AI for Credit Memo Writing: Claude Tools for Commercial Lending (2026)

Credit Memo Writing and AI

A credit memo is the core deliverable of commercial banking credit work. Senior analysts spend 3-6 hours drafting a memo for a mid-market credit — pulling financials, computing ratios, writing the narrative, formatting the structure table, and drafting the recommendation. Claude with ClaudeFinLab does the heavy lifting: financial analysis, ratio computation, narrative drafting, and covenant structure — leaving the analyst to add judgment and relationship context.

Borrower Overview and Business Description

• "Draft the borrower overview section for a credit memo: XYZ Manufacturing LLC, founded 1997, privately held, metal fabrication for automotive OEMs, headquartered in Detroit MI. Revenue $28M, EBITDA $4.2M (15% margin), 185 employees. Key customers: 3 Tier-1 automotive suppliers (42% revenue concentration). Owner is requesting a $12M term loan for equipment acquisition. Write a 3-paragraph borrower overview in commercial banking credit memo style."
• "Write the industry and market risk section: borrower is in skilled nursing facility operations (3 facilities, 380 beds, 85% Medicare/Medicaid mix). Industry risks: reimbursement rate exposure, staffing shortages (RN vacancy rate 18%), regulatory compliance burden (survey risk). Industry tailwinds: aging demographics, supply constraint on new SNF licenses. Write a balanced 2-paragraph industry assessment for a credit memo."

Financial Analysis and Ratio Computation

• "Compute the credit analysis ratios for this borrower. 3-year historical financials: [paste P&L and balance sheet]. Calculate for each year: (1) EBITDA and EBITDA margin; (2) DSCR (use existing debt service + proposed new debt service); (3) total leverage (total debt / EBITDA); (4) fixed charge coverage; (5) current ratio; (6) quick ratio; (7) days sales outstanding; (8) days payable outstanding. Present in a table with 3-year trend and industry benchmark."
• "The borrower shows revenue growth 12% CAGR but EBITDA margin declining 180bps over 3 years (18.2% to 16.4%). Analyze the margin compression: compute gross margin, SG&A as % of revenue, and EBITDA bridge from year 1 to year 3. Identify likely causes (cost inflation, mix shift, investment in headcount). Assess whether the margin trend is a credit concern or a temporary investment cycle."
• "Perform a global cash flow analysis for this guarantor/borrower: personal tax returns show W-2 income $285K, K-1 from S-corp $840K (distributions $600K), rental income $96K, mortgage payments $3,200/month. Compute global DSCR including personal obligations and business debt service. This is a requirement for SBA loans and many community bank policies."

Loan Structure and Pricing

• "Draft the loan structure section for a $12M term loan: 7-year term, 20-year amortization (balloon at year 7), SOFR+250bps (current all-in 7.85%), first lien on equipment and real estate, personal guarantee (full recourse) from majority owner. Compute: monthly payment (P+I), annual debt service, DSCR at current rate and +200bps stress. Format as a term sheet summary table."
• "Price the credit: borrower is B+ internal risk rating (our 8-point scale). Peer bank pricing for comparable credits in our market is SOFR+225-275bps. Our cost of funds is 4.65%. Target net interest margin 3.0%. Required credit risk premium for this risk grade: 150bps. Recommended pricing: ___. Include origination fee discussion (industry standard 0.5-1.0% for this loan size)."

Covenant and Collateral Analysis

• "Draft financial maintenance covenants for this credit: DSCR ≥ 1.20x (tested quarterly on trailing 12-month basis), total leverage ≤ 4.0x, minimum liquidity (unrestricted cash) $500K. Explain the rationale for each covenant level relative to current performance (DSCR 1.41x, leverage 3.2x, cash $820K). Include cure period provisions: 30-day notification, 60-day cure, subject to waiver at lender's discretion."
• "Assess collateral coverage: equipment appraisal $8.5M (orderly liquidation value), accounts receivable $3.2M (80% advance rate = $2.56M eligible), inventory $1.4M (50% advance rate = $0.7M eligible). Total collateral value: $11.76M against $12M loan request = 98% LTV. Assess sufficiency and recommend whether personal guarantee provides adequate credit support for the shortfall."

Risk Assessment and Credit Recommendation

• "Write the risk factors section for this credit memo (5 bullet points, each with mitigant): risks identified — customer concentration (top 3 = 42% revenue), equipment obsolescence risk (proprietary machinery), key man risk (founder-owner 65 years old), supply chain exposure (single-source steel supplier), and working capital seasonality (Q4 demand spike). For each, write the risk in 1 sentence and the mitigant in 1-2 sentences."
• "Write the credit recommendation section: summarize the credit positives (experienced management, strong local market position, consistent DSCR above 1.25x, clean credit history), note the key risks (customer concentration, leverage at close of 3.2x), state the recommendation (Approve with conditions), and list the approval conditions (annual audited financials, quarterly covenant certificate, DSCR covenant, key man life insurance $5M naming bank as beneficiary)."

Where to Start

Connect ClaudeFinLab's accounting MCP server to handle the ratio computation automatically. Paste the borrower's 3-year tax returns or financial statements and ask Claude to compute DSCR, leverage, and fixed charge coverage in your bank's standard format. Then ask it to draft the narrative sections — borrower overview, industry assessment, risk factors — using the financial analysis as context. A first-draft credit memo takes under 30 minutes instead of 3 hours.
