How much is a monthly mortgage payment in Hawaii?
Here's a worked example for Hawaii. On a $400,000 home with 20% down ($80,000), you'd borrow $320,000. At a 6.55% 30-year fixed rate — the current U.S. national average — the principal and interest come to about $2,033 per month. Adding Hawaii's average effective property tax of 0.29% ($1,160 a year, or $97 a month) brings the core housing cost to roughly $2,130 per month, before home insurance and any HOA dues. Enter your own price, down payment, and rate in the calculator above to get your exact number.
Property taxes in Hawaii
Hawaii's average effective property-tax rate is 0.29%, which is below the U.S. average of 0.90% and ranks among the lower of all states. On the $400,000 example home that's $1,160 per year. Rates are set locally, so your actual county or city rate can differ — check your county assessor's site and adjust the property-tax field above to match.
What changes your payment in Hawaii
- Down payment. Under 20% down usually adds private mortgage insurance (PMI), raising your monthly cost until you build enough equity.
- Your rate. The 6.55% above is a national average — shopping two or three lenders often beats it, and even 0.25% changes the payment noticeably.
- Local property tax. The 0.29% used here is a statewide average; your specific county or municipality may be higher or lower.
- Home insurance. Premiums vary widely by location and risk — get a real quote and enter it in the calculator for an accurate total.
- HOA or condo dues. If your property has them, add the monthly amount to see your true all-in housing cost.
How much house can you afford in Hawaii?
A common lender guideline is the 28% rule: keep your total monthly housing payment at or under 28% of your gross (pre-tax) monthly income. Here's what that works out to at a few income levels in Hawaii, assuming a 6.55% 30-year fixed rate, 20% down, and Hawaii's 0.29% average property-tax rate. The affordable price is a starting estimate before home insurance, HOA dues, and other debts — all of which lower it.
| Gross annual income | Max monthly payment (28%) | Est. affordable home price |
|---|---|---|
| $75,000 | $1,750 | $329,000 |
| $100,000 | $2,333 | $438,000 |
| $150,000 | $3,500 | $657,000 |
| $200,000 | $4,667 | $876,000 |
These are illustrative estimates using the 28% front-end guideline and Hawaii's statewide average property-tax rate — your real number depends on your down payment, credit, other monthly debts (the broader 36% back-end rule), insurance, and your exact county rate.

Conforming loan limits in Hawaii — when you cross into jumbo
A conforming loan is one Fannie Mae or Freddie Mac will buy, which is what keeps rates and underwriting relatively standard. Borrow above the limit for your county and you're in jumbo territory — usually a larger deposit, tighter credit requirements, and a different rate. For 2026 the national baseline is $832,750, and the limit is set county by county, not state by state.
Hawaii is unusual: every one of its 5 counties carries a limit above the national baseline, up to $1,299,500. Statutorily higher limits apply across the whole state, so the jumbo threshold sits well above what buyers in most of the country face.
| County | 2026 one-unit limit |
|---|---|
| Kalawao County | $1,299,500 |
| Maui County | $1,299,500 |
| Hawaii County | $1,249,125 |
| Honolulu County | $1,249,125 |
| Kauai County | $1,249,125 |

Frequently asked questions
How is my monthly mortgage payment calculated?
Your total monthly payment is principal and interest (calculated with the standard fixed-rate amortization formula) plus 1/12 of your annual property tax, 1/12 of your annual home insurance, and any monthly HOA/strata/service charge. Adjust any of the inputs above to see how each one changes your total.
What down payment do I actually need?
20% avoids private mortgage insurance (PMI) on a conventional loan, but many buyers put down less — some loan programs allow as little as 3–3.5%. A smaller down payment means a larger loan and a higher monthly payment, which you can see directly by changing the down payment field above.
What does the affordability verdict mean?
It uses the standard 28/36 front-end debt-to-income guideline that most lenders reference: a payment at or under 28% of your gross monthly income is considered comfortable, 28–36% is a stretch worth budgeting carefully for, and over 36% is tight by most lenders’ standards. Enter your gross monthly income to see your own number.
Is property tax the same everywhere in Hawaii?
No — property tax rates vary by county and even by city within Hawaii. The calculator starts from Hawaii's statewide average effective rate of 0.29%, so check your local assessor's site for your exact county rate and adjust the field to match.
