Investor Tool — Debt Service Coverage Ratio

DSCR Calculator

DSCR is the single number that decides most investment-property loans — gross monthly rent divided by the full monthly payment. This calculator returns the ratio instantly and explains what the result means for financing. It is an educational estimate, not a lender decision, and is intended to help you sanity-check a property before you take it to underwriting. For how the loan itself works, see the DSCR loan program.

What is PITIA?

What this means: Enter gross monthly rent and the full PITIA payment to generate an underwriting snapshot. DSCR = rent ÷ PITIA.

How DSCR Is Calculated

The formula is deliberately simple: DSCR = Gross Monthly Rent ÷ Monthly PITIA. PITIA is the complete housing payment — Principal, Interest, property Taxes, Insurance, and Association/HOA dues. The reason the full payment matters is that a property can have strong rent and still fail coverage once taxes, insurance, and dues are included. In condo-heavy markets this is the most common reason an otherwise healthy-looking deal underwrites tight.

A ratio of 1.00 means the rent exactly equals the payment. Above 1.00, the property produces surplus cash flow; below 1.00, the rent does not fully cover the obligation. Most capital sources reference a minimum DSCR and price leverage in tiers around it, but the specific threshold, whether they use lease rent or appraiser market rent, and how they treat vacancy all vary by source — which is why this tool is a starting point, not a decision.

Association dues are the variable investors most often forget to include. A unit with $3,200 rent and a $2,650 payment looks strong — until $900/month in dues moves the real PITIA to $3,550 and the ratio below 1.00. Use the built-in PITIA builder to capture every component.

How to Read Your Result

DSCR rangeWhat it generally signals
1.25 and aboveStrong, well-cushioned coverage; typically the widest program access and best pricing tiers
1.00 – 1.24Rent covers the payment with margin; financeable with many sources, often at adjusted leverage or pricing
0.75 – 0.99Slight shortfall; some programs still lend with offsetting strengths such as lower leverage or reserves
Below 0.75Significant shortfall; usually requires restructuring the payment or rent assumptions

These bands are general industry references for interpretation only — they are not Alpha Equity Lending program minimums or commitments, and no rate or approval is implied. Two capital sources can treat the same ratio differently. The value of knowing the number early is that it tells you which conversation you are having before you are under contract.

Using This by Market

The same formula behaves differently across Florida because the payment side changes. In Miami, high-rise association dues are the dominant ratio-compressor. In West Palm Beach, wind-insurance premium is usually the swing variable on detached and small-multifamily files. In Orlando, short-term-rental income is projected and haircut rather than taken from a lease, so the rent input itself is the moving part. Modeling the property with its real local carrying costs — not a generic estimate — is what makes the number meaningful.

DSCR Calculator — Frequently Asked Questions

What is a DSCR calculator?
A tool that divides a property's gross monthly rent by its full monthly PITIA payment to produce the debt service coverage ratio — the figure most investment-property lenders use to size a loan.
What does a DSCR of 1.00 mean?
It means the gross monthly rent exactly equals the full monthly payment. Above 1.00 the property produces surplus cash flow; below 1.00 the rent does not fully cover the obligation.
What is included in PITIA?
Principal, interest, property taxes, insurance, and association or HOA dues. Leaving out taxes, insurance, or dues is the most common reason a calculated ratio looks better than the real one.
What DSCR do I need to qualify?
It varies by capital source. Many programs reference a minimum around 1.00 to 1.25 and price leverage in tiers, but the exact threshold, rent basis, and vacancy treatment differ by source. This calculator does not represent any specific program minimum.
Does this calculator reflect Alpha Equity Lending's actual terms?
No. It is an educational estimate only. It does not reflect any lender's specific methodology, minimum, leverage, or pricing, and it is not an offer, commitment, or approval. Confirm any scenario with us directly.
Should I use lease rent or market rent?
Programs differ — some use the in-place lease, some the appraiser's market-rent opinion, and some the lower of the two. Use the figure you expect to be supportable, and confirm the basis with the capital source.
Why does my strong-rent property show a low DSCR?
Usually because the full PITIA is higher than expected once taxes, insurance, and especially association dues are included. The PITIA builder in this tool helps capture every component.
Can a property below 1.00 DSCR still be financed?
Sometimes. Certain programs lend below 1.00 with offsetting strengths such as lower leverage or larger reserves, while others do not. Treatment varies by source and profile.
