Cheapest Way to Ship a Package in 2026

Updated for 2026 carrier rates. Find the lowest cost option for your next shipment.

Shipping costs eat into profits fast — whether you sell on eBay, Etsy, or your own store. The cheapest carrier depends on your package weight, dimensions, and destination. Here's how to find the lowest rate every time.

USPS: Best for Lightweight Packages Under 1 lb

USPS Ground Advantage starts around $4–$5 for packages under one pound and remains the most affordable option for lightweight shipments. First-Class Package is unbeatable for items under 13 oz. For heavier items, USPS Priority Mail Flat Rate boxes offer predictable pricing regardless of weight — the Small Flat Rate Box ships for around $10 anywhere in the U.S.

Under 1 lb: USPS Ground Advantage or First-Class Package ($4–$6)
1–5 lbs: USPS Priority Mail or Small Flat Rate Box (~$10)
5–20 lbs: Medium Flat Rate Box (~$16) beats zone-based pricing for heavy items

UPS: Best for Heavy Packages Over 10 lbs

UPS Ground becomes competitive for heavier shipments, especially when you ship with negotiated or third-party discounted rates. UPS Simple Rate boxes work similarly to USPS Flat Rate but with faster transit times for certain zones. For packages over 10 lbs shipping across multiple zones, UPS often undercuts USPS Priority Mail.

FedEx: Best for Time-Sensitive and Business Shipments

FedEx Ground and FedEx Home Delivery compete directly with UPS Ground on pricing for mid-weight packages. FedEx One Rate (their flat-rate option) is worth comparing against USPS Flat Rate for packages between 1–50 lbs. FedEx SmartPost (now Ground Economy) is often the cheapest option for low-priority, lightweight e-commerce shipments.

How to Get Discounted Rates

You almost never need to pay retail shipping rates. Here are the best ways to save:

Pirate Ship: Free account, no markup. Access USPS Commercial Plus and UPS rates that are 20–50% below retail. No monthly fees or minimums.
USPS Commercial Pricing: Available through most shipping platforms. Saves $1–$3 per package compared to counter rates.
Cubic pricing: If your package is under 20 lbs, USPS Cubic pricing charges by volume instead of weight — ideal for small, heavy items like books or candles.
Free supplies: USPS Priority Mail and Flat Rate boxes are free. Order them at usps.com/supplies.

Money-Saving Tips

Right-size your box. Dimensional weight pricing means oversized boxes cost more. Use the smallest box that fits your item with adequate padding.
Use Flat Rate when it makes sense. A 15 lb item in a USPS Medium Flat Rate Box costs ~$16 regardless of zone — the same item zone-priced could cost $25+.
Compare every time. No single carrier is always cheapest. Check rates for each shipment based on weight, size, and destination.
Ship from home. Avoid post office counter surcharges by printing labels at home and scheduling pickups.

Once you've chosen the cheapest rate, create your shipping label with ShippingLabel in under 60 seconds. For carrier-specific label formats, check our guides for USPS, UPS, and FedEx labels.
