Mathematical Audit

Luggage Cost & Weight Optimization Formulas

Models checked baggage fees against standard limits, assessing overweight charges and compared shipping tariffs to determine the most economical logistics strategy.

Total Airline Checked Fee = Base Checked Fee + Overweight Fee + (Extra Bags × Extra Bag Fee)
Where Overweight Fee = $0 (w <= 50 lbs), $100 (50 < w <= 70 lbs), or $200 (70 < w <= 100 lbs)
Total Shipping Cost = (1 + Extra Bags × 0.8) × (Shipping Base Fee + Extra Weight × Shipping Rate per Lb/KG)
Weight Over Limit = Max(0, Actual Weight - 50 lbs)
Potential Packing Redistribution Savings = Overweight Fee

Units are normalized between pounds (lbs) and kilograms (kg) (1 kg = 2.20462 lbs) to maintain uniform comparison with domestic and international carrier limits.

Real-World Scenario Example

"A traveler has a 65 lb suitcase, flying on an airline with a $35 checked bag fee, $100 overweight fee for 51-70 lbs, and compares it to a $85 luggage shipping service (including 50 lbs base, and $1.50/lb extra)."

Inputs

bagWeight:65
weightUnit:lbs
airlineCheckedFeeBase:35
airlineOverweightFeeLow:100
airlineOverweightFeeHigh:200
shippingBaseRate:85
shippingRatePerUnit:1.5
shippingBaseWeightLimit:50
extraItemsCount:0
extraBagFee:45

Result

Airline fee total is $135 (includes a $100 overweight fee). Shipping the bag costs $108. Shipping saves $27. Alternatively, shifting 15 lbs to a carry-on reduces the airline fee to $35, saving $100.
