About These Carrier Rate Calculators
These tools help you compare and estimate shipping costs across UPS, FedEx, USPS, and DHL. Live rate data is fetched daily from carrier APIs and served via our rate pipeline. Rates shown are estimates based on a Chicago origin ZIP - your actual rates will vary based on your origin, negotiated discounts, and applicable surcharges. Always verify final costs with your carrier.
UPS and FedEx pricing is nearly identical at retail rates, but the differences emerge in surcharges. FedEx Home Delivery covers residential stops at a slightly lower surcharge than UPS residential delivery, which can matter at scale. USPS has no residential surcharge at all, making it the go-to choice for lightweight residential packages - especially under 1 lb where First Class Package rates are hard to beat.
For packages over 1 lb going to residential addresses, compare all three carriers using actual weight and zone. UPS SurePost and FedEx Ground Economy (formerly SmartPost) are hybrid services that hand off to USPS for last-mile delivery and can save 20-30% for lighter packages. DHL is typically most competitive for international shipments under 10 lbs.
Rates are estimates based on published retail pricing. Negotiated account rates and applicable surcharges will change your actual cost. Always verify with your carrier before finalizing.
