Overview

Managing cash flow means matching the timing of cash inflows and outflows. Working capital lines and term loans are two common business credit tools, but they affect cash flow very differently. This guide explains how each product works, shows simple math to compare costs, outlines practical use cases, and gives a checklist to help you choose the right option for your business.

Sources cited in-line: U.S. Small Business Administration (SBA) on loan programs and maturities (https://www.sba.gov), and consumer-focused guidance from the Consumer Financial Protection Bureau (https://www.consumerfinance.gov). For practical definitions and examples I also reference industry-standard explanations (Investopedia) when helpful.

Professional note: In my experience advising small and mid-sized businesses, mixing a modest revolving line with a term loan for major purchases often provides the best cash-flow flexibility while keeping financing cost predictable.

How the two products change cash-flow timing

  • Working capital line of credit (revolving): Think of this as a business charge card or overdraft with a set credit limit you can draw, repay, and draw again. Interest accrues only on outstanding balances. Many lenders offer interest-only payment periods or minimum interest payments while the line is open. Because you repay principal when cash is available, monthly cash outflows can be small and variable.

  • Term loan: You receive one lump sum and repay principal plus interest on a regular schedule (monthly, quarterly, etc.) over a fixed term. Payments are usually consistent (amortizing) unless the loan includes a balloon payment or interest-only period. This predictability helps budgeting but creates a fixed required outflow that must be covered regardless of short-term revenue dips.

Short example: Monthly cash-flow impact and total interest

Scenario A — Term loan

  • Loan amount: $100,000
  • Interest rate: 8% APR
  • Term: 5 years (60 months)

Monthly payment (fully amortizing) = about $2,028. Total paid over 60 months ≈ $121,680; total interest ≈ $21,680.

Scenario B — Interest-only draw on a working capital line

  • Outstanding balance: $100,000
  • Interest rate: 8% APR
  • Interest-only monthly cost = $100,000 × 0.08 / 12 = $667.

Comparison

  • Near term: the line gives lower monthly cash outflow ($667 vs $2,028), freeing ~ $1,361 for operations.
  • Long term: if you keep paying interest-only and delay principal repayment, you’ll eventually have to pay the $100,000 principal or refinance it, which increases total interest and refinancing risk.

This illustrates the core trade-off: lines improve short‑term liquidity but can raise total financing cost and refinancing risk if principal isn’t reduced on a disciplined timeline.

When to use a working capital line

  • Seasonal revenue swings (retail holiday inventory, landscaping in spring/summer).
  • Smoothing payroll, supplier timing gaps, or covering temporary DSO spikes.
  • Opportunistic buying (bulk discounts) where you expect quick payback.
  • As a liquidity backstop to avoid tapping emergency/high-cost lenders.

Operational tips

  • Keep utilization at sustainable levels; lenders often look at utilization when renewing credit and pricing. High, persistent utilization can trigger covenant changes or higher rates.
  • Track days sales outstanding (DSO) and burn rate to know when to draw and when to repay.

When to use a term loan

  • To buy fixed assets (equipment, vehicles), fund a leasehold improvement, or refinance higher-cost debt.
  • When you want predictable payments to fit a budget or investor expectations.
  • When the project generates steady, long-term cash flows that service principal and interest.

Operational tips

  • Match the loan term to the useful life of the asset when possible (matching principle). Longer maturities lower monthly payments but increase total interest.
  • Consider fixed vs. variable rates. Fixed rates reduce interest-rate risk; variable rates may be cheaper initially but expose cash flow to rate hikes.

Cash-flow management strategies

  1. Hybrid approach: Maintain a modest, committed line of credit for seasonality and emergencies, and use term loans for planned capital expenditures. This preserves liquidity while keeping long-term leverage predictable.
  2. Ladder maturities: Stagger term loans so you don’t face large principal repayments all at once.
  3. Build covenants into decision-making: Know coverage ratios lenders require (DSCR, fixed-charge coverage) and model the impact of a 20–30% revenue decline.
  4. Use waterfall modeling: Prioritize operating expenses, debt service, and then discretionary investment. Stress-test for slow sales months.

Common underwriting factors that affect cash flow outcomes

Lenders evaluate items that also determine how a loan will affect your cash flow:

  • Revenue consistency and concentration
  • Cash reserves and existing debt service
  • Collateral availability (accounts receivable, equipment, real estate)
  • Owner personal guarantees and credit scores

SBA-backed loans, for example, have guidelines and maturities tailored to loan purpose; the SBA site explains program differences and typical maturities (https://www.sba.gov/funding-programs/loans).

Red flags and pitfalls to avoid

  • Treating a line as “free money.” Interest—even during short-term use—adds up. Plan principal paydown or refinance.
  • Excessive reliance on short-term, high-cost lines that must be rolled over; this creates refinancing and rollover risk.
  • Mismatching: using a line for a long-lived asset (e.g., a $200k machine) rather than a term loan can raise total cost and add unpredictability.

Decision checklist: Which should you choose?

  • Purpose: Is this for routine timing gaps (line) or a one-time asset (term)?
  • Cash-flow stability: Do you have reliable cash inflows to cover fixed term-loan payments? If not, a line provides breathing room.
  • Cost vs. certainty: Do you prefer lower short-term payments (line) or lower long-term cost and certainty (term)?
  • Term and amortization match: Does the loan term match the economic life of the expense or asset?
  • Covenants and flexibility: Will lenders require covenants that limit operations or distributions?

If more than two answers favor certainty and long-term planning, prioritize a term loan. If your primary problem is timing and variability, prioritize a line.

KPIs to watch after borrowing

  • Debt Service Coverage Ratio (DSCR): Net operating income divided by total debt service. Aim for >1.25 for cushion.
  • Current Ratio (current assets / current liabilities): a quick liquidity measure.
  • Days Sales Outstanding (DSO): Faster collections reduce line usage.
  • Line utilization (% of available credit in use): Keep this moderate to preserve renewal options.

Practical next steps

  1. Run a three-way forecast (income statement, balance sheet, cash flow) for 12–24 months under base, downside, and upside cases.
  2. Price out both products with at least two lenders; include fees, covenants, prepayment penalties, and renewal terms for lines.
  3. If you take a line, set an internal repayment discipline (e.g., pay down to 20% utilization after peak season).
  4. Review SBA and consumer protection guidance: SBA loan programs and comparatives (https://www.sba.gov/funding-programs/loans); for borrower protections and transparent pricing, see Consumer Financial Protection Bureau resources (https://www.consumerfinance.gov).
