Delivery value
Do not multiply every order by an imaginary shipping fee. Estimate what you would realistically have paid, the trips you avoided, or the delivery speed you value. If you would simply wait for a free-shipping threshold elsewhere, enter a low delivery value in the calculator.
Entertainment value
Prime Video adds measurable value when it replaces another paid service or content purchase. It adds less when you keep all existing subscriptions and watch only occasionally. Included music, reading and gaming features should be evaluated the same way.
Deals and cash back
Count a discount only on a purchase you already planned to make. Limited-time categories, percentages and end dates can change, so verify the live offer before using it in a yearly estimate.
