What's Your Number? 5 Financial Figures You Need to Know

US News

When we talk about personal finance, we toss around a lot of terns: APRs, credit scores, mortgage principals... you get the idea. It's easy to get lost in all these numbers, so we're here to break it down for you.

These five may be the most important. They're the difference between a healthy bank account and debt collectors knocking at your door.

1. Your credit score. This may be the most important number ever attached to your name. Your credit score decides your approval for a mortgage or auto loan; it also plays a role in what credit card offers you qualify for. It influences your interest rates on loans, too, and much more. Moreover, many employers evaluate an applicant's score during the hiring process.

To build a high score, you have to be a responsible borrower. That job is a little more complex than it might sound, so we'll start at the beginning: Pay your credit card bills on time and in full.

Once you've got that down, another way to boost your credit score is to take out different types of loans to impress lenders. Their thinking is: If you can handle such responsibilities, you're creditworthy.

That said, don't take out all those loans at the same time, as each results in a hard inquiry, which takes a slight hit on your credit score. Your length of credit history has an impact on your score, and too many accounts opened at the same time may make creditors think you're desperate.

2. Your tax rate. When you file taxes this year, you'll find yourself in one of six brackets, from 10 to 35 percent. Don't assume, though, that if you fall into the 15 percent bracket, you pay a flat 15 percent to the federal government every year--you'll pay less.

That's because the 15 percent bracket isn't your effective rate (the final amount you end up paying); it's your marginal tax rate, which says how much your last dollar is taxed.

Confused? Think of taxes as a stepladder: for single people, the 10 percent bracket ends at $8,700. The next rung on the ladder is the 15 percent bracket, from $8,701 to $35,350.

If you made $30,000 last year, the first $8,700 you made is taxed 10 percent; and the rest, that other $21,300 you earned, it taxed 15 percent. In sum, you end up paying $4,065, which means, again, your effective rate isn't 15 percent but rather 13.55 percent, assuming you don't claim any tax deductions, credits, or the like.

Here's why this is important: If your employer withholds significantly more than you owe to the federal government, you might ask them to withhold a little less. That way, rather than get the extra cash back as a federal tax return in springtime, you can deposit the money into a savings account right away and start earning interest.

3. Your personal saving rate. In America, saving a large portion of your earnings may be a thing of the past. The personal saving rate--how much of your disposable income is socked away rather than spent--is at just 4.6 percent as of the fourth quarter of 2012.

While this is much improved from a shocking low of 1.5 percent in 2005, it still represents a major decline from decades past, when Americans overall saved more than 10 percent of their income. What's worse, in 2010, according to the Federal Reserve, just 52 percent of Americans spent less than they earned.

With interest rates so low, it's no surprise people aren't depositing as much as they used to. Even long-term CDs, which are normally much higher-yield than the everyday savings account, aren't returning much; on average, CD rates are below 1 percent APY. Nonetheless, consumers aren't out of options. If you're looking to save, check out online banks or local credit unions, which typically offer better rates than the big banks.

4. Your student loan debt. Americans hold more debt in student loans than in credit cards, to the tune of $1 trillion. Although interest rates on most federal and private loans are less than those for credit cards, the shear amount of debt--sometimes as much as $100,000 or more--can make it difficult to afford even the minimum payments. Be sure to know your future obligations when taking out student loans, and take advantage of any beneficial repayment programs offered by your lenders.

You need to get a handle on your student debt, as it will affect the loans you take out in the future. The way you treat your student debt, and really any debt, has a bearing on your credit score, which in turn has a bearing on your interest rates--or if you'll be approved for the loan at all.

5. Your net worth. It sounds daunting to try to put a dollar value to your name, but knowing this value will help you set smarter goals and create a sound financial plan. To calculate your net worth, you need to make a list of everything you own, everything you owe, and then subtract to find out the difference.

First, add up your assets, then your liabilities (or your total debts). Your rough net assets equation should be as follows:

Net worth = (cash + properties + investments) -- (credit card debt + loans + outstanding payments of any other kind).

If you're in the positive, ask yourself: "Am I allocating my resources as best I can to my short-, medium-, and long-term goals?" If all of your money is sitting in a low-yield savings account, hardly beating inflation, consider investing a portion of it to diversify your portfolio.

If you're in the negative, don't stress but rather develop a plan. The most important step you can take is to begin paying off your debt as soon as possible, starting with the loans that are charging you the most in interest.

Once you know where you stand overall, you can budget better for future expenses, such as preparing to buy a car or saving for retirement.
