Contactless spending is designed to make everyday life run smoothly, yet it can also make your budget feel harder to pin down. A week of small taps can add up before you even notice, especially when transactions don’t appear in your account right away.
However, you don’t need to change the way you pay to manage your money better. One example of a way to budget is known as the 50/30/20 rule.
What is the 50/30/20 rule?
The 50/30/20 rule is a way of dividing up your spending based on percentages of your regular income:
- 50: Set aside around half of your income for essential costs such as rent, utility bills, travel, mobile data, food and other non-negotiables.
- 30: Allocate up to 30% for things you enjoy, from occasional meals out to small home comforts or entertainment.
- 20: The final 20% goes towards strengthening your long-term position, whether that means growing savings, building an emergency fund, or reducing existing debt.
You may find it useful to divide up your expenses differently, but this is a good example of how you can get a clearer idea of what you can commit to each month. It can help you to avoid overspending and manage any surprise expenses that may crop up.
Where credit cards fit in (and what to watch out for)
Credit cards can work well within a strict budget, but only when you treat your spending as though the money leaves your account straight away. Unlike debit card payments there is a delay when paying by credit card between buying something and then paying for it. This gap can make it seem as though you have more budget available than you really do.
If you don’t track purchases as you go, you can easily start dipping into money that you’ve already earmarked for other needs or savings. It can also be tempting to see your available credit and stretch your spending, even when your income hasn’t changed.
You reduce these risks when you log each purchase soon after making it. This process helps you to stick to a budget and prevents next month’s statement from catching you off guard.
Tools to keep spending visible and honest
To keep your budget accurate, record any card purchases as soon as you make them. Inputting your outgoings means you know what you’ve spent your money on and the payment method you used. You might want to do this using a spreadsheet or simply take out a pen and paper so you have a physical representation of your accounts.
It’s also worth using apps to help. There are apps that are designed to allow you to fully document where you are when it comes to spending.
Setting reminders to check your credit card account can also be beneficial. Getting into the habit of looking at your credit card statement means you can see exactly when the money is deducted from your card. Some credit card accounts also highlight patterns in your spending, giving you a chance to spot shifts early.
A lot of budgeting and banking apps apply real-time updates and tag your purchases automatically, helping you understand whether each transaction counts as a need, a want or part of your long-term plans. If you like everything in one place, some apps and tools can link to multiple accounts and give you a broader overview.
Keep the debt in check or your budget won’t work
Sticking to a budget means you need to clear your credit card balance regularly. When interest starts to be added to your balance the purchases you’d made effectively start to cost more and can start to eat into your savings.
Paying your statement in full each month, if you can afford it, means your budget reflects the real cost of your spending. It’s also a good behaviour that could, over time, have a positive impact on your credit score, as it shows you’re managing your card responsibly. Just remember that not using your card responsibly, like missing multiple payments, could damage your score.
If the balance starts to rise, adjust your “wants” spending until you’re back on track. This keeps your finances steady and helps you stay confident with your choices – even when most spending tends to happen with a quick tap.
