Business Loan Sustainability: Beyond Lender Approval
Understanding why cash-flow coverage determines loan safety, not just qualification criteria.
The Reality of Business Debt
Debt Service Coverage Ratio (DSCR)
- DefinitionDSCR measures operating cash flow divided by annual debt service. A ratio of 1.0 means cash flow exactly covers debt payments. Below 1.0 is unsustainable.
- Minimum ThresholdsMost lenders require 1.25 minimum. Conservative businesses target 1.5 or higher to maintain operational flexibility and growth capital.
- Why It MattersDSCR reveals whether debt service leaves enough cash for operations, growth, and unexpected expenses. Low DSCR creates liquidity risk even if revenue is growing.
DSCR is a cash-flow metric, not a profitability metric. A profitable business can still have unsustainable debt if cash flow is insufficient.
Stress Testing Loan Sustainability
- Revenue Decline ScenariosModel how DSCR changes if revenue declines 10-20%. This reveals vulnerability to economic downturns or competitive pressure.
- Expense CreepAccount for rising costs: inflation, wage increases, supply chain disruptions. Even small expense increases can push marginal DSCR into dangerous territory.
- Interest Rate RiskIf your loan has a variable rate, model rate increases. A 2% rate increase can significantly impact debt service and DSCR.
Stress testing reveals worst-case scenarios. If a loan is unsustainable under stress, it poses operational risk even in normal conditions.
Common Mistakes in Loan Planning
Using Gross Revenue Instead of Cash Flow
- The ProblemRevenue and cash flow are different. Revenue includes accounts receivable that may not be collected for months. Cash flow reflects actual money available for debt service.
- The SolutionUse net operating cash flow (revenue minus operating expenses) for DSCR calculations. This reflects the actual cash available to service debt.
Lenders may use EBITDA or other metrics, but for your planning, use actual cash flow.
Ignoring Seasonality and Volatility
- Seasonal BusinessesA loan that looks safe using peak-season revenue may become unsustainable during low seasons. Use average monthly revenue over a full year.
- Revenue VolatilityBusinesses with volatile revenue need higher DSCR buffers. A 1.25 DSCR may be acceptable for stable businesses but risky for volatile ones.
Account for your business's specific revenue patterns when evaluating loan safety.
