How Much Does a Car Really Cost in Honolulu, Hawaii?

Honolulu figures checked October 27, 2026

The answer up front

For a worked example, use a 2026 Ford F-150 XLT SuperCrew 4x4 at $51,090, the truck America buys more than any other new vehicle. Over five years in Honolulu, it runs $67,011, or about $1,117 a month. The loan payment alone is $981 a month. The six buckets:

• Value lost: $19,721 ($51,090 minus $31,369 resale)
• Insurance: $8,800 ($1,760 a year x 5 years)
• Fuel: $15,943 (12,000 / 21 x $5.58 x 5 years)
• Maintenance: $7,000 ($1,400 x 5 years)
• Tax, fees and interest: $12,908 ($2,407 general excise tax passed on, $17 fees, $10,484 loan interest)
• Weight tax, base fees and inspections: $2,639 ($2,229 weight tax, $333 base fees, $77 inspections)

The state figures on this page match the Hawaii state door, which this city page builds on: the same up to 4.712% passed-on general excise tax, the same weight-tax formula, the same $66.50 a year in base fees. What changes for Honolulu is the city-level part, insurance at the Honolulu rate, gas at the Honolulu metro average, and the county weight-tax rate at the Honolulu figure.

Day one: the general excise tax, passed on

Hawaii has no regular sales tax. Dealers pay the general excise tax and almost always pass it on, at up to 4.712% of price (4% state plus a 0.5% county surcharge, grossed up for tax on the tax). On the $51,090 example, the passed-on tax is $2,407. Private sales between individuals are generally not taxed the same way, so a private-party purchase would look different on this line.

The bill that comes back every year: weight tax by the pound

Hawaii weight tax has two parts. The state tax (Hawaii Revised Statutes section 249-33) runs 1.75 cents per pound up to 4,000 pounds net weight, 2.00 cents per pound from 4,001 to 7,000 pounds, 2.25 cents per pound from 7,001 to 10,000 pounds, and a flat $300 over 10,000 pounds. The Honolulu County weight tax is 7.0 cents per pound at all weights, from the state door, the county table, and a relocation guide that confirms 8.75 cents combined for a 4,000-pound vehicle. One conflict is noted and resolved, not hidden: a secondary guide listing Honolulu County at 1.75 cents conflicts with the state door and the other sources and must not be used. Hawaii taxes net weight, not gross vehicle weight rating, so this page uses the dealer base curb weight of 4,953 pounds as the net-weight proxy, the same kind of proxy the state door used with a 4,500-pound Tacoma weight, and it does not use the 6,650-pound gross rating. At 4,953 pounds, the state tax is $99.06 a year and the county tax is $346.71 a year, for $445.77 a year, or $2,229 over five years, rounded.

Base fees of $66.50 a year, or $333 over five years, rounded from $332.50, are carried from the state door. Their itemization was not re-verified for the F-150 weight band: other guides list components that do not sum cleanly to $66.50, so this page keeps the state door figure for consistency and says so. Safety inspections at $25.75 each, with new vehicles exempt for the first two years after first sale, mean three inspections in the five-year example, or $77. The registration bucket is $2,639. Against the state door Tacoma bucket of $2,435, the increase is entirely the heavier F-150 weight tax.

Title and plates: the smaller stack

The one-time fees are $17, carried from the state door Tacoma example. Their components were not re-verified for Honolulu and the F-150: guides list a $5 title fee for new registrations or $10 for a transfer. The $17 sits in the tax, fees and interest bucket, and the $5 title fee must not be double-counted if it is already inside the $66.50 a year base fees, which is the second caveat on this page.

Emissions tests and safety inspections

There is no smog test anywhere in Hawaii, so emissions cost $0. Safety inspections cost $25.75 each, with new vehicles exempt for the first two years, so this example includes three inspections at $77 over five years, inside the registration bucket above.

Insurance: the Honolulu figure, the lowest in this batch

Full-coverage insurance, insurance that covers damage to your own car, not just damage you cause to others, averages about $1,760 a year in Honolulu, or $147 a month, for a benchmark 40-year-old driver with a clean record, from rates insurers filed with state regulators as of August 31, 2026. The example uses that figure, or $8,800 over five years. Second sources corroborate closely: Insure.com at $1,710 a year and autoinsurance.com at $1,705 a year. Your own quote is what matters.

Gas: the Honolulu metro price, dated

Gas here is a snapshot, not a five-year promise: the AAA Honolulu average was $5.58 a gallon for regular on October 22, 2026, from the AAA Hawaii Weekend Gas Watch, against a Hawaii statewide average near $5.64. That October 22 figure is the latest Honolulu metro figure found, and it is labelled as such, not as an October 27 figure. For a truck driving 12,000 miles a year at 21 mpg, that is 571.4 gallons a year, or $15,943 over five years at the snapshot price. Gas prices move weekly, so re-run this line at your local price.

A full Honolulu example: a 2026 F-150 XLT SuperCrew 4x4

The example truck is built from verified pieces: XLT starting price $44,695, four-wheel drive typically adding $3,800, plus the $2,595 destination charge, for $51,090 before tax, registration, and options. Same loan pattern as the other city pages: 10% down ($5,109), 8% APR (the yearly interest rate on the loan), 60 months. The financed amount, price plus tax plus fees minus the down payment, is $51,090 + $2,407 + $17 − $5,109 = $48,405, which works out to $981 a month on the loan, with $10,484 of interest over five years. Resale comes from iSeeCars: the F-150 loses 38.6% of its value over five years on the model own page, so the truck is worth $31,369 after five years and depreciation is $19,721.

