CONFIDENTIAL • VERIFIED 2026 STANDARDS

2026 Institutional Underwriting Formula Pack

The master quantitative reference guide for commercial real estate, clean energy yield modeling, industrial cap rates, and corporate debt sizing.

🏢 1. Commercial Real Estate & Capitalization Rates

Used by REITs, private equity funds, and commercial appraisers to value cash-flowing commercial real estate assets.

NOI = Gross Potential Rent - Vacancy Loss - Operating Expenses (Opex)
Asset Valuation = NOI / Exit Capitalization Rate
Going-In Cap Rate = (Year 1 NOI / Total Acquisition & Capex) × 100

Key 2026 Benchmark: Industrial Cleanrooms trade at 4.70%–5.25% exit caps; self-storage at 5.50%–6.20%.

🏦 2. Debt Service Coverage Ratio (DSCR) & Loan Sizing

Calculates the buffer of cash flow available to service principal and interest debt payments.

Annual Debt Service = [Loan × r(1 + r)^n] / [(1 + r)^n - 1]
DSCR = Net Operating Income (NOI) / Annual Debt Service
Max Loan Supported = NOI / (Target DSCR × Annual Loan Constant)

Key 2026 Benchmark: Institutional commercial lenders require a minimum 1.25x to 1.35x DSCR.

⚡ 3. Levelized Cost of Storage (LCOS) & Energy Arbitrage

Measures the net discounted lifetime cost per MWh delivered by utility-scale battery or sCO2 systems.

LCOS ($/MWh) = (Total Lifetime Capex + Opex + Charging Cost) / Total Lifetime MWh Discharged
Daily Net Margin = (Peak Discharge $/MWh × Discharged MWh) - [(Discharged MWh / RTE) × Off-Peak $/MWh]

Key 2026 Benchmark: 8-hour Flow Batteries (VRFB/Iron-Flow) achieve 70%–75% Round-Trip Efficiency (RTE).

💻 4. SaaS Capital Velocity (CAC Payback & LTV:CAC)

Evaluates growth sustainability and marketing capital efficiency across enterprise cohorts.

CAC Payback (Months) = CAC / (Monthly ARPU × Gross Margin %)
Customer Lifetime Value (LTV) = (Monthly ARPU × Gross Margin %) / Monthly Logo Churn %
LTV:CAC Ratio = LTV / Customer Acquisition Cost (CAC)

Key 2026 Benchmark: Top-quartile enterprise SaaS targets < 12 months CAC payback and > 4.0x LTV:CAC.

🚢 5. Maritime Dual-Fuel Vessel Distributable Cash Flow

Underwrites long-term bareboat and time-charter equity dividend yield on Newcastlemax / LNG carriers.

Annual Distributable Cash = (TCE Rate/Day × 358 Days) - (Opex/Day × 365 Days) - Annual Debt Service
Cash-on-Cash Dividend Yield = (Annual Distributable Cash / Equity Invested) × 100
