TL;DR
Section 8 (the Housing Choice Voucher program) pays the gap between 30% of your adjusted monthly income and the local payment standard set by your housing authority. In practice, vouchers cover roughly 70 to 100% of rent for very low-income households. The exact dollar amount depends on your income, family size, bedroom size, and where you live.
What is the basic formula Section 8 uses to calculate your share?
The core math is simple. Voucher holders pay the greater of 30% of adjusted monthly income or 10% of gross monthly income toward rent and utilities [1]. Your housing authority sets a payment standard, which is the most it will pay toward a unit of a given bedroom size in your area. The voucher covers the gap between your required contribution and that standard.
Here is a concrete example. Say your adjusted monthly income is $1,200 and the payment standard for a two-bedroom in your city is $1,500. Your required share is 30% of $1,200, which is $360. The housing authority pays the remaining $1,140 directly to the landlord.
Two things can change that. If the actual rent is below the payment standard, your share stays the same and the authority simply pays less. If you pick a unit above the payment standard, you pay the extra on top of your 30%, which can push your total rent burden past 40% of income. HUD limits this at initial leasing: most PHAs cap your share at 40% of adjusted monthly income when you first move in [1].
One more wrinkle. The authority calculates a utility allowance for the unit. If utilities are included in rent, this is straightforward. If you pay utilities separately, the allowance is subtracted from your share, which can lower your out-of-pocket cost, sometimes to zero.
What is a payment standard and who sets it?
The payment standard is the dollar ceiling your local housing authority uses when it calculates your voucher subsidy. Each public housing authority (PHA) sets its own schedule based on HUD's published Fair Market Rents (FMRs) for that metro area or county [2].
PHAs have room to move. They can set payment standards anywhere between 90% and 110% of FMR without asking HUD, and they can request permission to go higher in tight markets [2]. That is why two cities in the same state can land in very different places.
HUD publishes updated FMRs every October for the coming fiscal year. The FY2025 FMRs pull from American Community Survey rent data plus more recent market trends [2]. You can look up your area's number on HUD's FMR page.
| Bedroom size | 2025 national median FMR (approx.) | Typical PHA payment standard range |
|---|---|---|
| Studio (0-BR) | ~$1,050 | $945, $1,155 |
| 1-bedroom | ~$1,230 | $1,107, $1,353 |
| 2-bedroom | ~$1,520 | $1,368, $1,672 |
| 3-bedroom | ~$2,000 | $1,800, $2,200 |
| 4-bedroom | ~$2,380 | $2,142, $2,618 |
These are rough national medians. Markets like San Francisco, Boston, or New York run FMRs three to four times higher than rural Midwest counties. Always check HUD's FMR page or ask your PHA for the exact figure where you live [2].
Some large PHAs use Small Area FMRs (SAFMRs), which set a different payment standard zip code by zip code inside a metro. This approach, now mandatory in certain metros, lets voucher holders afford units in higher-opportunity neighborhoods instead of getting priced out [3].
How much of the rent does Section 8 actually pay in dollars?
The honest answer is: it varies a lot. A household with very low income, say $600 a month in adjusted income, owes $180 (30%). In a market with a $1,200 one-bedroom payment standard, the voucher covers $1,020 a month. That is about 85% of rent. A household with $2,000 in monthly adjusted income owes $600, so the voucher covers $600 against a $1,200 standard. That is 50%.
Nobody has a single clean national number, because PHAs report differently and market rents swing so widely. The closest published figure comes from HUD's FY2024 budget justification, which put the average monthly Housing Assistance Payment (HAP) per voucher near $1,020 [4]. Treat that as a rough center of gravity, not a promise.
For extremely low-income families, those under 30% of Area Median Income, the voucher can cover 90 to 100% of rent because their 30% share is so small. Federal rules at 24 CFR 982.508 set a minimum tenant rent of $50 a month for households that would otherwise owe nothing, unless the PHA waives even that for financial hardship [1].
Here is the takeaway. If your income is very low and you rent a unit at or below the payment standard, Section 8 covers most of your rent. As your income rises, or as you choose pricier housing, your share climbs right along with it.
What counts as 'adjusted income' when calculating your share?
