Section 8 rent calculator

Estimate the tenant's share and the housing-assistance payment (HAP) under the US Section 8 Housing Choice Voucher program. It applies HUD's rules — $480 per dependent and a $400 elderly/disabled deduction — to reach adjusted income, takes 30% of the monthly adjusted income as the Total Tenant Payment, and compares your unit's gross rent against the payment standard to size the subsidy.

Frequently asked questions

What does the Section 8 rent calculator actually compute?

It takes Annual household income, Number of dependents, Household type, Other deductions (childcare, medical…), Fair Market Rent (monthly), Payment standard (% of FMR), Unit rent (contract rent, monthly) and Utility allowance (monthly) and derives Adjusted annual income, Monthly adjusted income, Total Tenant Payment (30%), Payment standard, HAP subsidy (to landlord) and Tenant portion (rent + utilities) from them. The calculation is live as you type, so the result updates on every change.

What information do I need to provide?

8 values: Annual household income ($), Number of dependents, Household type, Other deductions (childcare, medical…) ($), Fair Market Rent (monthly) ($), Payment standard (% of FMR) (%), Unit rent (contract rent, monthly) ($) and Utility allowance (monthly) ($). Nothing else is required — no account, no file upload.

Can you show a worked example?

With Annual household income = $24,000.00, Number of dependents = 2, Household type = Standard, Other deductions (childcare, medical…) = $0.00, Fair Market Rent (monthly) = $1,500.00, Payment standard (% of FMR) = 100%, Unit rent (contract rent, monthly) = $1,450.00 and Utility allowance (monthly) = $100.00, the calculator returns Adjusted annual income = $23,040.00, Monthly adjusted income = $1,920.00 and Total Tenant Payment (30%) = $576.00. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

What happens if I enter larger values?

It moves a lot. Using Annual household income = $48,000.00, Number of dependents = 4, Household type = Elderly / disabled (+$400 deduction), Other deductions (childcare, medical…) = $5.00, Fair Market Rent (monthly) = $3,000.00, Payment standard (% of FMR) = 110%, Unit rent (contract rent, monthly) = $2,900.00 and Utility allowance (monthly) = $200.00 instead, Adjusted annual income goes from $23,040.00 to $45,675.00 — which is why it is worth testing a few scenarios rather than trusting a single figure.

Which “Household type” option should I choose?

You can pick between « Standard » and « Elderly / disabled (+$400 deduction) ». Each one changes what the calculator works out, so switch and compare — the default is « Standard ».

Which units should I enter the values in?

Enter Payment standard (% of FMR) %.

What does it give for smaller values?

Scaled down to Annual household income = $12,000.00, Number of dependents = 1, Household type = Standard, Other deductions (childcare, medical…) = $1.00, Fair Market Rent (monthly) = $750.00, Payment standard (% of FMR) = 90%, Unit rent (contract rent, monthly) = $725.00 and Utility allowance (monthly) = $50.00, Adjusted annual income comes out at $11,519.00. The relationship is worth checking at both ends before you rely on a single result.

When would I actually use this?

Setting or checking a rent, working out the yield a property really returns, and splitting a part-month at the start or end of a tenancy.

What is the most common mistake?

Quoting a gross yield. Once charges, tax, insurance, management and vacancy are taken out, the net figure is routinely a third to a half lower.

How accurate is it, and what are the limits?

Estimate only. Public Housing Agencies set local payment standards, utility allowances and minimum rents that vary — confirm with your PHA.

ExplainerWhat a Housing Voucher Actually PaysThe tenant's share is a percentage of adjusted income; the subsidy is the gap up to a payment standard.

Agree on one before you sign, not after.ExplainerThe Most Rent You Should Agree ToThree different numbers decide a letting: the rent the agent screens, the total occupancy cost your budget has to survive, and the cash due at signing. On a $1,800 listing they are $1,800, $2,095 and $3,600.ExplainerWhat a Rent Increase Is Allowed to BeFive of six markets index the permitted increase to a published statistic, and each names a different one. The arithmetic is universal: on a $1,500 rent, ten years at a 1 percent index leaves you 25.38 percent below a market that grew 4 percent.GuideSplitting Rent Between Rooms That Are Not the SameEqual thirds of $2,400 charge the same for 180 square feet and for 100. Floor area is better and still leaves someone envious.

The rule is a fixed percentage applied to a budget whose other needs are not proportional to income — which is exactly why housing policy uses residual income instead.
