Different rules, different numbers

Each heuristic produces a slightly different cap. The right answer is the lowest of the rules that matter to you.

30% of gross income (classic)

Works best in no-income-tax states. Too generous in CA/NY.

$1,875/mo

40x rule (landlord approval)

What most property managers will actually approve.

$1,875/mo

30% of net income

More honest in high-tax states — this is your real constraint.

$1,384/mo

35% of net minus existing debts

DTI-aware. If you have student loans / car payment.

$1,114/mo

Informational only.

Tax estimates use 2026 federal brackets + standard deduction, state top/flat rate as blended approximation, and 2026 FICA rates. Actual take-home depends on 401(k) contributions, health insurance, HSA, itemized deductions, and local taxes (NYC adds 3.876%). Use this for planning.