Your share of rent is based on adjusted income, not gross income. The difference is real money. HUD allows a fixed $480 deduction for each dependent, a $400 deduction for elderly or disabled households, deductions for childcare that lets an adult work, and deductions for certain disability-related expenses [5].
So a family of four with two children and $24,000 in gross annual income ($2,000 a month) might land closer to $1,200 in adjusted monthly income after dependent deductions, cutting their rent share from $600 to $360.
The PHA recalculates your income at least once a year during your reexamination. Income drops, your share drops. Income rises, your share rises. Interim recalculations happen if your income shifts a lot mid-year, often defined as a change of $200 or more per month [5].
Some households get a zero-HAP determination: their income is high enough that their required share meets or beats the rent. The voucher is not gone. Rules at 24 CFR 982.455 let it stay in place for up to 180 days in case your income falls again [1].
Does Section 8 cover utilities?
This part trips people up constantly. Section 8 does not pay utility companies directly. Instead, the PHA calculates a utility allowance for each unit type based on typical costs for heat, electricity, water, and trash [6]. That allowance gets folded into the subsidy math.
If you pay utilities separately, the allowance is subtracted from your tenant share. Sometimes that creates a utility reimbursement: if your calculated allowance is bigger than what you would owe in rent, the PHA sends you the difference as a check [6]. This shows up most often for very low-income households renting modest units with separate utilities.
If the landlord bundles all utilities into the rent, there is no separate allowance calculation. You pay for utilities through rent, and the standard formula applies.
PHAs update utility allowances on a schedule, but some are badly out of date. If yours does not reflect real costs in your area, you can request a review. HUD rules at 24 CFR 982.517 require PHAs to revise allowances at least once a year [1].
How do payment standards differ by city and state?
The range is enormous. In FY2025, a two-bedroom FMR in rural Mississippi might sit around $750 a month, while the same bedroom size in San Jose, California runs above $3,000 [2]. PHAs in expensive metros often get exception payment standard approval from HUD to go past 110% of FMR, because otherwise a voucher barely works in those markets.
Here is why this matters in practice. If you port your voucher to a new city (move your subsidy into a new PHA's jurisdiction), the receiving PHA applies its own payment standard [7]. Porting from a low-cost area to a high-cost one can leave you with a gap unless you have income to fill it. The housing choice voucher program portability rules at 24 CFR 982.353 let you move almost anywhere in the country, but the dollars adjust to where you land.
Small Area FMRs, now required in roughly 24 metros and optional elsewhere, push this further by varying the payment standard within a metro by zip code [3]. A higher-rent zip gets a higher payment standard. HUD's 2018 SAFMR analysis found the approach improved voucher holders' access to lower-poverty neighborhoods.
Look up your metro's FMR on HUD's FMR page, or ask your caseworker for the current payment standard schedule. PHAs have to give you that schedule in writing.
What can Section 8 not cover?
The voucher covers rent and, through the utility allowance, some utility costs. It does not cover security deposits, application fees, moving costs, furniture, renter's insurance, or repairs the tenant is responsible for.
Section 8 also will not pay rent on a unit that fails HUD's Housing Quality Standards (HQS) inspection. If a place does not meet minimum habitability, the voucher cannot be used there until the landlord fixes what the inspector flagged [8]. This catches people off guard when a unit they love fails.
The voucher cannot cover rent above the payment standard unless the tenant makes up the difference. And if your family is smaller than the approved voucher size, some PHAs restrict which bedroom sizes you can rent, which changes what qualifies.
Section 8 does not cover rent owed before your lease start date, or any month you were out of compliance with program rules. Late rent on your share is still owed to the landlord, and repeated nonpayment can end in eviction even with an active voucher.
For landlords weighing whether to accept vouchers, VoucherReady's landlord kit runs through these limits alongside the payment mechanics, so nothing surprises you at lease signing.
How does Section 8 coverage change as your income changes?
This is the self-correcting part of the design. Income up, your 30% contribution rises and the voucher pays less. Income down, the voucher covers more. The point is to keep your housing cost near 30% of what you earn.
There is a time lag. Annual reexaminations mean your share usually adjusts once a year unless you report a big change. Some PHAs run interim recalculations for income increases but not decreases, or the reverse. Ask your caseworker which direction triggers an interim update at your PHA.
