Whether you're shopping for a home loan or picking out a new credit card, you should know that the advertised APR represents more than the interest rate you're charged. Where your interest rate is represented as a percentage and describes how much interest you'll pay over time, the APR also includes fees and other charges.

What does this mean when it comes to comparing interest rate vs. APR? Generally speaking, this means the APR is typically higher than the interest rate you'll have to pay (but not always). Read on to learn about these two terms and everything that sets them apart.

## Key Takeaways

- While the terms "interest rate" and "APR" are often used interchangeably, these are not exactly the same.
- You can compare loans based on their interest rate or APR, but make sure you're comparing them with the same one across all lenders.
- Ultimately, your interest rate and APR will determine how much money you'll pay when you borrow.

## Interest Rate vs APR: What’s the Difference?

Any time you borrow money, you will want to compare lenders based on the interest rates they charge. Interest rates are expressed as a percentage as we already mentioned, which you will quickly discover when you compare financial products. As an example, the __Board of Governors of the Federal Reserve System__ says that, as of February 2023, the average interest rate on a 24-month personal loan came in at 11.48%

Meanwhile, an APR takes the interest rate for a loan and adds in any fees that are charged. With a credit card, this means the APR includes the interest rate and other fees that can be charged like an annual fee.

### Example of Interest Rate vs. APR

The best interest rate vs. APR example usually comes from mortgages since this type of loan has plenty of added fees that need to be paid. For example, mortgages require borrowers to pay interest on their loan, but borrowers may also pay points on their mortgage, closing costs, mortgage insurance premiums and more.

With some mortgage lenders, for example, you can qualify for a 15-year, fixed rate home loan with an interest rate of 5.50% and an APR of 5.658%.

## What Is Interest Rate?

An interest rate is a numerical figure that describes how much interest you'll pay when you borrow money, expressed as a percentage.

**Interest rates vary**. Interest rates can be higher or lower for various financial products. For example, mortgages and personal loans tend to come with much lower interest rates than credit cards.**Interest rates can be fixed or variable**. Some financial products come with fixed interest rates that stay the same for the duration of the loan term, whereas other financial products have variable rates that fluctuate based on market conditions.**The interest rate you're assigned can depend on your creditworthiness, your income, and other factors.**Generally speaking, you'll qualify for the lowest interest rates when you have a__good credit score__or an excellent credit score.

## How Are Interest Rates Calculated?

Lenders calculate interest rates using a few different methods — simple interest and amortizing interest.

### Simple Interest

With simple interest, you make the same monthly payment each month but the interest charged is based on the original loan balance and the remaining loan balance as your debt is paid down. This means the amount of interest you pay each month goes down as your loan balance decreases.

**Simple interest example**: To determine simple interest on a loan, you'll use the following calculation:

Loan amount x interest rate x loan term = interest

This means that, with a $10,000 personal loan with a 5% rate and five-year repayment term, the formula would be as follows:

$10,000 x .05 x 5 = $2,500

### Amortizing Interest

With an amortizing interest loan, however, more interest is charged toward the beginning of the loan until a good part of the balance has been paid off. At that point, the tables turn and the amount of interest being paid off begins to drop. Toward the end of a loan with amortizing interest, hardly any interest is charged.

**Amortizing interest example**: The formula for an amortizing interest loan is considerably more complicated, and you'll probably need a loan calculator to figure it out.

Either way, imagine you take out a $10,000 loan at 5% with a ten-year repayment term. In this case, the schedule below shows how interest is higher toward the beginning then lower toward the end of the loan term.

Loan Year | Total Principal Paid | Total Interest Paid | Remaining Balance |

2023 | $723.33 | $443.39 | $9,276.67 |

2024 | $1,551.08 | $888.42 | $8,448.92 |

2025 | $2,421.18 | $1,291.11 | $7,578.82 |

2026 | $3,335.80 | $1,649.28 | $6,664.20 |

2027 | $4,297.21 | $1,960.66 | $5,702.79 |

2028 | $5,307.81 | $2,222.84 | $4,692.19 |

2029 | $6,370.11 | $2,433.33 | $3,629.89 |

2030 | $7,486.76 | $2,589.46 | $2,513.24 |

2031 | $8,660.54 | $2,688.47 | $1,339.46 |

2032 | $9,894.37 | $2,727.42 | $105.63 |

2033 | $10,000.00 | $2,727.86 | $0.00 |

## What Is APR?

APR is a term used to describe a financial product's interest rate plus fees that are charged. In other words, APR is meant to portray the total costs of borrowing money.

## How Is APR Calculated?

Because many __credit cards and lines of credit__ don't charge an annual fee or other required fees, it's common for credit cards to have the same interest rate and APR. Other financial products, like personal loans and mortgages, typically have an APR that is higher than the interest rate alone.

To figure out a loan's APR, you'll need to know:

- The loan balance
- Interest rate being charged
- Fees that are charged
- Days in the loan term

Fortunately, you don't have to determine an APR on your own. The __Truth in Lending Act (TILA)__ requires lenders to disclose an APR for each of their financial products.

The Federal Truth in Lending Act requires lenders to disclose all fees and charges that can be included in their loan products. This includes both interest rates and APRs that are inclusive of fees.

### APR Example

To find an example of a loan's interest rate vs. APR, do a quick search for mortgage rates in your area. The screenshot below was taken from the Chase Mortgage website. As you can see, it shows the interest rate for various types of home loans, as well as the APR. The APR is higher since it's inclusive of both the interest rate and mortgage fees that are charged.

In this example, you can easily see that the interest rate on a 30-year, fixed rate mortgage is 5.750% as of publishing, but that the APR for the same loan is 5.840%.

## Why Do Interest Rates and APR matter?

Whether you decide to compare loan offers based on the advertised interest rate or APR, you should know that both are important to consider. The interest rate you're charged will directly impact how much interest you pay when you borrow, and the APR does the same except it also takes loan fees into account.

### Monthly Payment Impact

The interest rate and APR you pay for loans can easily save you (or cost you) tens of thousands of dollars over the course of many years. Let's say you take out a $300,000 fixed-rate home loan with an APR of 5%. In this case, your monthly payment (including principal and interest) comes in at $1,610.46 during that timeline.

Now imagine you get the same mortgage, but with a 7% APR. In that case, your monthly payment goes up to $1,995.91, which means you're paying $385.45 more in monthly interest at the beginning of the loan.

### Impact On Total Borrowing Costs

Considering the example above, you can also see how your total borrowing costs can increase dramatically based on your interest rate and APR.

After all, making a $1,610.46 monthly mortgage payment for 30 years (360 months) means you pay a total of $579,765.60 and $279,765.60 in interest charges over that time.

With the same loan at 7% and a monthly payment of $1,995.91, however, you would pay $718,527.60 in total and $418,527.60 in interest charges.
