufacture Fly Ash Bricks, simply click on the “Fly Ash Brick” option from the selection list to move to the next step in the setup process.

Step 2: Choose the Size of Product

After choosing the type of block you wish to manufacture (e.g., Fly Ash Bricks), the next step involves selecting the most suitable size for your production requirements. This is an important decision, as the size directly impacts material usage, weight, and production cost.

Key Points for Selection:

Select Available Sizes
Make Your Selection
Proceed to the Next Step

Step 3 - Define Product Specifications

This step involves customizing the core specifications of your chosen brick product to ensure accuracy in cost and material estimates. Here’s a breakdown of what you need to configure:

Select the Brick Strength (MPa)

Choose the desired compressive strength rating for your bricks.
Common options include M7, M8, etc., which reflect how much pressure the brick can withstand.
The strength grade directly affects the brick’s durability and is an important factor in construction quality.

Density (Auto-Populated Based on Strength)

Once you select a strength value, the system will automatically update the corresponding density.
Example:
- For M7, the density will be 2100 kg/m³.
- For M8, it increases to 2150 kg/m³.
This auto-calculation ensures that the material properties are consistent with real-world standards.

Set the Height of the Brick (Customizable)

You can manually input the height of the brick to suit your project requirements.
Example: You may choose 75 mm, 90 mm, or any other preferred value depending on the design specification.

Input Quantity

Enter the total number of bricks you plan to manufacture.
This can range from a small batch (e.g., 1, 5) to a large-scale production run (1000, 5000, or more).
Accurate input here ensures proper cost estimation.

Confirm Brick Dimensions

Double-check that the system displays the correct dimensions:
- Length (e.g., 230 mm)
- Width (e.g., 110 mm)
- Height (as entered by you)
This step ensures consistency in production and packing calculations.

Review Volume & Weight (Automatically Calculated

Based on the entered specifications, the tool will compute:
- Product Volume: e.g., 0.001897 m³
- Product Weight: e.g., 3.984750 kg
These values are critical for calculating raw material requirements and transportation planning.

Step 4: Select Raw Materials

After you have finalized the product specifications—such as size, strength, and quantity—the system will automatically generate a list of raw materials based on the type of brick you’ve selected. This helps streamline the process by providing a predefined material mix suitable for your chosen product.

Selection Based on Brick Type

The tool intelligently selects the appropriate raw materials typically used for your brick type.
For example, in the case of Fly Ash Bricks, the common materials include:
- Cement (OPC 53 Grade)
- Fly Ash
- Stone Dust
- 6 mm Coarse Aggregate
While the default materials are recommended, you have the flexibility to manually adjust or replace any component in the list.

Proceed to Cost Estimation

Once you’re satisfied with the material selection, click on the “Next” button to continue to the Raw Material Cost & Recipe section, where you’ll input prices and finalize the mix ratio.

Step 5: Raw Material Cost & Recipe (Part - 1)

As you move forward to the cost estimation phase, the currency you selected earlier such as INR (Indian Rupee) will automatically be applied to all pricing fields in the upcoming steps.
If you need to work in a different currencywhether due to international operations or regional pricing you can manually change the currency before proceeding.

Step 5: Raw Material Cost & Recipe (Part - 2)

Once you choose the currency, the system will automatically navigate to the Base Mix Raw Material Cost & Recipe section.

Default Ratios & Custom Options

Material ratios (Cement, Fly Ash, Stone Dust, Coarse Aggregate, etc.) are pre-set based on the selected brick type.
You can adjust these ratios manually if needed.

Choose Pricing Unit

Raw materials can be priced in various units depending on availability:

Kg – Standard unit for most materials
Ton – Ideal for bulk quantities
Bag (50 Kg) – Common for cement and similar products

Step 5: Raw Material Cost & Recipe (Part - 3)

Example Calculation for Cement Cost:

If Cement is selected in Kg, enter ₹7 per kg
If selected in Ton, enter ₹7000 per ton
If selected in Bag (50 kg), enter ₹350 per bag

You can choose the unit that best matches your purchase format.

Coarse Aggregate Pricing Options:

For Coarse Aggregates (such as 6mm, 12mm, etc.), you can select from four unit options depending on availability and measurement preference:

Kg – Ideal for small-scale purchases.
Ton – Best suited for bulk buying (1 Ton = 1000 Kg).
m³ (Cubic Meter) – Suitable for volume-based pricing.
ft³ (Cubic Feet) – Another option for volume-based measurements.

Step 5: Raw Material Cost & Recipe (Part - 5)

Coarse Aggregate Pricing Options:

For Coarse Aggregates (such as 6mm, 12mm, etc.), you can select from four unit options depending on availability and measurement preference:

Kg – Ideal for small-scale purchases.
Ton – Best suited for bulk buying (1 Ton = 1000 Kg).
m³ (Cubic Meter) – Suitable for volume-based pricing.
ft³ (Cubic Feet) – Another option for volume-based measurements.

Note: The total percentage must always equal 100%.

If the sum is more or less than 100%, the system will prompt you to adjust the values accordingly.

Step 5: Raw Material Cost & Recipe (Part - 6)

Entering Costs

Enter the cost per selected unit for each raw material.
Make sure all values are accurate to ensure correct cost calculations.

Proceeding to the Next Step

After entering all required values, click “Next” to continue to the Operation Cost section.

Step 5: Raw Material Cost & Recipe (Final Cost Break Down)

The total cost is calculated per brick based on the weight distribution of each material.

Final Cost Breakdown:

Total Cost Base Mix → The sum of all material costs.
Total Raw Material Cost (Qt. 1) → The total cost for 1 brick.
Total Raw Material Cost Per Piece → The final cost per brick.