HUD's Moving to Work (MTW) program lets some PHAs use flat-rate rents or tiered scales instead of the strict 30% formula [9]. Around 140 PHAs are in MTW as of 2024, so in those jurisdictions the math can look different.
The rental assistance does eventually end for some households. There is no income line where you automatically lose a voucher, but PHAs stop the subsidy once your required share meets or exceeds the rent, the zero-HAP situation above. After 180 days in zero-HAP status, the voucher can be terminated [1].
How does Section 8 work for landlords: what do they actually receive?
Landlords get the Housing Assistance Payment (HAP) straight from the PHA, usually by direct deposit on the first of the month. They collect the tenant's share separately. Add the two together and you get the contracted rent.
A landlord renting at $1,400 a month to a tenant whose share is $350 collects $350 from the tenant and $1,050 from the PHA. The PHA payment is dependable as long as the tenant stays in compliance and the unit stays HQS-compliant.
If the tenant stops paying their share, the HAP still lands. The landlord's remedy for the unpaid tenant portion is eviction, same as any non-paying tenant, but the government share does not vanish. That is one reason landlords who understand the program like it. Partial payment risk beats full vacancy risk.
Landlords cannot charge a voucher tenant more than they charge comparable unassisted tenants. This rent reasonableness rule gets checked by the PHA at initial lease-up and at any rent increase [8]. Overcharging is a federal contract violation.
The section 8 program also requires landlords to give the tenant 30 days written notice of a proposed rent increase and to get PHA approval before it takes effect.
Are there income limits that determine who qualifies for any coverage at all?
Yes. To get a voucher in the first place, your household income has to be at or below 50% of the Area Median Income (AMI) for your area [10]. By law, PHAs must admit at least 75% of new voucher recipients from households at or below 30% of AMI [10]. So most people who actually receive vouchers sit at the very low end.
AMI shifts by metro. In 2025, 50% of AMI for a four-person household runs roughly $45,000 in a mid-cost city but can top $80,000 in San Francisco or New York. HUD publishes income limits by area every year on its income limits page [10].
Once you hold a voucher, you do not have to keep meeting those limits forever. The program is built to keep households housed as incomes climb. But as your income approaches market rent, the practical subsidy shrinks and eventually hits zero.
If you are on a waiting list and your income climbs above the limit before you reach the top, some PHAs drop you. Check your PHA's policy. Some judge income at the time of admission, not at the time you applied.
How do you find out exactly how much your voucher will cover before signing a lease?
Ask your PHA caseworker for three documents before you start apartment hunting. First, the current payment standard schedule for your voucher bedroom size. Second, the current utility allowance schedule for the unit type you want (apartment vs. house, utilities included vs. not). Third, your family's Total Tenant Payment (TTP), which is your required monthly contribution.
With those three numbers, the math is clean: payment standard minus TTP equals the most HAP the authority will pay. Any rent above the payment standard comes out of your pocket on top of TTP.
PHAs have to give you this information, and many post it online. If yours does not publish it or your caseworker is slow, look up FMRs on HUD's FMR page and estimate backward, knowing the PHA's standard sits somewhere between 90% and 110% (or higher with exception approval) [2].
Once you find a unit, the PHA runs a rent reasonableness check before approving the lease. That takes one to three weeks at most PHAs. Build it into your timeline. VoucherReady's tenant tools include a payment estimator that walks through this exact calculation if you want to model scenarios before you start looking at section 8 houses for rent.
To see what else is out there, you can also check open section 8 waiting lists for other jurisdictions with more favorable payment standards.
Frequently asked questions
How much does Section 8 cover per month on average?
HUD's FY2024 budget justification reported an average monthly Housing Assistance Payment near $1,020 nationally. That number hides huge variation: a rural Midwest voucher might average $700 a month while a coastal metro voucher tops $1,800. Your actual benefit depends on your adjusted income, family size, bedroom size, and your PHA's payment standard.
What percentage of rent does Section 8 pay?
For most active voucher holders, Section 8 covers 60 to 90% of rent. Households at 30% of AMI or below often see coverage above 90%. Households closer to 50% of AMI, or those who pick units above the payment standard, may drop to 50% or less. HUD's formula targets a 30% of adjusted income contribution from the tenant, with the voucher covering the rest up to the payment standard.
Does Section 8 pay the full rent?
