Calculate your property’s DSCR
Property numbers
Debt-service-coverage ratio
Enter the property’s numbers to see its ratio.
Estimates only, based solely on what you enter. Lender guidelines differ — some divide rent by P&I alone rather than full PITIA, and thresholds vary by program. DSCR loans are business-purpose loans on non-owner-occupied property. This is a screening tool, not an offer, quote, or approval.
How the DSCR is calculated
The debt-service-coverage ratio (DSCR) is simply a property’s rental income divided by its debt obligation — typically the full housing payment including principal, interest, taxes, insurance, and any association dues (PITIA). A DSCR of 1.00 means the property’s income exactly covers its payment; 1.25 means it brings in 25% more than the payment.
DSCR loans use this ratio — not your personal income — to qualify an investment property, which is what lets investors scale beyond conventional debt-to-income limits. Most lenders look for a minimum ratio, often around 1.15 to 1.25, though some programs accept lower ratios with compensating factors. Guidelines vary widely, especially for short-term rentals, so use this as a screening tool and confirm specifics with a lender.

What a DSCR loan calculator tells you
A DSCR loan calculator helps real estate investors estimate the debt-service coverage ratio (DSCR) on a rental property — the key number that DSCR lenders use to qualify the loan. DSCR compares the property’s rental income to its debt obligation: in simple terms, it asks whether the rent covers the loan payment. A ratio of 1.0 means the income exactly covers the payment; above 1.0 means the property generates more than enough to cover it; below 1.0 means it falls short. The calculator above lets you enter your own figures and see the ratio instantly, using only what you type.
Because the calculator focuses on the property’s numbers, it gives you a fast read on whether a property is likely to qualify and how strong its coverage looks — the first practical step before pursuing a DSCR loan.
Entering your numbers
To estimate a property’s DSCR with the calculator above, you enter the property’s rental income and its loan payment (and, depending on the method, related housing obligations). If you don’t know the payment yet, the built-in P&I calculator works it out from a loan amount, rate, and term, and fills it in for you. The tool divides one by the other to produce the ratio instantly — no personal information required. It is built for quick scenario-testing: adjust the rent or payment and watch how the ratio moves, so you can see how a property performs before going further. For the full step-by-step method behind the number, see our guide to calculating DSCR.
What DSCR do lenders look for?
DSCR lenders generally want to see that a property’s income covers its debt, and many look for a ratio at or above a certain threshold — often around 1.0 or higher, though this varies by lender and program. A higher ratio signals a stronger, more comfortably-covered property, while a lower ratio may still be workable under some programs, sometimes with adjustments. Because guidelines vary, the practical answer for your property comes from matching its numbers to the right lender. Estimating your DSCR first tells you where you stand and which programs are realistic.
DSCR loans for investors
DSCR loans are a cornerstone of investment-property financing precisely because they focus on the property’s performance rather than the borrower’s personal income — which suits investors who may have complex tax returns or multiple properties. They work for single rentals, portfolios, and cash-out refinances to pull equity for the next purchase. Many investors also hold these properties in an LLC, which DSCR programs often accommodate.
