The formula divides total annual cost by average borrowed amount. For example, a $100,000 line at Prime + 2.5% with $500 annual fee and 60% utilization yields an effective APR higher than the nominal rate."

Term loans are better for one-time purchases with fixed repayment needs. LOCs offer revolving access and interest-only payments during draw periods, while term loans provide fixed rates and predictable payments."

At 25% utilization on a $100,000 line at 10% rate, you pay $2,500/year in interest. At 75% utilization, interest rises to $7,500/year but you maximize the value of available credit. Some lenders offer rate discounts for lower utilization."

          "text": "Most business lines of credit have variable rates tied to the Wall Street Journal Prime rate. When the Federal Reserve raises rates, your LOC rate increases immediately by the same amount. A 2% Prime rate increase on a $60,000 balance at Prime + 2% adds $1,200/year in interest costs. Consider stress-testing your budget for potential rate increases before drawing heavily."
