How we build pro formas, calculate debt service coverage, and stress-test projections for SBA underwriting
The financial projection is where every element of the feasibility study converges into a single question: can this project generate enough cash flow to service its debt? The market analysis establishes demand. The competitive analysis validates pricing. The site assessment confirms physical viability. The financial projection takes all of those inputs and translates them into a multi-year income statement, a debt service calculation, and the DSCR that determines whether the loan gets approved.
Our financial modeling methodology follows one principle above all others: every number in the pro forma must be traceable to a market finding or an industry benchmark. A revenue projection that cannot point to its source in the market analysis is an assumption. An expense projection that cannot point to a published benchmark is a guess. Assumptions and guesses do not survive credit committee review.
There is no universal revenue projection model. Each property type has a different revenue structure, different performance metrics, and different data sources. The methodology must match the asset class.
| Asset Class | Revenue Model | Key Metric | Data Source |
|---|---|---|---|
| Hotel | Rooms x occupancy x ADR = room revenue + ancillary (F&B, parking, events) | RevPAR | STR comp set data |
| Self-storage | Rentable SF x occupancy x weighted avg rent/SF = storage revenue + ancillary (insurance, late fees, retail) | Revenue per occupied SF | CoStar, REIT operating data |
| Gas station | Gallons/day x fuel margin + inside sales/SF + car wash revenue + QSR revenue | Gallons per day, inside sales/SF | OPIS, NACS, DOT traffic |
| Restaurant | Seats x turns/day x avg check x operating days = food revenue + beverage revenue | Revenue per SF, avg check | Franchise Item 19, trade area comps |
| Multifamily | Units x occupancy x weighted avg rent = gross rental income + other income (parking, laundry, fees) | Effective rent per unit | CoStar, RentRange |
| Car wash | Wash count/day x blended RPC x operating days = wash revenue + membership revenue | Wash count, RPC | ICA, DOT traffic |
| Medical office | Providers x patients/day x net collection/visit x operating days | Revenue per provider | MGMA, payor fee schedules |
| Daycare | Licensed capacity x enrollment rate x weighted avg tuition by age group | Revenue per enrolled child | State licensing data, competitor surveys |
| Fitness center | Members x monthly dues + ancillary (PT, retail, upgrades) x 12 months | Revenue per member | Franchise Item 19, IHRSA data |
| Brewery/distillery | Production BBL x channel-weighted revenue/BBL + taproom food/events | Revenue per BBL by channel | Brewers Association, TTB data |
| Wedding venue | Events/year x avg revenue/event (rental + catering + services) | Revenue per event | The Knot data, competitor rate shopping |
| Glamping | Units x occupancy x ADR = accommodation revenue + experiences/activities | RevPAR (unit basis) | AirDNA, comp set rate shopping |
Each revenue model is built bottom-up from the market analysis, not top-down from a target. We do not start with a desired revenue number and work backward to find assumptions that support it. We start with the market data (traffic counts, comp set performance, demographic demand) and build forward to a projected revenue figure. If that figure does not produce an adequate DSCR, the project may not be feasible. That is a finding, not a failure of the model.
Operating expenses are projected using industry-specific benchmarks, adjusted for local cost factors. We never accept borrower-provided expense estimates without independent validation against published data.
| Expense Category | Benchmark Source | Typical Range (% of Revenue) | Local Adjustments |
|---|---|---|---|
| Labor / payroll | BLS wage data, franchise FDD, industry surveys | 25% to 65% (varies dramatically by property type) | State/local minimum wage, prevailing wage for skilled positions, labor market tightness |
| Utilities (water, gas, electric) | EIA regional rates, utility tariff schedules | 3% to 15% | Climate zone (HVAC load), local utility rates, equipment efficiency |
| Property taxes | County assessor, local mill rates | 5% to 15% | Assessment methodology, tax abatement programs, agricultural exemptions |
| Insurance | Industry loss data, carrier quotes | 2% to 6% | Location risk (coastal, flood zone, wildfire), construction type, claims history |
| Maintenance / repairs | BOMA benchmarks, property age analysis | 3% to 10% | Property age (older = higher), climate severity, construction quality |
| Management fee | Industry standard (even if owner-managed) | 3% to 10% | Property type, third-party vs owner-managed, economies of scale |
| Marketing | Industry surveys, franchise requirements | 1% to 5% | Competitive intensity, new vs established business, OTA commission rates |
| Reserves / replacement | Lender requirements, equipment lifecycle analysis | 2% to 5% | Equipment age, remaining useful life, franchise-mandated replacement schedules |
| Food cost (restaurants, hotels w/ F&B) | NRA benchmarks, franchise Item 19 | 25% to 38% of food revenue | Menu pricing, supplier contracts, commodity exposure |
| Franchise fees (if applicable) | FDD disclosure | 7% to 12% of gross revenue | Royalty + marketing fund + technology fees |
The management fee is always included, even for owner-operated businesses. This is a point of frequent disagreement with borrowers who plan to manage the business themselves and view the management fee as unnecessary. The fee must be included because the DSCR must demonstrate that the business can service its debt independent of the owner working for free. If the owner becomes incapacitated, the business must be able to hire a replacement manager and still cover its obligations. SBA lenders and processing centers routinely reject pro formas that omit management compensation.
