Planning your finances starts with knowing your electricity costs. Whether you want to reduce your power bill or estimate monthly expenses, this Electricity Bill Calculator gives you an instant estimate — simply enter your units consumed and the rate charged per unit by your electricity provider.
What Is an Electricity Bill Calculator?
An electricity bill calculator estimates your monthly electricity charges based on the number of units (kWh) consumed and the rate per unit set by your electricity distribution company (DISCOM). This helps you plan your monthly budget, identify high-usage appliances, and track savings from energy-efficient habits.
Electricity Bill Formula
Electricity Bill = Units Consumed × Rate per Unit
Where: 1 Unit = 1 kWh (using a 1000W appliance for 1 hour)
Note: Your actual bill may include additional charges like meter rent, fixed charges, and applicable taxes — add these on top of the base calculation.
Example Calculation
Scenario: You consumed 250 units this month. Your state rate is ₹6.50 per unit.
- Base Bill = 250 × ₹6.50 = ₹1,625
- Meter rent + fixed charges = ~₹100 (approximate)
- Estimated Total Bill = ₹1,725

Understanding Electricity Slabs in India
Most Indian states use a slab-based tariff. The first 100 units may cost ₹3/unit, the next 200 at ₹5/unit, and above 300 at ₹7/unit. This means your effective rate increases as consumption rises — encouraging conservation.
