How courier pricing works: weight, zone and service level
Almost every carrier in Pakistan prices a parcel from three inputs: chargeable weight, zone and service level. Here is the formula, the two rules that differ between carriers, and the fees to ask about.
Courier pricing in Pakistan looks arbitrary until you know the three inputs it is built from. Almost every carrier in the country prices a parcel from its chargeable weight, the zone it is going to, and the service level chosen. Once you can work out those three for a parcel in your hand, you can predict the charge and spot a wrong one.
This explains the mechanics generally. Where a specific figure is needed, the examples use the published QCS Lahore tariff, because inventing a competitor's number would be worse than using a real one.
Input one: chargeable weight, which is rarely the scale weight
A parcel has two weights. The scale weight, and a weight worked out from the box. You are charged on whichever is larger, because a van fills up by volume long before it runs out of lifting capacity.
The box figure is called dimensional or volumetric weight, and the arithmetic is the same across the trade:
- 01Multiply length by width by height in centimetres
- 02Divide by a divisor the carrier publishes. 5000 is the convention in the courier, express and parcel trade
- 03The answer is in kilograms
A 40 by 30 by 20 cm box is 24,000 cubic centimetres, which divided by 5000 is 4.8 kg. If the scale says 3 kg, you are charged on 4.8 rounded up. 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.
Two rules that vary between carriers, and matter
Ask about both before you compare prices.
- The threshold. QCS applies dimensional weight only when the scale weight is 5 kg or less; above that the scale weight is used. Not every carrier has a threshold, and one without it applies the box rule at every weight
- The rounding step. QCS rounds up to the next half kilo, always up and never to the nearest. Carriers that round to the nearest kilo produce different figures from carriers that round up to the half
Two carriers with the same headline rate and different rounding rules do not charge the same price. Chargeable weight versus actual weight works a full example through.
Input two: the zone
Zones are how distance enters the price without the carrier having to measure distance. A city is split into bands, and an address falls into one of them.
Zone surcharges come in two shapes and the difference is large on a heavy parcel:
- Flat per parcel. Added once, regardless of weight. The Lahore extended area is this: a flat PKR 50
- Per unit. Added for every half kilo or kilo, so it compounds with weight
A carrier quoting a lower base rate with a per-unit zone surcharge can easily be more expensive than one quoting a higher base with a flat surcharge, and the crossover is somewhere in the middle of your weight range. Lahore delivery zones explained sets out how an address gets assigned, and the coverage map shows the boundary.
Input three: the service level
Same-day or express carries both a higher first unit and a higher step rate, not just a flat premium. In the QCS tariff standard is PKR 180 and PKR 40, express is PKR 250 and PKR 50. That means the premium grows with weight rather than staying constant.
Service levels also carry conditions, and the conditions are where sellers get caught. Express requires collection before 13:00. A service you cannot meet the condition for is not a service you have. Same-day versus standard in Lahore covers that trade.
Putting the three together
The structure is almost always a first unit plus a step, not a rate per kilo:
charge = base for the first unit + (units − 1) × step + zone surcharge
For a 2 kg standard parcel inside Lahore City: four half-kilo units, so PKR 180 + 3 × PKR 40 = PKR 300. To the extended area, PKR 350. As express, PKR 250 + 3 × PKR 50 = PKR 400.
What else can appear on a courier bill
Optional fees exist across the trade and you should ask which are active rather than assuming none are.
- A COD collection fee, flat or a percentage of the amount collected
- Declared-value insurance above a threshold
- A fuel adjustment, either folded into the quoted rate or added separately
- A weekend or holiday surcharge
- A reattempt fee after the first failed delivery
All five are inactive in the QCS tariff today, and the published rates are inclusive of sales tax and the fuel adjustment, so nothing is added at invoice. The point is not that nobody charges them; it is that "PKR 180" means different things depending on which of them a carrier has switched on.
Two questions that separate a good quote from a bad one
- 01Is the price frozen at booking against a dated rate card, or computed when the invoice is raised? A rate that can move after the work is done is not a rate, it is an estimate
- 02Is an undelivered parcel charged? At QCS it is not, and a parcel returned to you is not charged either, which the published tariff states as a term
If you are comparing carriers rather than understanding one, eleven questions to ask before you choose covers the rest.
Booking in Lahore starts at PKR 180 for the first 0.5 kg. Work out your own figure before you commit.
