YETI Tundra 45 hard cooler
The Tundra 45 is a known quantity, so the estimate can be exact. A plain “cooler” spans lunchbox to marine chest and would be priced at the category's midpoint instead.
A hard 20–45 quart cooler boxes up around 22 × 16 × 16 inches at 8–18 lb. Rotomolded premium coolers are heavy and bulky at the same time, so both real and dimensional weight play into the price — measure the packed box, not the cooler. From there the cost is a function of your lane and your patience, and the only reliable way to learn it is a quote on your own ZIPs.
The example running through this page was rated for real: 28 × 18 × 17 in at 28 lb, $50.02 with UPS Ground on the Wisconsin-to-Carolina lane below.
The test case: “YETI Tundra 45 hard cooler”, entered in the SMKlog calculator on 2026-07-24 with Milwaukee, WI 53202 as origin and Charlotte, NC 28202 as destination. Every value below came back from that single request, published unedited, with the sizing done by the tool rather than a tape measure.

Milwaukee to Charlotte, quoted live on two functioning ZIPs. The distance between them is the single biggest input to these rates; everything else on the page is second-order by comparison.
A cooler is a box full of insulation, and the rates treat it that way: 28 × 18 × 17 ÷ 139 comes to about 61.6 lb dimensional, better than double the 28 lb actual weight, so volume is what gets invoiced below. A closer-fitting carton is the one lever that cuts this cost.
| Carrier | Service | Price | Estimated transit |
|---|---|---|---|
| UPS | Ground | $50.02 | 4-5 business days |
| FedEx | Smart Post | $67.85 | 4-5 business days |
| FedEx | Ground | $71.07 | 4-5 business days |
| UPS | Ground Saver | $71.67 | 6 business days |
Every amount above is a finished checkout total, carrier label and SMKlog's charge together, with no trailing fees. UPS Ground undercut the field here at $50.02. Consider the table a specimen rather than a promise: rates get retuned by the carriers regularly, and a different ZIP pair rewrites the whole column, so run yours before deciding anything.
About 22 × 16 × 16 in once boxed. Latch the lid shut, pack the inside with paper (free structural strength), and use a box with 2 inches of clearance. Drain plugs unscrew in transit — tape them and pack them inside the cooler.
8–18 lb packed. What the invoice reflects is the bigger of scale weight and the volume figure, and for coolers the volume figure nearly always rules, so the packed measurements are the numbers to obsess over.
Lane length, chosen speed, and packed bulk. Milwaukee to Charlotte covers serious ground, and across four services the same box priced from $50.02 to $71.67. A neighboring-state move undercuts that range; air blows through the top of it. The spread is the point: real quotes on real routes replace flat answers that don't exist.
Plan around 22 × 16 × 16 in packed. Latch the lid shut, pack the inside with paper (free structural strength), and use a box with 2 inches of clearance. Drain plugs unscrew in transit — tape them and pack them inside the cooler.
Typically 8–18 lb packed. Whichever comes out higher, the scale reading or length × width × height divided by the carrier's divisor, is what you're billed on, so check both on the sealed carton first. A hopeful underestimate just resurfaces later as an adjustment charge.
Yes — the box size stays the same, so soft contents ride almost free. Keep the total packed weight in mind: crossing 50 lb triggers a heavy-package surcharge that can double the price.
Non-perishable food is fine. Perishables need overnight-class speed and become a different, expensive problem — for a normal ground shipment, ship the cooler empty or with dry goods only.
Mostly bulk. A boxed cooler measures about 22x16x16 in but only 12 lb, and carriers bill the greater of actual and dimensional weight — this box computes to roughly 41 lb dimensional, over three times the scale weight. That volume, plus the zone it travels and ground versus expedited speed, sets the quote. Give the SMKlog calculator your cooler's details and ZIP pair and it compares USPS, UPS, and FedEx live.
Treat it as a dimensional-weight problem. At about 41 lb billable, UPS and FedEx ground usually price this class best; USPS applies dimensional pricing above one cubic foot, and a cooler box is roughly three times that. Choose a box that hugs the cooler — every inch of spare air is billed — and skip oversized cartons. Buying the label online at commercial rates typically runs 20-40% below walk-up counter prices.
