Section 8 does not pay a set monthly amount. Under the Housing Choice Voucher Program, how much rent Section 8 pays per month is the gap between your local payment standard (or the actual gross rent, whichever is lower) and your tenant share, which for most families works out to about 30 percent of adjusted monthly income. If the payment standard for your voucher size is $1,600 and your share is $575, the subsidy sent to your landlord is $1,025 that month.
The Formula Your Housing Agency Uses
The monthly check your housing agency sends the landlord is called the Housing Assistance Payment. The agency compares two numbers, uses the lower one, and subtracts your share. The payment equals the lesser of the local payment standard for your voucher size or the actual gross rent on the unit, minus your Total Tenant Payment.1eCFR. 24 CFR 982.505 – How To Calculate Housing Assistance Payment
A worked example makes it concrete. Say the payment standard in your area for a two-bedroom is $1,600 and your Total Tenant Payment is $575. If you rent a unit with a gross rent of $1,700, the agency uses the $1,600 payment standard because it is lower. Your subsidy is $1,600 minus $575, or $1,025. You pay the landlord the remaining $675 out of pocket ($1,700 gross rent minus the $1,025 subsidy).
Now flip the numbers. If you find a unit with a gross rent of $1,400, below the payment standard, the agency uses the $1,400 figure. Your subsidy drops to $1,400 minus $575, or $825. Your share stays $575 either way. Picking a less expensive unit does not increase your subsidy; it just lowers the total.1eCFR. 24 CFR 982.505 – How To Calculate Housing Assistance Payment
How Your Share Is Calculated
The Total Tenant Payment is the amount you contribute each month. Federal rules set it at the highest of four figures: 30 percent of your monthly adjusted income, 10 percent of your monthly gross income, any welfare housing assistance you receive, or a minimum rent your agency sets.2eCFR. 24 CFR 5.628 – Total Tenant Payment For most families the 30 percent figure comes out on top, so that is what they pay.
Adjusted Income, Not Gross Income
Adjusted income begins with your household’s gross annual income and then subtracts specific deductions. For 2026, HUD sets the mandatory dependent deduction at $500 per dependent and the deduction for elderly or disabled households at $550.3HUD User. 2026 HUD Inflation-Adjusted Values Additional deductions cover certain childcare costs, medical expenses for elderly or disabled families, and disability-related assistance expenses.
Take a family earning $2,000 per month ($24,000 annually) with two dependents. Two dependent deductions of $500 each reduce annual income to $23,000, or about $1,917 per month. Thirty percent of that is roughly $575, which becomes their Total Tenant Payment.
Income That Does Not Count
Several types of money are left out of the calculation entirely. Foster care payments, earned income of children under 18, financial aid used for tuition and required school expenses, and one-time payments like insurance settlements or tax refunds are excluded.4eCFR. 24 CFR 5.609 – Annual Income Distributions from 529 college savings plans and Coverdell education savings accounts are excluded too. If a live-in aide resides with you to help a disabled family member, that aide’s income is not counted.
The Payment Standard Where You Live
The payment standard is the ceiling your agency will pay toward rent for a given voucher size. It is anchored to Fair Market Rent, an estimate HUD publishes each year for the cost of renting modest, non-luxury housing with basic amenities in a specific area. FMRs take effect every October 1 and are set at the 40th percentile of local rents, meaning roughly 40 percent of standard rental units in the area could be rented at or below that figure.5eCFR. 24 CFR Part 888 Subpart A – Fair Market Rents
Your local housing agency then sets its own payment standard schedule. It must fall between 90 and 110 percent of the published FMR for each unit size. Anything above 110 percent needs a special exception from HUD.6eCFR. 24 CFR 982.503 – Payment Standard Areas, Schedule, and Amounts If the FMR for a two-bedroom is $1,500, the agency can set its payment standard anywhere from $1,350 to $1,650 without special permission. That range explains why the same household size can see very different subsidy amounts depending on which agency issued the voucher.
Small Area Fair Market Rents
Standard FMRs cover an entire metropolitan area, which can hide large rent differences between neighborhoods. HUD allows, and in 65 metro areas requires, agencies to use Small Area Fair Market Rents calculated at the ZIP-code level.7U.S. Department of Housing and Urban Development (HUD). Small Area Fair Market Rents In those areas, a voucher holder searching in a higher-cost ZIP receives a larger payment standard than one searching in a lower-cost ZIP.
