What USPS, FedEx and UPS Charge for a 5 lb Package#

For a 5 lb package, USPS Ground Advantage is typically the cheapest option, from $7.24 in the app on the nearest zone (farther and rural destinations can price higher). On the farthest zone the app price is $15.02, still below the UPS Ground and FedEx Ground figures in the table there. Here's how all major carriers and services compare.

Packing a 5 lb Package Without a Dimensional-Weight Charge#

USPS, divisor 139, applied over 1,728 cu in

Not over one cubic foot, so it bills its 5 lb scale weight.

1,008 cu in is not over 1,728 cu in, so USPS bills the scale weight.

Try your own box

1. 1

   A 14 x 12 x 6 inch box (1,008 cubic inches) fits most 5 lb shipments and stays under the one-cubic-foot line, so USPS bills it on actual weight, not dimensions.

2. 2

   USPS applies dimensional weight to Ground Advantage and Priority only once a box exceeds one cubic foot (1,728 cubic inches), then divides length x width x height by 139 (lowered from 166 on July 12, 2026, matching UPS and FedEx). At 5 lbs that mostly matters for bulky-but-light items like pillows or foam, not dense goods.

3. 3

   The Medium Flat Rate Box, $25.80 at the Post Office, ignores both weight and zone, but at 5 lb that is a bargain only on the far zones: weight-based Priority stays under it through Zone 5 ($19.08 in the app against a $20.28 box), so on near and middle lanes the flat box makes you subsidize distance you are not shipping.

4. 4

   Keep the longest side under 22 inches and no dimension near 30 inches. Balloon and oversize surcharges start on large light parcels well before you hit a weight problem, and they can erase the whole 5 lb advantage.

5. 5

   Use double-wall corrugated for anything fragile at this weight. A 5 lb item generates enough momentum in transit that single-wall board flexes and invites damage claims.

Money left on the table

Where 5 lb Shippers Leave Money on the Table#

• Price a 5 lb order against its actual destination zone, not a generic quote. The same commercial label is $10.35 to a neighbor and $20.24 across the country, so a 'cheap at 5 lb' habit built on local tests breaks on distant orders.
• The Medium Flat Rate Box is $25.80 at the Post Office at USPS holiday prices ($20.28 in the app). At 5 lb weight-based Priority Mail runs $10.24 to $19.08 in the app through Zone 5, under the box, and $23.35 to $25.86 on Zones 6 to 8, over it. So default to weight-based Priority when you need 2-3 day speed on Zones 1 to 5, and quote the flat box on Zones 6 to 8.
• If you do not need 2-3 day speed, Ground Advantage undercuts weight-based Priority and the Medium Flat Rate Box at every zone. Only reach past it when a delivery deadline actually forces the upgrade.
• Through I'd Ship That a 5 lb Ground Advantage label starts from $7.24 on short zones, below both the commercial and retail counter prices, with the full price shown before you buy. That floor sits just $1.05 above a 1 lb label on the nearest zone in the app, so rate-shop rather than assume heavier always costs much more. Rural destinations price higher, so treat it as a floor, not a flat everywhere-rate.
• When a batch spans many zones, Ship Intelligence prices each order across USPS and UPS and locks the cheapest valid rate automatically, so the zone math happens on every label instead of only the ones you remember to check.

Shipping a 5 lb Package: Key Takeaways#

• At 5 lb, zone is the price. The same USPS Ground Advantage label roughly doubles from $10.35 in Zone 1 to $20.24 in Zone 8 at USPS commercial rates.
• At 5 lb, weight-based Priority beats the Medium Flat Rate Box ($20.28 in the app, $25.80 at the Post Office) on Zones 1 to 5, and the flat box wins on Zones 6 to 8, where weight-based Priority runs $23.35 to $25.86 in the app.
• Ground Advantage beats Priority Mail and the Medium Flat Rate Box at every zone when you do not need 2-3 day speed, so only upgrade for a real deadline.
• USPS beats UPS at 5 lb in every zone, but on published rates UPS Ground drops below Ground Advantage at every zone from 30 lb to 50 lb, and past 50 lb only on the far zones, so re-check both as weight climbs.
• The 2026 increases raised every number and shifted the flat-rate crossover slightly, so run live quotes instead of trusting last year's defaults.

What a 5 lb USPS Ground Advantage Label Costs by Zone#

At light weights the difference between zones is a dollar or two and easy to ignore. At 5 lbs it is the whole story: USPS Ground Advantage roughly doubles from the near end of the map to the far end, so the same product can be a $10.35 label or a $20.24 one depending only on where the buyer lives.

