How to Calculate Your Electricity Bill 2026
Electricity costs are rising, but many state governments in India provide relief through free unit schemes. Whether you are under the TNEB (Tamil Nadu) 100-unit free scheme or Delhi's 200-unit subsidy, our calculator helps you estimate your monthly expenditure instantly.
State-wise Free Unit Schemes in India
Different states have different subsidy structures for domestic consumers:
- Tamil Nadu: First 100 units are free for all domestic consumers.
- Delhi: Consumers using up to 200 units get a 100% subsidy.
- Punjab & Karnataka: Schemes like 'Gruha Jyothi' provide up to 200-300 units free based on specific conditions.
Slab-Based Calculation Formula
Most Electricity Boards (EBs) use a slab system. For example:
- 0 - 100 Units: ₹0.00 (If free)
- 101 - 200 Units: ₹3.50/unit
- 201 - 500 Units: ₹6.50/unit
Our calculator simplifies this by letting you input your average slab rate after deducting the free units allowed in your region.
Tips to Reduce Your Electric Bill
- Use Energy Star Ratings: Always choose 5-star rated appliances to save up to 30% on consumption.
- Switch to LED: Replacing old bulbs with LED lights significantly reduces your hourly unit usage.
- Monitor Peak Hours: Some states charge extra during peak evening hours; try to use heavy appliances like washing machines during the day.
