Detailed Breakdown
Overnight shipping is where USPS and FedEx are most comparable in price, but they differ significantly in delivery windows and flexibility. USPS Priority Mail Express guarantees next-day delivery by 6 PM for most addresses and offers a money-back guarantee if it arrives late. FedEx Priority Overnight guarantees delivery by 10:30 AM to most business addresses, giving you a full extra half-day. FedEx also offers First Overnight (by 8 AM) and Standard Overnight (by 3 PM or 4:30 PM), giving you three tiers to choose from. The price difference is meaningful: USPS overnight for a 1 lb package runs $25-30 while FedEx starts at $27-45 depending on the service tier. If you just need something there the next day and do not care whether it arrives at 10 AM or 4 PM, USPS saves you money. If the package absolutely must be there by morning, FedEx is the more reliable option.
Frequently Asked Questions
Yes, USPS Priority Mail Express is typically $5-15 cheaper than FedEx Priority Overnight for the same package weight. However, USPS delivers by 6 PM while FedEx delivers by 10:30 AM. If morning delivery is not important, USPS offers good savings on overnight shipping.
Yes, USPS Priority Mail Express comes with a money-back guarantee. If your package is not delivered by the guaranteed time (next day by 6 PM for most areas, or 2 days for remote locations), you can request a full refund of postage. Some very remote areas are 2-day delivery rather than overnight.
FedEx generally has later cutoff times, with FedEx dropboxes accepting overnight packages until 7-8 PM in many areas. USPS post offices typically stop accepting Express Mail by 5 PM, though times vary by location. For the latest possible dropoff, FedEx Office locations and FedEx dropboxes usually offer the most flexibility.
USPS delivers Priority Mail Express on Saturdays at no extra charge -- it is part of the standard service. FedEx offers Saturday delivery but charges a surcharge that can add $16 or more to the shipping cost. If you need Saturday overnight delivery, USPS is the clear value winner.
