섹션 1: 연산 메커니즘

이 계산의 원리 (알기 쉬운 설명)

The standard 30% rule dictates that rent should not exceed 30% of your gross monthly income. However, if you carry substantial student loans, auto payments, or credit card debt, spending 30% on rent leaves you cash-starved. This tool applies the mortgage underwriting 28/36 rule: total monthly debt plus housing obligations should not exceed 36% of gross income.

Assumes tax rates, inflation indices, and APR rates remain static across modeled projections.
Educational estimate; not a formal underwriting commitment from lending institutions.
Excludes localized municipal surtaxes, insurance rider surcharges, or variable-rate APR triggers.

자주 묻는 질문

자주 묻는 질문: 적정 월세 계산기

What is the "40x Rule" used by NYC and large city landlords?

Many landlords require your annual gross salary to be at least 40 times the monthly rent. For a $2,000/month apartment, you need a minimum salary of $80,000 ($2,000 × 40). This is equivalent to spending 30% of your gross income on rent.

What should I do if rent in my city exceeds 30% of my income?

In ultra-competitive rental markets, take on a roommate to split fixed bedroom costs, look along transit corridors outside city centers, or negotiate for included parking and utilities.
