10 Deadly Personal-Finance Traps Nobody Tells You About

We all make financial mistakes on the road to financial literacy.

Perhaps you signed up for a credit card on the first day of college without understanding the terms. Or maybe you loaned money to a friend who never paid you back.

However, some financial pitfalls can really damage your bank account and credit score. Avoiding the following traps is vital if you want to build wealth and avoid future money troubles.

This trap is easy to fall into since most credit card companies don't require you to make a large minimum payment every month. Unfortunately, credit card debt is usually attached to a very high interest rate.

Let's say you have $2,000 in debt with an 18% interest rate, and you pay the minimum balance, which is 2% per month. That means it will take you 289 months — or nearly 24 years — to pay off the debt. 

In total, you'll pay $4,396.80 just in interest charges! Way over double the amount of the original debt.

So, crush your debt as soon as possible. It's definitely one of the best ways to get your finances back on track.

A 401(k) is your ticket to financial freedom later in life. You may be able to enroll in one of these plans through your employer as soon as you're eligible. 

If you don't have access to such a plan, remember that you can open your own IRA and save to try and retire stress-free.

The best time to start saving is when you're young. That gives your money more time to compound, which is likely to leave you far richer.

Don't fall into the trap of procrastination. Start weaving a safety net today that will protect you tomorrow. Save as early as possible, and you'll surely thank yourself later.

Adjustable-rate mortgages (ARMs) are not evil. For certain people at certain times, they can be the right tool for buying a home.

But they also can be dangerous. Unlike fixed-rate mortgages, ARMs have interest rates that can climb or fall with time. If the rate climbs fast, you might see your monthly mortgage payment balloon beyond your ability to pay it.

Again, these loans can be good for some people but very bad for others. Look before you leap with an ARM.

Too many folks have learned the hard way that taking out private student loans is often a bad idea.

Private student loans usually have higher interest rates than student loans issued by the federal government. In addition, private loans aren't eligible for federal loan forgiveness programs.

For example, when the government announced sweeping student loan forgiveness, private school loans weren't eligible. That alone underscores the potential danger of using them.

Co-signing on a loan for a loved one might be the right move in some situations. But all too often, it's a pitfall that can ruin your finances.

The main reason? You're legally on the hook for the debt if the person you co-signed for stops making payments. This happens a lot more often than you might think.

Co-signing on a loan also reduces your debt-to-income ratio, making you less attractive to lenders. This can make it tougher to get a mortgage or other loan at the best rates.

That daily morning latte and afternoon sandwich you're buying costs you a lot more money than you think. Sure, they're both convenient and tasty. But is the expense really worth it?

Consider preparing your coffee at home, and you could save at least $50 per month or $600 per year. Making your lunch two times per week instead of spending $10 at your local lunch place could save you $1,040 per year or more.

Is an extra $1,640 a year worth it? How about an extra $16,400 after a decade? I'm sure you could find a good place to invest that money so that it grows.

A timeshare is a property that more than one party owns, and it's shared under an agreement everyone signs. In theory, that doesn't sound so bad.

Buying a timeshare might seem like a good idea when you're sipping drinks poolside on vacation. But don't be fooled.

The reality is that these homes often are marketed to folks who don't have the means to afford them. Plus, timeshares are notoriously difficult to unload, meaning your cash will be tied up in the property for who knows how long.

Unless you're as rich as the rapper Offset — who bought his wife, Cardi B, a Rolls Royce for more than $330,000 — don't fall into the trap of buying an expensive new car.

After all, just because you can finance a car doesn't mean you can afford it. Plus, you're paying interest on that loan. You could easily end up finding yourself desperate to cut your car costs.

Additionally, new cars depreciate steeply the second you drive them off the dealer lot, meaning you're burning through money right out of the gate. So buy a gently used car instead.

Homeownership is an integral part of the American dream, although it can feel out of reach for many people right now. If you're lucky enough to purchase a piece of property, make sure you're buying within your means.

A big part of buying the right home is assessing how much space you'll need. For example, a childless couple probably doesn't need as large a residence as a family might. Shop for a home that won't eat up your monthly income.

If you're squirreling away all of your extra cash in an ultra-safe savings account, you're likely missing out on the opportunity to get ahead financially.

Yes, it's good to have an emergency fund and to keep that money in a safe place, such as a savings account. But the return on investment in a savings account is likely to be low. It's not easy to grow wealthy by putting all of your money into such an account.

Investing a modest amount of money in the stock market will likely serve you better. You'll have to learn to live with the ups and downs of the market, but historically, investing in stocks has been among the best ways to grow wealthy.

The path to financial freedom is long, winding and often littered with traps that can deplete your bank account. The stark reality is that these pitfalls are easy to get into and difficult to escape.

To that end, consider working with a financial advisor who can help you create a plan to build wealth.

Making wise decisions with your hard-earned money is one of the keys to wealth secrets to building financial independence.
