The Hidden-Fee Index

The advertised price is rarely the price you pay. This is how much it hides — the sticker plus every extra you actually have to pay to use the thing — across everyday categories. It reports on categories and fee types, never a single business.

HOW THIS IS MEASURED · UPDATED 2026-08-05

For each category we add up every disclosed extra on the example items in our calculator and divide by the advertised price, then average across the examples. It is computed live from our own models, so it moves as the data does. These are illustrative sample figures today and switch to live feeds at launch. Full method: True Cost Methodology.

Read as: for every €100 on the sticker, this many euro extra before you’ve finished paying. Fee names are generic types, not brands.

Frequently asked

What counts as a hidden fee?

Any cost that the advertised or sticker price leaves out but you still have to pay to actually use the thing — for example checked-bag and seat fees on a flight, excess-waiver cover and fuel policies on car hire, or ink over the life of a printer.

How is the Hidden-Fee Index calculated?

For each category we take the example items in the TrueTotal calculator, add up every disclosed extra, and express it as a percentage of the advertised price, then average across the examples. It is computed live from our own category models, so it updates as the data does. Figures are illustrative sample data today and move to live feeds at launch.

Does the Index favour any particular company?

No. The Index reports on cost categories and fee types only — it never names or ranks an individual business, and TrueTotal never sells rankings.

Which categories hide the most?

Categories with large recurring or add-on costs tend to hide the most as a share of the sticker — consumables like printer ink, and travel where bags, insurance, fuel and on-site fees stack on top of the headline price.
