The Novogradac Rent & Income Limit Calculator is a specialized tool designed for housing professionals. Its purpose is to simplify the complex calculations needed to determine income and rent limits for affordable housing programs, including the Section 42 Low Income Housing Tax Credits (LIHTC) and Section 142 Tax-Exempt Bonds.

Purpose and Functionality

This calculator is crucial in the affordable housing sector, helping to ensure that housing remains accessible to those who need it most. It uses various inputs like Area Median Income (AMI), family size, and specific program requirements to calculate the maximum income a household can earn to qualify for affordable housing, as well as the maximum rent that can be charged for a unit under these programs.


To put the formula used by the Novogradac Rent & Income Limit Calculator into simple words, let's break it down into a step-by-step process:

  1. Figure out the middle income for where you live (AMI): This is like finding the middle ground of what everyone in your area earns in a year. The government updates this number every year.
  2. Set limits on how much money you can make to get affordable housing (Income Limits): This part uses the middle income we just found and adjusts it based on how many people are in your family. There are specific cutoffs, like if your family makes less than 30%, 50%, or 80% of that middle income, you might qualify for cheaper housing.
  3. Calculate the most you can be charged for rent (Rent Limits): Based on how much money your family can make and still qualify, this step figures out the highest rent you can be charged for a place to live. It makes sure that rent doesn't take up more than a fair part of your monthly income, and it even takes off some money for your utility bills.
  4. Adjust for how big your family is and how many bedrooms you need (Adjustments for Household Size): If you have a bigger family or need more bedrooms, the calculator tweaks the numbers to make sure everything still works out fairly.
  5. Consider any special rules (Program-Specific Requirements): Sometimes, there are extra rules to think about, like if you live in a place where living costs are really high, or if there are specific ways you need to include your bills in your rent calculation.

An example to make it clearer: If you're looking at a 2-bedroom home and your area's middle income (AMI) is $36,000, and your family's income is 60% of that (which is $21,600 a year), the calculator helps figure out how much rent you can afford without spending too much of your income, taking into account your family size and any money you need to set aside for utilities.

Step-by-Step Example

Let's break down how the calculator might work for a 2-bedroom unit in an area where the AMI is $36,000:

  1. Input the AMI: $36,000 for the area.
  2. Determine Income Limits: Apply percentages (30%, 50%, 80%) to the AMI based on program requirements, adjusting for family size.
  3. Calculate Rent Limits: Use the income limit for a household at 60% of the AMI and subtract any utility allowances to find the maximum rent.

For a household size relevant to a 2-bedroom unit, the income limit could be 60% of the AMI, and the rent limit could be 30% of this adjusted monthly income minus utility allowances.