That is why a single 'what does 5 lb cost' number is misleading. Price against the real destination zone every time, and know the ladder well enough to sanity-check a quote before you print it.

Those figures are the USPS commercial ladder, not a fixed price. Through I'd Ship That the same 5 lb label starts lower, from $7.24 on a short zone, but the zone shape still holds, so the far end of the map always costs more than the near end.

• Zone 1-2 (same metro, under ~150 miles): $10.35 to $10.41 on Ground Advantage commercial.
• Zone 4 (~300 to 600 miles): $11.67.
• Zone 5 (~600 to 1,000 miles): $14.53 on Ground Advantage commercial.
• Zone 8 (1,800+ miles, coast to coast): $20.24, nearly double the Zone 1 price for the identical box.
• Sanity check any quote against this ladder: a $20 label to a neighboring state or a $10 label across the country usually means a wrong zone or a dimensional surcharge slipped in.

When the $25.80 Flat Rate Box Wins at 5 lb#

The Medium Flat Rate Box is $25.80 at the Post Office to any address, weight and zone ignored up to 70 lbs. Sellers hear 'flat rate saves money' and reach for it on everything, but at 5 lb that reflex overpays on the near and middle zones, because weight-based pricing stays lower there. The box earns its price on Zones 6 to 8.

Priority Mail by weight at 5 lb against the Medium Flat Rate Box, in the app

Priority Mail by weight is cheaper at zones 1 to 5; the box at zones 6 to 8. Both are Pro prices.

$10 $20 $30 Medium Flat Rate Box $20.28

Zone, $	1	2	3	4	5	6	7	8
Priority Mail, 5 lb, Pro price	10.24	10.44	11.54	13.94	19.08	23.35	25.78	25.86
Medium Flat Rate Box, Pro price	20.28 at every zone

Over the box: the Medium Flat Rate Box is cheaper at this zone

The honest comparison at 5 lbs is against weight-based Priority Mail, since both give you 2-3 day service. At USPS commercial rates weight-based Priority runs $12.04 to $16.37 through Zone 4, under the box's $22.02 commercial price, then $23.27 at Zone 5 and $28.10 to $30.93 on Zones 6 to 8, over it, so on commercial against commercial the box already wins at Zone 5.

In the app it runs $10.24 to $19.08 through Zone 5, under the app's $20.28 Medium Flat Rate Box, and $23.35 to $25.86 on Zones 6 to 8, where the box wins. So in the app at 5 lb weight-based Priority is the default 2-3 day choice on Zones 1 to 5, and the flat box earns its place on Zones 6 to 8.

• Zone 1-4: weight-based Priority ($10.24 to $13.94 in the app, $12.04 to $16.37 at USPS commercial) is far under the flat box. Skip the flat rate here.
• Zone 5: weight-based Priority runs $19.08 in the app, still under the $20.28 Medium Flat Rate Box. By Zone 6 it is $23.35 and the flat box is cheaper.
• Zone 7-8: weight-based Priority runs $25.78 to $25.86 in the app ($30.85 to $30.93 at USPS commercial), over the flat box, so the Medium Flat Rate Box takes the coast-to-coast lanes.
• If you do not need 2-3 day speed at all, Ground Advantage undercuts both the flat box and weight-based Priority at every zone. Only enter this comparison when speed is a genuine requirement.

Making the 5 lb Zone Call on Every Order, Not Just Spot Checks#

The zone ladder and the flat-rate crossover are simple to apply on one order. Across a day of orders spanning a dozen zones, applying them by hand is where the overpay creeps back in: a distant order gets the local default, a near order gets a flat box it did not need, and each slip is a few dollars.

The Workbench handles this at batch scale: import your orders, and each one is priced against its own destination across USPS and UPS in a single pass, then batch-printed. Ship Intelligence locks the cheapest valid rate per order and logs the savings analytics, so the zone-correct choice is the default on every label, not a decision that depends on someone remembering the crossover.

• Import the full batch so every order carries its real destination zone instead of a single assumed rate.
• Let Ship Intelligence pick the cheapest valid USPS or UPS rate per order, applying the zone and flat-rate math automatically.
• Batch-print the run, then reconcile against the analytics view to confirm the zone-correct service actually won on each label.

