I've tried to calculate this for the New York City Metro, but they spend about $1 billion per year collecting $5 billion per year, out of a budget of $20 billion per year. Year so they would need to make up about $4 billion per year if they were to eliminate fare collection, or increase the budget by 20%.
In my mind it would be a no-brainer for all the benefits you would get from free service, but 20% increase in cost is not an easy sell - especially when a lot of people paying tax on it never go to NYC
