What Is Rent Burden?
Rent burden is the percentage of a household's income that goes toward rent. A household is considered "rent-burdened" when housing costs exceed 30% of gross income, and "severely rent-burdened" when costs exceed 50% of gross income.
The 30% threshold comes from the U.S. Department of Housing and Urban Development, which established it in 1981 as the standard for affordable housing. Before 1981, the benchmark was 25%.
AffordMap calculates rent burden using take-home pay rather than gross income, because take-home is what actually hits your bank account. A 30% gross-income threshold translates to roughly 38-42% of take-home pay depending on tax situation. On AffordMap salary pages, when we show "rent is X% of take-home," we're using the after-tax figure because it's more reflective of what you actually experience.
Nationally, about 46% of all renters are rent-burdened (paying more than 30% of income toward rent). In expensive metros like Miami, Los Angeles, and New York, the share exceeds 55%. The rent-burden rate has been increasing steadily since 2000 as housing costs have outpaced wage growth in most markets.
Rent burden is the single strongest predictor of financial stress for working households. Households paying more than 50% of income toward rent have essentially no buffer for emergencies, savings, or unexpected expenses.
Example
A teacher earning $53,000 in Miami takes home about $3,500/month after taxes. A 2-bedroom apartment at FMR ($1,900) consumes 54% of take-home pay, severely rent-burdened. The same teacher in Indianapolis takes home $3,600/month and pays $1,150 rent, 32% of take-home, just above the guideline.
