Electrical Appliance Electricity Consumption in Pakistan: Watts, Units and Running Costs

To estimate appliance electricity consumption in Pakistan, multiply input watts by minutes used and divide by 60,000. That gives electricity units, or kWh. Multiply those units by your applicable energy rate. A 2,000W geyser heating continuously for 30 minutes uses 1 unit.

The kettle runs for a few minutes before school. The iron comes out for uniforms. The geyser stays switched on because someone else needs a shower. These routines matter more than a wattage list on its own.

This running-cost guide is part of our complete electrical appliances buying guide for Pakistan. Start with that main guide for advice on choosing appliances, capacity, budget and warranty.

Ratings and tariff sources checked: 9 October 2026. The calculations below use verified specifications and stated usage assumptions. They are estimates, not readings from appliances we have tested.

What is the difference between watts, kilowatts and electricity units?

Watts (W) describe power: how quickly an appliance uses energy while operating. Kilowatts (kW) are watts divided by 1,000. Kilowatt-hours (kWh) measure energy used over time. On an electricity bill, 1 unit means 1 kWh.

A 2,000W heating element draws about 2kW when energised. Run it continuously for half an hour and it uses 1kWh. Run it for a full hour and it uses 2kWh.

A high wattage does not automatically mean a high monthly cost. Duration and frequency matter too. An appliance used briefly can consume less energy than a smaller load left running for hours.

How do you calculate electricity units from watts and minutes?

Use this formula:

Units per use = input watts × operating minutes ÷ 60,000

Then work out the month:

Monthly units = units per use × number of uses in the billing period

Estimated energy charge = monthly units × applicable rupees per unit

Here is a kettle example:

1. Read the input rating. The Westpoint WF-578 is listed at 1,850W.
   
   
2. Time your normal boil. For this example, assume 3 minutes.
   
   
3. Calculate one use: 1,850 × 3 ÷ 60,000 = 0.0925 units.
   
   
4. At four uses a day for 30 days: 0.0925 × 120 = 11.1 units.
   
   
5. At the dated example rate of Rs33.10 per unit: 11.1 × 33.10 = Rs367.41 in energy charges.

Three minutes is a calculation assumption, not a tested boiling time. Your water quantity, starting temperature and kettle will determine the actual duration. Use your meter's billing dates too; a 30-day month is only a convenient example.

Which wattage should you use for a geyser, iron, kettle or microwave?

Use the appliance's electrical input rating. Check its label, manual or a specification that clearly identifies power consumption.

These are exact-model examples, rather than a claim that every appliance in each category uses the same power.

NasGas confirms the NEG-50 rating on its manufacturer specification page. Westpoint also lists 1,850W for the WF-578. The iron's figure comes from its linked Powerhouse Express specification.

Why is the microwave's advertised wattage easy to misread?

Samsung's MG23K3515AK/D2 specifications separate 800W output from 1,250W microwave power consumption.

For a five-minute full-power estimate:

• Using the input: 1,250 × 5 ÷ 60,000 = 0.1042 units.
  
  
• Using the cooking output: 800 × 5 ÷ 60,000 = 0.0667 units.

The second calculation understates the input-based estimate by 36%. That is a calculation error, not evidence that the oven performed badly.

The same Samsung page lists separate grill and maximum ratings. Select the figure for the mode you use. This example follows the manufacturer's /D2 version; check the complete model suffix on your own appliance.

There is a local example of why this check matters. Our Dawlance DW-210 Solo listing describes 700W power output. That alone is insufficient to calculate its electricity use. Ask for the electrical-input label or manual rather than treating 700W as the socket demand.

What does one electricity unit cost in Pakistan in 2026?

There is no single all-in rate that fits every household.

For a dated reference, the IESCO tariff guide, checked on 9 October 2026, displays the residential schedule headed SRO 279(I)/2026, February 2026. Selected entries are:

These are selected schedule rates, not final bill totals. Fuel and quarterly adjustments, surcharges, taxes and other applicable entries can change the amount payable. Use your own supplier's current bill and tariff category for a personal estimate.

This guide uses Rs33.10 per unit for the appliance examples: the variable charge shown for the 201–300-unit unprotected category. It is an example energy rate, not a universal electricity price.

How many units could these appliances use over 30 days?

The table assumes operation at the listed input rating for the stated time. For thermostatic appliances, that means heating time, rather than every minute they remain plugged in.

Together, these routines use an estimated 51.75 units, costing Rs1,712.93 at the example energy rate.

Keep the unrounded units when calculating costs, then round the final rupee amount. The combined figure covers only these four routines. It excludes other household loads, standby use and bill adjustments.

What changes the calculation in an ordinary Pakistani home?

Does leaving a storage geyser on mean it heats continuously?

No. A thermostat can turn the element off once the tank reaches its set temperature, then restart it as water cools or hot water is drawn.

For the 2,000W example:

• 30 minutes of actual element heating daily: 30 units in 30 days.
• 60 minutes daily: 60 units in 30 days.

At Rs33.10 per unit, those energy estimates are Rs993 and Rs1,986. The extra half-hour of daily heating doubles this particular estimate.

