Your figures

Only couriers that are switched on appear here. Choose "enter a rate myself" to use a figure from your own contract.

Express and surface are priced differently by every courier.

Zones are each courier's own definition. The zone calculator works one out from a city or PIN code.

Where the rate comes from

Your own contract rate is always more accurate than a published tariff.

What your courier actually charges for a parcel like this.

The packaging cost calculator works this out from your bulk pack prices.

Payment

COD charges apply only where one has been configured.

The parcel

What the packed parcel weighs on a scale.

From your courier's rate card. 5000 and 4000 are both common, and the difference is 25% of the billed weight - so check rather than assume.

About this calculator

A batch quote is one parcel priced correctly and then multiplied. The mistake is doing it the other way round: taking the total weight of a batch, looking up one rate for it, and getting a number that bears no relation to what a courier will invoice for a hundred separate parcels.

This prices one representative parcel through the full rate engine — chargeable weight, rate band, surcharges — and then scales it across the batch, with packaging counted per parcel.

How to use this calculator

  1. Choose the courier, or "enter a rate myself" for a contract rate.
  2. Enter how many parcels are in the batch.
  3. Enter the average weight and, if the parcels are bulky, their dimensions.
  4. Add packaging per parcel.
  5. Read the batch total and the per-parcel figure it came from.

The formula

Chargeable weight = greater of actual and volumetric, per parcel
Cost per parcel   = base rate + surcharges, for that weight
Shipping total    = cost per parcel x parcels
Packaging total   = packaging per parcel x parcels
Batch total       = shipping total + packaging total

Every parcel is charged as its own shipment, because that is what it is. There is no bulk discount in this arithmetic — a negotiated volume rate belongs in the rate itself, entered as your contract rate.

Worked example

A batch of 100 parcels at a contract rate of ₹62 each with ₹18 of packaging:

Shipping   100 x 62 = 6,200
Packaging  100 x 18 = 1,800
Batch total         = 8,000, or 80 per parcel

Doubling the batch doubles the total. Where a courier has offered a better rate at volume, enter that rate rather than expecting the calculator to find it.

Notes and limits

  • This assumes the parcels are alike. An average weight across a batch of genuinely mixed parcels will land in the wrong rate band for most of them - price them in groups instead.
  • Averaging is particularly misleading near a band boundary. Fifty parcels at 0.9 kg and fifty at 1.6 kg do not cost what a hundred at 1.25 kg cost.
  • Volume discounts are a matter for your contract, not for the arithmetic. Enter the rate you negotiated.
  • A batch going to a single destination may qualify for a consignment rate instead, which is priced quite differently from a hundred individual parcels.

What this calculation assumes

  • All parcels in the batch are alike in weight and size.
  • Each parcel is billed as its own shipment, with no bulk discount applied by the calculator.
  • Packaging is charged per parcel.

Frequently asked questions

How do I work out shipping for a bulk order?

Price one representative parcel properly - chargeable weight, rate band, surcharges - and multiply. Do not add the weights together and look up a single rate, because each parcel is billed as its own shipment.

Do couriers give discounts for volume?

Yes, through contract rates rather than through the published tariff. If you ship consistent volume, it is worth asking - and the rate you agree is the one to enter here.

Can I use an average weight for mixed parcels?

Only where the parcels really are similar. With slab pricing, an average can put every parcel in a band none of them belongs to. Split the batch into weight groups and price each group.

Is it cheaper to send one heavy parcel or several light ones?

Usually one heavier parcel, because each parcel pays its own minimum charge, its own surcharges and its own packaging. Check against your own rate card - the per-kilogram rate normally falls as weight rises.
