priority mail postage cost

priority mail postage cost depends on package weight, size, destination, and whether you’re using flat-rate or custom boxes. USPS Priority Mail is known for its balance of speed and affordability, offering 1–3 day delivery for domestic shipments. Flat-rate options provide predictable pricing regardless of weight (up to 70 lbs), while zone-based pricing varies depending on shipping distance. The service includes tracking and insurance, making it ideal for small businesses and individuals. Using USPS’s online calculator or shipping software can help determine the exact cost based on your specific needs.
