There is no one-size-fits-all best rewards credit card. It's best you research what type of rewards program you'd like, as well as the fees, interest rate and conditions associated with those types of cards before making a choice. 

Rewards credit cards can also come with high annual fees that may end up nullifying the rewards, so think how often you use the card to decide whether the benefits outweigh the extra cost for you. A card with a lower annual fee might require a lot of spending to get any useful rewards, while another card with a higher annual fee might need fewer purchases to get a reward. 

Your credit card will be charged interest when you don’t pay off the balance on your credit card. Your card provider or bank charges you the individual interest rate that is associated with your card, which is usually between 10 and 20 per cent. 

The interest will be added onto your bill each month or billing period if you don’t pay off the balance, unless you are in an interest-free period.

You will be charged interest on anything that hasn’t been paid for inside the interest-free period. Usually you will receive a notice on your bill or statement saying you will be charged interest so you have some form of notice before you’re charged.

The credit card market changes all the time, so the credit card with the highest annual percentage rate is also liable to change.

Keep in mind that credit card interest rates are expressed as a yearly rate, or annual percentage rate (APR). A low APR is generally good but also consider:

• There can be different APR's for each feature of the card (e.g. purchases may have an APR of 14 per cent, while cash advances on same card could have an APR of 17 per cent.
• Credit cards with a variable rate can change throughout the year, affecting your APR, so check the full details.
• If you pay your balance in full every month, having the lowest APR is not as important as the other fees associated with the card. However, if you carry a balance from month to month, then you want the lowest APR possible.

Generally, when we talk about credit card interest, we mean the purchase interest rate, which is the interest charged on purchases you make with your credit card.

If you don’t pay your full balance each month (or even if you pay the minimum amount), you are charged interest on all the outstanding transactions and the remaining balance. However, interest is also charged on cash advances, balance transfers, special rate offers and, in some cases, even the fees charged by the company.

The interest rate can vary, depending on the credit card. Some have an interest-free period, otherwise you start paying interest from the day you make a purchase or from the day your monthly statement is issued. So avoid interest by paying the full amount promptly.

Paying or transferring debt from one lender to the other is called a balance transfer. This involves transferring part or all of the debt from a credit card with one lender to a credit card with another. As part of the process, your new lender will pay out the old lender, so that you now owe the same amount of money but to a new institution.

Many credit card providers offer an interest-free period on balance transfers to help new applicants better handle their debt. During this period, cardholders are not required to pay interest on the debt they brought over from the other card. This can be a great opportunity for consumers to pay off credit card debt with no interest. There are often fees associated with balance transfers; normally, these are a percentage of the amount transferred.

So make sure you read the terms and conditions of the card before transferring any debt across.

Credit card interest can quickly turn a manageable balance into unmovable debt. So being able to understand how interest rates translate into dollars is an important skill to acquire.

The common mistake people make is focusing on the credit card’s annual percentage rate (APR), which often sits between 15 and 20 per cent. While the APR does provide a rough idea of how much interest you’ll pay, it’s not entirely accurate.

This is because you actually accrue interest on your balance daily, not annually. So, you need to work out your daily periodic rate (DPR). To do this, divide your card’s APR by the number of days in a year (e.g. 16.9 per cent divided by 365, or 0.05 per cent). You can then apply this figure to the daily balance on your credit card.

It is possible to get a credit card as a pensioner. There are some factors to keep in mind, including:

• Annual income. Look for credit cards with minimum annual income requirements you can meet. 
• Annual fees. If high fees are a concern for you, opt for a card with a low or $0 annual fee. 
• Interest rate. Make sure you won’t have any nasty surprises on your credit card bill. Compare cards with a low interest rates to minimise risk.

You can apply for a credit card online, over the phone or in person at the bank. Once you’ve compared the current credit card offers, the application process is quick and easy. Before you get your application started, you’ll need to gather your personal information like proof of ID, payslips and bank statements, proof of employment and details of your income, assets and liabilities. To be eligible for a credit card, you’ll need to be an Australian citizen over 18 and earn a minimum of $15,000 each year. Once you’ve applied for a credit card, you should get a response fairly instantly. If your credit card application has been approved, you should receive a welcome pack with your new credit card within 10-15 days.

