A rent-to-income ratio compares a renter’s individual or household monthly income to the amount they pay monthly for rent. It is a common financial benchmark landlords use to understand how much financial stress a rental contract will put on a tenant. Before signing a contract, you should calculate this ratio to understand what you can reasonably afford.

The concept of the rent-to-income ratio became popular in 1969 with a starting benchmark of 25%. It was later increased to 30% by Congress in 1981 to reduce the Federal government’s housing subsidy.

Why Knowing Your Rent-to-Income Ratio Is Important

Renters vs. Landlords

For renters, the rent-to-income ratio is a benchmark for making informed financial decisions. It provides a clear picture of affordability, helping a renter gauge what proportion of their income will go towards rent.

Understanding this ratio can aid in establishing a healthier, more balanced budget. It can help ensure that renters don’t overcommit, which can lead to missed payments, debt, ruined credit or having to sacrifice other essential expenses, like food and clothing.

For landlords, the rent-to-income ratio is a risk assessment tool. A potential tenant with a high income and a low ratio is more likely to make their rent payments on time and in full.

A landlord will be less likely to offer a contract to an applicant with a ratio significantly above 30%. In some cases, like with affordable housing, landlords may not even accept applications from people whose rent-to-income ratio doesn’t meet a state-mandated threshold.

Calculating Your Rent-to-Income Ratio

Calculating your rent-to-income ratio can help you understand what’s affordable. Take your monthly rent and divide it by your gross monthly income. This calculation gives you the portion of your income spent on rent. To express this as a percentage, multiply the ratio by 100.

High Ratio Example

Let's consider Jane, a renter in a bustling city. Her monthly rent is $1,500, and she makes $3,000 per month before taxes and deductions. To find her rent-to-income ratio, she divides her monthly rent by her monthly income and multiplies the result by 100.

Jane’s ratio turns out to be 50% — half of her income is spent on rent. Jane has $1,500 left over to use for expenses like commuting, clothing, groceries, saving and emergencies.

high ratio

For Jane, a high rent-to-income ratio of 50% signals potential financial concerns.

Jane's capacity to save or invest could be severely limited. With half of her income allocated to rent, she may struggle to put aside funds for future financial goals or invest to grow her wealth. Jane may also not have sufficient financial flexibility to cope with unexpected expenses. A costly car repair or a medical emergency could push her into debt and cause her to miss rental payments.

Jane has a few options to reduce her rent-to-income ratio. She could seek a higher-paying job, negotiate lower rent or consider more affordable housing options, such as getting a roommate or moving to a less expensive area.

Low Ratio Example

Kevin is a seasoned professional residing in a suburb. His monthly rent is $1,800, but his gross monthly income is $7,500. Kevin divides his rent by his income and multiplies the result by 100. He discovers his ratio is 24% — less than a quarter of his income is dedicated to rent, giving him financial flexibility. This low ratio exemplifies a manageable and healthy financial scenario for a renter.

A low ratio like Kevin's often translates to higher saving and investing capacity. With less income tied up in rent, Kevin can build a robust emergency fund, contribute to retirement savings and invest in opportunities to grow his wealth over time.

Kevin also has the flexibility to consider larger financial goals, such as purchasing property or investing in higher education. His low ratio allows him to plan and save for these substantial investments.

Understanding Rent Affordability and Rent-to-Income Ratio

Housing affordability has long been challenging in the U.S., particularly because of high rental costs. The U.S. government has made several efforts to tackle this issue, with the rent-to-income ratio emerging as a crucial concept in evaluating affordability.

This ratio was officially introduced in the 1969 Brooke Amendment to the 1968 Housing and Urban Development Act. This amendment stipulated that residents in public housing should spend no more than 25% of their income on rent, aiming to make housing more affordable for low-income Americans. Over time, and with further amendments, this benchmark was raised to the 30% guideline used today.

Limitations and Criticisms of the Rent-to-Income Ratio


Arbitrary 30% Limit

This universal standard may not consider the unique financial circumstances of different renters. For instance, large families might struggle with this percentage more than single professionals, who may find allocating half of their income to rent acceptable without substantial compromises.

Cost of Living Differences

The ratio doesn't take into account cost-of-living variations across different regions. While housing might be cheaper in certain areas, other living costs could be higher and vice versa.

Tradeoffs to Meet the 30% Benchmark

This critique focuses on the sacrifices renters, particularly families, tend to make to keep their housing costs within the recommended ratio. They might accept poor-quality housing, reside in areas with high crime rates or choose locations far from their workplaces, significantly impacting their quality of life.
