Getting a grip on your financial life can feel overwhelming when you’re launching into your adult life, as many new graduates are doing now.

Most people don’t give a lot of thought to the fundamentals sooner than they need to: obtaining health insurance, paying off debt, contributing to retirement plans, building an emergency cushion, learning your credit score and improving it.

For some advice to young adults who are starting to zero in on these key financial tasks, we sat down with Beth Kobliner, a personal finance expert and author of the newly revised classic guidebook “Get a Financial Life: Personal Finance in Your Twenties and Thirties.”

For decades, Kobliner’s expertise has centered on the core ABCs of managing your money. She even taught Elmo about money on Sesame Street.

Despite having a job in hand and possibly an employer-provided 401(k) plan, the uncertainty of the economy, sky-high home prices, and the capriciousness of the market would make anyone edgy about their money decisions, let alone young adults just starting out.

Kobliner spoke with Yahoo Finance about her advice. Here are edited excerpts of our conversation:

Kerry Hannon: What are your core financial rules for someone to evaluate their current saving and spending habits?

Beth Kobliner: My rough financial rules to know if you’re right on track, wildly off base, or somewhere in between are:

Your debt payments (not including your mortgage, if you have one) should be less than 15% of your monthly pretax pay.

Spend no more than 30% of your monthly take-home pay on rent or mortgage payments. This rule is something to shoot for but not really attainable if you live in a major city like New York, San Francisco, or Washington, D.C., where you might need several roommates to even come close.

Save at least 10% of your take-home pay each month. It’s critical to think of your savings as a fixed monthly expense that’s part of your budget, just like your car payments or rent.

Realistically, these targets may not always be possible to hit, especially if you’re just starting your career, but they’re good guidelines to keep in mind.

Why is time so important to people at this stage when it comes to their money?

When you’re young, money grows exponentially if you invest even small amounts in tax-deferred retirement accounts. But you need to do it in a methodical way and save it over long periods of time. That magic of tax-free compounding, as tough as times are for young people today, is the best way to ensure you'll have some money down the road.

How is the financial arena different from when you first wrote your guide for young people?

Young people today want to make a lot of money quickly. They may be living paycheck-to-paycheck, and they're looking for quick answers. With social media, these quick answers seem to be pretty easy. There's always this desire to find the best stock rather than investing in a low-cost index fund. The best way to lose money is to try to make it quickly, and you might suffer a really big loss that takes so long to recover from.

The basics are the same: Stay out of debt, save in a long-term retirement plan—even though it has the word retirement, it's actually a super smart investment plan—and invest in low-cost index funds.

What are some of the particular challenges this age group is encountering?

They have more in student loan debt than previous generations. They have higher credit card debt than their parent’s generation at this age, too.

The other big thing is the job market. That started a few years ago. For the first time in decades, college graduates' unemployment rates are worse than the average population's. That has been really difficult for young people.

That's a big historical change. And of course, people who don't go to college are having an even worse time.

Any simple advice on paying down debt?

One of the smartest financial moves you can make is to take any savings you have (above and beyond money you need for essentials like rent, food, and health insurance) and pay off your high-rate loans.

The reason is simple: You usually can “earn” more by paying off a loan than you can by saving and investing. That’s because paying off a credit card or high-rate loan that has a 20% interest rate is equivalent to earning 20% on an investment —an extremely attractive rate of return.

Is there one main thing you would advise people to do to raise their credit score? 

The most important thing you need to know about keeping your credit score high is don't miss payments. And if possible, the fundamental thing that really matters is paying off your high-rate debt in full each month. So many young people think they need to carry debt on their credit card because that boosts their credit score. That is not true. That is a myth.

For someone graduating this year, what are the best moves to make in terms of their financial life?

Try to get a job. If you can live at home with your parents while you look, do that. If the job has a 401(k), you probably are already signed up for it; if not, do that. If there's a matching amount of money from your employer for the dollars you put in, at least save enough to max that out. Don't get into credit card debt. Make sure you know what your student loans are and do not miss payments on them.

If you do those things, you're very much on your way.
