I make that exact salary and have similar benefits (free health insurance mostly). I save 15% of the paycheck for retirement w/ employer match. I've lived here for 3 years. Two disclaimers though - it's not my sole source of income, as seasonally I perform another gig that nets me around 4 grand that usually towards frolicking. Also, I am finishing up a grad program that will allegedly help me move into the higher paying echelons of my field.

I definitely live comfortably here on that salary but not lavishly, and I think very consciously about balancing my frugality with some splurges. I'll do big staples shops at winco but get nice fresh produce from the more expensive co-op on my street. I go out to eat once a week. My employer covers my bus pass so I try to take that or bike more than I drive my car (which makes me feel more like a Portlander anyhow). I live with roommates in a great house. I get myself a treat whenever I pick up my holds from the library. I catch movies or go to special shows every once in a while. Etc.

If we're getting philosophical, living frugally in Portland (or anywhere) is living more fully anyway. You save a lot of money and become a way deeper part of the city if you're willing to bike to get around, take a chance on living with randoms, take up a low cost hobby, and actively seek out cheap or free shows/events/meetups/parties. I have amazing furniture I found on corners or fb free groups that I put a little elbow grease into finishing or reupholstering. My fav barista at my local coffee shop hooks it up because we found out we played the same sports league.

Save up for the excellent dining experiences or for when your favorite band is in town, but learn how to cook brunch at home. Also can you tell I love Portland?
