If you're financing a rental property without handing over tax returns and W-2s, one number does almost all the talking: your DSCR. The debt service coverage ratio tells a lender whether a property earns enough rent to cover its own loan payment — and on a DSCR loan, that single figure can replace the entire personal-income underwriting process.
Knowing how to calculate DSCR before you make an offer is one of the highest-leverage skills a rental investor can have. It tells you in seconds whether a deal will qualify for financing, how much leverage you can pull, and whether the rent will actually carry the debt. Get it wrong and you chase properties that no lender will fund; get it right and you underwrite like the bank does.
This guide breaks down the DSCR formula, walks through real worked examples, and shows exactly what lenders count as income and debt. At Funded Capital, DSCR loans start at 6.0% with up to 80% LTV and require no income verification — so understanding this ratio is the key to getting funded fast.
What Is DSCR and Why It Matters
The debt service coverage ratio measures a property's ability to pay its own debt from the income it generates. In plain terms, it answers one question: does the rent cover the mortgage?
A DSCR of 1.0 means the property breaks even — rental income exactly equals the debt payment. Above 1.0, the property produces surplus cash after the loan is paid. Below 1.0, the property doesn't generate enough to cover its debt, and the gap has to come from the investor's pocket.
This is the entire foundation of a DSCR loan. Instead of underwriting your personal income, the lender underwrites the property's income. That's why DSCR financing is the go-to tool for self-employed investors, those who write off most of their earnings, and anyone borrowing through an LLC who can't easily document W-2 income.
How to Calculate DSCR: The Formula
The DSCR formula is straightforward:
DSCR = Net Operating Income ÷ Total Debt Service
For most residential rental underwriting, lenders use a simplified version based on monthly figures:
DSCR = Monthly Rental Income ÷ Monthly Debt Payment (PITIA)
PITIA is the part investors most often miscalculate. It stands for the full monthly housing payment — not just principal and interest. Here's what goes into it:
| Component | What It Includes |
|---|---|
| P — Principal | The portion of the payment reducing the loan balance |
| I — Interest | The cost of borrowing at your loan rate |
| T — Taxes | Monthly property taxes (annual ÷ 12) |
| I — Insurance | Hazard and, if applicable, flood insurance |
| A — Association dues | Monthly HOA or condo fees, if any |
If you only count principal and interest, your DSCR will look better than it really is — and your lender's number won't match yours. Always use full PITIA on the bottom of the equation.
Income: What Counts as Rent
On the income side, lenders use the property's gross monthly rent. For a tenant-occupied property, that's the lease amount. For a vacant or newly purchased property, lenders use market rent — typically supported by an appraiser's rent schedule (the Form 1007 or 1025).
Lenders use gross rent, not the cash left after expenses, for the residential DSCR calculation. Operating costs like vacancy, maintenance, and management are real and belong in your own deal analysis, but the standard DSCR underwriting ratio compares gross rent directly against PITIA. To model your own numbers quickly, run them through our loan calculator.
DSCR Calculation Examples
Numbers make this concrete. Here are three worked examples across common scenarios.
Example 1: A Cash-Flowing Rental
You own a single-family rental that leases for $2,400 per month. Your full monthly payment — principal, interest, taxes, insurance — comes to $1,850.
DSCR = $2,400 ÷ $1,850 = 1.30
A 1.30 DSCR means the property earns 30% more than its debt costs. This is a strong, easily financeable number that qualifies for the best DSCR loan terms.
Example 2: A Break-Even Deal
A condo rents for $1,900 per month. Principal and interest run $1,500, taxes add $250, insurance $90, and the HOA charges $60 — total PITIA of $1,900.
DSCR = $1,900 ÷ $1,900 = 1.00
This property breaks even exactly. Many lenders will still fund at a 1.0 DSCR, though often at slightly reduced leverage. It qualifies, but there's no cushion.
Example 3: A Shortfall
A property rents for $1,600 but carries a $1,950 monthly PITIA.
DSCR = $1,600 ÷ $1,950 = 0.82
At 0.82, rent covers only 82% of the debt payment. The investor would feed the property $350 a month. Most lenders decline at this level — but options exist, which we cover below.
What Is a Good DSCR?
Lenders generally sort DSCR into tiers, and where your deal lands drives both approval and leverage.
| DSCR Range | What It Means | Lender View |
|---|---|---|
| 1.25+ | Strong surplus cash flow | Best rates and highest LTV |
| 1.10 – 1.24 | Healthy cushion | Standard approval |
| 1.00 – 1.09 | Breaks even to slight surplus | Approvable, may cap leverage |
| Below 1.00 | Rent doesn't cover debt | Limited programs; lower LTV |
Most lenders set their baseline at a 1.0 to 1.25 DSCR. A ratio of 1.25 or higher unlocks maximum leverage and the strongest pricing. Funded Capital finances DSCR loans starting at 6.0% with up to 80% LTV, and we have programs for sub-1.0 deals at adjusted terms — so a thin ratio doesn't automatically kill the deal.
How to Improve a Weak DSCR
If your ratio comes in low, you have levers. A larger down payment reduces the loan balance and shrinks PITIA, lifting the ratio. A longer amortization or an interest-only period lowers the monthly payment. And buying right — negotiating a lower purchase price or targeting markets with stronger rent-to-price ratios — improves DSCR before you ever apply.
This is exactly why so many investors pair short-term and long-term financing. A common play is the BRRRR strategy: acquire and renovate with a fix-and-flip loan, raise the rent through improvements, then refinance into a DSCR loan once the property cash flows. The rehab forces both value and rent up, strengthening the ratio for the permanent loan.

Frequently Asked Questions
How do you calculate DSCR?
Divide the property's monthly rental income by its total monthly debt payment (PITIA — principal, interest, taxes, insurance, and association dues). For example, $2,400 in rent against a $1,850 payment gives a DSCR of 1.30. The annual version of the formula divides net operating income by total annual debt service, but residential lenders typically use the monthly gross-rent-to-PITIA version. Run your own numbers with our loan calculator.
What is a good DSCR for a rental property?
A DSCR of 1.25 or higher is considered strong and unlocks the best rates and highest leverage. Most lenders set their minimum somewhere between 1.0 and 1.25. A ratio of 1.0 means the property breaks even, and anything below 1.0 means rent doesn't fully cover the debt. Funded Capital finances DSCR loans starting at 6.0% with up to 80% LTV and offers programs for sub-1.0 deals at adjusted terms.
Does DSCR include taxes and insurance?
Yes. The debt payment in a DSCR calculation should be full PITIA — principal, interest, taxes, insurance, and any HOA or association dues — not just principal and interest. Leaving out taxes and insurance inflates your ratio and will cause your number to differ from the lender's. Always use the complete monthly housing payment in the denominator.
Can I get a DSCR loan with a ratio below 1.0?
Often, yes. While many lenders require at least a 1.0 DSCR, programs exist for properties that don't fully cover their debt — usually with a larger down payment or lower LTV to offset the risk. Funded Capital has options for sub-1.0 deals. You can also strengthen a weak ratio with more money down, longer amortization, or an interest-only structure. Apply now to see what your deal qualifies for.
What income is used to calculate DSCR?
Lenders use the property's gross monthly rent. For a leased property, that's the current lease amount; for a vacant or newly acquired property, lenders use market rent supported by an appraiser's rent schedule. The standard residential DSCR ratio compares gross rent directly to PITIA — operating expenses like vacancy and maintenance belong in your own deal analysis but aren't subtracted in the underwriting ratio itself.
