You may have seen the Annual Percentage Rate (APR) of various loans mentioned in loan advertisements. Seeing those advertisements, you may have often wondered what is APR.
Annual Percentage Rate, or APR, is a percentage of the total cost of your borrowing per year. It takes into account the interest rate and all other charges collected by your lender. It is expressed as a percentage of the principal amount of your loan or credit card.
Loan companies are required to mention APRs in advertisements because APR is a key factor in a borrower’s decision-making process. It’s one of the most important factors considered when choosing a loan or a lender.
In order to pick the most beneficial loan for yourself, you must understand what APR means, how it is calculated, and what a good APR is.

What is APR (Annual Percentage Rate)?
Annual Percentage Rate (APR) is a rate that represents the cost of borrowing money. It is the percentage of interest, processing fees, and all other additional charges paid on a borrowing over the principal amount. It does not take into account the compounding of interest.
The APR stand for “Annual Percentage Rate,” and it provides a standardised way to compare different loan offers. Unlike a simple interest rate, APR includes all costs associated with borrowing, giving you a more complete picture of what you’ll pay.
An APR is a measure to compare various lenders or loan products. You can use it to evaluate options when selecting a lender for your needs. You can find out what is APR on a credit card, a personal loan, or any other line of credit using the mathematical formula of APR.
Annual percentage rate (APR) represents the yearly cost of borrowing money including additional fees, making it more comprehensive than just the interest rate alone.
APR Explained: The Formula For Calculating APR

Understanding how APR is calculated can help you grasp what borrowing money really costs. The formula for calculating APR is:
APR = ((Fees + Interest)/Principal)/n × 365 × 100
Where:
- Interest = Interest paid on loan during the specified period (in £s)
- Fees = Processing fees or any other additional charges on loan
- n = Duration of the loan (in days)
Example 1: APR of a personal loan
Let’s calculate the APR for a loan of £1000 with an interest rate of 15%. Assume that the lender has charged £10 as a processing fee for the loan. The loan term is 180 days.
Based on this data:
- Interest on loan = £1000 × 15% × 180/365 = £74 (rounded off)
- APR = [(74+10)/1000]/180 × 365 × 100 = 17.03%
The APR for the loan is 17.03%. The borrower can compare this rate with the APR offered by other lenders to select the best option.
APR calculations can be complex, so many lenders provide APR calculators on their websites. These tools help you understand the actual cost of borrowing based on your loan amount, term, and other factors.
Is APR the Same as an Interest Rate?
No, APR and interest rate are not the same. Both APR and interest rate are expressed as percentages, but APR is a broader term. Unlike interest rate, APR takes into account the entire cost of borrowing the loan, including additional charges like origination fees. Lenders collect processing fees and other charges to cover their administrative costs.
We can say that an APR gives a better idea of our borrowing costs than a loan’s interest rate because it represents the complete cost of borrowing. As a result, APR is a more useful metric when comparing various loan options.
Here’s a quick comparison of APR and interest rate:
| APR | Interest Rate |
| Includes interest and fees | Interest only |
| Represents total borrowing cost | Represents just the cost of borrowing the principal |
| Required by law to be disclosed | May not include all costs required by law to be disclosed |
| More accurate for comparison | Can be misleading if used alone |
Understanding APR and interest rate differences helps you make better financial decisions when borrowing money.
What is APRC (Annual Percentage Rate of Change)?
APRC is another measure of the total cost of borrowing a loan. It is similar to APR, but it represents the annual cost of a loan over its entire lifetime. Mortgage lenders are required to inform you about the APRC of their products.
APRC is helpful for making decisions about longer-term loans because it’s a more realistic measure of the borrowing cost. APRC considers the total amount of interest paid over a loan’s duration along with legal fees, processing fees, mortgage closing costs, and administrative charges. It assumes the same interest rate initially, but APRC incorporates the changes in the interest rate and fees over time.
For instance, some lenders offer mortgages with introductory offers. A lower interest rate is charged for the first few years and a higher APR is charged for the rest of the term. One cannot judge the loan based on its initial introductory interest rate. However, APRC considers this future interest rate change and provides a realistic measure of borrowing cost.
