Whilst it's easy to get lost in a sea of jargon, investment options, and conflicting advice, financial success doesn’t require a degree in economics or hours spent poring over market trends. In fact, according to Helaine Olen and Harold Pollack in their book The Index Card: Why Personal Finance Doesn't Have to Be Complicated, everything you need to know about managing your money can fit on a single index card.

Yes, you read that right—just ten simple rules are all you need to master your financial life.

In this first blog, of a two-part series, we’ll explore five rules will help most people cut through the noise and provide a clear, straightforward path to financial stability and success.

Rule 1: Spend less than you earn

At the heart of financial security lies this golden rule: spend less than you earn. It’s simple in theory but challenging in practice, especially in a world where consumer culture encourages constant spending (AKA: lifestyle creep!). By living within your means, you create the financial flexibility to save, invest, and plan for the future without the looming threat of debt.

Rule 2: Try to pay off your credit card balance in full every month

Credit card debt is one of the most common financial pitfalls. The interest rates are notoriously high, and carrying a balance from month to month can quickly spiral out of control. Olen and Pollack stress the importance of paying off your credit card balance in full each month. This not only saves you from paying unnecessary interest but also instils discipline in your spending habits.

Rule 3: Save 10-20% of Your Income

Saving regularly is key to building wealth over time. The authors suggest setting aside 20% of your income for savings. This may seem ambitious, but starting with any amount and gradually increasing your savings rate can make a significant difference in your financial future. The earlier you start, the more you benefit from the power of compound interest, allowing your savings to grow exponentially over time.

Rule 4: Maximise contributions to retirement accounts

Retirement may seem far away, but it’s crucial to start planning for it as early as possible. Olen and Pollack recommend using the full allowance for contributions to retirement accounts. These accounts often come with tax advantages, and the sooner you contribute, the more time your investments have to grow. It’s about ensuring that your future self has the financial resources to enjoy life after work.

Rule 5: Create an emergency fund

Life is full of unexpected surprises, and not all of them are pleasant. That’s why having an emergency fund is essential. Aim to save three to six months’ worth of living expenses in a readily accessible account. This fund serves as a financial safety net, protecting you from the need to rely on high-interest debt when unexpected expenses arise.
