This is generally the interest rate that you see on the bank’s website and loan advertisements.
It only takes into consideration the loan amount and nothing else.
For example, if the flat, applied, nominal or advertised interest rate is 10%, you have to pay $100 interest for a $1,000 loan.
- What is Effective Interest Rate (EIR)?
This is the actual interest rate that you are liable. That’s why it’s also known as the true cost of a loan.