Rarely, but it can. If your income is very low and the rent is at or below the payment standard, the voucher may cover 95 to 100% of rent (subject to the $50 minimum tenant payment rule under 24 CFR 982.508). Most households pay some portion. If you pick a unit above the payment standard, you always pay more than your standard 30% share.
What is the maximum rent Section 8 will approve?
There is no single national cap. Each PHA sets its payment standard at 90 to 110% of HUD's Fair Market Rent for the area, and some get exception approval to go higher. In 2025, a two-bedroom payment standard runs from under $800 in rural areas to over $3,000 in high-cost metros. The PHA also runs a rent reasonableness check and won't approve a rent above comparable unassisted units nearby.
Do I have to pay anything if I have a Section 8 voucher?
Yes. HUD requires a minimum tenant payment, set at the greater of 30% of adjusted monthly income, 10% of gross monthly income, or $50, unless your PHA waives the minimum for hardship. You also cover any rent above the payment standard if you choose a pricier unit. Utility costs not covered by an allowance are yours too.
How does Section 8 cover utilities?
The program does not pay utility companies directly. PHAs calculate a utility allowance per unit type. If you pay utilities separately, that allowance cuts your tenant share. If the allowance is bigger than your calculated rent contribution, the PHA issues you a utility reimbursement check. If utilities are bundled into rent, the allowance folds into the overall payment calculation under 24 CFR 982.517.
What does Section 8 not cover?
Section 8 does not cover security deposits, moving costs, application fees, furniture, renter's insurance, or repairs the tenant is responsible for. It does not cover rent on units that fail HUD Housing Quality Standards inspection. It won't cover rent above the payment standard without the tenant paying the difference. Late fees and court costs are always the tenant's responsibility.
How much does Section 8 cover for a 2-bedroom apartment?
The 2025 national median FMR for a two-bedroom is about $1,520, so a typical PHA payment standard falls between $1,368 and $1,672. Your voucher pays that standard minus your 30% income contribution. In high-cost cities like San Jose or New York, two-bedroom payment standards can exceed $3,000. Always confirm the exact figure with your PHA.
Does Section 8 coverage change if my income goes up?
Yes. Your tenant share is recalculated at least once a year. If your income rises, your required 30% contribution rises and the HAP the authority pays drops. If your income rises high enough that your share equals the rent, the voucher enters zero-HAP status and can be terminated after 180 days under 24 CFR 982.455. There is no hard income ceiling that terminates a voucher before that point.
How does Section 8 work in high-cost cities where rents are much higher than the payment standard?
In expensive metros, PHAs can request exception payment standards above 110% of FMR, or they may be required to use Small Area FMRs that vary by zip code. Even so, voucher holders often struggle to find units at or below the payment standard. You can pick a unit above the standard, but you pay the whole difference plus your 30% share, which can push your rent burden well past 40% of income.
Can a landlord charge more than Section 8 will pay?
Yes, and many do. If the rent exceeds the payment standard, the tenant pays the difference on top of the standard 30% share. But a landlord cannot charge a Section 8 tenant more than they charge comparable unassisted tenants for the same unit. This rent reasonableness requirement is enforced by the PHA under 24 CFR 982.507 and checked before any lease is approved.
How do I calculate my Section 8 benefit before I find an apartment?
Get your Total Tenant Payment (TTP) and the payment standard from your PHA. Subtract TTP from the payment standard. That is the most the authority will pay. Example: payment standard $1,400, TTP $350, maximum HAP $1,050. Rent at $1,300 and the HAP is $950, you pay $350. Rent at $1,500 and the HAP stays $1,050, you pay $450.
What income limits apply to get Section 8 coverage?
Initial eligibility requires household income at or below 50% of Area Median Income. By law, 75% of new vouchers go to households at or below 30% of AMI. AMI varies by metro and family size. HUD publishes annual income limits by area. Once you have a voucher, rising income does not automatically disqualify you but does shrink the dollar value of the subsidy.
Does Section 8 cover a room in a shared house or just entire apartments?
In most cases, vouchers cover whole units, not individual rooms. Shared housing is allowed in certain situations, including when a family rents a single room under a lease for the whole property. HUD issued guidance in 2023 expanding some flexibility for shared housing, especially for people experiencing homelessness. Check with your PHA for the rules in your jurisdiction.
