Baggage Overweight Calculator
Find how far a packed baggage weight exceeds an entered allowance, with zero excess when it is within the limit.
How to use Baggage Overweight Calculator
1. Enter Packed Baggage Weight, Baggage Allowance, Weight Unit. 2. Both values use the same selected kg or lb basis; the selector does not convert filled values. Airline limits, rounding rules and excess charges are not retrieved. 3. Select Calculate or press Enter. 4. Select Copy result to copy the answer, or Reset to clear the form and result.
Why use this tool?
Find how far a packed baggage weight exceeds an entered allowance, with zero excess when it is within the limit. Both values use the same selected kg or lb basis; the selector does not convert filled values. Airline limits, rounding rules and excess charges are not retrieved.
How the calculation works
Excess weight = max(packed weight − allowance, 0). Both values use the same selected kg or lb basis; the selector does not convert filled values. Airline limits, rounding rules and excess charges are not retrieved. Durations round to the nearest second; other quantities round to at most six decimals (percentages to two). Nonzero subprecision values are identified.
Example
Worked example: Packed Baggage Weight = 25; Baggage Allowance = 23; Weight Unit = "kg". Result: 2 kg.
Practical tip
Include the bag itself in packed weight if the applicable allowance covers the whole bag.
