See Your Bag Weight Against the Limit Before You Pay
The overweight fee is not bad luck — it's a number you could have calculated at home. This takes the items you actually packed with their weights, totals them against your allowance, prices the overage at your airline's rate, and ranks the heaviest movable items so you know exactly what to shift into carry-on. Local only; the list never leaves the tab.

What you pay otherwise
| Route | What you get | Cost |
|---|---|---|
| Overweight fee at the desk | Charged per kilo over, with a queue behind you | $12/kg |
| A second checked bag | Cheaper than the overage, still avoidable | $45+ |
| Leaving something behind | Whatever the airline decided you'd lose | your choice made for you |
| This page | The overage priced, and the fix named | $0 |
The workflow
List items with weights, one per line
'Jeans x4 | 2.1' or 'Toiletry bag | 0.9'. Weights are kilograms — use a luggage scale or a bathroom scale with the bag minus your own weight. Estimates are fine; a 0.4 kg error is not what costs you the fee.
Enter the allowance for the fare you actually bought
Basic economy and standard economy often differ by 5 kg, and the number on your confirmation is the one the desk uses. Enter the bag weight limit, not the total including carry-on.
Read the fee line before the item list
The overage priced at your airline's per-kilo rate is the number worth avoiding. If the fee is smaller than the cost of a second bag, the calculation changes — and now you know that before the desk tells you.
Move the ranked items, not the sentimental ones
The tool ranks by weight, heaviest first, because that's what clears the limit fastest. Denim and shoes move easily; the toiletry bag usually can't go in carry-on at all, which is why it's marked.
Worked example
Sample: 14 items, 23 kg allowance, $12/kg Total 26.4 kg Overage 3.4 kg Fee at desk $40.80 Move first Jeans x4 (3.6 kg) clears it alone Locked out Toiletry bag (1.1) — liquids, cannot go in carry-on Uploaded nothing — totalled in the tab
Numbers above are sample data produced by the tool's own pre-loaded example, run in the browser — not averages or measured benchmarks.
What breaks this
Estimating the bag's own weight as zero understates every total by 2–4 kg — weigh the empty bag once and add it as a line. Using the carry-on limit for a checked bag compares against the wrong number. Assuming liquids can move to carry-on is how people re-pack twice; the tool marks toiletries as non-movable for that reason.
Try it now
A 26.4 kg bag against a 23 kg allowance is loaded and prices a $40.80 fee. Move the boots to carry-on and watch the fee fall to zero.
