Frequently asked questions
Where do the allowances and fees come from?
They come from a four-row table inside the tool, not from any airline: budget carry-on 8 kg and checked 20 kg, full-service domestic 10 and 23, full-service international 10 and 23, ultra-budget 6 and 20. Overweight fees are 15, 25, 50 and 20 per kg, and extra-bag fees are 40, 35, 60 and 50. Airline rules and prices change and differ by route and fare, so confirm the allowance with your airline before relying on any result.
Which currency are the fees in?
The fees are shown with a dollar sign and are fixed numbers from the table. No currency conversion is applied. If your airline charges in another currency, treat the output as a rough scale only.
How is the overweight fee calculated?
Excess kilograms × the per-kilogram fee for the selected airline type. A 25 kg checked bag on the budget row is 5 kg over the 20 kg allowance, so 5 × 15 = $75. A bag at exactly the allowance shows "Exactly at the limit" with no fee.
Are the fees charged per full kilogram?
No. The tool multiplies the fractional excess, so 1.5 kg over costs 1.5 times the rate, rounded to whole dollars in the display. Some airlines charge in weight bands or flat steps instead, which can be higher or lower. The tool does not model those.
What does the Additional Bags field do?
It multiplies the number of extra bags by the flat extra-bag fee for the airline type. The tool does not weigh those bags, so each is assumed to be within its own allowance. Two extra bags on the ultra-budget row cost $100.
Does it check carry-on size or personal items?
No. Only weight against a single limit is checked. Dimensions, a separate personal item, liquids rules, or restrictions on weight for items such as sports equipment are outside the tool.
Why does a carry-on appear to cost an overweight fee?
Because the tool uses the same per-kilogram fee for carry-on and checked bags. An 11 kg carry-on on the ultra-budget row is 5 kg over a 6 kg limit and shows $100. In practice airlines may refuse an overweight cabin bag or require it to be checked, so the displayed fee is an illustration.

How to use the luggage weight calculator

The tool shows whether you're within limits and calculates any potential overweight fee. Free and instant on any device.
How the luggage weight calculator works
The luggage weight calculator compares your entered bag weight against standard airline weight limits (7 kg carry-on, 20–23 kg checked for economy) and flags overages. Excess baggage fee estimates use average published airline fee tables. All calculations run locally in your browser with no data uploaded.
What is compared
You enter the weight of one bag, pick an airline type and say whether the bag is checked or carry-on. The tool takes the matching allowance from its table, subtracts it from your weight and reports the difference in kilograms. If the bag is over, the excess is multiplied by that airline type’s per-kilogram rate. Extra bags are charged a flat fee each. All figures are the tool’s built-in estimates and are shown in dollars.
| Airline type | Carry-on (kg) | Checked (kg) | Over per kg | Extra bag |
|---|---|---|---|---|
| Budget | 8 | 20 | $15 | $40 |
| Full-service domestic | 10 | 23 | $25 | $35 |
| Full-service international | 10 | 23 | $50 | $60 |
| Ultra-budget | 6 | 20 | $20 | $50 |
Worked examples
Outputs below were obtained by running the calculator.
| Bag and airline type | Allowance | Result | Fees |
|---|---|---|---|
| 22 kg checked, full-service international | 23 kg | 1.0 kg under | None |
| 25 kg checked, budget | 20 kg | 5.0 kg over | $75 |
| 11 kg carry-on, ultra-budget, 2 extra bags | 6 kg | 5.0 kg over | $100 overweight, $100 extra bags |
| 23 kg checked, full-service domestic | 23 kg | Exactly at the limit | None |
Reading a result near the limit
A bag 1 kg under the allowance is safe on paper, but kitchen scales and airport scales can disagree by several hundred grams, and items bought on the trip add weight. If you are within about 1 kg, remove a heavy item or move it to a personal bag. If you are over by only a little, compare the displayed fee with the cost of posting the item or paying for an extra bag.
Choosing between paying and repacking
On the budget row, 5 kg over costs $75, whereas an extra bag costs $40. In that case adding a bag and splitting the load is cheaper than paying for the excess, as long as the extra bag is itself within its allowance. On the full-service international row the excess rate is $50 per kg, so even 2 kg over is $100, which is more than its $60 extra-bag fee. Check both options in the tool before you decide.
Check the airline, not just the table
Airlines set their own allowances, which can vary with route, fare class, loyalty status and cabin. The categories here are broad groupings and the dropdown examples are only labels. Read the baggage page for your fare, and weigh your bag after packing. Treat the fee estimates as a way to compare scenarios, and never as a quote. If you travel with several airlines on one trip, run the tool once per airline type, since a bag that is fine on one leg may be over on another.
