How the Calculator Works
The calculator uses USPS pricing formulas to estimate shipping costs. Here's how it works:
First Class: Base rate + weight-based surcharge
Priority: Base rate + weight-based surcharge + dimensional weight surcharge
Parcel Select: Base rate + weight-based surcharge + dimensional weight surcharge
The calculator considers both actual weight and dimensional weight (length × width × height ÷ 139) to determine the final shipping cost.
Example Calculation
Let's calculate the cost of shipping a 2 lb (32 oz) package using Priority Mail:
- Select "Priority" from the service dropdown.
- Enter "32" in the weight field.
- Enter dimensions (e.g., 10" × 8" × 2").
- Click "Calculate".
The calculator will show the estimated cost based on USPS Priority Mail rates for your package size and weight.
