DSCR Calculator
Estimate the debt service coverage ratio lenders use to underwrite investor and rental property loans, and see whether the deal clears a typical lender minimum.
DSCR

Annual debt service

NOI cushion vs payment
$2,302
Underwriting check
DSCR is positive but thin. Many DSCR lenders look for at least 1.20x; some go lower with offsetting reserves or rate adjustments.
Monthly debt service
$1,878
Required NOI for minimum

Debt service coverage ratio is annual NOI divided by annual mortgage payments. DSCR investor loans size and price the loan based on the property income, so the ratio drives both qualification and pricing.

How this calculator works
What this page estimates
This DSCR Calculator is built to give a quick, browser-based estimate for dscr. Estimate the debt service coverage ratio lenders use to underwrite investor and rental property loans, and see whether the deal clears a typical lender minimum. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.
Calculation approach
The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.
Example workflow
For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.
Practical checks
- Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
- Run a low, base, and high case when the inputs are estimates.
- Check the related calculators below when the next decision depends on a different assumption.
How to interpret the dscr result
Best use
Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.
Cross-check
Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.
Watch for
Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.
This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.
Before relying on this dscr estimate
Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.
Confirm source numbers
Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.
Separate cash flow from total cost
A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.
Run conservative cases
Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.
Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.

How to Use
- Enter the monthly rent, vacancy assumption, and recurring monthly operating expenses.
- Add the loan amount, interest rate, and term you expect on the investor loan.
- Set the lender minimum DSCR — most non-owner-occupied DSCR loans require at least 1.10 to 1.25x.
- Review DSCR alongside annual NOI, annual debt service, and the NOI cushion versus the lender minimum.
Frequently Asked Questions
What is DSCR?
DSCR — debt service coverage ratio — is annual net operating income divided by annual mortgage payments. A 1.25x DSCR means NOI covers the loan payment 1.25 times over.
What DSCR do lenders typically want?
Many DSCR investor loans require at least 1.20 to 1.25x. Some programs allow 1.00x, occasionally lower with rate adjustments, larger reserves, or limited cash-out.
Is DSCR the same as cash flow?
No. DSCR is a ratio that compares NOI with debt service. Cash flow is the dollar amount left over after debt service. A 1.25x DSCR can be a small or large dollar cushion depending on property size.
Should I include taxes and insurance in DSCR?
Most lenders calculate DSCR on a PITIA basis, which includes principal, interest, taxes, insurance, and association dues. This calculator separates the loan payment so you can include taxes and insurance in operating expenses.
Can DSCR replace personal income for qualification?
On true DSCR investor loans, yes. Lenders qualify based on the property's income coverage rather than the borrower's W-2 income, which is why the ratio matters so much for non-owner-occupied financing.
