DSCR calculator

Debt service coverage ratio compares a property's rent to its own payment. It is the single number most investor property loans qualify on — not your income, not your tax returns, the property's.

Indicative arithmetic on the numbers you enter. It is not a quote, a pre-qualification or any specific lender's calculation — programs differ on whether taxes, insurance, HOA and vacancy belong in the denominator, and on whether the rent figure comes from a lease or an appraiser's estimate. Lender pages carry each lender's own published criteria and the date it was verified.

What DSCR is and how it's computed

DSCR = Gross Monthly Rent ÷ Monthly PITIA, where PITIA is Principal + Interest + Taxes + Insurance + Association dues. A property renting for $2,450 with a $1,960 PITIA has a DSCR of 1.25. The same property renting for $1,800 against that payment has a DSCR of 0.92. Nothing about the borrower — income, employment, tax returns — enters the calculation. It measures whether the property's own rent covers its own debt.

How it's used in an underwriting decision

A DSCR loan qualifies the deal on this ratio instead of a debt-to-income calculation. Lenders set a minimum — commonly somewhere at or below 1.00 — and price better as the ratio climbs, since a higher ratio means more cushion if the rent dips or a vacancy hits. A property below a lender's floor isn't automatically dead: a larger down payment, an interest-only structure, or a different lender's threshold can still make it work. Each lender's actual minimum DSCR and how it prices around that minimum is published, with a verification date, on that lender's own page.

What this ratio doesn't capture

  • Vacancy, turnover and true operating costs. DSCR uses gross rent, not net cash flow. It doesn't subtract vacancy, management fees, maintenance or capital reserves — the cash flow calculator does that.
  • Whether the rent figure is real. On a vacant or newly purchased property, the rent input is an appraiser's market-rent estimate, not a signed lease. That estimate can be optimistic or conservative depending on the comps used.
  • Return on your cash. DSCR says nothing about how much you put in or what you get back on it — that's cash-on-cash return, not DSCR.
  • Rate risk on a floating loan. This tool assumes a fixed rate for the life of the payment. A floating-rate bridge or hard money loan needs the rate cap calculator instead.
