Nominal rate vs. APR: the difference that costs you money
The nominal rate is the "pure" interest of the loan, counting nothing else. It's the big, attractive figure in the ads. The APR (Annual Percentage Rate) also includes fees, costs and how often you pay, which is why it reflects the real cost. Two loans with the same nominal rate can have very different APRs if one charges an arrangement fee and the other doesn't.
The practical rule: to compare loans, always look at the APR, never the nominal rate. And be wary of offers that highlight a tiny nominal rate and hide the APR in the small print.