When comparing mortgages or other long-term loans, looking at both the APR and APRC gives you a more complete picture of your potential costs.
APR on Credit Cards
The method of computing what is APR on a credit card slightly differs from that of a loan. Computing the APR on a credit card can be tricky for credit card providers. If a person does not exceed their credit limit during the year, they may not be charged any interest on the card and their APR would be 0%. Also, credit card providers offer variable APR that changes with market conditions.
However, credit card companies need to quote an APR on credit cards to help the lenders choose a card. They use a standard format to compute the representative APR on credit cards.
The APR on credit cards is computed based on how much it will cost if you borrow an assumed credit limit of £1,200 in a year in a representative example. While computing the rate, it is assumed that the borrower has used their credit limit fully on the first day and it has been paid back in equal and regular instalments throughout the year. It is assumed that while repaying the credit card balance through the year, you incur no further expenses to your credit card.
Credit card’s APR typically includes:
- Interest on purchases (purchase APR)
- Balance transfer fees
- Cash withdrawal fees
- Annual card fees
- Late payment fees
Credit card’s purchase APR is the rate applied to purchases made with your card. If you pay your monthly credit card statement in full by the due date, you typically won’t pay any interest at all.
Representative vs Personal APR
During the process of borrowing money, you may notice that the actual APR on your loan was different from the one advertised by the lender. This happens because the APR that you use to compare loan products is a representative APR. The APR that you actually get is your personal APR.
Before you calculate what is APR on a loan, you must understand the difference between representative and personal rates.
Representative Annual Percentage Rate
The APR that a lender advertises is called the advertised APR or representative APR. It is calculated in a regular manner, after considering interest as well as additional charges. However, not all applicants will receive credit at this advertised rate.
The bank has to give credit at this rate to at least 51% of successful applicants whose applications were accepted. It means that 49% of the applicants may need to pay a higher APR on their loans. In some cases, some lenders might even give you a lower or discounted APR.
Lenders do not select random applicants who must pay more for their loans. Actual APR varies according to the eligibility of the borrower.
Representative APR advertised by lenders helps you compare different loan options, but remember that it’s not guaranteed for everyone. Your personal financial circumstances will determine your actual rate.
Personal Annual Percentage Rate
The rate that the lender actually offers to the borrower is called a personal APR. For at least 51% of the accepted applicants, it will be the same as the representative APR. For others, it will be higher. Lenders decide this rate according to the borrower’s credit score, credit history, and other financial parameters.
Your personal APR depends on:
- Your credit rating
- Your income and employment status
- Your existing debt
- Your relationship with the lender
- The loan amount and term
Lenders must provide your personal APR in your signed credit agreement before you finalise the loan. This gives you a chance to review the actual cost of borrowing before committing.
An indicative personal APR may be provided before a full application, giving you an idea of what rate you might qualify for based on a soft credit check.
Factors That Affect Your Personal APR
1. Type of Credit
Lenders charge different interest rates and additional charges for each type of credit. They might charge higher interest rates for riskier products like unsecured loans or bad credit loans. Naturally, the APR is also different for various loan types.
For example, you cannot compare the APR of a payday loan with the APR of a housing loan. The rate of a payday loan is going to be higher than that of a housing loan because a payday loan is unsecured and considered riskier.
2. Credit Score
A credit score is a measure of your creditworthiness. Your personal APR can change according to your credit score. It can be higher than your representative APR if you have a poor credit score. Again, this is related to the lender’s risk. If you have a low credit score, you are viewed as a riskier customer, and you will be charged a higher interest rate.
Major credit reporting agencies in the UK use your credit history to generate your credit score. If you don’t know what your credit score is, you can check it on the website of any credit reference agency for free once every year.
Improving your credit score will help you secure a loan at a lower APR. A good credit score can save you thousands of pounds in interest over the lifetime of a loan, especially for large borrowing like mortgages.
If you have past credit repayment problems, lenders will view you as higher risk and may charge a higher APR to compensate.
3. Loan Amount and Duration
APR also changes according to the loan amount and loan term. For instance, the interest rate of short-term loans and long-term loans like housing loans will be different. The charges levied on these loans can also differ. This affects the APR on these loans.
