MEPCO Bill Estimator – Estimate Your Electricity Bill Online
Use the MEPCO bill estimator above to build a transparent estimate of your next electricity bill. Enter your units or meter readings, choose the consumer category shown on your account, and provide peak/off-peak readings if you have a Time of Use (TOU) meter. The tool then applies the tariff assumptions displayed on the page and separates the main parts of the estimate so you can see what is driving the result.
MEPCO Bill Estimator
Estimate residential energy and fixed charges using the February 2026 tariff schedule.
Your estimate
| Estimated component | Amount |
|---|
Not an official bill: this result estimates notified residential energy and fixed charges only. It does not include GST, electricity duty, TV fee, FCA/FPA, QTA, surcharges, arrears, installments, late-payment charges, subsidies, credits, or account-specific adjustments. Your official MEPCO bill can therefore be substantially different.
Tariff data used: Government-applicable residential schedule dated 11 February 2026. Verify the schedule applicable to your billing month.
The result is useful for budgeting, comparing one month with another, and spotting a reading or category that deserves a closer look. It is not an official MEPCO bill and it cannot see your private billing record. Your actual amount may be different because MEPCO bills include account-specific information, taxes, arrears, late-payment entries, and periodic adjustments that may not be known when you make the estimate.
What the estimator calculates
An electricity bill is not just units multiplied by one number. The estimator starts with consumption and then applies the selected tariff structure. Depending on the information you enter, it can show:
- estimated units from a previous and current meter reading;
- the applicable consumption band or bands;
- separate peak and off-peak consumption for a TOU account;
- the energy or variable-charge component under the displayed tariff;
- fixed or minimum charges where the selected schedule requires them;
- an estimated subtotal before items that cannot be predicted reliably;
- clearly labelled allowances or exclusions for taxes, adjustments, arrears, and payment-related charges.
The tool should always show the tariff effective date alongside the estimate. At the time this page was fact-checked, the relevant reference included NEPRA’s decision dated 11 February 2026 and the notification issued in February 2026 for the consumer-end tariff of XWDISCOs, including MEPCO. A later notification, government policy decision, court order, or periodic adjustment can change the amount payable. Check the effective date shown by the calculator and compare it with the tariff period on your bill.
Start with the correct units
One electricity unit generally means one kilowatt-hour (kWh). On an ordinary cumulative meter, calculate units by subtracting the previous reading from the current reading:
Units consumed = Current meter reading − Previous meter readingFor example, if the previous reading was 28,440 and the current reading is 28,612:
28,612 − 28,440 = 172 unitsEnter readings from the same register and check the reading dates printed on the bill. A billing cycle of 35 days can naturally contain more consumption than a 28-day cycle. Do not enter a voltage, current, maximum-demand value, or an error code in place of the kWh register.
If your bill includes a multiplying factor, the difference between the register readings may need to be multiplied before it becomes billed units. The factor printed on your own bill is the relevant one; never copy a neighbour’s factor or guess it from the meter’s appearance. If you are unsure whether a factor applies, use the bill’s units field as the starting point and ask MEPCO to explain any discrepancy.
Read and photograph the meter only from a safe position. Never break a seal, open the enclosure, touch exposed wiring, or install a testing device yourself. If the meter is hot, sparking, damaged, or surrounded by unsafe wiring, move away and report the safety issue through the official channel.
Choose the right consumer category
The calculator cannot determine your official category from this month’s units alone. Select the category printed on your MEPCO bill and use the account history to check whether the selection makes sense.
Protected residential
Under the residential tariff definition, a protected consumer is generally a non-TOU residential consumer whose consumption is 200 units or less consistently over the preceding six months. This is a billing classification based on the account’s history; it is not simply a discount that can be switched on by entering a low number in the estimator.
For an estimate, select protected only when the bill identifies the connection that way or when you are deliberately modelling a qualifying account. If you used 180 units this month but your recent history does not meet the applicable rule, the official bill may use a non-protected category. The calculator should warn that a prediction based on assumed protected status is provisional.
The February 2026 NEPRA schedule included protected bands for 1–100 and 101–200 units. It also included separate lifeline bands and other residential categories. Do not treat lifeline, protected, and non-protected as interchangeable labels. The bill’s tariff description and the current notified schedule control.
Non-protected residential
Use non-protected when the bill shows that classification or when the account does not meet the current protected-consumer conditions. Non-protected does not mean illegal, irregular, or suspected of theft. It is a tariff category, and a legitimate household may fall into it because of its consumption history or metering arrangement.
