4 Crucial Shipping Rate Factors to Consider

No singular, universal shipping method is considered the gold standard for inexpensively shipping a package. Keep in mind that depending on what you’re shipping you must also factor in a parcel’s weight and size, how quickly you need your package to get to its destination, and your shipping zone or country.

Here, we discuss the four crucial factors to consider when determining the best way to reduce shipping costs:

1. Speed

How fast do you want your package to get to its destination? As instant gratification becomes the norm, speedy shipping will certainly play a role. But keep in mind, the faster the delivery speed, the more you will have to pay.

Do you want your package to be delivered overnight, the next day, in two days, within three days, or you are willing to wait for 7days? Different courier companies offer various time-sensitive delivery options to cater to your preferred delivery timeframe. But you’ll have to pay to play, so to speak. Overnight delivery may cost five times more than ground delivery.

For 2-3-day shipping, USPS Priority Mail offers the most competitive rates for packages weighing 10lb and below. But UPS and FedEx services offer more enticing rates when shipping packages above 10lbs within the same delivery window.

For packages with a hard two-day delivery timeframe, UPS 2nd Day and FedEx 2Day are the best options because USPS doesn't offer guaranteed services within this timeframe.

For expedited next-day Day or overnight delivery, UPS Next Day Air Saver and FedEx Standard Overnight offer competitive rates compared to USPS.

2. Distance

First thing’s first, consider which shipping zone your package is being sent from. Shipping carriers split the US into 8 shipping zones based on the distance your package has to travel from the mailing address or zip code. The further the shipping zone from the destination address, the higher the shipping rate will be.

Domestic shipping vs international shipping also comes to play when sending packages to your customers in different places. As you would expect, international shipping comes at higher shipping rates than domestic shipping.

Having distribution centers in different parts of the US can help your business mitigate the shipping costs and shorten the delivery time for your customers by ensuring your merchandise is stored closer to the final destination. With that in mind, Easyship partners with 3PL providers and warehouses across different cities around the world to help you shorten your shipping distances and times.

3. Weight

The weight of your package is a crucial factor to consider when finding the cheapest way to ship boxes. How heavy or light your package is will impact its shipping rate.

USPS offers the most competitive rates when shipping lightweight packages under 1 pound or 16 oz, using USPS First Class Mail or USPS Media Mail when shipping physical media.

USPS Priority Mail offers a cost-effective option when sending items between 1-10 lbs, while FedEx and UPS Ground/Home delivery offer the lowest rates for heavy packages within the US.

4. Size

The size of a package has everything to do with how much space it occupies in the back of a track based on its dimensions. The larger the package, the greater the shipping cost. Different couriers offer several options to help you optimize your package size for shipping.

One such option is to use Flat Rate Packages with USPS. Although this isn’t always guaranteed to be the cheapest way to ship a box, it will help you maintain steady shipping costs. First Class Mail envelopes, flat rate envelopes, and USPS Priority Mail offer the lowest rates for small packages.

Another option is to use cubic pricing. Cubic pricing is a special USPS service that offers lower shipping rates when sending small, heavy items that are under 20lbs with USPS Priority Mail.

Here is how to calculate the cubic feet for your package:

Cubic feet = Length x Width x Height/ 1728

Dimensional pricing is also used when determining the shipping cost of your package. If your package is too large in proportion to its weight, the dimensional weight will be used to determine the shipping rate. The larger the dimensional weight, the higher the shipping rate, as the package will take up more space in airplanes and other cargo vehicles.

Dimensional weight is calculated by dividing the dimension of your package by a divisor. The larger the divisor, the cheaper the shipping rate.

Dimensional weight = (L x W x H)/ Divisor

USPS has the largest dimensional weight divisor, hence offering the cheapest way to ship a package based on its dimensional weight.

Additional factors to consider

There are also other additional factors that you need to consider — apart from the cost. A cheap option that doesn't offer excellent tracking services, insurance, or doesn't commit to its delivery timeframes may come with its share of inconveniences that outweigh the eye-catching price.

Here are some additional factors you should consider:

  • Insurance: Insurance provides security for your goods in transit. Plus, it helps to mitigate any risks related to lost or damaged packages. While researching how best to reduce shipping costs, it is smart to check whether the carrier with the most competitive rates offers insurance for your packages. While it may cost extra, it could make sense to go for a carrier with a higher shipping rate that includes insurance cover a cheaper option that doesn't cover you, and requires a separate purchase of insurance.
  • Tracking: Tracking helps you streamline your buyers’ shipping experience and it builds trust by providing package visibility throughout its journey. The most inexpensive way to ship a package may come with spotty tracking services, so you may need to weigh your options right to make sure that you select an option with excellent tracking services.
  • Handling Fees: Handling fees sometimes are applied depending on how delicate your shipment is. When choosing the cheapest way to ship boxes, you should always check to see whether you will need to pay any separate handling fees.
  • Fuel and residential surcharges: Often, inexpensive shipping plans have hidden costs — like last-mile delivery fees, like fuel or residential surcharges. When making your shipping choice, make sure to check for these additional charges.
  • Delivery guarantee: You need to check whether the cheapest shipping option commits to its delivery timelines so that you don't inconvenience your customers. After all, it’s always about serving your customers.

When Shipping Discounts Apply

Getting shipping discounts from courier companies can be a game-changer for your eCommerce business, as they can help you reduce your shipping cost per package. Shipping carriers will discount your rates depending on the volume of packages you send. The more you shop, the better your rates become.

Another great way to get discounted shipping rates is to access the major carriers through a 3PL company like Easyship. You'll always get better rates when using the services of a third-party courier as compared to trying to negotiate directly with the courier companies.

3PL companies tend to get huge shipping discounts because of the large number of packages they send to these couriers. Then, they pass down the benefits to their partners by offering them discounted rates. It’s a win-win.
