DSCR Loan Calculator

Reverse the DSCR formula to size the maximum loan a rental property can support. DSCR loans qualify the property, not the borrower's W-2 income — this calculator shows the loan amount your projected income will carry.

Reading the number

DSCR loans size the maximum loan to ensure projected rental income covers debt service by the lender's required ratio (commonly 1.20–1.25 for the best pricing). Some lenders use NOI; others use a stricter "rent − taxes − insurance − HOA" formula.

Effective rent at 5% vacancy: $3,040/mo. Annual T/I/HOA: $6,120. If the property won't appraise high enough to support this loan amount, LTV becomes the binding constraint instead.

How this calculator works

What this page estimates

This DSCR Loan Calculator is built to give a quick, browser-based estimate for dscr loan. Reverse the DSCR formula to size the maximum loan a rental property can support. DSCR loans qualify the property, not the borrower's W-2 income — this calculator shows the loan amount your projected income will carry. 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 loan 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 loan 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 gross monthly rent and an expected vacancy assumption.
Enter monthly taxes, insurance, and HOA — the property carrying costs the DSCR formula subtracts.
Enter the loan rate and term — most DSCR loans are 30-year amortization.
Enter the lender's minimum DSCR (commonly 1.20–1.25 for best pricing, 1.00 for stretch programs).
Read the maximum loan amount and the implied monthly P&I — your binding constraint is the lower of this and the LTV cap.

Frequently Asked Questions

How does a DSCR loan qualify a borrower?

Instead of pulling tax returns and W-2s, DSCR lenders qualify the deal by the property's projected income. Income (rent − taxes − insurance − HOA) ÷ debt service = DSCR. If DSCR meets the floor and the borrower clears credit and reserves, the deal funds.

What's a typical DSCR floor?

1.20–1.25 for the best pricing on a 30-year fixed. 1.00 (break-even) is available with rate adjustments. Some programs allow sub-1.00 ('no-ratio') with significant pricing premium.

Does DSCR use NOI or a different income figure?

DSCR loan underwriting commonly uses 'rent minus PITIA-not-debt' — gross rent minus taxes, insurance, HOA — rather than full operating NOI that includes management and maintenance reserves. Always confirm the exact formula your lender uses.

Can a DSCR loan use short-term-rental income?

Some lenders allow it using the lower of (1) actual trailing 12-month income or (2) market long-term rent. Most use long-term comps for safety. A few programs accept AirDNA-style projections for new acquisitions.
