A 30-day unlimited RTD pass will set you back $99 each month.
If you make about $27,000 a year, like ValuePenguin says the average Denver transit user does, then that means you spend about 4.4 percent of your income on commuting. That's above their national average of 3.6 percent.
Those figures don't put Denver in the top 15 most expensive metros, but for people who think the city already lacks affordable transit options, it's not great news.
Even Boulder managed to look more affordable than Denver in this study, though that's only because public transit users had a slightly higher income there.
