I listed the annual cost for one system. I did not add the costs for policing, the turnstiles, station staff to man the turnstiles, or any of a dozen different adjacent costs. My numbers in no way should be seen as a comprehensive total cost.
The largest share of MTA revenue — $7.222 billion — comes from dedicated taxes and subsidies the Authority receives from the cities and states that we serve. Another $6.870 billion comes from fares and tolls. Federal COVID-related aid, which the MTA received in 2020 and 2021, adds up to $2.877 billion.
Total budget is $19.379 billion.
