How this AP electricity bill calculator works
Andhra Pradesh electricity charges for low-tension (LT) consumers are set by the Andhra Pradesh Electricity Regulatory Commission (APERC). For FY 2026-27, energy charges are applied in slabs based on units consumed, with additional fixed or demand charges depending on the consumer category. This calculator maps your usage inputs to those published LT tariff schedules so you can estimate the energy and fixed portions of a monthly bill before you open your DISCOM statement.
Start on the Calculator tab: choose your category, enter units (and load or ToD details when asked), then review the break-up of slab-wise energy charges and other applicable components. The Domestic, Commercial, Industry, Agriculture, and Others tabs show the same APERC rate tables used by the engine, so you can compare slabs without leaving the page. Other Charges covers items such as delayed payment surcharge, reconnection, and meter-related fees listed in the tariff order.
Understanding APERC LT tariff slabs
Domestic LT supply in Andhra Pradesh typically uses a telescopic structure: lower monthly consumption stays in cheaper energy-charge bands, while higher usage fills higher bands. Commercial and industrial LT categories may use different slab edges, demand charges, or Time-of-Day pricing. Agricultural and institutional categories follow their own APERC schedules, including free or concessional quotas where the tariff order provides them.
Knowing which slab your units fall into helps you plan usage—for example, shifting non-essential load can keep a household below a costlier threshold. Always match the category printed on your bill (and your connected load) so the estimate reflects the correct schedule. Rates on this site follow the APERC LT order for FY 2026-27, effective from 25 March 2026 as published for this app.
Tips for a useful estimate
- Copy units from a recent bill or meter reading for the same billing period you want to check.
- Select the exact LT category shown on your bill—not a nearby label that sounds similar.
- Enter connected load or contracted demand when the form asks; fixed or demand charges depend on it.
- For ToD tariffs, split peak and off-peak units the way your meter records them.
- After estimating, pay only through official APEPDCL, APCPDCL, or APSPDCL websites linked from the Pay Bill page.
Units, load, fixed charges and slabs
One unit is one kilowatt-hour (kWh): a 1,000-watt appliance running for one hour. Load is the sanctioned or connected capacity of your service in kW (or HP for some agricultural categories) and drives the monthly fixed charge. Slabs are bands of monthly units; under a telescopic tariff each band is priced separately, so only the units above a boundary attract the higher rate.
The calculator estimates energy charges from your units, fixed charges from your load, and customer charges where the schedule specifies them. It does not add electricity duty, meter rent, delayed payment surcharge, arrears or subsidy credits.
Why the calculated amount may differ from the final bill
Your DISCOM bill can include items this tool cannot know: subsidies, taxes and duty, meter charges, arrears, provisional-reading adjustments, or a billing period that is not one calendar month. Treat the result as a planning estimate and pay only on official DISCOM portals.
Frequently asked questions
How can I calculate my AP electricity bill?
Select the LT category printed on your bill, enter monthly units (kWh) and connected load when asked, then calculate. The tool applies the published APERC FY 2026-27 energy, fixed and customer charges. For a household, use the domestic calculator; shops and offices should use the commercial calculator.
What does one unit of electricity mean?
One unit is one kilowatt-hour (kWh). It is the energy used by a 1,000-watt appliance running for one hour. Your bill’s units are usually present meter reading minus previous meter reading.
Is this an official AP electricity calculator?
No. This is an independent, unofficial estimator. It is not affiliated with APERC, APSPDCL, APCPDCL, APEPDCL or the Government of Andhra Pradesh. Always confirm rates and pay dues on official DISCOM websites.
Why is my actual bill different?
Official bills can include electricity duty, meter rent, subsidies, rebates, delayed payment surcharge, arrears, or adjustments for estimated readings. A wrong category, load or billing-period length also changes the result. Compare line items, not only the total.
Which DISCOM serves my district?
Andhra Pradesh is served by APEPDCL (eastern districts), APCPDCL (central) and APSPDCL (southern). Use the Pay Bill page to find your district, or open the APSPDCL, APCPDCL and APEPDCL reference pages.
How do I pay my AP electricity bill online?
Open your DISCOM’s official payment page from this site’s Pay Bill section, enter your 13-digit service number, verify the amount and pay by UPI, net banking or card. Payments never happen on this website.
Does the calculator include subsidies and arrears?
No. Subsidies, arrears, electricity duty and most miscellaneous charges are account-specific and appear only on the official bill. The estimate covers published energy, fixed and customer charges for the selected LT category.
What tariff year is used?
This site uses the APERC LT retail supply schedule for FY 2026-27, effective 25 March 2026 as transcribed for this app. If a later order changes rates, the official tariff order and your DISCOM bill take precedence.
