I think u/derpbeluga gave you a great breakdown of practical costs. Just for a statistical view (which I always find helps me put my own financial circumstances in perspective) the median household income in RI is $74,489 (according the 5-year average of the US Census Bureau's Annual Community Survey between 2017-2021). Meanwhile, households on average contain 2.46 people. So, you'll almost certainly be doing better than the majority of households with two or more people in RI.
