Interest is usually given as a percentage per year.

How Do Banks Decide How Much Interest To Charge?

Banks borrow from the Federal Reserve and then lend that money to you, for a higher price.

The Fed can either raise rates to fight inflation or lower them to boost the economy.

Secured vs.

Unsecured Loans

Different loans carry different levels of risk and administrative costs for the bank.

This higher risk for the bank means that these types of loans often come with higher interest rates.

Fixed vs.

Variable Interest Rates

A fixed interest rate remains the same throughout the life of the loan or investment.

A variable interest rate can change over time based on market conditions and the Federal Reserves rates.

While variable rates may start lower than fixed rates, they could increase significantly, leading to higher payments.

Common fees include overdraft fees, service fees, late-payment fees and ATM fees.
