U.S. rental property loans
DSCR calculator for rental property loans
The debt service coverage ratio (DSCR) compares a rental property’s income with its loan payments. At 1.00 the income exactly covers the payment; above 1.00 there is a cushion, and below 1.00 the property does not cover its debt. This calculator shows DSCR two common ways, net operating income ÷ debt service and gross rent ÷ PITIA, plus the rent each method needs for a target ratio and the largest loan the income could support. It is an educational estimate, not lending advice.

Formulas
How DSCR is calculated
Lenders and loan programs define DSCR in different ways. The two most common are below; ask any lender which formula, income and costs it uses.
- Principal and interest (P&I)
P&I = L × r × (1 + r)ⁿ ÷ ((1 + r)ⁿ − 1)L is the loan amount, r is the annual rate ÷ 12 and n is the number of monthly payments, for a fixed-rate, fully amortizing loan.
- PITIA
PITIA = P&I + property tax ÷ 12 + insurance ÷ 12 + HOA duesPrincipal, interest, taxes, insurance and association dues: the full monthly payment on a mortgaged property.
- Net operating income (NOI)
NOI = rent × (1 − vacancy %) − tax − insurance − HOA − other operating expensesMonthly income after vacancy and every running cost, before the loan.
- DSCR, NOI method
DSCR = annual NOI ÷ annual debt service (P&I × 12)The usual definition for commercial and multifamily loans, and the one the MyInversorAI app reports. Taxes and insurance count as operating expenses here, not as debt.
- DSCR, rent ÷ PITIA
Ratio = gross monthly rent ÷ PITIAA simpler ratio that many lenders’ rental-income (DSCR) loan programs for one- to four-unit properties look at. It ignores vacancy, repairs and management, so it usually comes out higher than the NOI method.
- Largest loan at a target DSCR
Max P&I = NOI ÷ target; max loan = max P&I × (1 − (1 + r)⁻ⁿ) ÷ rThe payment the NOI covers at the target, turned into a loan amount at your rate and term. It is a coverage limit only; lenders also apply loan-to-value, credit and reserve rules.
- Rent needed for a target
Rent ÷ PITIA: rent = target × PITIA. NOI method: rent = (target × P&I + operating expenses) ÷ (1 − vacancy %)The monthly rent at which each ratio equals the target, with your other inputs unchanged.
Worked example
Worked example: a $2,500-a-month rental with a $240,000 loan
These are the calculator’s starting values. The interest rate is chosen for illustration and is not a rate quote, and the 1.25 target is a common example, not any lender’s requirement.
Assumptions
- Monthly rent
- $2,500 per month
- Vacancy
- 5% of rent
- Property tax
- $3,600 per year
- Insurance
- $1,800 per year
- HOA dues
- $0 per month
- Other operating expenses
- $280 per month (repairs, reserves and management)
- Loan
- $240,000 at 7% fixed for 30 years
- DSCR to test
- 1.25
Step by step
| Step | Calculation | Result |
|---|---|---|
| Loan payment (P&I) | $240,000 at 7% for 360 months | $1,596.73 per month ($19,160.71 per year) |
| PITIA | $1,596.73 + $300 tax + $150 insurance | $2,046.73 per month |
| Net operating income (NOI) | $2,500 − $125 vacancy − $730 operating expenses | $1,645 per month ($19,740 per year) |
| DSCR, NOI method | $19,740 ÷ $19,160.71 | 1.03 |
| DSCR, rent ÷ PITIA | $2,500 ÷ $2,046.73 | 1.22 |
| Cash flow after the loan | $1,645 − $1,596.73 | $48.27 per month |
| Largest P&I at 1.25 | $1,645 ÷ 1.25 | $1,316 per month |
| Largest loan at 1.25 | $1,316 per month at 7% for 360 months | $197,804.76 |
| Rent for 1.25, rent ÷ PITIA | 1.25 × $2,046.73 | $2,558.41 per month |
| Rent for 1.25, NOI method | (1.25 × $1,596.73 + $730) ÷ (1 − 5%) | $2,869.38 per month |
The same property gives two different answers. Rent ÷ PITIA is 1.22, which falls short of the 1.25 test. The NOI method, which also counts vacancy, repairs and management, gives 1.03, which falls short of the 1.25 test, and leaves about $48.27 a month after the loan payment. To reach 1.25, the rent would need to be about $2,558.41 by the first method or $2,869.38 by the second; alternatively, the NOI would cover a loan of about $197,804.76 at the same rate and term. A ratio this close to the line is a reason to recheck the rent, the costs and the loan size before relying on any financing.
Interpretation
What DSCR tells a lender, and what it does not
DSCR is a coverage test: it asks whether the property’s income can carry the debt. It says little about whether the property is a good investment.
What it tells you
- Whether the rent covers the loan payment, and with how much cushion.
- How far income could fall before the payment is no longer covered: at 1.25, NOI could drop by about 20% before it only equals the payment.
- Roughly how large a loan the property’s income can support at a given rate and term.
- How sensitive the deal is to the interest rate: a higher rate raises the payment and lowers DSCR.
What it does not tell you
- Whether a lender will approve a loan. Credit, the down payment, reserves, the appraisal and each program’s rules all matter.
- Your return. A property can have a comfortable DSCR and a low cash-on-cash return, or the reverse.
- Whether you could cover a shortfall from other income or savings.
- Vacancy, repairs and management, when the rent ÷ PITIA method is used.
- Future changes in rent, property taxes, insurance or an adjustable rate.
DSCR loans · General education
DSCR loans, explained in general terms
A DSCR loan is a type of investment property mortgage in which the lender qualifies the loan mainly on the property’s rental income instead of the borrower’s personal income. Programs vary widely; this is general background, not lending advice.
