Chargeable weight vs actual weight: why a 3 kg parcel bills as 5 kg

A parcel that reads 3 kg on your scale can still be charged as 5 kg. That is not an error on the invoice and it is not a hidden surcharge. It is chargeable weight, and a delivery van runs out of space long before it runs out of lifting capacity, which is the whole reason the rule exists.

What follows is the exact arithmetic QCS applies, with the published Lahore rates in it, so you can take any charge on your statement and reproduce it in about a minute.

The two weights, and which one you actually pay for

Every parcel has two weights. One is the figure your scale shows, which the tariff calls actual weight. The other is worked out from the carton rather than the contents, and that is dimensional weight, also called volumetric weight. You are charged on whichever of the two is larger, with one threshold that decides when the comparison happens at all.

How the dimensional figure is worked out

Measure the outside of the box in centimetres. Multiply length by width by height, then divide the result by 5000. The answer is in kilograms.

The 5000 divisor is the convention across the courier, express and parcel trade rather than a QCS invention. It encodes a density assumption: one cubic metre is a million cubic centimetres, so dividing by 5000 treats that cubic metre as weighing 200 kg. Dimensional weight is the general name for the method, and the divisor is not universal, so a figure worked out for one carrier will not always reproduce on another.

Which weight wins

The tariff is specific here and it is worth reading twice, because the threshold is the part sellers miss.

• Actual weight of 5 kg or less, with dimensions supplied: the basis is the larger of the actual and the dimensional weight
• Actual weight above 5 kg: the basis is the actual weight, and the size of the box stops mattering
• No dimensions supplied: the basis is the actual weight at booking, and the warehouse may re-measure on arrival

Rounding only ever goes up

Once the basis is settled it is rounded up to the next half kilo. Never to the nearest. A basis of 0.51 kg bills as 1.0 kg. A basis that lands on exactly 2.00 kg bills as 2.0 kg, because an exact multiple does not round up. One gram over that, at 2.001 kg, becomes 2.5 kg and costs PKR 40 more inside Lahore City.

The tariff example, worked all the way through

Take a box measuring 40 by 30 by 20 centimetres that weighs 3 kg on the scale.

1. 01The volume is 40 by 30 by 20, which is 24,000 cubic centimetres
2. 02Divided by 5000, the dimensional weight is 4.8 kg
3. 03Actual weight is 3 kg, under the 5 kg threshold, so the larger of the two applies
4. 04The basis is therefore 4.8 kg, which rounds up to 5.0 kg
5. 05Five kilograms is ten units of half a kilo
6. 06Lahore City is PKR 180 for the first unit and PKR 40 for each of the nine that follow
7. 07PKR 180 plus PKR 360 gives PKR 540

So a 3 kg parcel costs PKR 540 inside Lahore City, the same as a parcel that genuinely weighed 5 kg. The carton did that, not the contents.

What each half kilo costs in Lahore

Standard and express both step by half a kilo, and they step at different rates. Standard opens at PKR 180 and steps by PKR 40. Express or same day opens at PKR 250 and steps by PKR 50, and the parcel has to be collected before 13:00 to qualify, which is set out with the rest of our service options. Lahore Extended Area adds a flat PKR 50 per parcel, applied once, on standard and express alike.

Read each line as chargeable weight, then Lahore City, extended area, express, and express into the extended area.

• Half a kilo: PKR 180, PKR 230, PKR 250, PKR 300
• One kilo: PKR 220, PKR 270, PKR 300, PKR 350
• 1.5 kg: PKR 260, PKR 310, PKR 350, PKR 400
• 2.0 kg: PKR 300, PKR 350, PKR 400, PKR 450
• 2.5 kg: PKR 340, PKR 390, PKR 450, PKR 500
• 3.0 kg: PKR 380, PKR 430, PKR 500, PKR 550
• 3.5 kg: PKR 420, PKR 470, PKR 550, PKR 600
• 4.0 kg: PKR 460, PKR 510, PKR 600, PKR 650
• 4.5 kg: PKR 500, PKR 550, PKR 650, PKR 700
• 5.0 kg: PKR 540, PKR 590, PKR 700, PKR 750

The table stops at 5.0 kg but the rates do not. Above that the steps simply continue. An 8 kg parcel is sixteen units, so Lahore City is PKR 180 plus fifteen steps of PKR 40, which is PKR 780. The same parcel sent express into the extended area is PKR 250 plus fifteen steps of PKR 50 plus the flat PKR 50, which is PKR 1,050. There is no cap and there is no separate heavy band.

Every figure above is inclusive of sales tax and the fuel adjustment. Nothing is added at invoice.

Where the extended area begins

The flat PKR 50 is decided by the zone the delivery address falls into, never by the weight. Eleven named points mark where Lahore City ends: beyond Central Park on Ferozepur Road, beyond Bahria Orchard on Raiwind Road, beyond Mohlanwal on Multan Road, beyond Bahria Town and beyond Jallo Park on Canal Road, beyond Rachna Town towards Kala Shah Kaku and beyond Manawan towards Wagah on G.T. Road, beyond Begum Kot, beyond Green Land Swimming Pool on Sagian Road, beyond Lahore School of Economics on Barki Road, and beyond Dera Chahal on Bedian Road. The coverage map carries the same eleven points drawn out.

Four things sellers get wrong

Padding a small item into a large carton

A 200 gram phone case in a 30 by 25 by 15 cm box has a dimensional weight of 2.25 kg, which rounds to 2.5 kg and bills at PKR 340 in Lahore City instead of PKR 180. The filler cost PKR 160, every time that parcel goes out.

Assuming a heavy parcel escapes the rule

It does, but only once the scale reads more than 5 kg. A 7 kg parcel in a 10 by 10 by 10 cm box has a dimensional weight of 0.2 kg, and the tariff ignores it completely. You are billed on 7 kg, which is fourteen units, PKR 700 inside Lahore City.

Leaving the dimensions off the booking

Book without dimensions and the parcel is priced on actual weight alone. That is not a loophole. The weight and dimensions recorded at our Gulberg warehouse are what the final charge is based on, and a re-measure there writes a fresh charge snapshot against the order while preserving the original. Booking it accurately is simply the version where nothing on your statement surprises you.

Reading the charge as a rate per kilo

It is a first unit plus a step, not a rate per kilo, and the difference is large at the bottom of the scale. At half a kilo you are paying PKR 360 per kilo. At 5.0 kg you are paying PKR 108 per kilo. Heavier parcels are better value per kilo, which is why splitting one order into two boxes almost always costs more than sending one.

Five ways to bring the figure down

• Use the smallest box the item survives in. Air is the most expensive thing you can ship
• Measure the carton rather than the item, and measure the outside of it
• Bring the longest side down where the item allows it. Halving any one side halves the dimensional weight outright
• Watch the half kilo boundary. A basis of 2.6 kg and a basis of 3.0 kg cost exactly the same, so trimming down to 2.5 kg is worth far more than trimming to 2.6 kg
• Remember express steps at PKR 50 rather than PKR 40, so weight costs more on a same-day parcel at every single step, not only at the first unit

When the figure becomes final

A calculator quote is indicative. The charge that reaches your statement is worked out from the weight and dimensions recorded at the warehouse, against the version of the rate card that was in force on the day you booked. Publishing a new rate card never reprices a parcel booked before it. And a parcel that is not delivered is not charged at all: a failed delivery or a return costs nothing, which is one of the terms the published tariff sets out in full.

If a charge does not reproduce when you work it through yourself, raise a dispute on that order in the merchant portal. We will show you the measurement it came from and the snapshot it was priced against.
