Drip Pricing and Hidden Fees

How businesses reveal extra charges gradually during checkout, why this raises what people pay, and how regulators are responding.

You see a concert ticket advertised for 2,000 rupees. By the time you reach the final payment screen, “convenience fees”, “service charges” and “handling fees” have pushed the total much higher. This practice is called drip pricing: revealing additional charges bit by bit during the buying process.

Why businesses do it

Drip pricing works because of how people make decisions:

Anchoring: the low headline price sticks in people’s minds.
Sunk effort: after spending time selecting seats or entering details, people are reluctant to start over elsewhere.
Comparison is harder: if competitors advertise total prices, the drip-pricing business looks cheaper at first glance.

Evidence

Research by economists including Steven Tadelis and colleagues studied a large online ticket platform that tested showing prices with and without fees upfront. When fees were revealed only at checkout, customers spent significantly more and were less likely to leave the site. Hidden fees shifted spending and made shoppers less price-sensitive.

Common examples

Airline fees for seats, bags and payment methods.
Hotel “resort fees”.
Ticket booking fees.
Food delivery surcharges.
Utility and bank charges not shown upfront.

Regulation

Regulators are acting against drip pricing:

The U.S. Federal Trade Commission issued a rule, effective in 2025, requiring the total price of live-event tickets and short-term lodging to be shown upfront.
The UK’s Digital Markets, Competition and Consumers Act 2024 bans drip pricing of mandatory fees.
In India, the Central Consumer Protection Authority issued guidelines in 2023 against dark patterns, including drip pricing.

Comparing two websites

Website A lists a hotel room at 4,000 rupees and adds 800 rupees of fees at checkout. Website B lists the same room at 4,500 rupees including everything. At first glance, A looks cheaper, but B is actually cheaper. A shopper who compares only headline prices will choose the more expensive option.

Protecting yourself

Always compare the final total price, including all mandatory fees, before deciding. Going through to the last step on several websites before paying helps reveal the true cost.

Thinking the advertised price is what you will pay

In many online purchases, the advertised price excludes mandatory fees. The only price that matters for comparison is the final amount you actually pay.

Key takeaways

Drip pricing reveals extra charges gradually during checkout.
It works through anchoring and the effort already invested in a purchase.
Studies found hidden fees lead customers to spend more.
Regulators in the U.S., UK and India have acted against drip pricing.
