7 Best Checked Bag Fee Calculators in 2026 (Free & Tested)

Every major US airline raised checked bag fees in 2026. American, Delta, United, and JetBlue all moved to $45 for the first bag. Southwest killed its longstanding free checked bag policy. If you’re booking a flight and trying to figure out whether it’s cheaper to check a bag on Alaska or just pay the carry-on fee on Frontier, you need a calculator that actually compares these numbers side by side.

I tested seven free checked bag fee calculators to find out which ones are accurate, which ones cover enough airlines to be useful, and which ones save you time versus just checking the airline’s site directly. The short answer: the best free checked bag fee calculator in 2026 is our own Checked Bag Fees tool because it covers 75+ airlines, includes overweight and oversize surcharges most other tools skip, and works as a standalone comparison without forcing you into a booking flow. Full disclosure: it’s our tool, so I’m biased. I’ve ranked it honestly against everything else I found, and I’ll point out where competitors do things we don’t.

What We Looked For

The point of a baggage fee calculator is saving you money before you book, not after. Here’s what mattered in testing:

• Airline coverage, because a tool that only knows about six US carriers is useless if you’re flying Ryanair or Turkish Airlines
• Fee accuracy and freshness, since every tool that hasn’t updated for the April 2026 hikes is showing you wrong numbers
• Overweight and oversize surcharges, the fees that blindside people at the check-in counter ($100 to $200 per bag on most airlines)
• Standalone usability, meaning you can compare fees without starting a booking or entering flight details
• Free with no signup, because paying to look up a $45 fee defeats the purpose

1. Vientapps Checked Bag Fees

Checked Bag Fees is a free, standalone fee comparison tool covering 75+ airlines. You get a sortable table with first bag, second bag, international, overweight (51-70 lb and 71-100 lb), and oversize (63-80 in) fees for every airline. There’s also a trip calculator that estimates your total for one to three bags on a domestic or international round trip.

• Shows overweight and oversize surcharges that most other tools skip entirely
• Every fee is cited to the airline’s official policy page with a “last verified” date

2. Google Flights Bags Filter

Google Flights includes a bags filter that adds estimated checked bag fees to displayed flight prices. Select how many carry-on and checked bags you’re bringing, and the listed price for each result adjusts to reflect estimated luggage costs.

Pros:

• Covers every airline in Google’s search results, which is nearly all of them globally
• Integrated into the flight search you’re already doing, no extra tab needed
• Effectively filters out Basic Economy fares when you need a carry-on, since those fares strip overhead bin access
• Free, no account required for basic searches

Cons:

• Not standalone: you can’t compare bag fees without running a flight search first
• Shows an estimated total, not a line-item breakdown of what the bag fee actually is
• Doesn’t account for elite status or co-branded credit card perks
• Fee accuracy depends on airline data feeds, which sometimes lag behind recent policy changes

Pricing: Free. Platforms: Web, iOS (Google app), Android (Google app) Best for: Travelers already searching for flights on Google who want total-cost comparison without opening a second tool.

3. KAYAK Baggage Fee Assistant

KAYAK offers two related features: a static Airline Fees directory where you can look up baggage, meal, and seat fees by carrier, and a Baggage Fee Assistant that overlays estimated bag costs on KAYAK flight search results.

Pros:

• Airline Fees directory covers hundreds of carriers globally with a searchable interface
• Baggage Fee Assistant updates listed fares to include bag costs during flight search
• Covers more fee types than most tools (meals, seats, unaccompanied minors, not just bags)
• Free, no account needed for either feature

Cons:

• The Airline Fees directory is static reference data, not an interactive calculator
• The Baggage Fee Assistant only works inside KAYAK’s flight search flow
• Fee estimates may not reflect edge cases (elite tiers, credit card benefits, route-specific pricing)
• No overweight or oversize surcharge data that I could find

Pricing: Free. Platforms: Web, iOS, Android Best for: KAYAK users who want bag fees factored into their existing search workflow, or anyone who wants a quick airline-specific fee lookup.

4. iFlyBags

iFlyBags by Farelogix is the most comprehensive standalone baggage calculator by raw airline count. It covers 300+ airlines using ATPCO (Airline Tariff Publishing Company) industry-standard data. You enter your itinerary, number of bags, weight, frequent flyer tier, and credit card, and it calculates optimal bag allocation across travelers.

