The MTA will lose millions of dollars over the next couple of years — as fewer and fewer people want to deal with the agency’s poor service.

The cash-strapped agency projected $376 million shortfall in fares agency-wide over the next four years — that’s about $90 million a year.

Chairman Joe Lhota blamed the dwindling in money and ridership on a “combination of things,” including the quality of service, for hire vehicles like Uber and Lyft — as well as people jumping turnstiles.

“When you have choice you take advantage of the choice,” he said at a press conference on Wednesday.

Fewer people have been hopping on slow and delayed subways and buses all over the city with a loss of 69 million rides between 2016 and 2017, according to MTA data. The steepest declines were in the Bronx and Queens where ridership plummeted 8.2 percent and 6.6 percent respectively, between May 2017 and May 2018.

But the MTA budget will still break-even in 2018 and 2019, then will see a deficit of $634 million in 2022.

MTA board members discussed an upcoming fare hike, which has been scheduled since 2009 — wondering if they can make up that revenue somewhere else instead of laying the burden on the backs of commuters.

“What adds insult to injury is when performance sucks,” said board member Lawrence Schwartz about the 4 percent increase. “We have to focus on performance… the days of inefficiency, the days of waste have to end,” he added.

The final decision on the fare increase will be made sometime next year.
