The Dangers of High-Interest Lines of Credit

As financial professionals working closely with small and mid-sized businesses, we’ve been seeing an alarming trend lately – the rise of high-interest business lines of credit disguised as flexible, quick-access funding options. These products are being marketed to business owners who need fast capital, but the hidden costs are staggering and often overlooked.

Too Long; Didn’t Read

  • We’re Seeing Nearly 70% APY: Some business lines of credit we’ve seen recently have effective interest rates approaching 70% APY – a dangerously high cost of borrowing.
  • High daily or weekly compounding interest makes it difficult to pay down the principal, often leading to more borrowing and deeper debt.
  • Traditional business loans, business credit cards, invoice factoring, and working capital loans offer more sustainable terms and lower long-term costs.

An Example of Nearly 70% APY

Here is an example that helps put this into perspective:

someone paying with a credit card
  • Max Line Amount: $10,950
  • Term: 12 months
  • Daily Interest Rate: 0.19% ($20.59 per day)
  • Weekly Interest Rate: 1.46% ($159.60 per week)
  • Monthly Interest Rate: 5.83% ($638.39 per month)

On the surface, this might not seem like a big deal, but when you calculate the annualized interest rate (APY), it amounts to nearly 70%. That’s not just high – it’s predatory.

Why High-Interest Lines of Credit Are a Problem

Cash Flow Drain

With $600+ in monthly interest payments alone, that’s cash that could otherwise be used for payroll, inventory, or business growth. For a small business, this level of interest can be the difference between staying afloat and closing down.

Compounding Debt

Because the interest compounds daily, the total owed increases rapidly, even if the business makes regular payments. What starts as a manageable amount quickly balloons into an unmanageable debt load.

Debt Spiral

Many businesses are forced to take on additional debt to keep up with these payments, creating a vicious cycle that’s hard to escape. This often leads to even more borrowing – and more interest – which makes it nearly impossible to pay down the original balance.

What We’re Seeing in the Market

Over the past six months, we’ve noticed an uptick in businesses being offered these high-interest lines of credit, often disguised under terms like “flexible financing” or “working capital solutions.” The appeal is obvious – fast approval, limited credit checks, and immediate cash access.

But the true cost is buried in complex repayment structures and daily compounding rates. Business owners are often shocked when they realize how quickly the debt adds up.

Why Businesses Need to Be Cautious

If you see a daily interest rate listed, that’s a red flag. Any lender quoting interest on a daily or weekly basis instead of annually is likely hiding the true cost of borrowing.

The key is to calculate the annual percentage yield (APY) – not just the stated interest rate. A 0.19% daily rate may sound small, but it compounds quickly, leading to an actual annual cost of nearly 70%.

What We Recommend Instead

We strongly advise business owners to explore more sustainable funding options:

Traditional Business Loans

SBA and bank loans offer fixed rates and predictable payments, often with rates between 6%–12%.

Business Credit Cards

With proper management, business credit cards can provide better terms, especially with low or 0% introductory rates.

Invoice Factoring

If you’re cash-strapped due to unpaid invoices, this can unlock cash without high-interest debt.

Working Capital Loans

Short-term business loans with clear terms and reasonable interest rates are often a better option than high-interest lines of credit.

Final Thoughts

The bottom line is this: 70% APY is dangerous territory. If you’ve been offered a line of credit with interest rates anywhere near this level, walk away. There are better options available – and we’re here to help you find them.