Pros:

• 300+ airlines, the largest coverage of any standalone tool I found
• ATPCO data feed means fees update from the same source airlines use internally
• Handles specialty items that no other tool touches: golf clubs, scuba gear, guitars, surfboards, oversized luggage
• Factors in frequent flyer status and credit card benefits, which is rare

Cons:

• The interface looks like it was built in 2012, because it was
• SSL certificate errors appeared during my testing, which may indicate maintenance gaps
• Requires more inputs than simpler tools (full itinerary details, not just airline selection)
• Hard to tell how current the front end is despite the automated data feed

Pricing: Free. Platforms: Web Best for: Travelers with specialty luggage (sports equipment, musical instruments) or complex multi-carrier itineraries where bag fee allocation matters.

5. United Airlines Checked Bag Fee Calculator

United’s calculator is the best airline-native baggage fee tool I found. You enter your route, fare class, and MileagePlus status, and it returns the exact fee you’ll pay. No estimates, no approximations.

Pros:

• Returns your actual fee, not an estimate, because it knows your exact fare and status
• Accounts for MileagePlus elite status, United credit cards, and Star Alliance partner benefits
• Route-specific pricing for international flights where fees vary by destination
• Official United tool, so the data is always current by definition

Cons:

• Only covers United flights
• Useless for comparing across airlines, which is the whole point of shopping for the cheapest option
• Sometimes slow to load or times out entirely
• Requires you to enter route and fare details instead of just showing a number

Pricing: Free. Platforms: Web Best for: United flyers who want to know their exact fee after factoring in status and credit card benefits.

6. TravelClosely Luggage Fee Calculator

TravelClosely’s calculator is a newer indie tool where you select an airline, choose domestic or international, pick your cabin class, and enter the number and weight of your bags. It calculates the estimated fee and flags potential overweight charges.

Pros:

• Clean, modern interface that’s easy to navigate
• Weight-based inputs catch overweight fees before you arrive at the airport
• Also offers related tools on the same site (carry-on size checker, personal item checker, volume calculator)
• Free, no signup required

Cons:

• Limited airline coverage compared to the top picks, with airlines being added over time
• Originally published in mid-2025, and I could not verify how frequently the fee data is refreshed
• Gives estimates only, with a disclaimer that fees may vary
• No oversize surcharge data

Pricing: Free. Platforms: Web Best for: Travelers who want a quick weight-based estimate and don’t mind confirming the fee on the airline’s site before booking.

7. Confused.com Airline Baggage Calculator

Confused.com’s calculator is a UK price comparison site that includes an airline baggage fee lookup. Select your airline and cabin class, and it shows luggage allowances and fees for that combination.

Pros:

• Covers European carriers that US-focused tools often miss entirely
• Clean interface integrated into a broader travel insurance and planning site
• Cabin class filtering adjusts results, since bag allowances differ between economy, premium, and business on many airlines
• Free, no account needed

Cons:

• UK-focused, so US domestic travelers won’t find it as relevant
• Fee data was captured from airline websites “as of October 2024” per their own disclaimer, meaning 2026 fee changes are likely not reflected
• More of a fee lookup than an interactive calculator
• If your airline isn’t listed, you’re told to check the airline’s own site

Pricing: Free. Platforms: Web Best for: UK-based travelers or anyone flying European carriers who want a quick allowance and fee reference.

The Bottom Line

If you want to compare checked bag fees across airlines before booking, our Checked Bag Fees tool gives you the widest standalone comparison with the overweight and oversize surcharges that other tools skip. It’s free, there’s no signup, and every fee links back to the airline’s official source. Yes, it’s our tool. I still think it’s the right answer for anyone who wants to compare fees without entering booking details or starting a flight search.

If you’re already searching for flights, Google Flights is the easiest way to see total cost with bags included. You don’t have to open another tab. KAYAK does the same thing if that’s where you search. For specialty luggage like golf bags, surfboards, or musical instruments, iFlyBags has the deepest coverage at 300+ airlines, though the interface shows its age.

None of these tools replaces checking the airline’s own site before you fly. Published fees are standard rates, and your actual cost might be lower with elite status or the right credit card. If you’re looking for strategies to pay less or skip bag fees entirely, we have a full guide on how to avoid checked baggage fees in 2026. And if you’re still deciding what luggage to bring, our carry-on size checker and personal item size checker can tell you whether your bag will actually fit before you leave the house.
