What shipping protection should actually cost

Flat-rate protection overcharges small baskets and underprices large ones. Here is what the price should actually respond to.

Most shipping protection is sold at a flat percentage of cart value, or worse, a flat fee. Both are the same mistake in different clothing: a single price applied to orders with wildly different risk.

Why one price fails at both ends

On a small order, a flat fee is proportionally enormous. A shopper spending forty dollars is being asked to add something that feels like a meaningful percentage of what they came for, to protect against a risk they have probably never personally experienced. Opt-in collapses.

On a large order, the same fee is trivially cheap relative to the exposure. Which sounds like a win until you realize it means your protected volume is concentrated in exactly the orders most expensive to replace.

You end up with poor opt-in where the risk is low, and excellent opt-in where the risk is high. That is adverse selection, and it is a structural problem no amount of copywriting fixes.

What the price should respond to

  • Cart value. The obvious one, and the only one most apps use.
  • Destination. Loss and theft rates vary enormously by zip code. This is not a guess, it is in the carrier data.
  • Carrier and service level. A signature-required service and an unsigned drop have different outcomes.
  • Product category. Fragile goods fail differently from apparel.
  • Customer history. A returning customer with a clean record is a different proposition from a first order to a freight forwarder.
  • Season. December is not November.

Each of these is knowable at the moment of checkout. Using none of them, which is the industry default, means every shopper subsidises the riskiest orders in your book.

Who should be holding the pen

There is a second question underneath the price: who sets it. Handing the merchant a rate slider looks like control and is mostly a way of transferring the risk of getting it wrong. Price the offer too high and opt-in collapses. Too low and the pool cannot fund the claims it exists to cover, which the merchant then discovers later.

The provider carrying the claims is the party with the loss data, the carrier mix and the seasonal pattern to price against. It should also be the party that eats the mistake. What belongs to the merchant is the frame: a floor, a ceiling, which categories are excluded, and where the offer appears. Those are policy decisions. The number itself is an underwriting decision wearing a policy costume.

The line you should not cross

Pre-checked boxes lift opt-in immediately and reliably. They also produce chargebacks, one-star reviews and, increasingly, regulatory attention. Any vendor who offers you a pre-checked option is optimizing a number that is not the one you care about.

An offer that a customer would be annoyed to discover after the fact is not a pricing strategy. It is a liability with good short-term metrics.
