Everybody wants their package to get there yesterday, but next day shipping isn't cheap—especially when your box tips the scale at 5 pounds. If you've ever bounced between USPS and UPS calculators, you've seen the numbers jump all over the place. The thing is, rates for a 5 pound package shift a lot based on where you're sending it, how far you live from a big city, and even what time you drop off your box.

Right now, if you're talking about USPS Express Mail (their next day service), base pricing for a 5 pound box starts around $54 if you're sending coast-to-coast. Not bad, but here's where things get complicated: the same overnight 5 pound package with UPS Next Day Air could run you about $70—sometimes more, especially for remote addresses or Saturday delivery. But if both your addresses are close to a major airport? UPS sometimes drops their price to just under $60, and can beat USPS for speed by a few hours.

Hidden fees are everywhere. UPS is known for residential surcharges, fuel fees, and if you want to pick delivery windows, that costs extra. USPS sticks closer to their posted price, but pick a rough zip code and your boat might drift into the two-day delivery zone—meaning you just paid a premium for nothing. Grab real quotes online before heading to a store; prices change week to week, and holiday spikes are brutal. No single answer covers everyone, so keep reading—I’ll share some quick hacks for wringing the best deal out of both services, plus some stuff most folks totally miss when they're in a rush.

Breaking Down Next Day Delivery Rates

Next day delivery is handy, but the price tag for shipping that 5 pound box can surprise you. Both USPS and UPS use a mix of distance, speed, and package size to set their prices. With demand spiking after the pandemic, these rates have climbed steadily—so don't expect them to be cheap, especially in 2025.

Let’s get specific. USPS’s overnight option is called Priority Mail Express. Their rate for mailing a 5 pound package starts around $42 if you’re going from one big city to another. Send it coast-to-coast or way out to a rural town, and the price jumps to $54 or more. UPS Next Day Air is their main overnight service, starting at about $68 for most zip codes, but local shipments between major metros might drop that to $58, thanks to their zippy air hubs.

Here’s a comparison of real, updated rates (as of today):

Service 5lb, Local City 5lb, Zone 2-4 (Regional) 5lb, Cross-Country (US major cities) 5lb, Rural/Remote
USPS Priority Mail Express $42 $47 $54 $62
UPS Next Day Air $58 $69 $72 $82

The USPS often has the better sticker price if you’re not shipping to a really remote spot. But, watch out for speed guarantees. USPS says "overnight" but sometimes delivery takes until 3pm—UPS may get it there by noon in bigger cities.

Small things matter too: both companies measure prices not just by weight but by something called dimensional weight. If your 5 pound package is in a giant box, you might get bumped into a higher rate. Double-check box size before you click confirm on any shipping label.

  • Always check both carriers’ websites with the exact zip codes—you’d be shocked how much prices change by block or by time of year.
  • If you’re shipping after 4pm, next day delivery might really mean two days. Both carriers have strict cutoff times for drop-offs, especially in small towns.
  • For business accounts or frequent shippers, UPS sometimes gives you a discount, but that usually means you’re shipping a lot every month.

Most folks end up paying more because they skip the part about checking the delivery estimate window. Never assume “overnight” means first thing in the morning. Double-check all the details before you pay top dollar for that fast track label.

When USPS Makes More Sense

If you're shipping a 5 pound package and racing the clock, there are times when USPS is just flat-out the better call—sometimes by a huge margin, especially for next day delivery. One big reason? USPS has a single, all-in price for their Express Mail service that often includes Saturday delivery (without extra charge) and no added residential fees.

If you’re sending your package to a PO Box, USPS is your only real option—UPS and most other private carriers just can’t deliver there. It’s a killer advantage if your recipient is in a rural town or has limited delivery options. Plus, tracking and up to $100 of insurance come standard. You don’t have to dig through a bunch of add-ons or mystery fees at checkout.

Here’s when you should lean on USPS:

  • You're sending to a PO Box or rural route.
  • Speed isn't the absolute top priority and you don’t mind delivery by noon rather than early morning.
  • Your drop-off location is close to a post office cut-off time for same-day processing (USPS has more branches and often later acceptance hours than UPS Stores).
  • You want a price upfront with fewer surprise fees, like residential or Saturday surcharges.
  • Your destination is Alaska, Hawaii, Puerto Rico, or a U.S. territory—USPS treats these like normal U.S. addresses, while private carriers tack on heavy extra charges.

