Your DSCR
Enter your monthly rent and PITIA inputs to calculate your DSCR ratio.
Estimates only. Final terms via underwriting.

How to use this calculator
- 1
Enter monthly gross rent
Use your current lease amount, or — for vacant properties — an appraiser-estimated market rent. For short-term rentals, use trailing 12-month gross STR income averaged to a monthly figure.
- 2
Enter monthly PITIA
PITIA is principal + interest + property taxes + homeowners insurance + HOA dues (if any). Estimate PITI first, then add taxes and insurance on an annualized basis divided by 12.
- 3
Read your DSCR ratio
The ratio is rent divided by PITIA. 1.0 means rent covers the payment exactly. Above 1.0 means cash flow after debt service. 1.25+ generally qualifies for best pricing tiers.
- 4
Check qualifying programs
DSCR 1.0+ qualifies for standard DSCR programs. DSCR 0.75–0.99 routes to Sub-1 DSCR (LTV reduction vs. standard pricing). DSCR below 0.75 routes to No-Ratio DSCR (tighter LTV caps). If credit is the constraint instead of cash flow, Easy 50 has no minimum DSCR or credit score, capped at 50% LTV.

What this DSCR calculator actually tells you
Every investment-property loan we write starts with one number: DSCR — debt service coverage ratio. It's the single most important qualification metric in non-QM investor lending, and unlike personal-income loans, it's the property that has to qualify, not you. This calculator runs the same math we use in underwriting: monthly gross rent divided by monthly PITIA. A DSCR of 1.0 means rent exactly covers the payment. Anything above 1.0 is positive cash flow after debt service. Anything below 1.0 means the property has negative cash flow monthly — you can still qualify for a sub-1 DSCR ratio loan, but rates are higher.
When investors actually use this tool. Most people pull it up in three moments. First: pre-offer, when you're sizing a deal and need to know whether the rents support the financing before you waste an inspection. Second: at the cash-out refi stage, where DSCR determines your maximum LTV and your pricing tier. Third: when you're reverse-engineering an offer — given your target DSCR (say, 1.25 to land in our best pricing tier), what's the highest purchase price the rents can support?
What to do with the result. A DSCR of 1.25 or higher generally lands in our best-pricing tier on standard programs. Between 1.0 and 1.25 still qualifies for standard DSCR, which is the most common. Between 0.75 and 1.0 routes to our Sub-1 DSCR program (typically a 5% LTV reduction). Below 0.75, our No-Ratio DSCR program is available with tighter LTV caps. If credit is the constraint rather than cash flow, our Easy 50 program has no minimum DSCR and no minimum credit score (capped at 50% LTV) — useful for properties with strong appreciation upside that don't pencil on rent alone. If the number you got here doesn't quite work, send us the scenario anyway. We close over 95% of applications we start because we underwrite the deal, not the box.
Questions
DSCR calculator FAQs
DSCR (Debt Service Coverage Ratio) is the primary qualification metric for investment-property loans. It measures whether a property’s rental income covers the mortgage payment. A DSCR of 1.0 means rent exactly covers PITIA. Above 1.0 is cash flow after debt service; below 1.0 is a loss. Lenders use DSCR to qualify investment-property borrowers without looking at personal tax returns.
