Loan Coverage Ratio Calculator

The loan coverage ratio tells a lender whether your property generates enough income to comfortably make the mortgage payment. This calculator compares NOI to annual debt service against a target coverage ratio.

How the math works

Loan Coverage Ratio (often called DSCR for real estate) measures how comfortably property income covers the mortgage. A 1.25 ratio means NOI is 25% bigger than the mortgage payment — a typical lender minimum for stabilized commercial and investment properties.

Stricter lenders require 1.30–1.40 on thin-margin or risky properties. Short-term rentals and owner-occupant DSCR loans sometimes allow 1.00 or even no-ratio. Taxes and insurance are usually carved out for a strict P&I-only ratio; confirm with your lender.

How this calculator works

What this page estimates

This Loan Coverage Ratio Calculator is built to give a quick, browser-based estimate for loan coverage ratio. The loan coverage ratio tells a lender whether your property generates enough income to comfortably make the mortgage payment. This calculator compares NOI to annual debt service against a target coverage ratio. 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 loan coverage ratio 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 loan coverage ratio 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 annual Net Operating Income (gross rent minus all operating expenses, before mortgage).
Enter the monthly principal-and-interest payment.
Set the lender's target coverage minimum (1.20–1.25 is typical; 1.30+ for riskier deals).
Read your coverage ratio and whether it clears the target. See the max monthly payment the property would support at your ratio.

Frequently Asked Questions

Is this the same as DSCR?

Yes — Debt Service Coverage Ratio is the standard name in commercial and DSCR loan underwriting. 'Loan coverage ratio' is a broader term that sometimes includes T&I, but is most often used interchangeably with DSCR.

What counts as NOI for this ratio?

Effective gross income (gross rent less vacancy) minus operating expenses: property tax, insurance, management, repairs, utilities paid by landlord, HOA. Exclude mortgage principal and interest, depreciation, and capex.

What's a good coverage ratio?

1.25 is the long-standing conventional commercial minimum. 1.40–1.50 is comfortable. Below 1.0 means the property can't cover its own debt — a lender would either deny the loan or require personal-income ratio qualification.

Do lenders include T&I in debt service?

Policies vary. Some strict lenders use PITIA (principal, interest, tax, insurance, association) in the denominator, producing a stricter ratio. Others use only P&I (like this calculator by default). Always confirm with your lender.
