When you need a package to arrive the very next day, overnight shipping is one of the best options. But you know that taking advantage of such offerings is going to cost you extra.
That’s life! But, there is some good news!
By being smart and utilizing this short guide, you can save money when sending packages and take advantage of the cheapest overnight shipping options available.
Cheapest overnight shipping considerations
Before we look at the cheapest overnight shipping options, it’s important to understand what factors impact shipping prices.
1. Package dimensions
Most overnight shipping companies use a pricing model called dimensional weight — also known as ‘DIM weight’ — to calculate shipping costs. DIM weight uses a parcel’s dimensions to determine how much it will cost to ship.
While it sounds complicated, the DIM weight is calculated by simply multiplying the package’s length, width, and height, then dividing that number by something called a ‘DIM divisor’. Shipping companies then determine shipping rates by choosing which is larger: the package’s actual weight or its DIM weight.
2. Package weight
The package weight is literally just how much it weighs (no calculations, divisors, nothing). If this is greater than the DIM weight, this will be what the shipping company uses to calculate the cost.
As a rule of thumb, the heavier the package, the more expensive it will be to ship (especially if you’re looking to send it overnight).
3. Destination
Shipping companies also use geographical zones to determine how much a package will cost to ship. Shipping zones range from Zone 1 to Zone 8 in the United States, and track the distance a package travels along its journey, from origin to destination.
Note: In some cases here is where you can really save money! If you recognize the zones, it can sometimes be better to send a flat rate package (regardless of weight) to a zone further away. For example, my wife sent Christmas gifts flat rate out west, but locally she sent gifts based on weight. The trick to this is friending the USPS worker at your local post office! 🙂
4. Value
When shipping high-value items, it is often necessary to secure insurance to protect against the package being damaged, lost or stolen. While this provides peace of mind, it also adds to the overall cost, so don’t be surprised if a package with high-value contents costs you more.
5. Service
Last but certainly not least is the type of service you choose to ship your package. For the purpose of this article, we’re focusing on the cheapest overnight shipping options (which are also among the most expensive services).
Remember: the longer you’re willing to wait for something to be delivered, the cheaper it’s going to be to ship.
The cheapest overnight shipping options: USPS vs. UPS vs. FedEx

The first thing to be aware of is that three of the biggest shipping carriers — USPS, UPS, and FedEx — all call their overnight shipping options something different.
- USPS's guaranteed overnight service is called Priority Mail Express
- UPS's guaranteed overnight service is called UPS Next Day Air
- FedEx's guaranteed overnight service is called FedEx Overnight (FedEx First Overnight for delivery the next morning)
So how do they all compare?
The answer is “it depends on what you’re shipping”.

Are overnight shipping options really guaranteed?
While shipping companies provide amazing services, they can’t perform miracles, and that means there is no 100% guarantee that your overnight package will always get to its destination the next day.
When you see the word “guaranteed”, it simply means the shipping company will usually refund your shipping costs if they don’t fulfill their promise. Always check the individual shipping company’s T’s & C’s to avoid disappointment.

As we’ve already mentioned, a lot of different factors determine a package’s shipping cost. Luckily, USPS, UPS, and Fedex all have their own shipping calculators to help you check costs at your leisure.
