Understanding credit cards

Using a credit card for large purchases can be helpful in some situations, particularly if you can make repayments on time, and, where available, take advantage of any introductory or promotional offers. However, it’s important to weigh up the potential benefits against the risks before deciding if it’s the right option for you.

What’s considered a ‘large purchase’ will depend on your financial situation and usual spending rate. For many of us, it could be buying a car, a pre-planned family holiday, or larger household purchases.

But before you commit to making a big purchase using a credit card, it’s wise to shortlist purchase methods that come with a low-interest or 0% APR promotion – be it a loan or credit card and considering factors such as interest rates, fees, and how manageable the repayments will be over time.

In this guide, we’ll walk you through the pros and cons of using credit for large purchases. We’ll also explain how Aqua credit cards work and why it could be the right option for you.

The benefits of paying for a large purchase with a credit card

Making a large purchase using a credit card can be appropriate in some situations provided you borrow within your means and are confident you can make repayments on time.

In some cases, using a credit card may help you benefit from spreading the cost of significant purchases over a longer and more manageable timespan. If managed responsibly, it may also contribute to building your credit history over time.

Having more financial flexibility also means you can consider options that might otherwise be unaffordable as a one-off payment. Be it home renovations, a new appliance, or a family trip abroad. While this added flexibility can be useful, it’s important to avoid relying on credit for purchases that may be difficult to afford, even when spread over multiple payments.

Unlike other payment options, purchases made using a credit card often come with other benefits such as fraud protection, extended warranty, or even points – with each perk often enhanced for high-value purchases.

Depending on your credit card provider, you can also take advantage of payment reminders and other in-app money-management tools to help you stay on track. All of which are available in the Aqua app.

The potential risks of paying with a credit card

Before you start spending, it’s important to understand how credit card payments work and the potential drawbacks attached to making large purchases using a credit card.

One of the prominent risks is the false sense of available funds and potential for overspending, which can quickly escalate into unmanageable debt negatively impacting your credit score.

Other risks include carrying a substantial balance accruing interest, meaning you pay more for purchases in the long run. For that reason, it’s important to clear your balance as soon as financially possible.

You should also be mindful of credit utilisation and how it can harm your credit health. If you continually carry a balance close to your credit limit, lenders might infer you’re dependent on credit and a higher risk for future financial products, such as a mortgage.

If you’re considering making a large purchase on your credit card, be realistic about what you can afford to repay each month. If there’s any doubt you’ll struggle to pay off your balance, it might be best to postpone a large purchase.

How large purchases affect your credit score

Making a big purchase using your credit card can have a significant impact on your credit score, both positive and negative. For that reason, it’s wise to know how credit cards work before you commit to a significant amount of spending.

Whenever you make a purchase using a credit card, your credit utilisation increases. Beyond the financial flexibility, carrying a balance close to your credit limit can lower your credit score, making it harder to secure other financial products.

But should you make a big purchase using your credit card and pay down your balance before a statement deadline, the long-term impact could help improve your score and demonstrate to lenders you’re financially responsible.
