Hawaii cities compared

Both Hawaii metropolitan areas on the same $100,000 salary and the same $400,000 home, with the income tax identical in each — so the whole difference is property tax and the price level.

Kahului and Urban Honolulu, resolved side by side

Hawaii has 2 metropolitan areas with a published price index, and on $100,000 with a $400,000 home they are not interchangeable: $66,469 of purchasing power in Kahului against $65,110 in Urban Honolulu — $1,359 a year, 1.4% of the salary, without leaving the state.

That gap is unusually easy to trust, because the income tax is identical in every row. Federal $13,170, FICA $7,650, Hawaii state income tax $5,796, and no county or city in Hawaii levies its own. Two things move down this table and only two: what a house costs in property tax, and what everything costs at the till.

Purchasing power on a $100,000 salary with a $400,000 home: take-home after federal, FICA, Hawaii income tax and property tax, divided by that area’s price level. The income tax is identical in every row — the whole of the spread is property tax and the price level. Price index 100 is the US average.

Every one of them prices above the national average, which is why the state figure never looked cheap.

Property tax runs from 0.17% in Kahului to 0.28% in Urban Honolulu — on a $400,000 home that is $672 against $1,137 a year, a difference of $466. Each rate is that area's counties averaged and weighted by how many homes are in each, because a house pays the tax and a rural county of a few thousand homes should not weigh the same as an urban one of several hundred thousand.

The 1 Hawaii comparisons, resolved

Every pair of Hawaii cities, each on its own page with the full working, the break-even salary and the property tax bill house by house. Ordered by the population that could plausibly be choosing between them:

Kahului vs Urban Honolulu — Kahului by $1,359 a year. Price level 109.393 against 110.961; property tax 0.17% against 0.28%.

Every Hawaii city, and what it can be compared with

The areas themselves, largest first. Each line has what defines that city on the two measures that matter here, and then every comparison it takes part in:

Urban Honolulu — 1.0m people across 1 county. Price level 110.961, housing 135.538, property tax 0.28%. Compared with Kahului.

Kahului-Wailuku — 165k people across 1 county. Price level 109.393, housing 119.179, property tax 0.17%. Compared with Urban Honolulu.

The counties behind each rate

Nobody pays a metropolitan area's property tax rate. They pay their county's, and the figures above are those county rates averaged and weighted by how many homes each county holds. Opened up:

Urban Honolulu averages 0.28% across 1 county: Honolulu County 0.28%. One county, so the area rate is that county's rate exactly — no averaging involved.

Kahului averages 0.17% across 1 county: Maui County 0.17%. One county, so the area rate is that county's rate exactly — no averaging involved.

Which is the limitation of every figure on this page, stated rather than buried: an area rate is an average, and your address decides what you actually pay. The county pages linked above carry the rate, the assessment basis and the source for each one.

Where Hawaii cities sit among the 380 in the country

A state ranking answers "where in Hawaii". It does not answer whether Hawaii is an expensive place to begin with, and the two questions have different answers often enough to be worth separating.

Against all 380 metropolitan areas the Bureau of Economic Analysis prices, Urban Honolulu ranks 8 and Kahului ranks 13, counting from the most expensive. The national median area sits at 93.492 — Monroe — so 2 of these 2 Hawaii areas are dearer than the typical American metropolitan area and 0 are cheaper.

Urban Honolulu is in the most expensive tenth of the country, which is worth knowing before reading its position in the state table as merely "the dear one".

The distinction matters for a specific reason. Everything on this page holds the income tax constant because these cities share a state; the moment a move crosses a state line that stops being true, and the comparison becomes the harder one — which is what Hawaii against every other state is for.

The tax that is the same in all 2

Worth spelling out, because it is what makes the ranking above readable at all. On $100,000, in every one of these areas:

Federal income tax — $13,170. Set by Congress, identical everywhere in the United States.

Social Security and Medicare — $7,650. Also federal, and also flat across the country up to the Social Security ceiling.

Hawaii income tax — $5,796. One set of brackets for the whole state, one standard deduction, applied identically in every city on this page.

Local income tax — $0. Hawaii does not permit counties, cities or school districts to levy their own. That is not a modelling shortcut, it is the law, and it is the condition on which these pages get published: in the eleven states that do permit it, the levying jurisdictions do not line up with metropolitan areas and no honest rate can be assigned.

Which leaves property tax as the only tax in the whole comparison that moves — from $672 to $1,137 a year on the same $400,000 home — and the price level as the only other thing. Two variables, both measured, both sourced. It is as clean as a cost-of-living comparison gets.

Kahului stays on top whether you rent or buy

A ranking built on one salary and one house value is worth exactly as much as its assumptions, so here are the same 2 areas resolved again with those assumptions changed.

Renting, with no property tax at all: Kahului still leads, by $948 over Urban Honolulu. The order does not depend on owning a house.

On $60,000 instead of $100,000: Kahului still leads. The gap narrows to $1,026 — smaller in dollars, but a larger share of a smaller salary.

On $250,000: Kahului still leads, and by $2,546 — the spread widens with income, because the price level applies to everything you have left after tax.

This is the same discipline applied to a single published figure elsewhere on this site: a number without its range is half a number. Every page linked above lets you set your own salary, your own house and your own horizon, and recomputes the whole comparison rather than scaling it.

How this is worked out, and what it does not claim

Every row is the same calculation: gross salary in, federal income tax and FICA out, Hawaii income tax out, property tax on a $400,000 home out — then what is left divided by that area's price level, so the figure is what the money buys rather than what the payslip says.

The price index is the Bureau of Economic Analysis Regional Price Parity, 2024, published per metropolitan area with a documented method and broken into housing, goods, utilities and services. Which counties make up each area comes from the Census Bureau delineation file, joined by CBSA code and never by name — there are thirty "Washington County" in the United States and a join on names would have failed silently.

What it does not claim: that the city at the top is the better place to live. This measures what a salary buys. Schools, the commute, the weather and how far you are from your family are not in it, and on a move inside one state they are usually what actually decides it.

It also assumes one salary, one house value and a buyer rather than a renter. Every page linked above lets you change all three, and the answer moves with them — on some pairs enough to change which city comes out ahead.

Where to go next

Questions

Which city in Hawaii leaves you best off?
Kahului, at $66,469 of purchasing power on $100,000 with a $400,000 home — $1,359 a year more than Urban Honolulu at the other end of the table. Because the income tax is identical everywhere in Hawaii, that ranking is made of two things only: the price level and property tax.
Which is the cheapest city in Hawaii?
Kahului, at 109.393 on the Bureau of Economic Analysis price index where 100 is the US average, against 110.961 in Urban Honolulu. Cheapest is not the same as best off, though: property tax is set separately and can move a household by $466 a year on the same house.
Does income tax differ between cities in Hawaii?
No. Hawaii sets one set of brackets for the whole state, and it does not let counties or cities levy their own income tax. On $100,000 the bill is federal $13,170, FICA $7,650 and state $5,796 in every one of these 2 areas. That is what makes comparing them clean.
How much does cost of living vary inside Hawaii?
Hawaii has 2 metropolitan areas, 109.393 and 110.961 on the price index. The spread is narrower than in a state like California, but the state-level figure is still an average of them rather than a description of either.
How many Hawaii city comparisons are there?
1, one page each, every pair of the 2 metropolitan areas the Bureau of Economic Analysis prices in Hawaii. Each resolves the same way — income tax, property tax and price level — and each shows the break-even salary in both directions.
