Section 8 Rent Calculator: Estimate Your Payment

The process of determining housing assistance payment amounts for the Housing Choice Voucher Program (HCV) involves several factors. Generally, a voucher recipient pays 30% of their adjusted monthly income towards rent. The housing agency then subsidizes the difference between that amount and the payment standard for the area, up to the approved rent for a particular unit. For example, if the payment standard for a two-bedroom apartment is $1,200 and the family’s share is $400, the housing agency would pay the landlord $800. However, if the actual rent charged is $1,100, the agency would only pay $700, and the familys contribution would remain at $400. Various regulations and policies govern eligibility, payment standards, and rent reasonableness.

Accurately determining subsidized housing payments is essential for both landlords and tenants. It ensures fair and predictable housing costs for low-income families, while also providing landlords with reliable rental income. This system, established under the Housing and Community Development Act of 1974, plays a significant role in addressing affordable housing challenges nationwide.