Neither figure tells you how long a full 50-litre tank will take to heat. Colder incoming water, the temperature setting, hot-water withdrawals and heat loss all affect heating time.

For a family shower routine, record when the element actually heats, or measure energy across the full routine. “The switch was on for eight hours” does not provide the same information.

What should you count when ironing school uniforms?

Count the heating and reheating during the whole job. The iron may cycle while you lay out a shirt, turn a sleeve or fold clothes.

The 15-minute, 2,200W calculation gives 0.55 units per session if heating continues throughout. It is a full-rated estimate, not a claim that every 15-minute ironing session uses exactly 0.55 units.

Measure a complete batch from a cold start. Comparing one iron after it has warmed up with another from cold gives an unfair result. The same applies when comparing a steam iron with a dry iron: compare the same clothes and finish.

Can a few extra kettle boils noticeably change the month?

Yes, through repetition. Under the same three-minute assumption:

• Four boils daily use 11.1 units over 30 days.
  
  
• Eight boils daily use 22.2 units.

The difference is Rs367.41 at the example energy rate. These are different use counts, not measured savings from changing the water level.

For tea, coffee or hot water between meals, time the amount you actually need. Stay within the kettle's minimum and maximum fill marks. A full kettle and a small permitted fill should not automatically be assigned the same boiling time.

Why can one extra unit change more than the energy charge for that unit?

Because the household's billing category or slab can change.

IESCO's displayed schedule gives the previous-slab benefit only to protected residential consumers. K-Electric's billing explanation also describes unprotected consumption being charged within a single slab.

Here is a worked example using that rule and the displayed 2026 rates. Assume an unprotected, non-TOU residential account with 3kW sanctioned load.

The calculated subtotal rises by Rs1,194.46. Taxes and adjustments are excluded from both rows.

This does not mean one unit always costs Rs1,194.46. It shows why multiplying an appliance's extra unit by the old rate can miss a slab change.

For a household usually finishing comfortably within one slab, a constant-rate estimate is useful. Near a boundary, compare the household bill calculation before and after adding the appliance's units.

What if your household is close to 200 units?

Suppose the rest of the home uses 198 units, then a geyser adds 30 units. The estimated total becomes 228 units.

That can affect protected eligibility as well as the current month's charge. The protected rules described by K-Electric cover qualifying non-TOU homes with sanctioned load below 5kW and consumption within 200 units in the current month and the preceding six months.

Check the history on your bills. One lower-consumption month does not by itself establish that the household has regained protected status.

Do peak and off-peak hours change an appliance's running cost?

They can, if the account is billed under time of use (TOU). Check whether your bill lists separate peak and off-peak units.

Using the TOU rates on IESCO's displayed schedule, shifting a 1-unit heating session from Rs46.85 peak to Rs34.53 off-peak changes the energy charge by Rs12.32. Across 30 identical sessions, the calculated difference is Rs369.60, before adjustments.

The appliance still uses the same 30 units in that example. The saving comes from the rate, not lower energy consumption.

For K-Electric TOU customers, its published timetable lists:

• April–October: 6:30pm–10:30pm peak.
• November–March: 6:00pm–10:00pm peak.

Confirm your own distribution company's timings. An ordinary non-TOU slab account does not get a cheaper base unit merely because the kettle runs after 10:30pm.

Why will your bill still include charges that this appliance calculation misses?

Your electricity bill can include a connection-related charge as well as units used.

Under the displayed 2026 residential schedule, non-TOU fixed charges depend on sanctioned load and the applicable category. For the 3kW, 201–300-unit example, that is 3 × Rs350 = Rs1,050 per month.

Sanctioned load is the connection's approved load. It is not simply the geyser's wattage. Adding a 2kW geyser does not automatically mean multiplying 2 by the fixed-charge rate.

TOU fixed charges follow a different basis: the higher of 50% of sanctioned load or the recorded maximum demand indicator (MDI), under the published rule. Refer to your bill's demand entry; adding appliance ratings together is not a substitute for its recorded MDI.

Dividing the entire bill by the month's units gives an average cost. It can be useful for budgeting, but fixed charges, earlier-period adjustments and arrears can make it misleading as the cost of one additional appliance session.

How can you measure your own appliance's consumption?

A measurement answers the questions that a nameplate cannot: how long the thermostat heats, what the lower power setting does and how much your actual routine uses.

1. Identify the exact model and mode. Record the input rating and, for a microwave, whether you use microwave, grill or combination mode.
   
   
2. Measure safely. Use a suitable, correctly rated energy meter for a compatible plug-in appliance. Have a qualified electrician measure a hardwired geyser; do not adapt its wiring yourself.
   
   
3. Record the complete task in kWh. Include warm-up and thermostat cycling. A momentary watt reading is not the total energy for the job.
   
   
4. Repeat comparable tasks. Keep the water quantity, clothes batch or food portion consistent, and record differences rather than hiding them.
   
   
5. Multiply by your real use count. Use the number of sessions in the billing period, then check whether the resulting household total crosses a slab boundary.

A useful record is: model, mode, task quantity, starting conditions, date, duration and measured kWh. Keep estimated and measured figures in separate columns.

For a first estimate, use the formulas in this guide. For a claim about your own appliance's consumption, use the measurement.