The schedule may divide non-protected consumption into several bands. The estimator therefore needs to apply the displayed slab rules to portions of the units rather than multiplying every unit by whichever rate appears at the top of the table. If you cross a band, the result can move more sharply than a simple month-to-month units comparison suggests.
Lifeline and other categories
If your bill says lifeline, commercial, general services, agricultural, temporary supply, or another category, choose that category only if the calculator supports it and the displayed schedule is intended for that account. A residential estimate cannot safely be reused for a commercial or specialised connection. If the tool does not support the category on your bill, use the result only as a units forecast and obtain the official tariff calculation from MEPCO.
TOU meters: enter peak and off-peak readings separately
A TOU meter records energy in more than one register. Combining the registers before applying the tariff loses information that can affect the estimate. Enter the previous and current peak readings in the peak fields and do the same for off-peak readings.
For example:
Peak units = 4,260 − 4,210 = 50 units
Off-peak units = 8,790 − 8,670 = 120 units
Total units = 50 + 120 = 170 unitsThe calculator should apply the applicable peak component to the 50 peak units and the off-peak component to the 120 off-peak units. It should not use a single protected residential rate for both registers. A TOU connection is billed under its own arrangement, and low total consumption does not automatically turn a TOU account into a protected non-TOU account.
Check that the bill’s meter type and tariff code match the option you selected. If one register has been estimated, is unreadable, or appears to have rolled over, do not present the output as a precise forecast. Record the displayed values, keep dated photographs, and ask MEPCO for a reading or billing-history verification.
Fixed charges and sanctioned load
Some tariff schedules include fixed or minimum charges in addition to variable energy charges. The amount can depend on the category, metering arrangement, sanctioned load, or other terms in the applicable schedule. Sanctioned load is the load MEPCO has approved for the connection; it is not necessarily the same as the number of appliances currently running.
Enter the sanctioned load only when it is printed on the bill or confirmed by MEPCO. The estimator should use it to select a fixed-charge rule where the current schedule provides one. Do not calculate a fixed charge by multiplying kW by an arbitrary rate found in an old article. If the load is blank, the account has recently changed tariff, or the connection is subject to a special arrangement, show that fixed charges could not be confirmed rather than inventing a value.
Fixed charges also explain why a bill may not fall in direct proportion to units. A household that uses very little energy can still have a fixed or minimum amount under the applicable terms. Conversely, adding a fixed charge twice—once in a tariff rule and once as a manual “allowance”—would overstate the estimate. The result should identify whether fixed charges are included, excluded, or based on an assumption.
Why the official bill can differ
The calculator is intentionally transparent about the items it cannot know. MEPCO’s billing documents identify several separate components, including variable charges, fixed charges, electricity duty, GST, arrears, late-payment surcharge, and other charges. Periodic adjustments may be shown on the bill as well.
Fuel Charges Adjustment (FCA)
FCA is a periodic adjustment connected with the fuel-cost component used in the approved tariff. It can be notified after the electricity was consumed and may be reflected in a later billing month, subject to the notification’s applicability and any exclusions. A consumption estimate made today cannot safely assume the FCA line that will appear on a future bill.
Quarterly Tariff Adjustment (QTA)
QTA is another periodic adjustment that can change the amount collected in a billing period. It may be applied to eligible consumer categories under the notified decision. The estimator may show energy charges without QTA or use a separately labelled input if the page has a current, verified adjustment value. It must not hide QTA inside an unexplained per-unit rate.
Taxes, duties, and surcharges
GST, electricity duty, withholding tax where applicable, financing or policy surcharges, and other government-imposed items can depend on the category and the billing month. The exact treatment is not the same for every consumer. The calculator should either use verified current rules or state that these items are excluded from the displayed subtotal.
Arrears, deferred amounts, and late payment
Arrears are unpaid amounts carried from an earlier bill. A deferred amount or approved installment arrangement can also change what is payable now. Late-payment surcharge depends on payment timing and cannot be inferred from units. Enter these items only when the page offers explicit fields and you are copying them from the current bill. Do not add arrears to a forecast of ordinary monthly usage unless you want to model the amount payable on that specific account.
These exclusions are not defects in the estimator. They are a safeguard against making a tidy-looking number appear official. If the calculator shows a range or a subtotal, read its labels before comparing it with the “amount payable within due date” on a MEPCO bill.