The pro forma follows a standard commercial real estate income statement structure that credit officers are trained to read.
| Line Item | Calculation | Notes |
|---|---|---|
| Gross potential revenue | Maximum revenue at 100% occupancy/utilization | The theoretical ceiling; never achieved in practice |
| Less: vacancy / collection loss | Gross revenue x vacancy factor (5-15% depending on property type) | Accounts for physical vacancy, concessions, and uncollectable accounts |
| Effective gross income (EGI) | Gross revenue minus vacancy/collection loss | The realistic revenue baseline |
| Plus: other income | Ancillary revenue streams (parking, laundry, vending, late fees, etc.) | Often 3-10% of EGI; should not be overlooked |
| Total revenue | EGI + other income | Top line of the operating statement |
| Less: total operating expenses | Sum of all expense categories (see benchmarking above) | Itemized, not a single line; each category sourced independently |
| Net operating income (NOI) | Total revenue minus total operating expenses | The cash available to service debt, fund reserves, and provide owner return |
| Less: capital reserves | Annual reserve for equipment replacement, FF&E, etc. | Some analysts include reserves above the NOI line; we include it below for transparency |
| Adjusted NOI / cash flow available for debt service | NOI minus capital reserves | This is the numerator in the DSCR calculation |
We model the pro forma on two timescales. The annual pro forma covers Years 1 through 5 (or longer for projects with extended ramp periods) and provides the stabilized DSCR that drives the credit decision. The monthly pro forma covers the first 12 to 24 months and is essential for new construction, startups, and seasonal businesses where the annual average masks months of negative cash flow. A hotel that achieves 1.30x DSCR annually may operate below breakeven from November through February. The lender needs to see the monthly trajectory, not just the annual average.
The debt service coverage ratio is calculated as adjusted NOI (cash flow available for debt service) divided by total annual debt service. Total debt service includes all obligations the business must service from operating cash flow.
| SBA Program | Codified DSCR Minimum | Typical Lender Threshold | Notes |
|---|---|---|---|
| Standard 7(a) (>$350K) | 1.15x | 1.25x | Must be achievable within first two years per SOP 50 10 8 |
| 7(a) Small Loan (≤$350K) | 1.10x | Varies | Per Procedural Notices 5000-875701 and 5000-876777 |
| SBA Express | No SBA minimum | Lender discretion | Fully delegated; lenders apply own standards |
| SBA 504 | No formal SBA minimum | 1.20x to 1.25x (CDC-specific) | Each CDC sets its own threshold; confirm before modeling |
Total debt service means ALL debt. The most common DSCR error we encounter in studies from other providers is calculating DSCR against only the SBA mortgage while omitting equipment leases, lines of credit, seller carry-back notes, or partner distributions that are contractually required. If the business has $300,000 in annual SBA mortgage payments plus $80,000 in equipment lease payments, total debt service is $380,000. A $450,000 NOI produces a 1.50x DSCR against the mortgage alone but only 1.18x against total debt service. The second number is the real DSCR, and it is the one the lender must evaluate.
The base case DSCR answers the question "what happens if everything goes according to plan?" Sensitivity analysis answers the more important question: "what happens when it doesn't?"
We construct three standard scenarios for every feasibility study.
Base case: the most probable outcome derived from market data. This is the scenario the revenue and expense projections are calibrated to produce. It represents the median expectation, not the best case.
Optimistic case: assumes favorable conditions. Revenue 10% to 15% above base case (faster absorption, stronger pricing, better competitive positioning than projected). Expenses 5% to 10% below base case (efficient operations, favorable utility rates). This scenario is included for completeness and to show the upside potential, but no credit decision should be based on the optimistic case.
