The 30% rule
The most common guideline is to spend no more than 30% of your gross income on rent. It comes from U.S. federal housing policy: households paying more than 30% of income for housing are considered "cost-burdened" by HUD, and more than 50% "severely cost-burdened". CMHC in Canada uses the same 30% benchmark (shelter costs including utilities). On a $65,000 salary, 30% is $1,625 a month.
The 40× rule landlords use
Many landlords and property managers — especially in New York, Toronto and other expensive cities — require your annual income to be at least 40 times the monthly rent (some use 3× monthly income). On $65,000 a year, that allows rent up to $1,625. If you don't meet it, landlords may ask for a guarantor or a larger deposit (where legally allowed).
A budget-based approach
The 30% rule ignores taxes and debt. If you have student loans or a car payment, 30% of gross income can be too much. This calculator also builds a budget from your take-home pay: it subtracts your debt payments, utilities and a savings goal, and leaves a reasonable share for food, transportation and other needs, similar to the popular 50/30/20 budget (50% needs, 30% wants, 20% savings). The recommended maximum is the lowest of the three methods.
Costs to plan for beyond rent
- Security deposit and first (sometimes last) month's rent. Deposit limits vary by state; in Ontario landlords may only collect last month's rent, not a damage deposit.
- Utilities, internet, renter's insurance, parking and laundry.
- Application fees and moving costs.