Worked examples
Example 1: a non-TOU household
Assume a non-TOU residential bill shows a previous reading of 28,440 and a current reading of 28,612. The consumption is 172 units. The customer checks the bill and sees that the account is protected, with a qualifying history. The estimator applies the protected tariff bands shown for the selected effective date: the first band is charged under its displayed rule and the remaining units are charged under the next applicable band.
The important output is not an invented final rupee promise. It is the breakdown: 172 units, the bands used, the variable-charge subtotal, any included fixed amount, and the list of taxes or adjustments not included. The customer can now compare the meter and category with the official bill and understand why adding a tax or adjustment later may change the final payable amount.
If the same customer selects non-protected by mistake, the tool should make the category assumption visible. The two estimates may be materially different even though the units are identical. That difference is a reason to verify the bill’s classification—not evidence that either estimate is an official correction.
Example 2: a TOU household
Assume the peak register rises by 50 units and the off-peak register rises by 120 units. The total is 170 units, but the estimator keeps the 50 and 120 values separate and applies the displayed TOU components independently. If the customer instead enters only “170” in a single residential field, the result can be misleading because it has lost the time-of-use split.
The customer should compare the output with the meter type, tariff code, and reading dates on the bill. If the tool’s tariff effective date is earlier than the bill’s schedule, the customer should not use the rupee subtotal for payment planning until the tariff data is updated.
Example 3: adding a bill’s arrears
Suppose the estimator forecasts the next ordinary cycle from 220 units, but the current bill also shows an earlier unpaid balance. The consumption forecast describes the new cycle only. If the customer wants to model the amount payable on the current account, they may enter the arrears in a separate field, provided the value is copied from the bill. The result should label the combined figure as an estimate including arrears and should not imply that the arrears came from this month’s electricity use.
How to use the result responsibly
First, check the inputs displayed beside the result: meter type, category, units, reading dates, sanctioned load, and tariff effective date. Then review the breakdown rather than looking only at the large total. If the estimate is unexpectedly high, change one assumption at a time and see whether the movement comes from units, slab selection, TOU allocation, fixed charges, or an optional bill adjustment.
Use the estimate to decide whether to photograph the meter, investigate a new appliance, plan a payment, or compare the next bill with the forecast. Keep the current bill, previous bill, and dated meter image together. If the official bill does not reconcile, contact MEPCO or use the PITC complaint channel with the 14-digit reference number, readings, dates, and a description of the mismatch.
Do not delay a bill payment solely because an independent estimate is lower. The due date, payable amount, and late-payment rules on the official bill remain the relevant payment instructions. If you dispute a reading or category, ask MEPCO how to handle the undisputed amount while the complaint is reviewed.
Frequently asked questions
Is this an official MEPCO bill calculator?
No. See MEPCO Bill is an independent information website. This estimator provides a calculation from the inputs you supply and the tariff assumptions displayed on the page. It does not retrieve, issue, or alter an official MEPCO bill.
Can I estimate a bill from units alone?
You can estimate the energy component, but units alone do not identify the consumer category, slab treatment, TOU split, fixed charge, taxes, adjustments, arrears, or payment status. Add the account details shown on your bill for a more useful result.
Why is my bill higher than the estimator?
Check the tariff effective date, protected or non-protected category, billing-period length, meter factor, fixed charges, FCA, QTA, taxes, arrears, and late-payment entries. A later actual reading can also include consumption that was not captured by an earlier estimated bill.
Does entering 200 units make me protected?
No. Protected status depends on the applicable definition and recent consumption history for a qualifying non-TOU residential account. Use the status printed on the bill or ask MEPCO to verify the account.
Can the estimator calculate a solar or net-billing account?
Only if the page explicitly supports the relevant import, export, and net-billing rules. Do not use an ordinary residential input for a solar account and assume it includes export credits or imported-energy treatment.
What tariff date should I use?
Use the effective date shown by the estimator and compare it with the tariff applicable to the bill month. The February 2026 NEPRA schedule is a reference for this page’s fact-checking, not a permanent rate table. Tariff and adjustment data must be maintained when official notifications change.
What should I do if my meter reading is wrong?
Photograph the meter safely, preserve the bill and earlier readings, and contact MEPCO or PITC with the reference number and dates. Ask for a reading and billing-history check. Do not open, tamper with, or bypass the meter.
