Work out excess baggage fee instantly with clear inputs, formula shown and shareable results.

Excess baggage
excess = max(weight - allowance, 0); fee = excess x per-kg rate, subject to a hard maximum weight
Manual handling regulations. Above that, baggage handlers face injury risk, so airlines refuse the bag rather than charge more.
For anything over about 10 kg excess, an unaccompanied shipment or courier is usually cheaper — though far slower.