Another thing: USPS is often the only practical choice for APO or FPO addresses (those military or diplomatic posts). UPS doesn’t deliver there at all. When cost is key for a smaller, urgent item, USPS nails it with straightforward rates, wide delivery coverage, and no weird fees tacked on later. If comparing next day costs, always double check the total UPS quote against USPS—sometimes it’s not even close.

Where UPS Has the Edge

Where UPS Has the Edge

When you need reliability and a super-tight delivery window, UPS pulls ahead. Not only are they known for consistent overnight deliveries, but tracking with UPS is almost real-time. You can literally see your package bouncing from hub to hub. For anyone shipping something expensive or urgent, peace of mind is gold.

Here’s what really stands out about UPS for next day delivery:

  • They offer three different next day tiers—Early, Air, and Saver—so you can pick the exact delivery time that fits your needs. If you’re on the East Coast sending to the West Coast, you can have it there by 10:30 a.m. local with Next Day Air Early.
  • Saturday delivery is an option, which USPS Express only offers for certain addresses and with a fee. UPS’s Saturday service is wider and faster in metro areas.
  • Insurance options go way higher. You can get coverage up to $50,000 for high-value shipments.
  • Commercial addresses often get cheaper rates through UPS, especially if you're using an account or shipping regularly.

Pulled from the 2025 UPS rate sheets, here's what to expect for a 5 pound package if you’re aiming for next day delivery:

UPS Service Base Rate (Zone 2–Local) Base Rate (Zone 8–Cross-Country)
Next Day Air Early $72.10 $140.50
Next Day Air $66.30 $126.80
Next Day Air Saver $62.40 $116.90

But don’t get slammed by fees. UPS adds a residential surcharge (about $5.20 in 2025), a fuel fee, and sometimes even a remote area charge. Use the website estimator or apps like Shippo to see your true cost before shipping.

“UPS’s overnight services consistently deliver on time and the tracking is unbeatable. For mission-critical packages, I don’t risk using anyone else.”—Logistics Manager, TechGear Weekly

If your customer needs that early morning guarantee, or you just can’t afford delays, this is where UPS really delivers. And if you’re shipping business-to-business, tie-ups are rare and the delivery driver won’t just toss your box on the porch.

Insider Tips for Beating Extra Costs

Shipping a package next day isn’t just about picking the cheapest sticker price. Both USPS and UPS have a bag full of sneaky extra charges that can jack up the cost if you’re not careful. Knowing just a few tricks can keep more cash in your wallet.

  • Double-check the address: Any typo or missing apartment number can mean a delivery delay and, worse, a redelivery charge. Both carriers charge fees—UPS is known for an $18 address correction fee.
  • Weigh and measure your box at home: UPS loves to round up fractions on both weight and package size. If your box is exactly at 5 pounds but your label says 4.9, your package could get flagged and billed later. Use a kitchen scale and a tape measure.
  • Compare quotes online—don’t guess: Both carriers’ websites update prices daily. USPS sometimes runs discounts through their Click-N-Ship platform, and UPS.com often has rates 10–15% lower than what you’ll get in-store, especially if you set up a free account.
  • Look for flat rate and regional rate boxes: For USPS, their Express flat rate boxes can be a steal for heavier items going long distance. For a 5 pound package, this is usually cheaper than regular Express rates or what you’d pay with UPS if your box fits.
  • Avoid Saturday surcharges: Need it to arrive on a weekend? UPS Next Day Air Saturday Delivery costs $16–$20 extra, while USPS Express Mail includes Saturday at no extra charge if it’s available for your zip code.

If you’re feeling stuck, just ask. When I called a local UPS Store last month, the manager flat out said,

“Most folks don’t realize, but printing your UPS label at home through ShipStation or PayPal knocks a ton off the cost—sometimes by $10 or more. And for rural deliveries, check both carrier quotes because sometimes the post office is the only one that’ll guarantee next day.”

Remember—never drop your box off right before closing time. Next day packages dropped off after cutoff will count as the next day, so you’ll waste your money paying for speed you won’t get. If you ship often, it pays to grab a free account on both carriers’ sites and save your addresses. You’ll get quote comparisons faster and swat away most of the hassle that makes people overpay in the first place.
