The 3 Rules of Renting
When deciding how much rent you can afford, landlords looks at one number, but you should look at three:
1. The Landlord's Rule (40x Rule)
Most landlords require your annual income to be at least 40 times the monthly rent. This is mathematically the same as ensuring rent is no more than 30% of your gross income.
2. The 30% Rule
The standard advice: Spend no more than 30% of your gross income on housing. This is a good baseline but can be dangerous if you have high student loans or debt.
3. The 36% DTI Rule (Recommended)
This is what our calculator primarily uses. Your total Debt-to-Income (rent + car payments + loans) should not exceed 36% of your Gross Income. This ensures you aren't overleveraged.
Tip: If you live in a high-cost city (NYC, London, SF), these rules often stretch to 40-50%. If so, you must cut back on other "Wants" to compensate.
