New York, NY versus Boston, MA: the composite cost-of-living index difference is about -13%, putting the move in the "lateral" zone where lifestyle, climate, career, and tax factors usually outweigh pure cost considerations. At this scale of gap, the noise inside the index (sampling variation, year-over-year price drift, individual basket differences) is roughly the same size as the signal between the two cities.
What is worth checking: are there meaningful state-tax differences between New York and Massachusetts? Is the housing sub-index gap larger or smaller than the composite gap, indicating that the categories you actually spend on diverge from the average mix? The sidebar and the tables below break out these dimensions so you can stress-test whether the lateral classification holds for your specific situation.
State income tax is not part of the cost-of-living composite, but it is part of your real take-home math. New York's effective top rate is 6.85%; Massachusetts's is 5.00%. On a $75,000 salary the two states pull $5,138 and $3,750 respectively — a gap of $1,388 that compounds with the consumer-price difference.
Use the take-home pay calculator to model the after-tax difference at your specific salary and filing status. Federal tax stays constant across the move; only the state piece moves. See the take-home pay calculator or the state-by-state take-home pay article for the precise after-tax number.
No — Boston comes in about 13% cheaper on the composite (162 vs 187 for New York). Housing carries most of the gap, with smaller contributions from grocery, transport, and utility sub-indexes.
The equivalent salary in Boston is about $64,973. You get there by multiplying $75,000 by the index ratio (0.87, derived from 162 and 187). This is a consumer-price comparison; layer state tax separately for after-tax parity.
Housing is the largest line item in any cost-of-living comparison and the one with the most metro-to-metro variance. New York's housing sub-index sits at 232; Boston's is 215. That gap reflects rent and home-price differences captured in the C2ER ACCRA quarterly survey. Groceries (New York 117 vs Boston 110), transportation (134 vs 116), and utilities (165 vs 138) all contribute, but housing is the dominant factor.
Not directly. Consumer-price indexes like C2ER ACCRA exclude state and federal income tax. To get the full picture for New York versus Massachusetts, combine the equivalent-salary number above with the state-tax delta in the sidebar; both effects compound when you cross state lines.
