Yes. The Gruha Jyothi Scheme remains active in 2026-27. Households consuming up to 200 units receive a subsidy, provided they are within their entitlement limit.
If your consumption exceeds **200 units** in a single month, you lose the Gruha Jyothi subsidy for that month and must pay the **full bill** (Energy + Fixed + Tax).
The fixed charge for domestic (LT-2A) connections is **₹145 per kW** per month. This is a mandatory charge even if your consumption is zero.
The P&G (Pension & Gratuity) surcharge is a government-mandated levy to recover retirement benefit contributions. For FY 2026-27, it is approximately **36 paise per unit**.

That’s why a Karnataka electricity bill calculator is such a lifesaver. It lets you plug in your details and get a quick estimate based on the latest tariffs. I’ll break down what it is, how to use it, and the current rates for 2025-26. Stick around, and you’ll be budgeting like a pro.
What is a Karnataka Electricity Bill Calculator?
Think of it as your personal bill forecaster. This online tool uses the tariff rules set by the Karnataka Electricity Regulatory Commission (KERC) to calculate what you might owe.
It’s perfect for residents in Bengaluru, Mysuru, or anywhere in the state. You input your consumer type—like domestic, commercial, industrial, or agricultural—along with units used and connected load.
The calculator factors in energy charges, fixed charges, duties, and even surcharges. Many versions also account for the Gruha Jyothi scheme, which gives free power up to 200 units for eligible households.
No more guessing games. These tools are often on official sites like BESCOM or MESCOM, or reliable third-party apps. They’re free, fast, and help you spot ways to save.
If you’re a homeowner watching your expenses or a shop owner planning ahead, this is your go-to. It shows a breakdown, so you see exactly where your money goes. Plus, it’s mobile-friendly for on-the-spot checks.
How Does the Karnataka Electricity Bill Calculator Work?
It’s all about the math behind KERC’s tariffs. The tool starts with your category, as each has unique rates. For domestic users, it’s often a flat rate now, thanks to recent simplifications. Commercial and industrial have their own flat structures too.
Energy charges are per unit (kWh) consumed. Fixed charges are based on your connected load in kW—basically, the max power your setup can draw. Then add electricity duty, which varies: around 6% for many, but 9% for commercial. Don’t forget the P&G surcharge of 36 paise per unit starting April 2025.
For example, the calculator multiplies units by the rate, adds fixed costs, applies duty and surcharge, and subtracts any rebates like rural discounts or Gruha Jyothi free units. If you’re over 200 units in domestic, you pay full for the excess.
Official calculators from discoms like HESCOM or GESCOM are the most accurate. Third-party ones might miss nuances, so double-check.
Current Tariff Rates in Karnataka for FY 2025-26
KERC updated tariffs in March 2025, effective from April. They reduced energy charges in many categories but hiked fixed ones slightly. This is for FY 2025-26, with plans for minor tweaks in 2026-27 and 2027-28. Rates are uniform across discoms, but rural areas get a 30 paise/unit rebate on energy charges.
Note the P&G surcharge: 36 paise/unit for all. Electricity duty is 6% for domestic and industrial, 9% for commercial, and often waived for agricultural. Gruha Jyothi offers free up to 200 units for domestic LT-1 connections (eligible households with Aadhaar linked).
Here’s a summary. I sourced these from KERC’s latest order to ensure accuracy.
Domestic (LT-1) Tariffs
Domestic rates are now flat, with no slabs after rationalization. Great for simplicity.
| Consumption Slab | Rate (₹/unit) | Fixed Charges (₹/month) |
|---|---|---|
| All Units | 5.80 | 145 per kW |
Add 6% duty, 36 paise surcharge. Rural rebate: 30 paise/unit. Gruha Jyothi: Free up to 200 units if average consumption qualifies.
Commercial (LT-3) Tariffs
For shops, offices, etc. Reduced energy charge helps businesses.
| Consumption Slab | Rate (₹/unit) | Fixed Charges (₹/month) |
|---|---|---|
| All Units | 5.95 | 210 per kW |
Duty at 9%, plus surcharge. No slabs here either.
Industrial (LT-5) Tariffs
Industrial users saw a big drop in energy charges—160 paise less.
| Consumption Slab | Rate (₹/unit) | Fixed Charges (₹/month) |
|---|---|---|
| All Units | 6.60 | 180 per kW |
6% duty, surcharge applies. For HT industrial, rates are similar but with demand charges.
Agricultural (LT-4) Tariffs
For irrigation pump sets (IP sets), rates hiked to cover subsidies.
| Consumption Slab | Rate (₹/unit) | Fixed Charges (₹/month) |
|---|---|---|
| All Units | 8.30 | 60 per kW (or per HP equivalent) |
Duty often 0%, subsidized heavily. Government covers much for farmers up to 10 HP.
These are LT rates; HT has lower per-unit but higher fixed. Check KERC site for updates, as fuel adjustments can add extras.
