Formula

weightFee = perKgFee * Math.max(0, weightKg - freeKg); charge = baseFee + weightFee + distanceFee

How the calculation works

The calculator subtracts the free weight allowance from the parcel weight and keeps only the amount above the allowance.

It multiplies that extra weight by the per kilogram fee and adds the base fee to get the weight part of the charge.

The distance fee is then added so the total reflects both how heavy and how far the order has to travel.

Common mistakes

When to use it

Worked example

With a base fee of 60 taka, a free allowance of 1 kilogram, 20 taka per extra kilogram, a 3 kilogram parcel and a 30 taka distance fee, the weight fee is 40 taka and the delivery charge is 130 taka.

Charge ৳130.00
Weight fee ৳40.00
Distance fee ৳30.00

Common questions

What is the free weight allowance?

It is the weight included in the base fee, so a parcel up to that weight pays only the base fee and any weight above it pays extra.
