DSCR Calculator for Rental Properties
See whether a rental's income covers the loan — and whether it clears a lender's minimum DSCR.
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.
Residential non-QM method: gross rent divided by the full housing payment (PITIA).
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 Flexi calculator picks up where this leaves off.
