💵 Comfortable Income Calculator by ZIP Code

Enter any U.S. ZIP code and see the annual income needed to live comfortably there — based on real U.S. Census median rent data and the classic 30% housing rule. Get both single-adult and family-of-3–4 benchmarks in seconds. No account, no ads inside the tool, no data collected.

Run the numbers

How the math works

Nearly every "comfortable salary" figure you'll see for U.S. cities traces back to one budgeting benchmark: housing should cost no more than 30% of your gross income. This calculator inverts the rule — starting from a ZIP's actual median rent (real Census data, not listing-site prices), we work out the income at which that rent equals 30% of pay.

Family income uses a 1.85× multiplier on the single-adult figure, consistent with MIT Living Wage Calculator research and other cost-of-living studies for a household of three to four with one to two working adults. It accounts for larger housing needs, childcare, food, healthcare, and transportation for additional people.

Why ZIP-level beats city-wide numbers

Most viral "salary needed to live in [city]" headlines use a single metro-wide average — but rent inside one city can vary by more than 2× between ZIP codes. A one-number-per-city figure is wrong almost everywhere: too high for most of the metro, too low for the neighborhoods people are usually asking about. This calculator uses the real number for your specific ZIP.

What the calculator does and doesn't tell you

Benchmark, not a minimum. Millions of households live below their ZIP's benchmark. "Comfortable" here means housing isn't straining the budget.
Assumes renting. Owners should mentally swap in monthly ownership cost (mortgage + taxes + insurance) for rent.
Doesn't see your debt. Student loans or car payments effectively raise your personal number.
Doesn't see your life. Remote work, roommates, family childcare — no formula captures everything. Use the result as a comparison tool between places.