Generally:
- Smaller loans often have higher APRs
- Longer loan terms might have lower APRs but cost more in total interest paid
- Secured loans (against property or assets) typically have lower APRs
- The loan balance can affect the rate you’re offered

4. Income
An important criterion that lenders check while deciding your APR is your income level. A lender will mark you as a higher risk customer if your regular income is low. It means that your personal APR is likely to be higher than your representative APR.
Lenders examine:
- Your annual income
- Employment stability
- Debt-to-income ratio
- Other financial commitments
These factors help determine your ability to make monthly payments on time, which affects the APR you’re offered.
What is a Good APR?
Since APR represents the cost of borrowing, the lower the APR the better. However, there is no standard answer to what is a good APR. Whether your APR is good or bad depends on your financial situation. For instance, for a person with a poor credit score, a higher-than-standard annual rate can seem favorable.
Current market conditions, your credit history, and loan terms all affect what’s considered a “good” APR. What’s good for one person might not be good for another based on their credit rating and financial situation.
Different Types of APR
Fixed APR
A fixed APR remains the same throughout the life of the loan. This provides certainty in your monthly payments, as they won’t change due to market fluctuations. Fixed APR loans are popular for mortgages, personal loans, and some credit cards.
Benefits of fixed APR:
- Predictable payments
- Protection from interest rate increases
- Easier budgeting
However, if market rates fall significantly, you won’t benefit without refinancing.
Variable APR
A variable APR can change over time based on an index interest rate plus a margin. These rates typically move with the Bank of England base rate or LIBOR. Variable APR loans or credit cards may start lower than fixed-rate options but carry the risk of increasing over time.
Variable APR features:
- Can increase or decrease based on market conditions
- Often start lower than fixed rates
- May have caps on how much they can increase
- Common with credit cards and some mortgages
Variable APRs require you to be prepared for potential payment increases if rates rise.
Introductory APR
Many credit cards offer an introductory APR, which is a promotional rate (often 0%) for a limited time. After this period ends, the rate increases to the standard variable APR.
Introductory APR offers can be useful for:
- Balance transfers to pay off high-interest debt
- Making large purchases and paying them off during the promotional period
- Avoiding interest while establishing credit
Always note when the introductory period ends and what the regular APR will be afterward.
Purchase APR
Purchase APR applies specifically to purchases made with a credit card. This rate is used to calculate interest if you don’t pay your balance in full by the due date.
Different transactions on the same credit card may have different APRs:
- Purchases have the purchase APR
- Cash withdrawals often have a higher APR
- Balance transfers may have special rates
Understanding these different APR types helps you use credit more strategically and potentially save money on interest.
How Different APR Rates Affect Monthly Payments
To understand how APR impacts your monthly payments, let’s look at an example of a £10,000 personal loan with a 3-year term:
| APR | Monthly Payment | Total Interest Paid | Total Cost |
| 5% | £299.71 | £789.56 | £10,789.56 |
| 10% | £322.67 | £1,616.12 | £11,616.12 |
| 15% | £346.65 | £2,479.40 | £12,479.40 |
| 24% | £390.79 | £4,068.44 | £14,068.44 |
As you can see, a 5% APR means you’d pay about £790 in interest over the life of the loan. With a 24% APR, you’d pay over £4,000 in interest – more than five times as much!
Even a small difference in APR can make a significant impact on your monthly payments and the overall cost of borrowing. This illustrates why comparing APRs is so important when shopping for credit.
Monthly payments are directly affected by the APR, which is why it’s crucial to secure the lowest rate possible for your financial situation.
Final Thoughts
Annual Percentage Rate (APR) is an important criterion that borrowers use to compare loan products and lenders. It represents what cost you will incur for getting the credit you are applying for.

Understanding how does APR work helps you:
- Compare different loan offers fairly
- Budget for loan repayments
- Understand the true cost of borrowing
- Make more informed financial decisions
Always read the terms and conditions carefully, and make sure you understand all aspects of the APR and other loan features before signing any credit agreement.