- What they are
- DSCR loans are usually business-purpose, non-QM (non-qualified mortgage) loans for one- to four-unit rental properties, and in some programs larger buildings. Many programs do not ask for tax returns to verify personal income; the property’s rent carries more of the weight.
- How lenders commonly measure coverage
- Lenders often compare the gross monthly rent, from a lease or an appraiser’s estimate of market rent, with the monthly PITIA payment. Minimum ratios are commonly about 1.0 to 1.25, and some programs accept lower ratios on stricter terms. Each lender sets its own rules.
- What else usually matters
- Credit history, the down payment or loan-to-value ratio, cash reserves after closing, the property type and condition, and the appraisal. A strong DSCR does not replace these requirements.
- Trade-offs to ask about
- Compared with conventional investment property loans, DSCR loans often carry higher interest rates and fees, and some include prepayment penalties. Ask each lender for the full terms in writing and compare the total cost.
- Who tends to consider them
- Investors whose personal income is hard to document, such as self-employed borrowers, or who already own several rentals. They are meant for investment properties, not for a home you live in.
- Questions to ask a lender
- Which DSCR formula and rent figure it uses, its minimum ratio, how vacancy and HOA dues are treated, whether an interest-only payment is used in the ratio, and how many months of reserves it requires.
For loan terms and eligibility, talk to a licensed mortgage loan originator; you can look up a license on the NMLS Consumer Access website. This page does not recommend any loan, lender or program.
Thresholds · It depends
Common DSCR thresholds and what they mean
Lender thresholds are commonly about 1.0 to 1.25 and vary by lender, program and borrower. The rows below describe what a ratio means for the property’s cash, not whether a loan will be approved.
| DSCR | What it means | How it is commonly viewed |
|---|---|---|
| Below 1.00 | The income does not cover the payment; the owner makes up the difference | Many programs do not lend at this level, and those that do usually ask for stricter terms, such as a larger down payment. |
| 1.00 | The income exactly covers the payment, with no cushion | Often discussed as a floor for rent ÷ PITIA programs; one vacancy or repair creates a shortfall. |
| About 1.10 to 1.20 | A modest cushion | Meets some programs’ minimums; the terms may still depend on credit and the down payment. |
| 1.25 or more | Income at least 25% above the payment | A commonly cited comfortable level, often used for commercial and multifamily loans. |
Because lenders measure DSCR differently, the same property can pass one lender’s test and fail another’s, as the two ratios in the worked example show. Ask which income, expenses and payment a lender uses.
Compare ratios
DSCR vs. DTI vs. LTV
Lenders look at several ratios. DSCR looks at the property; the others look at the borrower and at the size of the loan.
| Ratio | Formula | What it measures | Where it is commonly used |
|---|---|---|---|
| DSCR | Property income ÷ loan payment | Whether the rental income covers the debt | DSCR (rental-income) loans, commercial and multifamily loans |
| DTI (debt-to-income) | Borrower’s monthly debt payments ÷ gross monthly income | Whether the borrower’s own income can carry all of their debts | Conventional, FHA and other loans that verify personal income |
| LTV (loan-to-value) | Loan amount ÷ appraised value or price | How much of the property is financed, and how much equity protects the lender | Almost every mortgage; investment loans often require more equity |
Each lender sets its own limits for every ratio, and they interact: in some programs a lower LTV or stronger credit can offset a thinner DSCR.
Avoid these
Common DSCR mistakes
- Assuming every lender uses the same formula
- Some divide gross rent by PITIA, others NOI by principal and interest. The two can differ a lot for the same property, as the worked example shows.
- Using a hoped-for rent
- Lenders usually rely on a signed lease or an appraiser’s market rent estimate. If your rent assumption is higher, the lender’s ratio will be lower than yours.
- Forgetting insurance and HOA dues
- PITIA includes taxes, insurance and association dues. A condo with high HOA dues can fail a ratio that a house at the same rent passes.
- Treating a passing ratio as profit
- A rent ÷ PITIA ratio just above 1.00 leaves little or nothing for vacancy, repairs or management. Check the NOI method and the cash flow as well.
- Ignoring the rate
- A higher rate raises the payment and lowers DSCR. Test the ratio at a rate above the one you expect.
- Testing only the first year
- Taxes and insurance can rise after a purchase. A property near the threshold today may fall below it later.
FAQ
DSCR questions
What is a good DSCR for a rental property?
A DSCR above 1.00 means the income covers the payment. Lenders commonly look for about 1.0 to 1.25, depending on the lender, the program and the borrower, and many investors prefer a cushion of 1.20 to 1.25 or more under the NOI method. A higher ratio leaves more room for vacancies and repairs.
What is a DSCR loan?
An investment property mortgage that a lender qualifies mainly on the property’s rental income rather than the borrower’s personal income. Terms, minimum ratios and costs vary by lender; a licensed loan originator can explain the options available to you.
Is DSCR calculated with gross rent or with NOI?
Both are used. Many rental-income loan programs divide the gross monthly rent by PITIA, while commercial lenders and the MyInversorAI app divide NOI by annual debt service. The calculator shows both so you can see the difference.
What does PITIA mean?
Principal, interest, taxes, insurance and association (HOA) dues: the full monthly payment on a mortgaged property.
Can a DSCR loan have a ratio below 1.0?
Some programs allow it, usually on stricter terms such as a larger down payment, and many do not. This calculator cannot tell you whether you would qualify; only a lender can.
How can a property’s DSCR go up?
In general, through more of the income a lender counts, a lower payment (a smaller loan, a longer term or a lower rate) or lower costs inside the ratio, such as insurance or HOA dues. Each change to a loan has its own costs and trade-offs.
