Chef Gordon Ramsay couldn't save every kitchen from its nightmares. 

More than 60% of restaurants featured on the show "Kitchen Nightmares" are now closed, according to Grub Street New York, which did the math. Approximately 30% of those kitchens closed within one year of their episode's air date.

The show announced earlier this week it would end its 10-year run.

Considering the current closure rate of restaurants, Ramsay's success rate might not seem so bad. About 30% of restaurants fail in their first year, and another 30% fail sometime in the following two years, according to the National Restaurant Association.

On a positive note, around 39% of restaurants featured on the show are still open. Those include the infamous Amy's Baking Company, the Arizona restaurant that had a complete social media meltdown after Ramsay stormed out during the episode. Amy's Baking Company closed for a brief time and later reopened without much fanfare.

"Kitchen Nightmares" will air four more episodes.
