1. What is USPS Postage Cost Calculation?

The USPS postage cost calculation determines the shipping cost based on the zone rate (distance) and package weight. This is fundamental for determining shipping expenses for packages sent via USPS.

2. How Does the Calculator Work?

The calculator uses the USPS postage formula:

Where:

• \( Zone\ Rate \) — Cost per pound based on shipping distance zone (USD/lb)
• \( Weight \) — Package weight in pounds (lbs)

Explanation: The total cost is simply the product of the zone rate (cost per pound) and the package weight.

3. Importance of Accurate Postage Calculation

Details: Accurate postage calculation ensures you pay the correct shipping fees and avoid delays or returns due to insufficient postage.

4. Using the Calculator

Tips: Enter the zone rate in USD per pound and the package weight in pounds. Both values must be positive numbers.
