Amounts are rounded to the dollar, so lines may not add up exactly. The out-the-door price is what the car costs with tax and fees; the balance is what is left to pay or finance once your trade-in is settled. Anything marked not included has no single published amount, so add it from your dealer's offer sheet.

Hawaii is not in our cost ranking because a fee has no published starting amount. Compare every state.

What to check on your dealer's offer sheet

  • Hawaii sets no dollar cap on doc fees, so ask each dealer for theirs and compare.
  • Tax should be figured after subtracting your trade-in.
  • A manufacturer rebate generally comes off after tax is figured.
  • The title fee varies, but expect at least $5.00 for a newer car.

Hawaii out-the-door price: common questions

Is there a limit on dealer doc fees in Hawaii?

No. Hawaii sets no dollar cap on dealer documentation fees, so they vary from dealer to dealer. Ask for the doc fee in writing and compare it between dealers.

What is added to the price of a car in Hawaii?

On a $30,000 car bought from a dealer: sales tax of $1,350, the dealer's doc fee, title from $5 and registration (no single published amount). Any other dealer charges come on top.

How does a trade-in with a loan on it change what you pay in Hawaii?

On a $30,000 car the out-the-door price is about $31,355, before any fees we cannot price. A $10,000 trade-in with $4,000 still owed gives you $6,000 of trade-in equity, which comes off what is left to pay: about $24,905. Because Hawaii taxes the price after the trade-in, the tax drops too, so the out-the-door price itself falls to about $30,905.

How we calculate this

Out-the-door price = selling price + tax + doc fee + title + registration + other fees − rebate. Trade-in equity = trade-in value − loan still owed on it. Balance after trade-in = out-the-door price − trade-in equity. Tax follows Hawaii's rules for trade-ins, rebates and doc fees. Where a fee varies, we start from the lowest published amount. An empty fee field counts as $0, and the calculator lists it as still to add.
