DSCR Calculator
Estimate an underwriting DSCR — and real cash flow, separately.
What this calculator helps you estimate
This calculator estimates a debt-service coverage ratio from qualifying rental income and applicable monthly housing debt, then models estimated investor cash flow separately using operating expense assumptions.
DSCR compares a property's qualifying rental income to its applicable housing debt. That ratio is how many lenders evaluate an investment-property loan — but it is not the same as the cash flow you keep. This calculator shows both figures side by side, and never mixes them.
Underwriting inputs
Qualifying rent and housing debt
Lenders differ in what they include in housing debt and how they determine qualifying rent. Enter the figures your scenario uses; results are educational estimates only.
Results
Underwriting DSCR
Interpretation
A DSCR of 1.33 means the qualifying rent exceeds the applicable housing debt with meaningful margin under these assumptions. Expressed another way, qualifying rent equals approximately 133% of the applicable housing debt.
Acceptable ratios vary by lender, investor, property type, occupancy, and rental strategy. This estimate is not an approval or a statement of program eligibility.
Investor analysis
Operating expense assumptions
These operating expenses are part of your investment analysis. They are separate from the underwriting DSCR above and are generally not deducted in a lender's ratio.
Results
Estimated property cash flow
Interpretation
After the operating expenses entered, this property produces positive estimated cash flow. A property can meet a lender's DSCR calculation and still produce weak or negative investor cash flow once operating expenses are included.
Loan qualification and investment performance are related measures, but they are not the same decision.
Understand the math
How this calculator works
DSCR compares a property's qualifying rental income to its housing debt — it's how many investment-property lenders decide loan eligibility. This calculator keeps that lender-facing DSCR figure clearly separate from your actual take-home cash flow, since the two are often confused.
Worked example
Qualifying rent $2,500/month; housing debt (PITIA) of $1,750 principal & interest + $250 taxes + $100 insurance = $2,100.
- DSCR = qualifying monthly rent ÷ monthly housing debt
- DSCR = $2,500 ÷ $2,100 = 1.19
DSCR ≈ 1.19 — rental income covers housing debt with roughly 19% cushion.
How to read your results
Interpretation guidance
- A DSCR above 1.0 means qualifying rent exceeds the housing payment used in the ratio.
- This DSCR figure does not subtract vacancy, maintenance, or management — that's why actual cash flow can differ from what the ratio implies.
- Lenders may require a specific minimum DSCR depending on the program, property type, and your credit profile.
- Compare this figure to the separate cash-flow estimate on the investment property calculator for the fuller picture.
Deeper answers
More questions about this calculator
How is DSCR calculated?
DSCR = qualifying monthly rental income ÷ applicable monthly housing debt. Housing debt commonly includes principal, interest, property taxes, insurance, and HOA dues, and the exact methodology varies by lender and program. Results are estimates for educational purposes only and are not a commitment to lend.
What DSCR do lenders require?
There is no universal requirement. Thresholds and pricing adjustments vary by lender, investor, property type, occupancy, rental strategy, credit profile, and market conditions.
Is DSCR the same as my actual cash flow?
No. Many DSCR calculations compare rent to housing debt without deducting vacancy, maintenance, management, or capital expenditures. A property can meet a lender's DSCR calculation and still produce weak investor cash flow.
Can I use short-term rental income?
Sometimes, depending on program guidelines. Where considered, lenders generally look for documented booking or operating history rather than a projection, and local restrictions or HOA rules may also apply.

How is DSCR calculated?
DSCR = qualifying monthly rental income ÷ applicable monthly housing debt. Housing debt commonly includes principal, interest, property taxes, insurance, and HOA dues, and may include flood insurance or other required housing expenses. The exact methodology varies by lender and program. Results are estimates for educational purposes only and are not a commitment to lend.
What DSCR do lenders require?
There is no universal requirement. Thresholds and pricing adjustments vary by lender, investor, property type, occupancy, rental strategy, credit profile, and market conditions. A higher ratio generally indicates stronger property cash flow relative to the debt.
Is DSCR the same as my actual cash flow?
No. Many DSCR calculations compare rent to housing debt without deducting vacancy, maintenance, management, capital expenditures, or other operating costs. A property can meet a lender's DSCR calculation and still produce weak or negative investor cash flow. That is why this calculator reports the two figures separately.
Can I use short-term rental income?
Sometimes, depending on program guidelines. Where short-term rental income is considered, lenders generally look for documented booking or operating history and third-party support rather than an investor's own projection. Local restrictions, HOA rules, and licensing also matter.
