The DSCR formula is a straightforward calculation used primarily in residential and commercial real estate to determine the property’s ability to cover its debt obligations.
For residential properties (one to four units), the formula is:
Monthly Rent / PITIA = DSCR
PITIA stands for Principal, Interest, Taxes, Insurance, and any Association dues. If there are no association dues.
DSCR Example Calculation:
Consider if monthly rent is $1,750, and the housing payment (P.I.T.I.A) is $1,650. Divide the rent by the payment to get the DSCR ratio, which would be 1.06 in this example. Generally, lenders prefer a DSCR of 1:1 or greater.
Different lenders may have varying DSCR requirements:
Interest-Only Loans: Some lenders offer these loans where the DSCR falls below one, eliminating the principal from the calculation.Minimum DSCR: This varies by lender. Some might not require a DSCR, focusing instead on a larger down payment or a lower loan-to-value ratio.Lender Preferences: For favorable rates, many lenders require a DSCR of at least 1:1, with some accepting as low as 0.75 to 0.99.
Calculating DSCR accurately is now simpler with the use of specialized Excel calculators. These tools allow you to input principal, interest, taxes, insurance, and rent data to automatically compute your DSCR.
