Understanding Your Commercial Mortgage Calculator Results
When you use the Commercial Mortgage Calculator, you get key numbers like monthly payment, debt service coverage ratio (DSCR), loan-to-value (LTV), and cap rate. These values aren't just figures—they tell you whether a property is a good investment and whether lenders will approve your loan. This guide explains what different ranges mean and what actions you should take.
Monthly Payment Ranges
Your monthly payment is the amount you owe each month. It depends on the loan amount, interest rate, and amortization period. Here’s how to interpret different payment levels:
| Monthly Payment Range (per $100,000 borrowed) | What It Means | What to Do |
|---|---|---|
| Under $600 | Very low payment relative to loan size. Typically indicates a low interest rate and/or very long amortization (30 years). Great for cash flow but you’ll pay more interest over time. | Consider investing the savings. Check if the loan has a balloon payment—if the term is shorter than amortization, you’ll owe a lump sum later. See How to Calculate Commercial Mortgage Payments for details. |
| $600 – $900 | Moderate payment. Common for 20–25 year amortization at typical interest rates (5–7%). Good balance between affordability and total interest cost. | This is often a solid target. Ensure the property’s net operating income (NOI) covers the payment with a DSCR above 1.25. |
| $900 – $1,200 | High payment. Usually from short amortization (15 years) or higher interest rates (7–9%). Reduces cash flow but builds equity faster. | Check the property’s income. If NOI is strong and you want to own the building debt-free sooner, this may work. But lenders may require higher DSCR. |
| Over $1,200 | Very high payment. Could signal a high interest rate, short loan term, or large loan amount. High risk of cash flow strain. | Re-evaluate the deal. Consider a larger down payment to lower the loan amount, or negotiate a lower rate. Explore options like multifamily property loans which sometimes have better terms. |
Debt Service Coverage Ratio (DSCR)
DSCR measures your property’s net operating income divided by total debt payments. Lenders typically require at least 1.25. Here’s what different DSCR values mean:
| DSCR Range | Implication | Action |
|---|---|---|
| Below 1.0 | Property income is less than debt payments—negative cash flow. Lenders will reject the loan. | Increase down payment, find cheaper financing, or improve property income. Avoid buying unless you can cover the deficit. |
| 1.0 – 1.25 | Barely covers debt. Most lenders require a minimum of 1.25, so you may not qualify if above 1.0. | Try to boost NOI by raising rents or cutting expenses. Or negotiate a lower interest rate or longer amortization to reduce payments. |
| 1.25 – 1.4 | Comfortable coverage. Many lenders will approve, especially for strong property types like office or retail. | Good sign. Ensure you maintain reserves for vacancies or repairs. Use the calculator to test scenarios. |
| Above 1.4 | Strong cash flow with plenty of cushion. Attracts lenders and may allow for larger loan amounts. | Consider leveraging the property further or refinancing to pull out equity. Learn more about commercial mortgage basics. |
Loan-to-Value (LTV)
LTV compares the loan amount to the property value. Lower LTV means more equity. Typical commercial LTV caps are 65–75%.
| LTV Range | Meaning | Advice |
|---|---|---|
| Below 65% | Low leverage – you have at least 35% equity. Lower risk for lender; easier to get approved and better rates. | This is conservative. You may want to use more leverage to increase returns, but only if cash flow allows. |
| 65% – 75% | Standard leverage. Most commercial loans fall here. Reasonable risk for both borrower and lender. | This is typical. Ensure DSCR is above 1.25 to compensate for moderate leverage. |
| Above 75% | High leverage. Harder to get financing; may require higher DSCR or personal guarantees. Higher risk. | Only consider if the property has extremely strong income. Otherwise, increase your down payment. |
Capitalization Rate (Cap Rate)
Cap rate is NOI divided by property value. It shows the expected return without debt. Lower cap means higher property price relative to income.
| Cap Rate Range | Implication | Action |
|---|---|---|
| Under 5% | Low cap rate – property is expensive relative to income. Common in high-demand areas. You’re likely paying for appreciation potential. | Rely on property value growth. Make sure the market is appreciating. Higher risk if interest rates rise. |
| 5% – 8% | Moderate cap rate – typical for stable commercial properties. Balanced income and value. | Good target for a steady cash flow investment. Compare with local market averages. |
| Above 8% | High cap rate – property is cheaper relative to income. Could signal higher risk (e.g., older building, weak location). | Investigate why the cap is high. It might be a deal or a lemon. Use the payment formula to model worst-case scenarios. |
Putting It All Together
Your ideal commercial mortgage results depend on your goals. A low monthly payment and DSCR above 1.4 with conservative LTV (65%) means a safe, stable investment. Higher payments might be acceptable if you plan to flip or refinance quickly. Always run multiple scenarios on the calculator and talk to a lender.