It’s important to cancel your old cards to avoid any additional fees. Unless you’re doing a balance transfer, you’ll need to pay the outstanding balance before you cancel your credit card. If you’ve opted for a card with reward points, make sure you redeem or transfer the points before you close your account. To avoid any bounced payments and save yourself an admin headache, redirect all your direct debits to a new card or account. Once you’ve done all the preparation, call your bank or credit card provider to get the cancellation underway. Once you receive a confirmation letter, destroy your card and make sure the numbers aren’t legible.

There's no such thing as a free lunch. All credit cards come with associated costs when used to make purchases, even if it’s simply the cost of making repayments.

However, many lenders offer incentives for customers such as a $0 annual fee or 0 per cent interest on purchases during an introductory period. Additionally, paying off your balance in full during an interest-free period means you could only have to pay back the cost of purchases without interest. You could also be eligible for additional rewards such as cashback during that time, saving you more money.

Credit cards are a quick and convenient way to pay for items in store, online or over the phone. You can use a credit card as a cashless way to pay for goods or services, both locally and overseas. You can also use a credit card to make a cash advance, which gives you the flexibility to withdraw cash from your credit card account. Because a credit card uses the bank’s funds instead of your own, you will be charged interest on the money you spend – unless you pay off the entire debt within the interest-free period. If you pay the minimum monthly repayment, you will be charged interest. There are many different credit card options on the market, all offering different interest rates and reward options.

Once you've compared credit card interest rates and deals and found the right card for you, the actual process of getting a credit card is quite straightforward. You can apply for a credit card online, over the phone or in person at a bank branch. 

A credit card can be an easy way to make purchases online, in person or over the phone. When used properly, a credit card can even help you manage your cash flow. But before applying for a credit card, it’s good to know how they work. A credit card is essentially a personal line of credit which lets you buy things and pay for them later. As a card holder, you’ll be given a credit limit and (potentially) charged interest on the money the bank lends you. At the end of each billing period, the bank will send you a statement which shows your outstanding balance and the minimum amount you need to pay back. If you don’t pay back the full balance amount, the bank will begin charging you interest.

A credit card can be a useful financial tool, provided you understand the risks and can meet repayment obligations.

If you’re a credit card first-timer, review your options. Think about what kind of credit card would suit your lifestyle, and compare providers by fees, perks and repayments.

Once you’ve selected a card, it’s time to apply. Credit card applications can generally be completed in store, online or over the phone.

When you apply for a credit card for the first time, you must meet age, residency and income requirements. As proof, you must also provide documentation such as bank account statements.

There are a few ways to pay a credit card bill. These include:

• BPAY - allows you to safely make credit card payments online.
• Direct debits - set up an automatic payment from your bank account to pay your credit card bill each month. You can choose how much you want to pay of your credit card bill when you set up the auto payments.
• In a branch.
• Via your credit card provider's app.

You can get money from a credit card, but generally it will cost you.

Withdrawing money from a credit card is called a cash advance, as it operates more as a loan than a simple cash withdrawal. Because it is a loan, you may be charged interest on your cash advance as soon as you make the withdrawal. Interest rates are also usually much higher for cash advances than standard credit card purchases.

In addition to the interest rate, you may also be charged a cash advance fee. This could be a flat rate, or a percentage of your total cash advance. If you are considering a cash advance, make sure to add up how much it will cost you before committing.

Losing your credit card is a serious situation, and could land you in financial trouble. Here is a simple guide detailing what to do when you lose your credit card.

Lock you card – Contact your provider and inform them about your lost credit card. From here lock, block or cancel your card.

Keep track of transactions – Look out for unauthorised credit card transactions. Most banks protect against fraudulent transactions.

Address recurring charges – If your card is linked to recurring charges (gym membership, rent, utilities), contact those businesses.

Check credit rate – To ensure you’re not the victim of identity theft, check your credit rating a month or two after you lose your credit card.

Looking to get your first credit card? You might be confused as to exactly where to go to apply for one. Here’s where to go when you are ready to put in that application.

The bank: Your bank is a great place to start, provided that you have a good banking history. Since you already have a financial history, you have more chance of your application being approved.

Credit card provider: Another option is to apply for a credit card directly from the issuer, such as Visa, Mastercard or Amex. This will most likely be an online application, so do your research and apply for a suitable card for your circumstances.

Major retailers: Coles, Woolworths, Myer and David Jones all have credit cards available. But watch out for the interest rate and annual fees – these cards are designed to help you spend more in store.
