Two calculators, each answering a different question about the same deal.

The DSCR calculator asks whether the property can carry the debt. The payment calculator asks what that debt costs each month and over the life of the loan. Between them you can test a commercial scenario in a few minutes and find out whether the loan amount you have in mind is realistic before anyone underwrites anything.

Both produce estimates. Neither produces an approval, and neither produces a quote.

DSCR is the debt service coverage ratio: the property's net operating income divided by its annual loan payments. DSCR is a central number in commercial underwriting, and for many lenders it is the figure that drives whether a transaction works at all — though how it is weighted varies by lender, property, borrower, and transaction.

You enter gross monthly rent, monthly operating expenses, the loan amount, an interest rate assumption, and the amortization period in years. There is an interest-only toggle if you want to test that structure.

The calculator returns three things: annual NOI, the estimated monthly payment, and the resulting DSCR.

Two things to know about the inputs. First, the calculator treats the rent figure you enter as income actually collected — it has no separate vacancy field. If the property has vacancy or credit loss, reduce the rent figure before entering it, because a lender will. Second, operating expenses should reflect what the property actually costs to run: taxes, insurance, utilities you pay, maintenance, and a management fee. Many lenders add a management fee whether or not you pay one, so leaving it out can make your DSCR look better here than it does in a lender's file; expense treatment varies by lender, property, borrower, and transaction.

The payment calculator isolates the cost of the loan itself, without the property income side.

You enter the loan amount, an interest rate assumption, and the amortization period in years, with an interest-only toggle. It returns the estimated monthly payment, total interest over the term entered, and total cost.

Its most useful function is comparison. Run the same loan amount at two amortization periods and the monthly difference is immediately visible — as is the total interest difference, which usually moves in the opposite direction. Run it with interest-only on and off to see what an interest-only period does to monthly cash flow and to the amount still owed later. That trade-off is one of the more consequential structuring decisions in a commercial loan, and seeing both sides of it in numbers is more useful than a description of it.

The DSCR reading. The calculator labels the result in three bands. Below 1.00 it reads *Below break-even* — the property's income does not cover the loan payment at the figures entered. Between 1.00 and 1.25 it reads *Marginal coverage* — income covers the payment with little cushion. At 1.25 and above it reads *Strong coverage*.

These labels describe the calculation, not any lender's requirement. Coverage expectations vary by lender, property type, and transaction, and a ratio that one lender is comfortable with on stabilized multifamily may not clear on a specialty asset. Use the bands as orientation, not as a threshold to pass.

A lender's number is often lower than yours. Underwriters build their own NOI, and many apply a vacancy factor, add a management fee, and reserve for replacements — each of which reduces NOI and therefore reduces DSCR. These adjustments vary by lender, property, borrower, and transaction. If your calculated coverage is only slightly above where you want it, treat that as thin rather than sufficient.

Solve backwards when coverage is short. If DSCR comes in low, the calculator is telling you the loan amount is too large for the income *at the assumptions entered*. There are usually several levers: a smaller loan amount, a longer amortization, an interest-only period, higher income, or lower expenses. Lower the loan amount until coverage improves and you have found what the property actually supports today — which is a genuinely useful number to walk into a conversation with.

On the rate field. We do not publish rates and cannot tell you what yours would be — pricing comes from a lender, on a specific file, after review. Enter an assumption and, more importantly, test a range. Running the same deal across several rate assumptions shows you how sensitive your coverage is to pricing, which is more informative than any single result.

A calculator result is an estimate produced from figures you supplied. It is not an approval, not a pre-approval, not a commitment, and not a quote.

Nothing here has been reviewed by a lender. No underwriter has looked at the property, verified the income, ordered an appraisal, or examined the borrower. The calculators do not know your credit, your liquidity, your entity structure, the property's condition, its lease expirations, or its market — all of which affect whether a loan is available and on what terms.

The practical use is directional. These tools tell you whether a deal is roughly in range, which structures are worth exploring, and what your loan amount would need to look like for the income to work. That is genuinely valuable early on. What they cannot do is tell you that a lender will say yes.

Q Commercial Capital is a mortgage brokerage and does not lend its own funds. All financing is subject to lender approval, and terms vary by lender, property, borrower, and transaction.

If the numbers look workable, the next step is a scenario review, where the figures get tested against what lenders are actually doing for your asset type and structure rather than against a formula.