• Value lost: $19,721 ($51,090 minus $31,369 resale)
• Insurance: $8,800 ($1,760 a year x 5 years)
• Fuel: $15,943 (12,000 / 21 x $5.58 x 5 years)
• Maintenance: $7,000 ($1,400 x 5 years)
• Tax, fees and interest: $12,908 ($2,407 general excise tax passed on, $17 fees, $10,484 loan interest)
• Weight tax, base fees and inspections: $2,639 ($2,229 weight tax, $333 base fees, $77 inspections)

That totals $67,011 over five years, or about $1,117 a month. The Honolulu pattern in one sentence: the day-one tax is low for a coastal city, the weight tax bills by the pound every year, insurance is the lowest in this batch, and fuel at island prices is the line that keeps the total from falling further.

Formula

The five-year total is the sum of six buckets: value lost, insurance, fuel, maintenance, tax, fees and interest, and weight tax, base fees and inspections. Value lost is the $51,090 price minus the $31,369 resale value after five years, which is $19,721. Insurance is $1,760 a year times 5 years, which is $8,800. Fuel is 12,000 miles a year divided by 21 miles per gallon, times $5.58 a gallon, times 5 years, which is $15,943. Maintenance is $1,400 a year times 5 years, which is $7,000. Tax, fees and interest is $2,407 of general excise tax passed on, $17 in fees, and $10,484 of loan interest, which is $12,908. Weight tax, base fees and inspections is $2,639 over five years: $2,229 of weight tax, $333 of base fees, and $77 of inspections.

Added together, $19,721 plus $8,800 plus $15,943 plus $7,000 plus $12,908 plus $2,639 equals $67,011, or about $1,117 a month. The financed amount is the $51,090 price plus $2,407 of tax plus $17 in fees, minus the $5,109 down payment, which is $48,405. At 8% APR over 60 months, the payment on $48,405 is $981 a month, and the loan costs $10,484 in interest over five years.

Definitions

General excise tax. The tax dealers pay on their gross income, which they almost always pass on to the buyer, at up to 4.712% of price, 4% state plus a 0.5% county surcharge, grossed up for tax on the tax. On the $51,090 example, the passed-on tax is $2,407. Private sales between individuals are generally not taxed the same way.

Weight tax. Hawaii's yearly registration charge by the pound, in two parts. The state tax runs 1.75 cents per pound up to 4,000 pounds net weight, 2.00 cents per pound from 4,001 to 7,000 pounds, 2.25 cents per pound from 7,001 to 10,000 pounds, and a flat $300 over 10,000 pounds. The Honolulu County weight tax is 7.0 cents per pound at all weights.

Net weight. The weight the weight tax is figured on. Hawaii taxes net weight, not gross vehicle weight rating, so this page uses the dealer base curb weight of 4,953 pounds as the net-weight proxy. At 4,953 pounds, the state tax is $99.06 a year and the county tax is $346.71 a year, for $445.77 a year, or $2,229 over five years, rounded.

Gross vehicle weight rating. The truck's rated maximum loaded weight, 6,650 pounds for the example truck. Hawaii taxes net weight, not this rating, so the rating is not used in the weight tax math.

Base fees. The flat yearly fees of $66.50 a year, or $333 over five years, rounded from $332.50, carried from the state door. Their itemization was not re-verified for the F-150 weight band.

Title fee. The one-time fee to put the car in your name. The one-time fees are $17, carried from the state door, and guides list a $5 title fee for new registrations or $10 for a transfer. The $17 sits in the tax, fees and interest bucket.

Safety inspection. The yearly safety check, which Hawaii requires, and which you need current before you can renew registration. Inspections cost $25.75 each, with new vehicles exempt for the first two years, so this example includes three inspections at $77 over five years. There is no smog test anywhere in Hawaii, so emissions cost $0.

Full-coverage insurance. Insurance that covers damage to your own car, not just damage you cause to others. In Honolulu it averages about $1,760 a year, or $147 a month, for a benchmark 40-year-old driver with a clean record, from rates insurers filed with state regulators as of August 31, 2026.

APR. Annual percentage rate, the yearly interest rate on the loan. This example uses 8%. For context, Experian reported average rates of 6.35% on new cars and 11.19% on used cars in the second quarter of 2026.

Depreciation. The value the car loses over time. On this page, the $51,090 price minus the $31,369 resale value after five years, which is $19,721.

Figures from the Hawaii state door (Hawaii Revised Statutes sections 249-1 and 249-33 for net weight and the weight-tax bands, Honolulu County 7.0-cent rate, $66.50 a year base fees, $17 one-time fees, $25.75 safety inspections), AAA Honolulu gas average (October 22, 2026, the latest Honolulu metro figure found), filed-rate insurance data as of August 31, 2026, and iSeeCars F-150 depreciation. Insurance quotes, gas prices, and dealer charges vary by driver, car, and dealer, the structure above is the part that does not change. Two caveats are disclosed on the page: the county weight-rate conflict was resolved to 7.0 cents against a conflicting 1.75-cent guide, and the base-fee breakdown and $17 one-time figure are carried from the state door Tacoma example, not re-verified item by item for the F-150.
