When assessing whether a potential tenant is a good fit, you look at many factors. One of the most vital is their financial stability. A way to gauge this is to calculate their rent-to-income ratio. In this article, you’ll learn how to determine the metric, what a strong ratio is, and how to use our rent-to-income ratio calculator.

What is rent-to-income ratio?

The rent-to-income ratio calculates how much income the tenant earns in relation to the rent. It’s a percentage metric that allows you to know how affordable the rent is for that tenant. The higher the ratio, the more income the person would need to allocate for rent.

Let’s review the calculations.

How to calculate rent-to-income ratio

There are three ways to calculate the ratio:

  • Predetermined rent-to-income ratio
  • Rent-to-income ratio multiplier
  • Property-based calculations

The basic formula for the ratio is the income divided by the rent amount, multiplied by 100.

Predetermined rent-to-income ratio

The predetermined method uses a fixed percentage to assess a tenant’s ability to afford the rent. The fixed number comes from industry standards or landlord preferences.

How it works

  1. Set the percentage: Determine the percentage of income you expect tenants to allocate toward rent. A common standard is 30%.
  2. Calculate maximum rent: Multiply the tenant's gross monthly income by this percentage to find the maximum rent they can afford.

Example

  • Tenant's gross monthly income: $5,000
  • Predetermined percentage: 30%
  • Maximum rent = Gross monthly income × predetermined percentage
  • Maximum rent = 5,000 × 0.30 = 1,500

In this example, the tenant should ideally pay no more than $1,500 in rent.

Rent-to-income ratio multiplier

The rent-to-income ratio multiplier method involves setting a multiplier to calculate the minimum income required to afford the rent. This approach is often ideal for assessing a tenant’s financial suitability quickly.

How it works

  1. Determine the multiplier: Choose a multiplier based on your desired rent-to-income ratios. A common multiplier is 3, meaning the tenant’s income should be at least three times the monthly rent.
  2. Calculate required income: Multiply the monthly rent by the chosen multiplier to determine the minimum income needed.

Example

  • Monthly rent: $1,200
  • Multiplier: 3
  • Required income= Monthly rent × multiplier
  • Required income=1,200 × 3 = 3,600

In this example, the tenant needs a gross monthly income of at least $3,600 to afford the $1,200 rent.

Property-based calculations

The property-based calculation accounts for specific characteristics and costs associated with a particular property. It considers the unique aspects of each rental.

How it works

  1. Analyze property costs: Assess all costs associated with the property, including maintenance, utilities, taxes, and insurance.
  2. Determine necessary income: Calculate the total monthly costs and apply a desired profit margin. Use this total to determine a tenant's minimum income to afford the rent comfortably.

Example:

  • Monthly property costs: $700 (including maintenance, utilities, taxes, and insurance)
  • Desired profit margin: 50%
  • Monthly rent: Property costs + profit margin
  • Monthly rent = 700+ (700×0.50) = 700 + 350 = 1,050

Next, determine the tenant’s required income using the predetermined rent-to-income ratio:

  • Predetermined percentage: 30%
  • Required income = Monthly rent ÷ predetermined percentage
  • Required income = 1,050 ÷ 0.30 = 3,500

In this example, a tenant needs a gross monthly income of at least $3,500 to afford the $1,050 rent, considering the specific costs and profit margin associated with the property.

If math is not your strong suit or you want to simplify the process, the RentSpree calculator is here to help. Use it to crunch the numbers and find the desired ratio for your rental property or applicant.

Why rent-to-income ratio matters

The income-to-rent ratio helps you make more informed decisions about an applicant’s ability to pay rent on time every month. It’s a key piece of information that builds the financial story of a potential tenant. You can consider a way to evaluate the risk associated with non-payment or late payments.

For example, if a tenant's rent-to-income ratio is high, it may indicate that they are financially stretched. As a result, they may be at more risk for late or missing payments.

On the other hand, if the ratio is within a reasonable range, for example, between 25-30%, it suggests that the tenant's income is sufficient. They would be less likely to have financial issues during the tenancy.

Calculating an applicant’s rent-to-income ratio and considering other factors will give you a clear picture of their financial state. You can identify qualified candidates who will most likely pay their rent on time and in full monthly.

The ideal rent-to-income ratio

According to industry standards, the suggested ratio is around 30% or less. This means tenants should ideally spend no more than 30% of their gross monthly income on rent. A 30% ratio usually means the rent is affordable. The person would still have 70% of their income for utilities, groceries, transportation, and savings.

Plus, keeping the ratio within this limit helps tenants maintain a healthy balance between housing costs and other financial obligations. For example, if a tenant has a gross monthly income of $5,000, they should budget for a rent of up to $1,500.

How to use rent-to-income ratio in tenant screening

The ratio is one metric for gauging if a tenant will be able to pay rent on time every time. A higher ratio shouldn’t automatically disqualify someone, but it does offer insight into cash flow.

Ratios above 30% could mean the applicant is too risky. If you’ve been using this in tenant screening, reflect on whether it was a good indicator of their ability to pay. Those who must use more of their income to meet rent obligations could mean that one financial emergency could affect payments.

