What is a good attach rate?

In wireless and electronics retail, a healthy accessory attach rate is often well above 100% — meaning more than one accessory per device (a case AND a screen protector AND a charger). Under 100% usually signals a big, easy margin opportunity: the traffic is already in the store buying the device, so every extra add-on is high-margin incremental revenue.

How to lift attach rate

•Bundle the obvious pairs — the case, protector and charger that go with each device.
•Show attach at the point of sale, not as an afterthought at checkout.
•Track attach per device and per store so you can coach the locations that lag.