Common Mistakes When Shipping a 5 lb Package#

5 lb Shipping Checklist#

• Write down the 5 lb Ground Advantage zone ladder ($10.35 near, $14.53 at Zone 5, $20.24 at Zone 8, USPS commercial) and post it where packers can see it.
• Set the flat-rate rule: default to weight-based Priority for 2-3 day service at 5 lb on Zones 1 to 5, quote the $25.80 Medium Flat Rate Box on Zones 6 to 8, and use Ground Advantage when speed is not required.
• Capture real packed dimensions for your common 5 lb boxes and confirm they stay under one cubic foot to avoid dimensional pricing.
• Quote your two or three busiest lanes at their real zones and lock in the default service each deserves.
• Re-run those lanes after any 2026 carrier change, since USPS holiday pricing put the Medium box at $25.80 and reshaped these comparisons.
• Print a test 5 lb Ground Advantage label to your farthest common destination and compare it against what you pay today.
• Review claims and late deliveries monthly and adjust the default on any lane that keeps missing.

5 lb Shipping: Questions People Ask#

How much does it cost to ship a 5 lb package?

It depends far more on zone than on the extra pounds. At USPS commercial pricing, Ground Advantage runs $10.35 to $10.41 in Zone 1-2, $14.53 at Zone 5, and $20.24 in Zone 8. UPS Ground's published daily rate sits at $14.19 to $21.72 and the FedEx Ground list rate at $14.06 to $21.69 across zones 2 to 8, for similar delivery windows. Through I'd Ship That the same 5 lb label starts from $7.24 on short zones, below retail, with the full price shown for the exact destination before you buy.

What is the cheapest way to ship a 5 lb package?

USPS Ground Advantage. Through I'd Ship That it starts from $7.24 on short zones and stays below Priority Mail, the Medium Flat Rate Box and UPS or FedEx Ground at 5 lbs in every zone, though the number climbs with distance. If you need 2-3 day speed, weight-based Priority Mail is the better buy at 5 lb on Zones 1 to 5: in the app it runs $10.24 to $19.08 there, under the $20.28 Medium Flat Rate Box. On Zones 6 to 8 it climbs to $23.35 to $25.86 in the app ($28.10 to $30.93 at USPS commercial rates), so the flat box wins the far lanes. Your account is free to start and a label prints in about 30 seconds.

Does the Medium Flat Rate Box beat Priority Mail for 5 lbs?

Only on the far zones. The box is $25.80 at the Post Office at USPS holiday prices ($22.02 at USPS commercial rates, $20.28 in the app). Weight-based Priority Mail at 5 lbs runs $12.04 to $16.37 through Zone 4 at USPS commercial rates and $10.24 to $13.94 in the app, well under the box, and in the app it stays under the box through Zone 5 ($19.08). On Zones 6 to 8 it runs $23.35 to $25.86 in the app and $28.10 to $30.93 at USPS commercial rates, so there the flat box is the cheaper 2-3 day choice. The rule: use weight-based Priority for 2-3 day service at 5 lb on Zones 1 to 5, and quote the Medium Flat Rate Box on Zones 6 to 8.

Is it cheaper to ship 5 lbs USPS or UPS?

USPS Ground Advantage is cheaper at 5 lbs in every zone: $10.35 to $20.24 commercial versus $14.19 to $21.72 on the UPS Ground published daily rate, with a gap of $3.78 at zone 2, the widest at zone 4 ($5.48), and the narrowest coast to coast ($1.48 at zone 8). On published rates UPS Ground stays above Ground Advantage at 5 lb, undercuts it on single zones at 10, 15 and 20 lb, and is below it at every zone from 30 lb to 50 lb (past 50 lb the UPS handling charge hands the near zones back to USPS), which is why it is worth re-checking both carriers per order rather than assuming the 5 lb answer holds at heavier tiers.

Did the 2026 rate increases change the cheapest 5 lb option?

No, the ranking held: USPS Ground Advantage stays cheapest at 5 lbs. The increases from late December 2025 through January 2026 (USPS about +6.6% to +7.8%, UPS and FedEx about +5.9%) lifted every label, so what moved is the dollar gap, and with USPS holiday pricing putting the Medium Flat Rate Box at $25.80 the weight-based Priority option is now cheaper at 5 lb on more of the map than before, through Zone 5 in the app. Re-quote your two or three busiest lanes so your defaults reflect the current numbers, not last year's.

Is USPS or FedEx cheaper for a 5 lb package?

USPS is cheaper for a 5 lb package at every zone on published rates. USPS Ground Advantage runs $10.35 to $20.24 commercial by zone, while the FedEx Ground list rate runs $14.06 to $21.69 and the UPS Ground published daily rate $14.19 to $21.72 across zones 2 to 8. The gap is widest on near zones and narrows coast to coast, which is why a 5 lb parcel is worth re-quoting on far lanes rather than defaulting to one carrier for every order. FedEx appears here for comparison only; I'd Ship That prints USPS and UPS labels, not FedEx.
