Calculator

Estimate your share of the rent

Uses HUD's formula. Nothing you type here is saved or sent anywhere.

Enter your yearly income to see an estimate.

An estimate only. Your housing agency works out the real amount from verified income and may use a lower minimum rent, different utility allowances, or older deduction amounts.

How it works

How the numbers are worked out

Your share is called the total tenant payment. It is the highest of 30% of your monthly adjusted income, 10% of your monthly gross income, any welfare rent for housing in some states, and your housing agency's minimum rent (up to $50 for vouchers).

Adjusted income is your income after deductions. For 2026 the calculator uses $500 for each dependent and $550 for an elderly or disabled family, plus child care that lets someone work or study and, for elderly or disabled families, medical costs above 10% of income.

If you add a rent and a payment standard, it also shows the agency's payment: the lower of the payment standard or the rent, minus your share. When you first move in, your share can't be more than 40% of your adjusted income.

This is an estimate, not a decision. KPCB Edge is an independent publisher, not a government agency, and only the agency that runs the program can decide whether you qualify.

Good to know

Questions about this tool

Is this the amount I will really pay?

No. It is an estimate. Your housing agency works out the real figure when it verifies your income, and its minimum rent, deductions and payment standard may differ from the ones used here.

What is a payment standard?

It is the most your housing agency will pay toward rent and utilities for a voucher of your size. Each agency sets its own, usually between 90% and 110% of HUD's Fair Market Rent for the area.

Can I rent a home that costs more than the payment standard?

Yes, but you pay the difference. When you first move into a unit above the payment standard, your share can't be more than 40% of your adjusted monthly income, and the agency will not approve a unit that would push you over it.

What if I have no income?

Your share may be your agency's minimum rent, which can be up to $50 a month. If you can't pay it because of a hardship, such as losing a job, ask the agency for a hardship exemption.

Does the voucher pay my security deposit?

No. The landlord may collect a deposit, and the voucher does not pay it. Ask your housing agency whether it knows of local help.
