DSCR Calculator for Rental Properties

Find out in seconds whether a rental property cash-flows enough to qualify for a DSCR loan. Enter the rent and the full housing payment (PITIA) and the calculator returns your debt service coverage ratio, a pass/fail against the lender minimum you set, and exactly how much rent — or how much lower a payment — it would take to qualify. Switch to the NOI method for commercial and multifamily deals that underwrite net of vacancy and operating expenses.

About This DSCR Calculator

DSCR — debt service coverage ratio — is the single number a DSCR lender uses to decide whether a rental property qualifies on its own cash flow, without looking at your personal income. It compares the property's income to its debt payment: a DSCR of 1.0 means the property breaks even, above 1.0 means it produces surplus cash, and below 1.0 means the rent doesn't cover the loan. Most non-QM DSCR lenders want to see at least 1.20–1.25, though some will go down to 1.0 or even below with pricing adjustments or a 'no-ratio' program.

This calculator handles the two ways DSCR actually gets measured. The default DSCR-loan method matches how residential non-QM lenders underwrite: gross monthly rent divided by PITIA — principal, interest, taxes, insurance, and any HOA or association dues. The NOI method matches commercial and multifamily underwriting: net operating income (rent after vacancy and operating expenses) divided by annual debt service. Toggle between them depending on whether you're sizing a single-family or small-rental DSCR loan or underwriting a larger income property.

Beyond the ratio itself, the tool tells you what it would take to qualify. Set the lender's minimum DSCR and you'll see the highest payment that still clears it and the rent you'd need at your current payment — so instead of just learning a deal is short, you learn exactly how far. When you're ready to model the full loan, layer in extra principal, or structure seller financing and wraps around it, the GoFlexi calculator picks up where this leaves off.

Frequently Asked Questions

What is DSCR (debt service coverage ratio)?

DSCR is a property's income divided by its debt payment. It measures how comfortably the rent covers the loan. A DSCR of 1.0 means income exactly equals the payment (break-even); 1.25 means the property earns 25% more than the payment; 0.90 means the rent falls 10% short of covering debt. DSCR lenders use it to qualify a rental on its own cash flow instead of your personal income.

What DSCR do I need to qualify for a DSCR loan?

Most residential DSCR lenders want at least 1.20 to 1.25. Many will lend down to 1.0 (break-even) with a slightly higher rate or fee, and some offer 'no-ratio' or sub-1.0 programs (often down to around 0.75) at a meaningful pricing premium and lower leverage. Commercial and multifamily lenders typically require 1.20 to 1.35 depending on asset type and loan size. Set your lender's minimum in the calculator to see whether your deal clears it.

What rent do I need to qualify for a DSCR loan?

Work backward from the lender's minimum: the rent you need is the full payment times the minimum ratio. On the residential method that's PITIA × the minimum DSCR — so at a $1,920 PITIA and a 1.25 minimum you'd need $2,400 in monthly rent (1,920 × 1.25). On the NOI method it's annual debt service × the minimum, measured against NOI. This calculator solves it for you both directions: set your lender minimum and it shows the rent you'd need at your current payment and the highest payment that still clears the ratio, so you can see whether to push rent, raise the down payment, or buy down the rate.

How is DSCR calculated?

There are two common methods. The DSCR-loan (residential non-QM) method is gross monthly rent divided by PITIA — principal, interest, taxes, insurance, and HOA. The commercial method is net operating income (NOI) divided by annual debt service, where NOI is rent after vacancy and operating expenses and debt service is principal and interest only. This calculator does both — switch methods at the top.

What is PITIA?

PITIA stands for Principal, Interest, Taxes, Insurance, and Association dues (HOA). It's the full monthly cost of owning the financed property. Residential DSCR lenders use PITIA as the denominator because it captures everything the borrower must pay to keep the property and the loan current, not just the mortgage's principal and interest.

What is a good DSCR?

Above 1.25 is generally considered strong and gives you the widest choice of lenders and best pricing. 1.0 to 1.25 is workable but may limit options or cost more. Below 1.0 means the property doesn't cover its own debt — you'd be feeding it cash each month — and you'll need a no-ratio program, a larger down payment, or better terms to make it work. Higher is safer for both you and the lender.

My DSCR is below the lender minimum — what can I do?

You have a few levers: increase the down payment (a smaller loan means a smaller payment), buy down the interest rate, choose an interest-only period (lower payment raises DSCR), shop for cheaper insurance (property taxes are largely fixed for a given property, though you can appeal an over-assessment), raise the rent (or use market rent if it's above current rent), or find a lender with a lower minimum or a no-ratio program. The calculator shows the highest payment and the rent that would clear your target ratio, so you can see which lever closes the gap.

Does a DSCR loan use my personal income or DTI?

No. The defining feature of a DSCR loan is that it qualifies on the property's cash flow, not your personal income, tax returns, or debt-to-income ratio. That's why investors use them to scale past the point where conventional financing caps the number of mortgages. Your credit score and down payment still matter for rate and leverage, but the DSCR is what drives the approval.

Can I use a DSCR loan with seller financing or a seller-carried second?

Not directly — seller financing isn't a DSCR loan. When a seller carries the note they set the terms themselves; there's no lender running a DSCR test, so the ratio is something you'd check for your own safety, not a qualification hurdle. The two only intersect when you stack them: a senior DSCR loan in first position with a seller-carried second behind it. In that case the DSCR lender controls the structure — many cap combined loan-to-value (CLTV), some disallow subordinate seller financing outright, and others require the seller second's payment to be counted in debt service, which lowers your DSCR. If you're stacking, add the second's payment into the payment field here to see the coverage your lender will actually underwrite. A separate and common play is to buy with seller financing now and refinance into a DSCR loan at the balloon — there the DSCR becomes an exit test: will the rent qualify when you need to refi out.

What's the difference between residential and commercial DSCR?

Residential DSCR loans usually use gross rent divided by PITIA — a simple, generous measure that doesn't subtract operating costs from the income side. Commercial and multifamily underwriting uses net operating income (rent minus vacancy and all operating expenses) divided by principal-and-interest debt service, which is stricter because it accounts for the cost of running the property. The same deal will often show a higher DSCR under the residential method than the commercial one. Use the NOI method here when underwriting larger income properties.

Should vacancy and operating expenses factor into DSCR?

It depends on the lender. Most residential non-QM DSCR lenders ignore vacancy and operating expenses and use gross rent over PITIA. Commercial and multifamily lenders always net them out via NOI. Even if your lender uses the gross method, it's worth running the NOI method to understand the property's real coverage — a deal that qualifies on paper at 1.25 gross can be much thinner once vacancy and expenses are counted.
