What is this calculator?
A lender-style affordability estimate that ties income, debts, and housing costs (PITI) into a safe monthly payment range. For related decisions, compare with Calorie (TDEE) Calculator, BMI Calculator, Refinance (Original Loan Amount), Crypto DCA Calculator.
How it works
Inputs map to common U.S. underwriting checkpoints: front-end and back-end DTI limits, plus housing-cost assumptions (taxes, insurance, PMI).
Example calculation
Example: $120,000/year income with $800/month other debts. A 28% front-end target implies about $2,800/month for housing (PITI). A 36% back-end target implies about $3,600/month total debt, keeping housing near $2,800/month. Takeaway: Use a conservative input set and treat that result as the real ceiling, not the best-case result.
When should you use this
- If your interest rate quote is above ~6.5%, stress-test a 0.5–1.0% increase and set your ceiling from the conservative case.
- If you plan to move within ~5 years, prioritize cash-flow safety and reserves over a higher headline purchase price.
- If DTI is near 36%+, compare “pay down debt” vs. “increase down payment” and see which unlocks more buying power.
When this may NOT be ideal
- If you do not have realistic property tax/insurance/HOA numbers for your area yet.
- If income is irregular and your lender will average multiple years or apply overlays.
Tips to get better results
- Run a conservative scenario (higher taxes/insurance and a slightly higher rate) and treat it as the ceiling.
- If DTI is tight, reduce revolving debt first; underwriting outcomes often improve quickly.
- Keep reserves in the plan—max approval can be fragile when escrow rises.
How We Calculate Results
Results combine DTI constraints with a housing-cost budget model. Mortgage payment estimates use amortization math for principal + interest; taxes and insurance are treated as budget inputs.
Financial Decision Guidance
Approval is not affordability. Choose a payment that protects emergency savings and retirement contributions, then treat refinancing as optional upside.
Limitations of This Calculator
- DTI caps vary by lender and loan program; this is an estimate, not underwriting.
- Local taxes/insurance/HOA can materially change outcomes.
Common Mistakes to Avoid
- Targeting the maximum limit instead of a sustainable payment with buffer.
- Forgetting PMI/HOA/insurance increases and being surprised by escrow adjustments.
- Assuming a refinance is guaranteed; qualify at today’s rate first.

Commercial Real Estate DSCR FAQ
What is a good DSCR for a commercial loan?
Many commercial lenders prefer DSCR around 1.25+; below that, approval and pricing typically get harder. If your DSCR is tight, the fastest levers are increasing NOI (rent, occupancy, expense control) or reducing the loan amount/down payment.
How does NOI affect my commercial loan amount?
Higher NOI supports a larger loan because DSCR is fundamentally a cash-flow coverage test. Underwriting usually uses stabilized NOI, so one-time spikes rarely count the way recurring lease income does.
Can I get a commercial loan with no down payment?
A true “no down payment” commercial loan is uncommon; expect meaningful equity (often 20–35%+) in most bank terms. Programs like SBA may allow lower down payments, but DSCR and documentation standards usually tighten, not loosen.
What is the difference between DSCR and LTV?
DSCR measures cash-flow coverage, while LTV measures collateral risk relative to property value. A deal can pass one and fail the other, so you typically need both adequate NOI and sufficient equity to qualify.

The DSCR Multiplier Effect
Use DSCR to sanity-check whether the property’s income can actually carry the proposed debt service. If DSCR is borderline, focus on lease stability and expenses before assuming a lender will “average it out”.
NOI Calculation for Affordability
Higher NOI supports a larger loan because DSCR is fundamentally a cash-flow coverage test. Underwriting usually uses stabilized NOI, so one-time spikes rarely count the way recurring lease income does.
NOI = Gross Rental Income - (Vacancy Allowance + Operating Expenses)
*Operating expenses include property taxes, insurance, maintenance, and management fees, but exclude mortgage interest or depreciation.
CRE Loan Capacity: DSCR vs. LTV (7.5% Rate, 20yr Terms)
| Property NOI | Max Loan (1.25x DSCR) | Max Loan (75% LTV) | Borrowing Limit |
|---|---|---|---|
| $150,000 | ~$1.24 Million | $1.50 Million | DSCR Constrained |
| $250,000 | ~$2.06 Million | $1.50 Million | LTV Constrained |
Commercial Real Estate Glossary
- DSCR (Debt Service Coverage Ratio)
- A measure of the cash flow available to pay current debt obligations. Calculated as NOI divided by total debt service.
- NOI (Net Operating Income)
- Total income from the property minus all reasonably necessary operating expenses.
- LTV (Loan-to-Value)
- The ratio of a loan to the value of an asset purchased. In CRE, 70-75% is a standard maximum.
- Capitalization Rate (Cap Rate)
- The rate of return on a real estate investment property based on the income that the property is expected to generate.
2026 DSCR Benchmarks by Asset Class
| Property Type | Target DSCR | Max LTV |
|---|---|---|
| Multi-Family (Apartments) | 1.20x - 1.25x | 75% - 80% |
| Retail / Office | 1.30x - 1.40x | 65% - 70% |
| Industrial / Warehouse | 1.25x - 1.35x | 70% - 75% |
How to Prepare for a CRE Loan Application
- Verify Your NOI: Ensure your income and expense statements are accurate and up-to-date.
- Check Market Cap Rates: Understand the valuation of similar properties in your area.
- Review Tenant Quality: Lenders look at the "stickiness" of your income; long-term leases are preferred.
- Factor in Vacancy: Most lenders assume a 5-10% vacancy rate regardless of your current occupancy.
- Prepare Your Personal Financial Statement (PFS): Even for commercial loans, your global cash flow matters.
Best vs. Worst Case Scenarios
Realistic outcomes based on common decision paths.
Best Case Scenario
Outcome: You purchase a property safely 15-20% *below* your absolute maximum budget. This provides vital cash-flow buffer for unexpected home repairs, tax hikes, or life emergencies, allowing you to simultaneously fund your 401(k) and maintain high liquidity.
Worst Case Scenario
Outcome: You max out your debt-to-income (DTI) ratio. 45% of your gross income now goes to your mortgage. Your cash flow is suffocated ('house poor'), and a single missed paycheck or a sudden $5,000 roof repair forces you into high-interest credit card debt or even risks foreclosure.
Decision Matrix: Which path is right for you?
- Is your resulting Front-End DTI below 28%? → You are in the 'safe zone' for housing affordability according to major lenders.
- Are you projecting high maintenance/HOA costs? → Lower your target purchase price manually from the calculator's 'Max' output.
- Does buying drain your entire savings account? → It is highly inadvisable to close if you won't have a 3-month emergency fund left over after down payment and closing costs.
2026 CRE Trends: SBA 504 vs. Conventional Financing
Choosing the right loan structure is as important as the property itself. For owner-occupied businesses, the SBA 504 program often provides lower down payments (10%) compared to conventional CRE loans (25-30%). Use our CRE loan optimizer to see how different structures affect your long-term equity growth. If you're building a multi-family portfolio, our mortgage affordability tools can help you see how your personal debt affects your commercial borrowing limit.
Optimizing NOI for Maximum Borrowing Power
Commercial lenders focus on the "Net" in Net Operating Income. By reducing utility costs or streamlining maintenance, you can increase your NOI, which exponentially increases your loan eligibility. For investors balancing commercial assets with personal portfolios, consider our DCA growth model to manage the cash reserves needed for commercial down payments. If you're planning a major renovation, our rate sensitivity tool can show if a future refinance makes sense after the property value increases.
