Screening rental applicants is the single biggest control a landlord has over cash flow. A great tenant pays on time, stays for years, and treats the unit like their own; a bad tenant can mean months of lost rent, property damage, and a costly eviction. This tenant screening calculator turns the four numbers landlords actually rely on — rent, income, credit score, and rental history — into a plain Approve, Review, or Deny recommendation so you can compare applicants consistently instead of going by gut feel.
Enter the asking rent and the applicant's gross monthly income first. The calculator checks whether income meets the common 3x rent rule, measures how heavy the rent load actually is, then layers in the credit score threshold, any eviction filing, and any broken-lease or late-payment history. Every box updates as you type.
How to Use
- Enter the Monthly Rent you are asking for the unit — for example, $1,800. This is the benchmark all income math is built around.
- Type the applicant's Gross Monthly Income — the total before taxes, not their take-home pay. On a $1,800 rent, the default $5,400 represents the classic 3x threshold.
- Adjust the Required Income Multiple if your market or owner has a different standard. 3x is the default, but many coastal cities and luxury buildings ask for 40x the monthly rent in annual income (the same as roughly 3.3x monthly), and some Section 8 or corporate-guarantee programs use different rules.
- Enter the applicant's Credit Score from the screening report, then set your Minimum Credit Threshold. 620 is a common cutoff; FHA-friendly landlords often accept 580, while premium buildings may require 700 or more.
- Set Eviction History to "yes" if any eviction filing or judgment appears on the report, and set Broken Lease / Severe Rental Issues to "yes" if there is an unpaid prior balance, a broken lease, or a documented pattern of late payments.
- Read the result card. It shows the required income, the applicant's income-to-rent multiple, rent as a percent of income, an individual pass/fail for each of the four checks, how many checks passed, and a final recommendation.
The recommendation rule is simple: an eviction on record is treated as an automatic Deny no matter how strong the income or credit. If there is no eviction, passing all four checks means Approve; passing exactly three means Review (ask for a larger deposit, a co-signer, or additional documentation); passing two or fewer means Deny.
The 3x Rent Rule and the 30% Guideline
Landlords usually require gross monthly income of at least 3 times the rent. On $1,800 that means required income of $5,400. This is the screening-side cousin of the budgeter's 30% rule, under which housing should consume no more than 30% of gross income. Notice that 3x rent is mathematically the same as rent being one third (about 33%) of income — slightly tighter than the 30% housing guideline, because landlords want a cushion for taxes, utilities, and debt.
If an applicant earns $5,400 on $1,800 rent, the income-to-rent multiple is 3.0x and rent is 33.3% of their gross income — right at the line. If they earn $6,000, the multiple rises to 3.33x and rent falls to 30%, which is a comfortable margin. If income is $4,500, the multiple is only 2.5x and rent eats 40% of gross income, leaving little room for a car payment or an emergency, which is exactly why such applicants default more often.
A credit score threshold works the same way: it is a fast filter, not a verdict. A score of 620 is the most common minimum because it roughly separates "prime" from "subprime" borrowing. Below it, missed payments and high balances are statistically more common. Pair the credit filter with the income filter — a high score with weak income and a low score with strong income both deserve a Review rather than an automatic answer.
What Each Screening Check Means
- Income check — gross monthly income at least rent times the multiple. This protects against tenants who would be rent-burdened and likely to fall behind the first month a car repair or medical bill hits.
- Credit check — the applicant's score meets your threshold. It proxies for how reliably they pay existing obligations, including other people's money.
- Eviction history — any prior eviction filing or judgment is the single strongest predictor of future eviction and is treated as a hard fail.
- Rental history — broken leases, unpaid balances, and repeated late payments show whether the applicant has honored prior lease terms, which is often more predictive than a credit score alone.
Used together, these four checks catch most of the predictable risk before you sign a lease.
Examples
Example 1 — The standard applicant. Rent is $1,800, gross income $5,400, credit score 620, no eviction, no broken lease. Required income is $5,400, the income-to-rent multiple is 3.0x, and rent is 33.3% of income. All four checks pass, so the recommendation is Approve — right at the qualifying line.
Example 2 — Thin credit, solid income. Rent $1,800, income $5,400, but credit score only 580, below the 620 threshold, with a clean rental history. Income passes and both history checks pass, but credit fails: three of four checks pass, so the recommendation is Review. Ask for a larger security deposit, a qualified co-signer, or several additional months of bank statements to offset the low score.
Example 3 — High income, eviction on file. Rent $1,800, strong income of $6,000 (3.33x, 30% of income), credit 700 — but an eviction filing appears on the report. Even though income and credit are excellent, the eviction is a hard fail, so the recommendation is Deny. This is the most common trap for new landlords: an impressive bank statement cannot erase a prior non-payment or holdover.
Example 4 — A luxury stress test. On a $18,000/month unit with an applicant earning $1,200,000 a month, the income-to-rent multiple is a very high 66.7x and rent is only 1.5% of income. The calculator must handle incomes this large cleanly; in practice, high-net-worth applicants clear the income and credit checks easily, and the screening question narrows to source-of-funds and verification rather than affordability.
FAQ
What is the 3x rent rule?
It means a landlord wants the applicant's gross monthly income to be at least three times the monthly rent. On a $1,800 apartment, required income is $1,800 × 3 = $5,400. Multiply the asking rent by three to get the minimum monthly income you should accept.
What credit score do you need to rent an apartment?
There is no legal minimum, but 620 is the most widely used cutoff. Scores of 620 or above are commonly approved, 580–619 usually require a co-signer or larger deposit, and scores below 580 are often denied unless the applicant has substantial savings or a guarantor.
Does an eviction automatically disqualify an applicant?
Most landlords treat a prior eviction as an automatic Deny because it is the strongest available predictor of future eviction. Some will consider an applicant after the eviction is several years old and paid in full, with a larger deposit and a co-signer — but this calculator flags it as a hard fail to keep screening consistent.
Should I use gross or net income for tenant screening?
Always use gross monthly income — the amount before taxes and deductions. Using take-home pay overstates the applicant's ability to cover rent, because taxes, retirement contributions, and insurance already come out of that figure. The 3x rule is built on gross income, the same way the 30% budget guideline is.
What is a good rent-to-income percentage?
Under 30% of gross income is comfortable, 30%–35% is acceptable with a cushion, and anything above 40% signals rent burden. On $5,400 gross income, $1,800 rent is 33.3% — borderline acceptable. Many landlords prefer to see rent stay at or below 30% to reduce default risk.
What is the difference between Review and Deny?
A Review means the applicant passes three of four checks and is worth a second look with a larger deposit, a co-signer, or extra documentation. A Deny means two or fewer checks passed, or an eviction is on record — the risk is too high to approve under your stated criteria.
