1. What is the NYC 40x Rule?

The NYC 40x rule is a standard used by landlords to determine if a tenant's income is sufficient to afford the rent. The rule states that a tenant's annual income should be at least 40 times the monthly rent, adjusted for apartment size factors in different neighborhoods.

2. How Does the Calculator Work?

The calculator uses the adjusted 40x formula:

Where:

• Monthly Rent — The apartment's monthly rent in USD
• Apartment Size Factor — Adjustment factor based on neighborhood and apartment size (typically 0.8-1.2)

Explanation: The standard 40x rule is adjusted by dividing by a size factor that accounts for neighborhood desirability and apartment size.

3. Importance of the 40x Rule

Details: This calculation is crucial for NYC renters to understand income requirements before apartment hunting, and for landlords to screen potential tenants.

4. Using the Calculator

Tips: Enter monthly rent in USD and the appropriate size factor (1.0 for standard, higher for smaller units in desirable areas, lower for larger units in less desirable areas).
