144 million dollars button

The New York taxi driver executes orders for an average of $ 90,747 per year . There are approximately 13,267 taxis in the city. In 2007, the authorities in New York ordered them to accept bank card payments, with the installation of a touchscreen for payment.

In the process of calculation, the user is offered three default buttons for tips: 20%, 25% and 30%. When taking cash only, the average tip was about 10%. After putting the system into operation, the percentage of tips jumped to 22% .

$ 144,146,165 extra tip. In year. Agree, these are very valuable buttons.

Note 1: From the total amount of payment, you need to deduct the bank transfer fee for non-cash transfer (in the NYT article it is about 5%).

Note 2: The estimate of the previous average tip of 10% is based on the amounts that the taxi drivers handed over to the cashier. In reality, they hid part of the tip.

In any case, this story shows the importance of the default settings in the interface. After all, the user can enter an arbitrary amount manually, but it is much easier for him to press one of the three buttons. No wonder if more than 90% of all taxi passengers do this, except for the most important ones.
