Is the 30% rule still realistic?

In many high-cost cities, renters spend 35–50% of income on rent. The 30% guideline is a target, not a hard rule. Spending under 30% allows more savings and financial flexibility.

Should I use gross or net income?

The 30% rule traditionally uses gross (pre-tax) income. Some advisors recommend using net (take-home) income for a more conservative estimate, particularly for high earners in high-tax jurisdictions.

What other housing costs should I factor in?

Add renters insurance (~$15–30/month), utilities (varies widely), parking, and any pet fees to get your true housing cost when comparing apartments.

What if I can't find housing under 30%?

Consider roommates to split costs, look in nearby neighborhoods, commute from a lower-cost area, or increase income through a raise or side income before signing a lease.

How does this differ from the 28/36 rule?

The 28/36 rule is mainly used for mortgage qualification. The 30% guideline is specifically for renters and is slightly more flexible. Both are rules of thumb, not financial law.

How to use it

1️⃣ Enter your monthly gross income (before taxes).
2️⃣ Enter your existing monthly debt payments (car, student loans, credit cards, etc.).

Formula

Max rent (30% rule) = monthly income × 0.30. Adjusted max = monthly income × 0.30 − monthly debts. Comfortable range = 25–30% of monthly income after debts.

💡 See it in action — a real example

Monthly income of $5,000 with $400/month in debts: Max at 30% = $1,500. Adjusted = $1,500 − $400 = $1,100. Comfortable range: $850–$1,100/month.
