Debt Service Coverage Ratio (DSCR) is a rental property's gross rent divided by its monthly housing payment (PITIA). This tool estimates DSCR from the figures you enter — no rates, no qualification decision. Viador Partners is an investor-financing advisory and is not the lender.
Formula. PITIA = principal & interest + taxes + insurance + HOA/association dues. DSCR = monthly gross rent / PITIA, rounded to two decimals. A DSCR of 1.00 means the rent exactly covers the housing payment.
Interpretation (educational, not an approval signal). Many investor lenders look for a DSCR around 1.0–1.25, but minimums, rent treatment (especially for short-term rentals), reserves, LTV, FICO, property type, and prepayment structure vary materially by lender and program. This tool does not make a qualification decision.
Alternative definitions. Some lenders and commercial analyses use a net-operating-income (NOI) based DSCR (NOI ÷ debt service) rather than gross-rent ÷ PITIA. This calculator uses the common residential gross-rent ÷ PITIA convention. Lender overlays vary; this is not a qualification decision.
Hypothetical (not an offer). If a property had $3,000 monthly gross rent and $2,500 total PITIA, the DSCR would be 1.20. This illustrates the math only — it is not a quote, rate, or offer.
Worked example (illustrative, not an offer).
| Principal & interest | $1,450 |
| Property taxes | $300 |
| Insurance | $180 |
| HOA / association dues | $0 |
| PITIA | $1,930 |
| Monthly gross rent | $2,400 |
| DSCR ($2,400 ÷ $1,930) | 1.24 |
Working backward is often more useful: the rent needed for a target DSCR is the PITIA multiplied by that target. Here, a 1.25 DSCR needs about $2,413 a month in rent. Small loans and foreign national files have their own wrinkles; see DSCR loans under $100,000 and foreign national DSCR loans.
Divide the property's monthly gross rent by its monthly PITIA: principal and interest, property taxes, insurance and any HOA or association dues. For example, $2,400 rent divided by $1,930 PITIA is a DSCR of 1.24.
Many DSCR programs look for 1.0 or higher, meaning the rent at least covers the payment. A DSCR around 1.20 to 1.25 or above often qualifies for better leverage or pricing, and some programs allow a DSCR below 1.0 at reduced leverage. Requirements vary by lender and program.
Lenders commonly use the lower of the current lease rent and the appraiser's market rent estimate. Short-term rentals may be qualified on rental history or a projection, depending on the program. Rent treatment varies by lender.
The common residential DSCR divides gross rent by PITIA, so vacancy, repairs and management are not subtracted. Commercial and some portfolio lenders use a net-operating-income DSCR instead, which subtracts operating expenses first and produces a lower ratio.
Multiply the monthly PITIA by 1.25. With a $1,930 PITIA, the rent needed is about $2,413 a month for a DSCR of 1.25, or $1,930 for a DSCR of 1.0.
DSCR is a fast way to see where a deal stands, but the ratio alone doesn't decide anything — how a lender treats the rent (especially short-term rental), reserves, LTV, and credit all move the outcome.
