Here we'll take a look at some of the most common financial mistakes that often lead people to major economic hardship. Even if you're already facing financial difficulties, steering clear of these mistakes could be the key to survival.

Mistake No. 1: Excessive/Frivolous Spending

Great fortunes are often lost one dollar at a time. It may not seem like a big deal when you pick up that double-mocha cappuccino, stop for a pack of cigarettes, have dinner out or order that pay-per-view movie, but every little item adds up. Just $25 per week spent on dining out costs you $1,300 per year, which could go toward an extra mortgage payment or a number of extra car payments. If you're enduring financial hardship, avoiding this mistake really matters – after all, if you're only a few dollars away from foreclosure or bankruptcy, every dollar will count more than ever.

Mistake No. 2: Never-Ending Payments

Ask yourself if you really need items that keep you paying every month, year after year. Things like cable television, music services or fancy gym memberships can force you to pay unceasingly but leave you owning nothing. When money is tight, or you just want to save more, creating a leaner lifestyle can go a long way to fattening your savings and cushioning yourself from financial hardship.

Mistake No. 3: Living on Borrowed Money

Using credit cards to buy essentials has become somewhat normal. But even if an ever-increasing number of consumers are willing to pay double-digit interest rates on gasoline, groceries and a host of other items that are gone long before the bill is paid in full, don't be one of them. Credit card interest rates make the price of the charged items a great deal more expensive. Depending on credit also makes it more likely that you'll spend more than you earn.

Mistake No. 4: Buying a New Car

Millions of new cars are sold each year, although few buyers can afford to pay for them in cash. However, the inability to pay cash for a new car means an inability to afford the car. After all, being able to afford the payment is not the same as being able to afford the car. Furthermore, by borrowing money to buy a car, the consumer pays interest on a depreciating asset, which amplifies the difference between the value of the car and the price paid for it. Worse yet, many people trade in their cars every two or three years, and lose money on every trade.

Sometimes a person has no choice but to take out a loan to buy a car, but how much does any consumer really need a large SUV? Such vehicles are expensive to buy, insure and fuel. Unless you tow a boat or trailer, or need an SUV to earn a living, is an eight-cylinder engine worth the extra cost of taking out a large loan?

If you need to buy a car and/or borrow money to do so, consider buying one that uses less gas and costs less to insure and maintain. Cars are expensive, and if you're buying more car than you need, you're burning through money that could have been saved or used to pay off debt.

Mistake No. 5: Spending Too Much on Your House

When it comes to buying a house, bigger is not necessarily better. Unless you have a large family, choosing a 6,000-square-foot home will only mean more expensive taxes, maintenance and utilities. Do you really want to put such a significant, long-term dent in your monthly budget? (For more, see Mortgages: How Much Can You Afford?)

Mistake No. 6: Treating Your Home Equity Like a Piggy Bank

Your home is your castle. Refinancing and taking cash out on it means giving away ownership to someone else. It also costs you thousands of dollars in interest and fees. Smart homeowners want to build equity, not make payments in perpetuity. In addition, you'll end up paying way more for your home than it's worth, which virtually ensures that you won't come out on top when you decide to sell.

Mistake No. 7: Living Paycheck to Paycheck

In March 2018, the U.S. household personal savings rate was just 3.1%, according to Federal Reserve data. Many households are living paycheck to paycheck, and an unforeseen problem can easily become a disaster if you are not prepared. The cumulative result of overspending puts people into a precarious position – one in which they need every dime they earn and one missed paycheck would be disastrous. This is not the position you want to find yourself in when an economic recession hits. If this happens, you'll have very few options. 

Many financial planners will tell you to keep three months' worth of expenses in an account where you can access it quickly. Loss of employment or changes in the economy could drain your savings and place you in a cycle of debt paying for debt. A three-month buffer could be the difference between keeping or losing your house. 

Mistake No. 8: Not Investing

If you do not get your money working for you in the markets or through other income-producing investments, you cannot stop working - ever. Making monthly contributions to designated retirement accounts is essential for a comfortable retirement. Take advantage of tax-deferred retirement accounts and/or your employer-sponsored plan. Understand the time your investments will have to grow and how much risk you can tolerate. Consult a qualified financial advisor to match this with your goals if possible. 

Mistake No. 9: Paying Off Debt With Savings

You may be thinking that if your debt is costing 19% and your retirement account is making 7%, swapping the retirement for the debt means you will be pocketing the difference. But it's not that simple. In addition to losing the power of compounding, it's very hard to pay back those retirement funds, and you could be hit with hefty fees. With the right mindset, borrowing from your retirement account can be a viable option, but even the most disciplined planners have a tough time placing money aside to rebuild these accounts. When the debt gets paid off, the urgency to pay it back usually goes away. It will be very tempting to continue spending at the same pace, which means you could go back into debt again. If you are going to pay off debt with savings, you have to live like you still have a debt to pay - to your retirement fund. (Learn more in 8 Reasons to Never Borrow From Your 401(k).)

Mistake No. 10: Not Having a Plan

Your financial future depends on what is going on right now. People spend countless hours watching TV or scrolling through their social media feeds, but setting aside two hours a week for their finances is out of the question. You need to know where you are to know where you are going. Make spending some time planning your finances a priority.

The Bottom Line

To steer yourself away from the dangers of overspending, start by monitoring the little expenses that add up quickly, then move on to monitoring the big expenses. Think carefully before adding new debts to your list of payments, and keep in mind that being able to make a payment isn't the same as being able to afford the purchase. Finally, make saving some of what you earn a monthly priority, along with spending time developing a sound financial plan.
