What is the 30% rent rule?

The guideline says housing should cost no more than 30% of gross income. Spending above that level classifies a household as cost-burdened, which is common across Honolulu.

Is Honolulu rent affordable on a typical income?

Often not. With a median 1-BR around $2,200, you generally need about $7,300 in monthly gross income to keep rent under the 30% threshold.

Should I use gross or net income?

The classic 30% rule uses gross (pre-tax) income. The calculator follows that convention, so enter your salary before deductions.

What if my ratio is above 30%?

Between 30% and 50% you are cost-burdened; above 50% you are severely cost-burdened. Consider a roommate, a smaller unit, or a neighborhood farther from Waikiki to lower the ratio.

Does this include utilities?

No. The 30% rule covers rent only. Budget separately for Hawaii's high electricity costs, internet, and renters insurance.

Check your Honolulu rent affordability

Honolulu has some of the highest rents in the country, so the classic 30%-of-income rule matters here more than almost anywhere. This tool compares your rent against your income and against the local median 1-BR rent of $2,200, then tells you whether the lease is affordable.

How it works

The calculator computes the share of your income that goes to rent and the maximum rent the 30% guideline allows:

monthly income = annual / 12 (or your monthly figure directly)
ratio          = rent / monthly income
max rent       = monthly income * 0.30

The verdict follows HUD-style thresholds: at or below 30% is affordable, 30% to 50% is cost-burdened, and above 50% is severely cost-burdened.

Tips and example

If you earn $6,500/mo and the rent is $2,200, your ratio is 2200 / 6500 = 33.8% — just over the line, so you are mildly cost-burdened. To stay within 30%, your rent should be at most 6500 * 0.30 = $1,950.

Because Honolulu rents are high, many residents share housing or accept a higher ratio. Use the verdict as a planning signal, and remember to leave room for Hawaii’s steep utility bills.