Use these ratios as one pillar when evaluating a tenant’s complete financial picture. There are more ways to assess this beyond the ratio

Alternatives and supplemental metrics

Income-to-rent ratio is a crucial component of the tenant screening process, but it’s not the only metric to evaluate. For a comprehensive financial overview, you should also use these alternatives and supplemental metrics.

Credit score and history: An applicant’s credit score and history can provide detailed insight into their financial habits and reliability. If they have a good credit score and a positive payment history, it implies responsible financial behavior. A poor credit score suggests a history of mismanagement or difficulty meeting obligations.

Employment verification: You’ll also want to confirm the applicant’s employment status and verify steady income. Someone who has a history of long-term jobs will be more reliable than someone who’s had frequent job changes or is currently unemployed. Keep in mind, however, that job status alone is not necessarily a reason to disqualify a candidate. An unemployed applicant may still be able to afford rent if they have other substantial financial resources or savings.

Rental history: Checking references from previous landlords allows you to verify rental history details. You can confirm information, such as dates of tenancy, rent amount, and payment consistency. It’s an opportunity to ask about an applicant’s behavior, including whether or not they respected the property, followed lease rules, and treated their neighbors well. When you contact references, you can also learn if the applicant made on-time payments and inquire if there were any potential red flags you should know about.

Debt-to-income ratio: This ratio compares the tenant's total monthly debt payments to their gross monthly income. This metric allows you to assess if the tenant can afford the rent in addition to their other debts. A low debt-to-income ratio signifies that the tenant's debt is at a manageable level, making it more probable that they will pay rent punctually. Conversely, a high debt-to-income ratio implies that the tenant might have limited financial stability.

What if the rent-to-income ratio is too high?

In the event a renter’s ratio is higher than 30%, you can implement additional safeguards to mitigate potential risks. You can:

  • Ask for an increased security deposit to help your renter keep additional funds in escrow in the event of non-payment.
  • Charge a monthly pet rent as an up-front pet deposit, reducing the rent due month to month.
  • Request a co-signer on the lease and use their income as additional consideration for the renter’s ratio.

Rent-to-income ratio FAQs

What types of income should count?

To get an accurate picture of an applicant’s financial situation, you should evaluate sources of income. When you verify the income of your rental applicant, take these factors into account:

  • Social Security benefits: Verify this with an award letter from the Social Security Administration or by checking bank statements.
  • Alimony and child support payments: Confirm these funds through a court-ordered award letter.
  • Annuity or investment income: Review dividends and payments from investment accounts through a statement from an applicant’s brokerage. Pay particular attention to and verify the expiration of payments to see if they will continue for the foreseeable future.
  • Pension or other retirement income: Validate pension or retirement income through a pension or bank statement.
  • Bonus, commission, and incentive payments: Request proof of income from these sources for at least 2 or 3 months of overall income to determine how steady their cash flow is over time.
  • Self-employment income: Discuss how freelancers and contractors receive payments. To verify they have consistent income, ask for several months’ worth of bank statements to ensure they have the necessary funds to cover rent for an entire month.

Income from worker’s compensation, insurance compensation, severance pay, or court-awarded compensation: Get documentation from the court or company making the payment to ensure the information is accurate.

While you can use any or a combination of these types of income to count toward your applicant’s income, consider how reliable this cash flow is regarding long-term compensation.

For example, while Social Security or pension benefits tend to stay the same month after month, severance or a bonus may constitute a one-time payment. You’ll need to look for ongoing income rather than limiting yourself to an income assessment based on a single, non-repeatable event.

How can you encourage on-time rent payments?

Ensuring tenants pay rent on time directly affects cash flow and the financial health of your rental property. Here are some strategies to encourage timely payments:

  • Clear lease terms: Outline rent payment terms in the lease agreement, including due dates, acceptable payment methods, and late fees.
  • Open lines of communication: Communicate clearly to foster trust, transparency, and accountability in the landlord-tenant relationship. Remind tenants of upcoming rent due dates and be open to discussing assistance or accommodations if a tenant experiences financial difficulties.
  • Automated payments: Streamline the rent payment process with an automatic payment option and monthly reminders sent to your renter’s email or phone. With online, automatic rent payments, you're much more likely to receive payments on time.
  • Consistent reminders: Send out additional reminders as needed, especially if the first of the month falls on a weekend or holiday. Let tenants know where and how they can pay their rent to ensure that it is recorded as an on-time payment.
  • Incentives for on-time payments: Consider offering small incentives for consistent on-time payments, such as a discount on the next month’s rent, a gift card, or credit bureau reporting.
  • Late fees: Implement and enforce a late fee policy. While this is more of a deterrent than an encouragement, it can motivate tenants to pay on time to avoid additional charges.

When should you lower or raise the ideal ratio of 30%?

Much of the “ideal” ratio is dependent on where you live. Major metropolitan areas may see much higher ratios, sometimes up to 50%. You may also choose to lower if the property is a luxury rental.
