Electricity Cost Calculator

Formula for Electricity Cost Calculator

Formula:

Electricity Cost = Power Consumption (in kWh) × Electricity Rate (per kWh)

Where:

• Power Consumption (kWh) = Device Wattage × Usage Hours ÷ 1000
• Electricity Cost (Tk) = Power Consumption × Rate per kWh

Why Textile Factories Must Track Electricity Costs

Textile factories use many machines that need electricity. Each machine adds to the total monthly cost. If we know how much electricity a machine uses, we can save money. Electricity cost calculators help factory managers track these costs in real time.

How the Electricity Cost Calculator Works

Use Basic Inputs to Estimate Cost

This calculator uses three simple inputs:

• Device wattage (W)
• Daily usage time (hours)
• Rate per kilowatt-hour (Tk/kWh)

Step-by-Step Calculation

Step 1 – Convert Watt to Kilowatt

Divide the device wattage by 1000 to get kilowatts (kW).

Step 2 – Calculate Daily Power Use

Multiply the kilowatts by the usage hours per day to get energy in kWh.

Step 3 – Multiply by Rate

Multiply the energy (kWh) by the electricity rate to get the total daily cost in Taka.

This method gives quick results and helps you plan energy usage smartly.

Use in Textile Manufacturing Units

Machines That Need Cost Monitoring

In my work as a textile engineer, I deal with many power-hungry machines. Some common ones include:

• Spinning machines
• Air compressors
• Dyeing machines
• Printing units
• Air conditioners
• Lighting systems

Each of these can run for long hours. Some work for 20+ hours a day.

Example: Power Cost of a Dyeing Machine

Let’s say your dyeing machine uses 3000 watts and runs for 10 hours. The electricity rate is 7.5 Tk per kWh.

• 3000 W = 3 kW
• Daily use = 3 × 10 = 30 kWh
• Daily cost = 30 × 7.5 = 225 Tk

With this simple example, you see how fast the cost adds up.

Benefits for Factory Management

Improve Budget Planning

The electricity cost calculator helps you set accurate budgets. You can predict monthly energy bills more easily.

Reduce Wastage

When you know how much each machine costs, you can avoid running unused machines. This helps save power and cut down waste.

Improve Machine Scheduling

You can plan shift timing for high-power machines. Use costly machines during off-peak hours when rates are low.

Support Costing Team

Your costing and finance teams can use this data to calculate product cost more precisely. Energy use per product is important in pricing.

Who Should Use This Calculator?

This calculator is useful for:

• Textile factory managers
• Energy auditors
• Costing officers
• Sustainability teams
• Students of textile engineering

Anyone working with industrial power use can benefit from it.

How to Use the Calculator Online

Input the Following:

• Device wattage (default is 100 W)
• Hours per day (default is 5 hours)
• Rate per unit (default is 7.5 Tk/kWh)

Get Instant Output

Once you click “Calculate,” the daily electricity cost appears. You can reset the form using the “Refresh” button.

The default values help beginners check results without confusion.

Why Simplicity Matters in Power Calculation

As a textile engineer, I often see teams struggle with long Excel sheets. This tool gives quick answers without formulas. It saves time and reduces errors. You don’t need training to use it. The tool works well for both experts and beginners.

Final Words

Energy costs affect product pricing in textile factories. By using an electricity cost calculator, you can manage your power use better. You can reduce waste, improve planning, and help your team make smart decisions. This tool is small, but the benefit is big.
