Prioritizing Expenses
Below, I've detailed four types of expenses in order of priority. You'll want to eliminate those at the very top of the list, while you'll probably decide you can live with those toward the bottom of the list.
Destructive Expenses: These push you toward poverty and away from prosperity. They include personal vices, like drugs and gambling. Credit card interest, most loan interest (except loans to purchase cashflowing assets—see Productive Expenses, below), and excessive bank fees (overdrafts, excessive withdrawals, etc.) are the most common in this category. Because financing on so many purchases is so easily extended by retailers, many of us have accepted these expenses as a regular part of life. But that's a lie. Financing everything with credit destroys your financial future and will keep you broke. You want to rid your life of destructive expenses entirely.
Consumptive or Lifestyle Expenses: These create joy and fulfillment in your life as well as memories, but they don't build income or assets. They're typical consumer expenses like going on vacation, buying new clothes, and your housing payment. It's OK to have consumptive/lifestyle expenses, as long as you manage them. Use cash rather than borrowing for these expenses (exception is a house you can afford to finance), and you'll be reducing some of that 34% of income the average American pays in interest every year.
Protective Expenses: These protect your property, health, and income, but generally don't earn a significant cash return. Protective expenses include your liquid savings, life/health/disability/auto insurance, your AAA membership, etc. They're often overlooked and under-prioritized because most people have the wrong money mindset and cut protective expenses in lieu of cutting destructive or consumptive expenses. When it comes to protective expenses, don't make the error of seeking lowest price instead of best value. When life doesn't go as planned, having protection you need and can count on is critical. This is not the place to cut corners in your budget.
