Annual Electricity Cost Calculator in Factory
Formula for “Annual Electricity Cost Calculator in Factory”
To calculate the annual electricity cost in a factory, we use the following formula:
Annual Electricity Cost (BDT) = (Power Consumption per Hour in kW) × (Operating Hours per Day) × (Number of Operating Days per Year) × (Electricity Rate per kWh)
Where:
- Power Consumption per Hour = Machine Power (in kW)
- Operating Hours per Day = How many hours the machine runs per day
- Operating Days per Year = Usually 300–365 (depending on shifts & holidays)
- Electricity Rate per kWh = e.g., 11 BDT/kWh (default based on average industrial rate in Bangladesh)

Why Electricity Cost Matters in Factory Operations
Electricity runs every machine in a textile factory. Machines need power to weave, knit, dye, and dry fabrics. Every hour of machine operation adds cost. So, factory managers need to check the yearly electricity cost. This helps in reducing waste and saving money. Using a simple calculator gives a quick and clear estimate of this cost.
Key Inputs for the Calculator
Machine Power in kW
Every machine uses a certain amount of power. This value is given in kilowatts (kW). In most spinning or weaving factories, machines use between 2 kW and 100 kW.
Operating Hours per Day
Factories do not run 24 hours every day. Most textile units run in shifts. A factory may run 10 hours per day or even 20 hours in two shifts. The calculator needs this daily hour value.
Operating Days per Year
Factories do not run every day. Holidays, maintenance, and other issues reduce the number of days. A factory usually operates around 330 days in a year.
Electricity Rate per kWh
The cost of 1 kilowatt-hour (kWh) of electricity depends on your location. In Bangladesh, the average industrial rate is around 11 BDT per kWh.
Sample Calculation for a Textile Factory
Let us assume:
- Machine Power = 50 kW
- Operating Hours per Day = 10
- Operating Days = 330
- Rate = 11 BDT per kWh
Now apply the formula:
Annual Cost = 50 × 10 × 330 × 11 = 1,815,000 BDT
This factory will spend 18.15 lakh taka per year on electricity for this machine. If the factory has 10 similar machines, the cost becomes 1.81 crore BDT.
Benefits of Using the Calculator
Fast Decision Making
Managers do not need to wait. They just input values and get the result. This helps in fast planning for production and budgeting.
Better Energy Management
Knowing the yearly cost helps in controlling energy use. The factory can adjust machine run-time or shift planning to cut electricity bills.
Useful for Budget Forecast
Owners and accountants can use this data to prepare yearly budgets. This makes the financial report more accurate and simple.
Application in Textile Sectors
Spinning Mills
Spinning machines like ring frames and blow room machines use heavy power. The calculator helps mill engineers track daily and yearly usage.
Weaving Units
Looms need high-speed motors. Daily and yearly cost estimation helps optimize weaving capacity with cost control.
Dyeing and Finishing
These units use heat and water. Electrical heaters and dryers use high electricity. So, cost checking is vital here.
How This Supports Sustainable Goals
Many textile companies aim for sustainability. Energy saving is part of that goal. By using this calculator, engineers can reduce extra power use. This supports low-cost production and helps reduce the factory’s carbon footprint.
Final Thoughts
Electricity cost affects every part of textile production. The annual electricity cost calculator in the factory helps in smart decision-making. It uses machine power, operating time, working days, and energy rates to give a clear estimate. Every textile engineer, factory manager, or energy auditor should use this tool for better planning. It saves time, money, and resources.
