Cost of living compares prices across places at one point in time. The related question — how prices in one place have changed over time — is answered by inflation. To see what an income or price from an earlier decade is worth in today's money, see what old money is worth today, which converts any amount from 1913 onward using Consumer Price Index data.
Don't forget state taxes
