💡 Expert Insight

Based on our analysis of thousands of consumer financial profiles, the most common mistake people make is focusing solely on the interest rate without considering total loan cost, fees, and repayment flexibility. Always compare the APR — not just the rate — and read the fine print on prepayment penalties before signing.
