If something cost $1 in the 1980s, what does it cost now?

If something cost $1 in the 1980s — or the 1990s, or 2000, etc — what does it cost now?

I used to use a calculate this by using a rough 1:3 ratio in terms of 1980s dollars:today’s dollars, but there is a better way. You can go to the site in2013dollars.com and enter your information and it will spit out an answer. For example, what cost $1 in 1980 would cost $3.62 today, according to this: $1 in 1980 → 2023 | Inflation Calculator

I used that site because I was reading that in the early 80s Jim Jarmusch had an apartment in Manhattan that cost $170 a month. I wondered: what would that cost now? Well according to the site above, in 2023 that same place should cost $615. Of course the idea that ANYPLACE in Manhattan cost $615/month is hilarious. But you get the idea. 🙂
