Background

After the 2008 financial crisis, lenders broadened underwriting from credit scores and revenue to deeper cash-flow analysis. Today underwriters want to know not just how much a borrower earns, but when cash arrives, how it’s used, and how resilient those cash flows are to disruption.

How lenders evaluate cash flow (practical checklist)

  • Bank-statement analysis: Lenders review 6–24 months of business and personal bank statements to confirm actual deposits, recurring revenue and large one‑time inflows or outflows. Alternative lenders commonly rely more heavily on bank‑statement underwriting than traditional banks. See our guide on how lenders use bank statements for details: how lenders use bank statements.
  • Tax returns and Schedule C/1120/1065: Tax forms verify reported income but can mask cash timing; underwriters reconcile tax numbers with bank activity (IRS guidance on recordkeeping and returns is a baseline reference (https://www.irs.gov)).
  • Adjusted cash flow / owner discretionary adjustments: Lenders convert accounting profit to cash available for debt by adding back non‑cash items (depreciation), removing one‑time owner perks, and normalizing payroll and related party transactions.
  • Debt Service Coverage Ratio (DSCR): DSCR = Net Operating Income / Total Debt Service. Lenders use DSCR to check whether cash covers principal and interest. Many commercial lenders expect DSCR > 1.1–1.35 depending on loan type; higher for conservative underwriting. See our DSCR primer: Debt Service Coverage Ratio (DSCR) for Small-Business Borrowers.
  • Cash flow forecasts and stress testing: Forward projections (monthly or quarterly) show seasonality and liquidity gaps. Lenders often run stress tests — for example, a 10–30% revenue shock or delayed receivables — to estimate downside risk. For more on projections in underwriting, see: cash flow forecasts in underwriting.
  • Working capital components: Accounts receivable aging, inventory turnover and accounts payable practices tell lenders about cash conversion cycles and concentration risk.
  • Capital expenditures and lease obligations: Expected capex or rising lease payments reduce free cash flow available for debt.
  • Reserves and liquidity buffers: Lenders prefer seeing contingency reserves or committed credit lines to cover shortfalls.

Key metrics lenders use (what they watch closely)

  • Net cash flow (period): actual cash receipts minus cash paid in the same period.
  • Free cash flow to debt service: operating cash minus capex and required distributions.
  • DSCR and interest coverage ratios (monthly or annualized).
  • Cash conversion cycle: days inventory + days receivable − days payable.
  • Owner compensation and discretionary expense adjustments.

Real‑world examples (concise)

  • Seasonal retailer: High annual revenue but negative cash January–March. Lenders asked for 12 months of bank statements, a seasonal cash flow forecast, and a seasonal working capital facility to bridge off‑peak months. Without reliable forecasts, loan offers included higher interest or covenants limiting distributions.
  • Early‑stage startup: Strong revenue projections but negative historical cash flow. The lender required a bridge loan with a shorter term, higher rate, and a monthly reporting covenant until cash flow stabilized.

Who is affected

Both individuals (mortgages, personal loans) and businesses (term loans, lines of credit) face cash‑flow underwriting. Self‑employed borrowers and seasonal businesses encounter more scrutiny because their tax returns and revenue figures often don’t show the timing mismatch lenders care about.

Practical steps to improve how lenders view your cash flow

  1. Keep clean bank records and reconcile monthly. Lenders prefer uninterrupted, well‑documented bank histories.
  2. Produce 12‑month monthly cash flow forecasts with conservative assumptions and scenario tests (10–25% downside). Link forecasts to receivable aging and expected payables.
  3. Normalize financials: document one‑time items, owner draws, and related‑party expenses so underwriters can make fair adjustments.
  4. Improve DSCR by reducing discretionary withdrawals, refinancing high‑cost debt, or extending amortization to lower monthly debt service.
  5. Build or formalize a committed line of credit as a liquidity cushion lenders value.

Common mistakes borrowers make

  • Presenting annual revenue without monthly cash detail.
  • Using accounting profit as a proxy for liquidity (ignoring receivables, inventory, capex).
  • Failing to disclose large, irregular deposits or related‑party transfers that lenders will question.

How lenders differ

  • Banks: Tend to require tax returns, financial statements, and reconciled bank statements; they emphasize conservative DSCRs and covenants.
  • Nonbank lenders/fintech: May underwrite primarily on bank statements and cash flow patterns, approving faster but often at higher cost.
  • SBA and government‑backed loans: Require documented forecasts and stronger documentation; consult SBA guidance for program specifics (https://www.sba.gov).
