Shipping Estimate
Shipping cost is based on either actual weight or dimensional weight — whichever is greater.
Dimensional weight formula:
DIM Weight (lbs) = (Length × Width × Height) / DIM Factor
DIM factors:
- USPS: 166
- UPS/FedEx: 139
- International: 139–166
Example: A box 18×12×10 inches, weighing 5 lbs:
- DIM weight = (18 × 12 × 10) / 139 = 15.5 lbs
- Carrier uses 15.5 lbs (greater than actual 5 lbs)
Approximate US domestic rates (ground, 2024-2025):
| Weight | USPS Ground | UPS Ground | FedEx Ground |
|---|---|---|---|
| 1 lb | $5–8 | $8–12 | $8–12 |
| 5 lbs | $8–15 | $12–18 | $12–18 |
| 10 lbs | $12–22 | $15–25 | $15–25 |
| 20 lbs | $18–35 | $20–35 | $20–35 |
| 50 lbs | $30–60 | $30–55 | $30–55 |
Tips:
- Use the USPS flat-rate boxes when possible for heavy items
- Compare rates across carriers for best prices
- Shipping zones (distance) significantly affect price
