FAQ

Common questions about the quick phone guide

What does this quick phone guide include?

It includes the phone price through value loss, the carrier plan, accessories, device protection, repairs, and the default phone-specific service costs. It uses the same formulas as the full phone calculator.[1][2]

Why is the phone's full price not counted twice?

Because the guide tracks the part of the phone value you actually use up over time. Counting the full price and the full value loss together would double count the same money.[1][2]

When should I use the full phone calculator?

Use the full calculator if you want to change accessories, protection, repairs, phone-specific subscriptions, or the resale assumption in more detail.[1][2]
