# What Is a Bank Interest Rate?

An interest rate is a percentage of an amount that is due over a period of time. This rate is a function of the principal sum, the frequency of compounding and the length of time over which the money is held. A bank’s interest rate is usually a little higher than its rivals’, but it is still important to understand. Here is a simplified example of the bank interest rate. Its basic formula is the same as that used by most other banks. 아파트담보대출

## Simple example of bank interest rate

Bank interest rates vary depending on the type of loan and the amount of money you borrow. The most common type is the fixed interest rate. This type of interest rate is fixed throughout the life of the loan, and is often agreed to by both parties. Often, the fixed rate is more convenient to calculate and provides a clear idea of your obligation to the lender. Here’s a simple example of how banks set interest rates.

## Net interest rate spread

A bank’s net interest rate spread measures its income from depositors. This is similar to the profit margin for a business, as the wider the spread, the more profit the bank earns. This measure can fluctuate, however, so it’s important for a bank to keep track of it. This can increase or decrease as interest rates fluctuate. Banks must carefully monitor this ratio in order to make sure they’re earning more than they’re spending.

## Real interest rate

When a bank charges you interest, the actual amount you earn will vary. A real interest rate takes the effect of inflation into account, which will lower the amount you actually earn on your money. Inflation affects both the cost of savings and the value of savings accounts, so the real interest rate is an important concept to grasp. Inflation increases prices, so when this happens, the purchasing power of your money decreases. Conversely, when inflation falls, your savings will increase in value.

## Changes in interest rates

Bank interest rates affect the decisions of households and businesses. When deposit interest rates increase, households save more money while businesses invest less, which leads to higher loan payments and lower demand. Consumer spending decreases as rates increase, leading to higher inflation. Increasing rates result in higher loan payments and lower consumer demand. As a result, bank interest rates affect the economy and financial markets. Therefore, a low rate is positive for the economy.