Voucher Size Sets the Ceiling
Your agency assigns a voucher size in bedrooms based on household composition. The general rule is one bedroom for every two people, though agencies have some flexibility. A family of four usually receives a two-bedroom voucher.8eCFR. 24 CFR Part 982 – Section 8 Tenant-Based Assistance: Housing Choice Voucher Program – Section 982.402
You can rent a unit larger or smaller than your voucher size, as long as it meets occupancy standards and passes inspection. The subsidy uses the payment standard for your voucher size or the actual unit size, whichever is lower. A family with a two-bedroom voucher renting a three-bedroom house still has its subsidy calculated using the two-bedroom payment standard, and the family absorbs the extra cost.
If a family member has a disability that requires a live-in aide, the agency generally must count that aide when setting voucher size, which can raise both the voucher size and the payment standard. Requests for a larger voucher based on medical needs typically require written documentation from a healthcare provider.
Utilities Change the Math
Gross rent is not just what you pay the landlord. It includes the estimated cost of tenant-paid utilities. Your agency publishes a utility allowance schedule for heat, electricity, water, and trash removal based on unit size and local rates. When it runs the subsidy calculation, it adds the utility allowance to the contract rent to arrive at gross rent.
The utility allowance works as a credit against your share. If your Total Tenant Payment is $575 and the utility allowance is $125, only $450 goes to the landlord. You use the remaining $125 of your share to pay utility bills directly. The agency pays the landlord the difference between the contract rent and your $450.
When the Allowance Exceeds Your Share
For very low-income households, the utility allowance can be larger than the Total Tenant Payment. When that happens, the agency owes you a utility reimbursement for the difference. It can send that payment to you directly or straight to the utility company on your behalf.9eCFR. 24 CFR 5.632 – Utility Reimbursements If you leave the program between scheduled reimbursement dates, the agency must send you a prorated share for the period you were still enrolled.
If You Have Little or No Income
Even with no income, your agency can require a minimum monthly rent of up to $50. The exact amount varies by agency, but federal law caps it at that level.10Office of the Law Revision Counsel. 42 USC 1437a – Rental Payments The minimum rent includes any amount allocated for utilities, so it covers your entire housing cost obligation rather than sitting on top of utility payments.
If even $50 is out of reach, you can request a hardship exemption. The agency must grant one when specific hardships exist, including:
- Loss of benefits: You have lost eligibility for or are waiting on a determination for a federal, state, or local assistance program.
- Eviction risk: You would be evicted because you cannot pay the minimum rent.
- Income drop: Your income has dropped due to changed circumstances such as job loss.
- Death in the family: A family member has passed away, affecting household income.
Agencies may also grant exemptions for other circumstances at their discretion.11eCFR. 24 CFR 5.630 – Minimum Rent During the review period, the agency must suspend the minimum rent. If approved, the suspension lasts as long as the hardship does.
The 40 Percent Cap at Move-In
When you first move into a unit with a gross rent above the payment standard, your agency cannot approve the lease if your share would exceed 40 percent of your adjusted monthly income.12eCFR. 24 CFR Part 982 Subpart K – Rent and Housing Assistance Payment – Section 982.508 This cap applies only at initial lease-up. After you have been in the unit, your rent burden can drift above 40 percent if your income drops or the landlord raises the rent, but the agency will not approve a new tenancy that starts above the threshold. The income verification used for this determination must be no more than 60 days old when the agency issues your voucher.
How the Amount Can Change Over Time
Your subsidy is not fixed once you move in. Your agency reviews your income and household composition at least once a year through annual recertification, and you provide updated documentation.13eCFR. 24 CFR 982.516 – Family Income and Composition: Annual and Interim Reexaminations
Between annual reviews, you can request an interim recertification if your income drops significantly, which lowers your share before the next scheduled review. If your agency learns your income has increased by 10 percent or more, it may conduct an interim review on its own and raise your share. If you fail to report an income increase in a timely manner, the agency can apply the rent increase retroactively to the month the change occurred.13eCFR. 24 CFR 982.516 – Family Income and Composition: Annual and Interim Reexaminations
Moving to another area also changes the number. Vouchers are portable, and if you relocate to a jurisdiction served by a different housing agency, your payment standard shifts to that area’s rates.14HUD.gov. Housing Choice Voucher Program Guidebook – Moves and Portability A move from a low-cost market to a high-cost one can raise the subsidy substantially; a move in the other direction can reduce it. Your income eligibility is not re-tested during a portability move if you are already an active participant, but the dollar amount your voucher pays each month will be recalculated using the new area’s payment standard.
