How does your purchasing power actually change? Here's the real breakdown — after taxes, after cost of living.
What the numbers mean
A $75,000 salary in New York City gives you the equivalent of $35,936 in purchasing power after accounting for state income taxes (10.4%) and the local cost of living. The same salary in Miami gives you $60,976 — a difference of +70%.
Median rent in Miami runs about $2,100/month — roughly $1,100/month less than New York City's $3,200. That's $13,200/year back in your pocket before you factor in anything else.
No state income tax in Miami. On a $75,000 salary, that's roughly $7,800/year you keep that you wouldn't in New York City.
These numbers use a cost-of-living index where 100 = national average. New York City's index of 187 means it costs 187% of the national average to maintain the same lifestyle. Miami's is 123.
What it actually feels like
NYC to Miami is a move with a real reputation, partly because finance industry people kept making it during 2020-2022 and partly because the math works on paper in a way few other moves do. The above purchasing-power gap is real, but a couple of things about Miami specifically don't show up in any cost-of-living index, and they're worth weighing before you sign anything.
Insurance is its own line item now. Florida's homeowners insurance market is in a state most cost-of-living calculators haven't caught up to. Average Florida homeowner premiums have roughly tripled in five years, and Miami-Dade is one of the hardest-hit counties because of hurricane exposure. If you're buying a single-family home in Miami, expect $4,000 to $9,000 a year in homeowners insurance, plus a separate flood policy if you're in a flood zone (and a lot of Miami is). Renters dodge most of this directly but pay it indirectly — landlords pass insurance increases through to rent, which is part of why Miami rent has climbed so fast even as the rest of the country flattened.
Condos have a separate problem. After the 2021 Surfside collapse, Florida changed its condo recertification laws. Older buildings (over 30 years) now require structural inspections, and many have been hit with five- and six-figure special assessments to bring buildings up to code. HOA fees in Miami condos that looked reasonable on Zillow can include or exclude these assessments, and the listing won't always tell you. Talk to current residents before signing anything.
The tax math is genuinely excellent. NYC takes 6.85% in state income tax plus 3.876% in city tax on a $75k salary — that's almost $7,800 a year you'd keep simply by becoming a Florida resident. The savings scale up dramatically with income; a New York banker making $400,000 keeps roughly $50,000 a year more in Miami than in Manhattan. This single-handedly explains why a chunk of the finance industry made the move in 2020-2022.
Miami summer is a weather event, not just a season. Summers run from May through October. Daytime temperatures stay in the low 90s, but the humidity is the load-bearing variable: the wet-bulb temperature in August Miami is genuinely uncomfortable in a way that most Northerners haven't experienced. The afternoon thunderstorms are real and disruptive. Hurricane season is June through November, and even when nothing major hits, the threat reshapes your life every September. People who like Miami learn to plan their lives around it. People who don't, leave.
The cost of living index understates Miami a bit. Miami's COL index of 123 is real but it averages across neighborhoods. The neighborhoods most NYC transplants want to live in — Brickell, Wynwood, Coconut Grove, Coral Gables — price closer to a 145-160 index. The cheaper Miami exists (Little Havana, parts of Hialeah, Kendall) but the cultural and walkability gap from those to Manhattan is bigger than the gap to, say, Brickell. So budget for the higher end of the Miami range if you want a Manhattan-equivalent lifestyle.
What you actually gain. Apartment size doubles. Outdoor life in winter is real. Beach access is real. The food scene is excellent and underrated by people who haven't been recently — Miami's restaurants now compete seriously with anywhere outside of NYC, LA, and SF. The Cuban coffee at any cafecito window is $1.50. There's a reason the move stuck for so many people who tried it.
For high earners with portable jobs, this move's math is among the strongest in the country. For middle-income renters, it's a smaller but still real win, with weather and insurance pass-through as the main risks to plan around.
