Excess Baggage Fee Calculator

Airlines use one of two systems. Under the weight concept, you get a total kilogram allowance and pay a per-kilogram rate for anything over it (excess kg × fee per kg). Under the piece concept, you get a fixed number of bags included, and each extra bag beyond that is charged a flat fee. This calculator supports both, and adds them together if both apply to your ticket.

The weight concept totals up all your checked baggage weight against one allowance (common in Europe, Asia and Africa). The piece concept instead counts individual bags, each within its own weight/size limit, and charges per extra bag (typical on flights to and from North America). Check your ticket or airline's baggage page to see which one applies.

It varies widely by airline, route and how you pay — often anywhere from $30 to $200+ per extra bag, and usually cheaper if you prepay online rather than at the airport. Enter your airline's actual per-bag fee to get an accurate estimate.

This depends on the airline's per-kilogram rate and how far over the free allowance your bag is. For example, a bag that's 5 kg over a 23 kg allowance at a $12/kg rate costs 5 × $12 = $60. Some airlines instead charge a single flat fee for any bag in an overweight band (commonly 23–32 kg) — if yours does, enter that flat amount instead of a per-kg rate.

IATA advises a maximum of 23 kg (50 lb) per checked bag in economy, with an absolute limit of 32 kg (70 lb) — heavier bags are typically refused rather than priced, since they exceed manual handling limits. Business and first class often allow up to 32 kg. Your specific ticket's allowance can differ, so always check it directly.

You can reduce or avoid them by weighing your bags before you leave, redistributing weight between checked bags (if you're within your piece allowance), prepaying for extra baggage online (usually far cheaper than at the airport), or choosing a fare/status tier that includes a larger allowance.

No — it deliberately does not look up any airline's fee schedule, because those change frequently and vary by route, fare class and booking channel. You enter your own allowance, per-kg rate, included bag count and per-bag fee (from your ticket or airline's website), and the calculator does the arithmetic.

These are two independent charges that can both apply: your total or per-bag weight can push you over your weight allowance, and separately, the number of bags you're carrying can exceed the number included with your ticket. This calculator adds both charges together for a transparent, conservative estimate — if only one applies to your airline, set the other side's inputs so it computes to zero.

Enter one passenger's allowance, weight and fees, then set the number of travelers. The calculator multiplies that single passenger's total fee by the traveler count, assuming everyone has the same allowance and the same overage. If travelers differ, calculate each one separately and add the results.

Almost always online. Most airlines charge significantly more for excess or extra baggage paid at check-in or the gate than for the same bag prepaid through the airline's website in advance — the UK Civil Aviation Authority specifically flags this gap for travelers.

Multiply pounds by 0.45359237, or divide by 2.2046226, to get kilograms. For example, a 50 lb bag is 50 × 0.45359237 ≈ 22.68 kg. Enter the kilogram figure into this calculator alongside your airline's kilogram-based allowance and rate.

Many airlines simply refuse to check a bag over 32 kg (70 lb) rather than charging for it — you'd need to repack it into two bags or ship the extra weight separately as cargo. This calculator's linear per-kg estimate does not reflect that hard refusal cutoff, so treat a very large excessKg figure as a sign you need to repack, not just pay more.
