LESCO Bill Calculator
Disclaimer: This calculator provides a close estimate based on current LESCO tariff rates. Your final bill may differ slightly, since NEPRA revises rates quarterly through Fuel Price Adjustments (FPA), and additional government charges may apply.
How to Use the LESCO Bill Calculator
Getting your estimate takes less than a minute. Here’s what to do:

Step 1: Find Your Consumed Units
Check your current month’s unit consumption. You can get this instantly via LESCO’s SMS service on your registered mobile number, or by checking your meter directly.
Step 2: Select Your Category (If Applicable)
If you’ve consumed 200 units or fewer for each of the last 6 months, tick the “protected category” checkbox. This determines which tariff slab applies to you and directly affects your rate per unit.
Step 3: Hit Calculate
Click the Calculate button, and the tool will instantly generate a full breakdown: electricity cost, F.C. surcharge, electricity duty, TV fee, GST, N.J. surcharge, and your total estimated bill.
A Quick Reality Check
This estimate does not include the Quarterly Tariff Adjustment (QTR) or FPA, both of which NEPRA applies periodically. Treat the result as a strong approximation — not the exact figure you’ll see on your official bill.
How to Calculate Your Electricity Bill Manually
Prefer to do the math yourself, or want to understand what’s happening behind the calculator? Here’s the logic:
- Take your meter reading for the billing month.
- Identify your connection type — domestic, commercial, or agricultural.
- For domestic connections, determine whether you’re a protected or non-protected consumer (this depends on your consumption history over the last 6 months).
- Find your slab in the tariff tables below, based on total units consumed.
- Multiply units consumed × the per-unit rate for your slab.
- Add fixed charges such as meter rent.
- Add applicable taxes — GST, electricity duty, TV fee, and surcharges.
- Total everything — that’s your estimated bill.
Simple formula: Units Consumed × Rate per Unit = Base Electricity Cost (taxes and surcharges are added on top).

Tips to Lower Your Next LESCO Bill
- Shift heavy appliance use to off-peak hours if you’re on an agricultural or time-of-use connection.
- Stay within the 200-unit protected slab where possible — non-protected rates jump significantly.
- Service your AC and refrigerator regularly — poorly maintained appliances consume noticeably more power.
- Switch to LED lighting across the house; it’s one of the simplest, highest-impact changes.
- Unplug devices on standby — phantom load adds up over a billing cycle.
Why Your Estimate Might Not Match the Final Bill
Your official LESCO bill includes several variable components this calculator can’t fully predict:
- Fuel Price Adjustment (FPA) — revised quarterly by NEPRA based on fuel costs.
- Quarterly Tariff Adjustments (QTR) — periodic rate revisions.
- Government surcharges — which can change with new policy decisions.
- Arrears or previous balances, if any exist on your account.
Because of this, always treat the calculator’s output as a planning tool — and confirm the exact amount against your official e-bill once it’s issued.

The basic calculation is units consumed multiplied by the applicable rate per unit. For example, 200 units at roughly Rs 10 per unit would be around Rs 2,000 before taxes, surcharges, and other applicable charges. Official rates are determined under the applicable electricity tariff.
Not precisely. A bill calculator provides an estimate, while your actual bill may vary because of taxes, surcharges, tariff adjustments, fuel price adjustments, and other applicable charges.
The process is the same throughout LESCO’s service area. Enter your reference number or customer ID on the relevant LESCO billing portal to access your bill details.
