Key differences

Lines of credit come in four main flavors. Understanding the trade-offs between cost, speed, and eligibility saves you time and money.

Type	APR Range (2026)	Best For	Speed	Typical Limit
Unsecured personal	8–18%	Individuals; flexible spending	5–10 days	$1,000–$50,000
Unsecured business	10–22%	Small businesses; no collateral	7–14 days	$5,000–$250,000
Secured (asset-backed)	6–14%	Owners with equipment, inventory, or real estate	10–20 days	$10,000–$500,000+
SBA-backed	8–11% APR	Established businesses (24+ months); max credit strength	30–45 days	Up to $5,000,000

Why rates differ: Unsecured lines carry higher rates because the lender has no collateral to recover if you default. Secured lines use your assets as insurance, so rates drop. SBA-backed lines hit the sweet spot—a government guarantee (75–80% of the loan amount) lets banks offer competitive rates despite the risk profile.

For businesses in Charleston operating seasonal industries—hospitality, construction, retail—a line of credit beats a term loan because you draw only what you need when you need it. Say your restaurant needs $40,000 to cover payroll in a slow month; you draw that amount, pay interest on $40,000, and repay it when cash improves. With a term loan, you'd receive $40,000 upfront and owe installments whether business is brisk or dead.

The eligibility threshold most people miss: You need at least 24 months in business for SBA backing and a debt-service coverage ratio (DSCR) of 1.25x or better—meaning your business income must cover 125% of the line payment. A $50,000 line at 10% over five years costs roughly $943/month; your business must show ~$1,179/month in excess cash flow after all other debt payments. Personal lines have looser DSCR rules but look harder at personal credit score and income.

Credit utilization matters more on unsecured lines. Lenders track how much of your available credit you're using. Staying under 30% of your limit protects your credit score and signals responsible management to future lenders. Maxing out a $100,000 line signals financial stress and tanks your score by 50+ points.

In Charleston, whether you're a restaurant startup needing equipment financing or an urgent care operator planning expansion, a line of credit lets you invest in growth without committing to a fixed payment if revenue stalls. Choose based on your credit strength, collateral available, and timeline. Get pre-qualified with a soft pull—no credit-score hit—to see what rate you actually qualify for in under 5 minutes.
