Worked Examples

Example 1: Sending a Postcard in the US

Let's say you're sending a postcard in the US using USPS. The postcard measures 4 inches by 6 inches and weighs 1 ounce. Using the USPS rates:

Postage Cost = $0.20 (Base Rate) + (1 × $0.15) + (1 × $0.05) = $0.40

The total cost for this postcard would be $0.40.

Example 2: Sending a Postcard in the UK

If you're sending a postcard in the UK using Royal Mail, the postcard measures 4 inches by 6 inches and weighs 10 grams. Using Royal Mail's rates:

Postage Cost = £0.15 (Base Rate) + (10 × £0.01) + (1 × £0.02) = £0.27

The total cost for this postcard would be £0.27.
