How to calculate DSCR
The debt service coverage ratio is gross monthly rent divided by the total monthly payment. The payment must include everything, not just principal and interest. Lenders abbreviate the full figure as PITIA, which stands for principal, interest, taxes, insurance and association dues.
DSCR = Gross Monthly Rent divided by PITIA
A property that rents for $2,400 with a total payment of $2,000 has a DSCR of 1.20. The rent covers the payment with twenty percent of headroom. Investors who calculate the ratio using only principal and interest get a flattering number that the lender will not agree with.
What DSCR you need to qualify
| DSCR | Interpretation | Typical treatment |
|---|---|---|
| 1.25 and above | Comfortable margin over the payment | Best pricing tier |
| 1.00 to 1.24 | Rent covers the payment | Standard qualification |
| 0.75 to 0.99 | Rent falls short of the payment | Reduced leverage, higher rate |
| Below 0.75 | Material shortfall | Generally needs more down payment |
The mistakes that inflate your DSCR
- Using principal and interest only and omitting taxes, insurance and HOA dues
- Using asking rent rather than the appraiser supported market rent
- Using short term rental projections when the program qualifies on long term market rent
- Ignoring that a larger cash out amount raises the payment and lowers the ratio
Improving a ratio that does not clear
There are only three levers. Increase the rent, reduce the loan amount by putting more down, or reduce the payment by taking an interest only structure where the program allows it. Interest only is the most common fix because it lowers the payment without requiring additional capital at closing.
If the ratio still does not work, the property may simply be priced above what its rent supports. That is useful information to have before the appraisal rather than after. Full terms are on the DSCR rental loan page.
