Meeting planners everywhere know that cost is one of the most important factors to consider when organizing an event. The cost of venues, hotel rooms, food and beverage, as well as other necessities, can vary widely depending on the event’s location. In order to get the most bang for their buck, planners need to do their research and choose wisely.

Recently, Business Travel News published its 2016 Corporate Travel Index, which ranks the most expensive cities for business travelers. The rankings are based on data gathered from hotel room, car rental and food per diems paid in 2015. In the United States, the average per diem was $318.80, which comes from a combination of $172.80 spent on accommodations, $47.12 for car rentals and $98.74 for food.

With average per diems of $547.34, San Francisco has been named the most expensive U.S. city for business travelers. This is the city’s third straight year atop the rankings. In recent years, San Francisco has made headlines with its growing tech start-up scene, soaring wages and rising living expenses. It beat out similarly high-priced contenders such as New York City and Boston, which also topped $500 in average per diem expenses. Four California cities made the top 10, cementing the state’s reputation as one of the priciest in the United States.

Below are the top 10 most expensive locations in the U.S. for business travelers.
