A DSCR loan calculator computes the debt service coverage ratio of a rental property: annual net operating income (NOI) divided by annual debt service. DSCR lenders use this ratio, typically requiring 1.20 to 1.25, to qualify investment property loans without verifying the borrower's personal income.

DSCR equals NOI divided by debt service. First compute NOI: gross rental income minus vacancy allowance plus other income, minus all operating expenses (taxes, insurance, maintenance, management, HOA). Then divide annual NOI by the annual mortgage debt service (principal and interest, or PITI if the lender includes taxes and insurance). A DSCR of 1.15 means the property earns 15 percent more than its debt payments.

A DSCR of 1.25 or higher is generally considered bankable and qualifies for most DSCR loan programs. A ratio between 1.00 and 1.25 is tight: the property covers its debt but leaves little margin for vacancies or repairs. Below 1.00 means negative cash flow, which most lenders will not finance. These are general guidelines, and each lender sets its own minimum.

Most DSCR loan programs require a minimum ratio of 1.00 to 1.25. Common thresholds are 1.20 or 1.25 for standard rates, while some lenders accept 1.00 with a higher interest rate or larger down payment. Below 1.00, the property does not cover its own debt service and is rarely eligible.

DSCR (debt service coverage ratio) measures whether a rental property's income covers its own mortgage: NOI divided by debt service. DTI (debt-to-income ratio) measures a borrower's personal finances: monthly debt payments divided by gross monthly income. DSCR loans qualify the property, not the person, which is why they usually require no tax returns or employment verification.

NOI (net operating income) is effective rental income minus operating expenses. Effective income is gross rent minus a vacancy allowance plus other income such as laundry or parking. Operating expenses include property taxes, insurance, maintenance, property management, HOA dues, and utilities paid by the owner. Mortgage payments are not an operating expense: they are the debt service in the denominator.

It depends on the lender. Many DSCR lenders calculate debt service as PITI: principal, interest, property taxes, and insurance, because those are unavoidable costs of holding the property. Others use P&I only and treat taxes and insurance as operating expenses inside NOI. Both approaches are valid; the key is to match the convention your lender uses. This calculator supports both modes.

A DSCR below 1.0 means the property's net operating income does not cover its mortgage payments, so you must feed the property with outside cash every month. Most DSCR lenders will decline the loan or require a larger down payment and a higher rate. Options include raising rents, cutting expenses, increasing the down payment to shrink the loan, or negotiating a lower purchase price.

Raise the numerator or shrink the denominator. Raise NOI by increasing rents, reducing vacancies, adding other income, or cutting operating expenses. Shrink debt service with a larger down payment, a lower interest rate, or a longer amortization term. Even small changes compound: a 5 percent rent increase plus a 0.5 point rate reduction can move a 1.15 ratio above 1.25.

Break-even occupancy is the occupancy rate at which a rental property's income exactly covers its operating expenses plus debt service: (annual operating expenses + annual debt service - other income) divided by gross annual rent. If break-even occupancy is 85 percent, the property must stay at least 85 percent occupied to avoid losing money. Lower is safer.

Yes, that is the main appeal of DSCR loans: most programs do not require tax returns, pay stubs, or employment verification because qualification is based on the property's cash flow, not your personal income. Lenders still check your credit score, reserves, and the property appraisal, and investment experience can affect the rate.

They answer different questions. Cap rate (NOI divided by property price) measures the unleveraged return of the property itself. DSCR (NOI divided by debt service) measures whether the property can safely carry its mortgage. A high cap rate property with heavy leverage can still have a weak DSCR. Lenders care about DSCR; investors comparing all-cash returns care about cap rate.
