Adjusted monthly income is a term used primarily in federal housing assistance programs to determine how much rent you pay. It equals your household’s annual income, minus specific deductions allowed by HUD (the U.S. Department of Housing and Urban Development), divided by 12. This number directly sets your rent in programs like the Housing Choice Voucher (Section 8) program and public housing, so understanding how it works can help you anticipate what you’ll owe each month.
How Adjusted Monthly Income Is Calculated
The calculation starts with your annual gross income, which includes wages, Social Security benefits, pensions, and most other recurring income sources for everyone in your household. From that total, HUD subtracts a set of mandatory deductions to arrive at your “adjusted annual income.” Your adjusted monthly income is simply that adjusted annual figure divided by 12.
Your rent in most HUD programs is set at 30% of your adjusted monthly income. So every deduction you qualify for directly lowers the rent you pay. A family earning $24,000 a year with $2,000 in eligible deductions would have an adjusted annual income of $22,000, an adjusted monthly income of about $1,833, and a rent portion of roughly $550.
Deductions That Lower Your Adjusted Income
HUD allows several mandatory deductions before calculating what you owe in rent. For 2026, these are the key ones:
- Dependent deduction: $500 per year for each household member who qualifies as a dependent (typically children under 18 or full-time students).
- Elderly or disabled family deduction: $550 per year if the head of household, spouse, or sole member is 62 or older, or has a disability.
- Child care expenses: Reasonable costs you pay for child care that allow a household member to work, look for work, or attend school.
- Disability assistance expenses: Costs for attendant care or equipment that allow a disabled household member or another family member to work.
- Unreimbursed medical expenses: For elderly or disabled families, medical expenses that exceed a certain threshold can be deducted.
These deduction amounts are adjusted for inflation each year by HUD, so check the current figures when you apply or recertify.
Income That Doesn’t Count
Not every dollar your household receives counts toward gross annual income in the first place. HUD excludes a long list of income sources before you even get to the deductions. Some of the most common exclusions include:
- Student financial aid funded under Title IV of the Higher Education Act, including federal work-study earnings.
- Child care assistance received through the Child Care and Development Block Grant program.
- Disaster relief payments from FEMA or comparable state and local programs.
- Crime victim compensation received for medical or other assistance.
- Earned income of dependent full-time students beyond $500 per year (only the first $500 counts).
- Adoption assistance payments beyond $500 per year.
The full list of federally mandated exclusions is extensive, covering dozens of specific programs. Your housing authority will walk through which income sources apply during your eligibility interview, but knowing these exclusions exist means you won’t accidentally overestimate your own income when deciding whether to apply.
How Assets Factor In
If your household holds significant assets like savings accounts, investments, or real property, those can affect your income calculation. For 2026, if your net family assets exceed $52,787, your housing authority will calculate an “imputed return” on those assets using a passbook savings rate of 0.40% and add that figure to your annual income. Families with net assets above $105,574 are generally ineligible for housing assistance altogether.
If your net assets fall below $52,787, your housing authority can accept a simple self-certification rather than requiring bank statements and investment documentation, which speeds up the process.
Changes Under HOTMA
The Housing Opportunity Through Modernization Act (HOTMA) updated several rules governing how adjusted income is calculated. Housing authorities that have implemented HOTMA’s Sections 102 and 104 now use annually adjusted deduction amounts and asset thresholds tied to inflation, rather than the older static figures. The deduction and threshold numbers listed above reflect these inflation-adjusted 2026 values. If your local housing authority has not yet adopted HOTMA’s provisions, it may still use older deduction amounts, so the figures you encounter could differ slightly depending on where you live.
Adjusted Monthly Income vs. Other Income Measures
If you came across “adjusted monthly income” while applying for a mortgage or personal loan rather than housing assistance, the term you’re likely looking for is gross monthly income or adjusted gross income (AGI). These work differently from HUD’s definition.
Mortgage lenders typically use your gross monthly income, your total earnings before taxes, to calculate your debt-to-income ratio. A common guideline is spending no more than 28% of gross monthly income on housing costs and no more than 36% on all debt combined. Lenders may also look at your AGI from your tax return, which is your gross income minus IRS-allowed deductions like retirement contributions and student loan interest. Neither of these is the same as HUD’s adjusted monthly income, which uses its own set of deductions specific to housing assistance.
If you’re dealing with a housing authority or applying for rental assistance, adjusted monthly income refers to the HUD calculation described above. If you’re applying for a loan, your lender will tell you exactly which income figure they need, and it will almost certainly be gross income or AGI rather than the HUD version.
