Honolulu is roughly 24% more expensive overall, and housing is doing almost all of the work: a one-bedroom runs $1,500 in Baltimore against $2,100 in Honolulu.
Housing does most of the damage
Strip out housing and most US metros cost about the same. Housing is where the difference lives. A one-bedroom runs about $1,500 a month in Baltimore and $2,100 in Honolulu — $600 a month apart, or $7,200 a year.
Ownership widens the gap. $220,000 buys the median home in Baltimore; $850,000 does in Honolulu. The down payment alone differs by roughly $126,000, and that is before Maryland and Hawaii property tax rates diverge.
The price-to-rent ratios diverge enough to change the buy-versus-rent answer: about 12 in Baltimore versus 34 in Honolulu. Below roughly 15, buying tends to win over a normal holding period; above roughly 20, renting and investing the difference usually does. Which means the right answer can genuinely be to buy in one and rent in the other.
Taxes the index leaves out
There is a city-level tax to account for as well: Baltimore charges about 3.20% local income tax, while Honolulu charges none. On $100,000 that is roughly $3,200 a year, deducted before you ever see it and easy to miss when comparing two offers.
Getting around
Baltimore is served by limited transit; Honolulu is workable without a car in many neighborhoods.
Work, weather, and what else is different
Baltimore is a large metro of about 2.8M and losing population; Honolulu is a mid-size metro of about 1.0M and roughly flat.
Different economies entirely: healthcare/biotech, port/logistics, higher education drive Baltimore, with Johns Hopkins University & Hospital and Port of Baltimore among the anchors, against tourism/hospitality, military/defense, government in Honolulu where U.S. Pacific Fleet/Joint Base Pearl Harbor-Hickam and Queen's Health Systems dominate. Treat this as a career move as much as a relocation.
Weather is not a rounding error when you actually live somewhere. Baltimore: Humid subtropical/continental transition: January highs near 41°F/lows 26°F, July highs near 88°F/lows 70°F, humid summers. Honolulu: Consistent tropical climate year-round: January highs near 80°F/lows near 66°F; July highs near 88°F/lows near 74°F, with trade-wind breezes moderating humidity.
Baltimore City levies the maximum local income tax allowed under Maryland law (3.2%), stacked on top of the state's graduated income tax; city population has declined for decades even as the metro overall stays roughly stable. Hawaii's state income tax reaches 11% at the top bracket, and virtually everything (groceries, fuel, goods) is shipped in, driving one of the highest overall costs of living in the US.
Overall cost ratios come from BEA Regional Price Parities. Housing figures track published market data and local tax rates come from the municipalities themselves. How these are compiled and updated.
