Overweight Baggage Fee Calculator
Check how far a checked bag is over the airline limit and estimate the overweight fee before you get to the counter.
How it works
Amount over = bag weight − allowance · Fee due = overweight fee if bag weight > allowance, otherwise 0
Most airlines charge a flat overweight fee once a checked bag passes the included allowance (commonly 23 kg / 50 lb in economy), then a higher tier once it passes a second threshold such as 32 kg / 70 lb. This calculator compares your bag to the limit you enter and applies the flat fee only when you are over. Redistributing a few items into a carry-on is often cheaper than paying the fee.
Worked example
A 26 kg bag against a 23 kg allowance is 3 kg over the limit, so the airline’s flat overweight fee — say $100 — applies. Moving 3 kg into hand luggage would avoid it entirely.
Frequently asked questions
Is it cheaper to pay the fee or take a second bag?
It depends on the airline. A second checked bag fee is sometimes lower than a single overweight charge, so if you are well over the limit, splitting into two bags can cost less. Compare the two before you pack.
Do the overweight and oversize fees stack?
Often, yes. A bag that is both too heavy and too large can be charged an overweight fee and an oversize fee at the same time, which is why very heavy suitcases get expensive fast.
What are typical weight limits?
Economy checked bags are usually capped at 23 kg (50 lb), with a higher overweight tier up to 32 kg (70 lb). Premium cabins often allow 32 kg per bag. Always confirm with your specific airline and fare.