Pessimistic case: assumes adverse conditions. Revenue 15% to 25% below base case (slower absorption, competitive price pressure, economic softening). Expenses 10% to 15% above base case (labor cost increases, utility spikes, higher maintenance). This scenario is the one that matters for risk assessment. If the pessimistic DSCR remains above 1.0x, the project can survive adversity. If it drops below 1.0x, the lender must evaluate the probability and duration of the adverse scenario.
Beyond the three scenarios, we test individual variables to identify which assumptions have the greatest impact on DSCR. This tells the lender where the real risk lies.
| Variable Tested | Test Range | Property Types Most Affected |
|---|---|---|
| Occupancy / utilization | Base case minus 5, 10, 15, 20 percentage points | Hotels, self-storage, multifamily, glamping |
| Average rate (ADR, rent, ticket) | Base case minus 5%, 10%, 15%, 20% | Hotels, multifamily, restaurants, wedding venues |
| Absorption / ramp timeline | Base case plus 3, 6, 12 months to stabilization | Self-storage, new construction, startups |
| Labor cost | Base case plus 5%, 10%, 15% | Restaurants, daycare, hotels, medical offices |
| Fuel margin (gas stations) | Base case minus $0.05, $0.10, $0.15 per gallon | Gas stations |
| Interest rate (variable-rate debt) | Base case plus 100, 200, 300 basis points | All property types with variable-rate 7(a) debt |
| Membership churn (subscription models) | Base case plus 1, 2, 3 percentage points monthly | Car washes, fitness centers |
| Food cost ratio | Base case plus 2, 4, 6 percentage points | Restaurants, breweries with food service |
The output of single-variable testing is a sensitivity table that shows the DSCR at each test level. This table is one of the most referenced exhibits in the study by credit committees. It answers questions like "what occupancy does the hotel need to maintain a 1.15x DSCR?" or "how much can labor costs increase before the restaurant breaks even?" These breakeven thresholds give the lender concrete risk metrics rather than abstract scenarios.
For complex projects with multiple interdependent risk variables, we employ Monte Carlo simulation to quantify the probability distribution of DSCR outcomes. Rather than testing one variable at a time (which ignores the correlation between variables), Monte Carlo runs thousands of simulations where all key variables fluctuate simultaneously within their expected ranges.
The output is a probability distribution: "there is a 75% probability that DSCR will exceed 1.15x in Year 2" is a more informative risk statement than "base case DSCR is 1.35x." We use Monte Carlo simulation selectively for projects where the interaction between variables is significant: mixed-use developments with multiple revenue streams, seasonal businesses with weather-dependent demand, and projects in volatile markets where multiple adverse conditions may coincide.
Monte Carlo simulation is not standard in SBA feasibility studies. Most studies use the three-scenario plus single-variable approach, which is sufficient for straightforward transactions. We reserve Monte Carlo for complex projects where the standard approach does not adequately capture the risk profile, and when the additional analytical depth is warranted by the project's size and complexity.
The projection period is typically 3 to 5 years. Year 1 includes monthly detail. Years 2 through 5 are annual. The timeline extends beyond 5 years only for properties with unusually long stabilization periods (self-storage at 3+ years) or when the loan term demands it (504 debentures with 20 or 25-year terms may warrant a longer projection horizon).
Revenue growth assumptions are anchored to market evidence. We typically project 2% to 4% annual revenue growth beyond stabilization, which reflects a combination of rate increases (inflation-linked) and modest occupancy/utilization improvements. Growth assumptions above 4% require specific market justification (documented population growth above 3% annually, demonstrated supply constraints, contractual rate escalators). We do not project hockey-stick revenue growth because lenders do not believe it and SBA examiners flag it.
Expense growth assumptions are projected at 2% to 3% annually for most categories, with specific adjustments for known escalators (scheduled minimum wage increases, property tax reassessment triggers, insurance market hardening, franchise fee increases). Labor cost growth in the current environment is projected at 3% to 5% given the persistent tightness in service-sector labor markets across most U.S. metros.
The financial projection is not a standalone model. Every input traces back to the market analysis. The projected occupancy comes from the demand quantification model. The projected rate comes from competitive benchmarking. The absorption timeline comes from comparable transaction analysis. The expense ratios come from industry benchmarks adjusted for local conditions identified during the market analysis.
This traceability is what makes the financial projection defensible. A credit officer who questions the revenue projection can follow it back to the demand model. If the demand model is sound, the revenue projection is sound. If the demand model has a gap, the revenue projection inherits that weakness and the study acknowledges it. There are no orphan numbers in our pro formas. The complete SBA loan DSCR methodology reference explains the numerator, denominator, current thresholds, global coverage and stress tests in detail.
