make money without working

0:00 Introduction

1:14 Please Introduce Yourself

Seonwoo Lee is a PhD student in electrical engineering at Georgia Tech. He did his undergraduate at Cornell. He pursued a number of ways to make money without actually having a second job.

1:48 Why have you tried to make money without working?

Seonwoo says that if you do it right, you can make more money per hour than working a traditional job. He says it gives you more flexibility, since you can do as much or as little as you want.

There is some effort involved in pursuing these strategies, but it’s not as much time you would put into working if you had a second job. Additionally, some people are prevented from officially working in other capacities, either by the terms of their contract or by their student visa. The strategies they’ll talk about are probably available to any PhD student or postdoc.

3:07 What are the two topics that we’ll go into detail discussing? What are some other strategies?

Seonwoo will discuss credit card rewards as well as banking sign up bonuses. Second, he’ll talk about the 529 trick to save money on your state taxes.

Emily mentions other ways to make money without working.

  1. Emily has sold items when she’s moved as part of a downsizing process. She has sold items on craigslist.
  2. Another option is Ebates *. Here, you make purchases through the Ebates platform and you are selling your information in exchange for money.
  3. Emily presents short term investing in taxable accounts as an option to make money without working. She and her husband paid off student loans through mid-term investing.
  4. Other options are receipt apps like Ibotta, where you upload your receipts and you sell your information to get cash back.
  5. Also, there is the strategy of “car wrapping,” which is wrapping your car in an advertisement and you receive money based on how much you drive. Emily recommends listening to the How to Money podcast for more information on car wrapping.

7:19 How do the credit card rewards and sign up bonuses work?

Seonwoo begins with the caveat that if you can’t manage credit cards responsibly, you should not pursue credit card rewards in any form. If you pay any interest at all when you do this, you are likely not going to reap the benefits of rewards. Emily adds that you already need a good or excellent credit score to pursue these strategies. If you carry a balance on your credit card, this strategy is not for you. Emily says make sure you are using your credit card like a debit card, and if you are you can consider this strategy.

Seonwoo says that plenty of credit cards offer sign up bonuses. These require you to spend between $500 and $4,000 within the first three months of signing. The bonuses will vary from credit card points to straight cash. The offers will range from $100 to $500 in cash or 30,000 to 100,000 points. Seonwoo says there are ways to meet these minimum spending requirements without spending more than you normally would.

Emily talks about fitting these credit cards into your normal spending. She signed up for a credit card with a minimum spending requirement of $3,000 over three months. She had to put everything she was purchasing on that one card. She picked a time of year when she had to pay for car insurance and flights. She timed signing up for the credit card with when she knew she had above average expenses. Reaching the minimum spend requirements is a hurdle for people with lower income.

Seonwoo says you can see if you can pay your rent with a credit card. He says the fee may be 3%. If that is the only thing stopping you from pursuing a sign up bonus, do the math to see if the rewards are worth it. You can see if you can put tuition or fee charges on the credit card. You can see if you can pay your bills months ahead of time. He says you can buy grocery gift cards to get the charge on the credit card, but then you can spend that gift card over a longer period of time.

Emily says that someone new to this can try it with existing spending, then they can try manipulating their spending.

13:00 Is cash back or points more valuable to a graduate student?

Seonwoo says that cash back is much easier to start with and understand. There are only so many cash sign up bonuses. If you like to optimize things, credit card rewards will be more valuable if you use the rewards for travel.

Emily says that there are cards with a regular cash back rate, like 1-2% back on spending. She says that is a good way to start. Then the next level would be switching to actively pursuing credit card rewards. To make rewards lucrative, you have to be able to redeem them. She explains that in Durham, North Carolina, she couldn’t be loyal to any one airline. But in Seattle, Washington, she makes use of the Alaska Airlines credit card and its reward system.

16:18 What are the pros and cons of the annual fee situation?

Seonwoo says a lot of cards that have sign up bonuses waive the annual fee in the first year. Seonwoo’s strategy is that he signs up for the card, meets the minimum spend requirement, and by month 11 he has decided he won’t pay the annual fee and he will close the card. He says some cards are worth the annual fee, but he wouldn’t recommend keeping the annual fee card to people with lower income.

Seonwoo says that if you cancel within 30 days of being charged the fee, you can often get a refund. Ideally, set up a spreadsheet and reminders to track your credit cards.

18:54 How much money have you made using this strategy?

In his best year for strictly cash, Seonwoo has made about $2,200 to $2,500 from sign up bonuses. He says he has more credit cards and points than he knows what to do with. Most of his rewards have been in credit card points.

Emily says when she was in graduate school and pursuing cash sign up bonuses, she and her husband together made about $1,000. This can alleviate budgetary stress.

20:38 Anything else you want to add on this topic?

Seonwoo brings up how this affects your credit score. In general, when you apply for a credit card, there is a small hit because you have an inquiry on your report. He emphasizes that the point of your credit score is to help you get low interest rate loans or good rewards credit cards. If you’re not applying for a loan in the near future, you can use the credit score for new credit cards. He applied for cards until he started getting denied. He waited a few months, then tried again and got approved. He says people stress out a bit too much about their credit score. He says people should recognize the point of the credit score.

Emily points out that there are positive affects of having several credit cards. She also mentions some cases where you need to keep your credit score high, like when you apply for a new residence or take out a mortgage.

24:24 How do banking sign up bonuses work?

Seonwoo says that the main difference is that instead of requiring you to spend money, banking sign up bonuses require you to already have money. You sign up for a new checking account, get a couple of direct deposits in there and keep it open for at least six months, and sometimes make some transactions. You can get between $100 or $350 for signing up for that account. Some have fees, but the bank may waive the fee for students or on other terms.

Emily mentions minimum balances, and Seonwoo clarifies that high balances requirements are usually for savings accounts. Checking accounts have minimum balance between $1500 and $3000, and the percent return is 10% to 20% in six months. This is a good option for your emergency fund.

Seonwoo recommends the blog Doctor of Credit, who has several blogs on these topics.

28:54 What is a 529? What are the benefits of it?

Seonwoo explains that there are two types of 529 plans. One is a prepaid tuition plan, which he is not talking about. The other type is an investment plan. At both the state and federal level, it is not taxed when you withdraw it for education expenses. Emily compares this to an IRA, where you are not taxed on the growth of the money if you use it for retirement. Seonwoo calls it a Roth IRA for education.

Seonwoo says 30 states and the District of Columbia offer a state income tax deduction for contributing to your 529 plan. Most states require that you have a plan with that state, but they don’t require a net contribution for the year. He says you can contribute the money to get a deduction, then pull it out to pay for your expenses.

Emily says cost of living expenses can be considered qualified education expenses for the 529 plan. She explains that you can put money into a 529, then take it out to pay rent, and then you get a state tax deduction or credit. Seonwoo says even if your living expenses are $0, you can still do this. The amount is set by the university’s financial aid office room and board estimate of the cost of attendance.

Seonwoo explains his specific example at Georgia Tech. The financial aid office lists the cost of attendance estimate for room and board as more than $10,000. In Georgia, a single taxpayer can deduct up to $2,000 of a 529 contribution. His marginal tax rate is 6%, so a deduction of $2,000 saves him $120 per year in state taxes. So, he contributes $2,000 to the 529 plan and leaves it in there for 10 days, then he takes it out. This is all it takes to get the tax deduction.

36:37 Where can we go for more resources?

Seonwoo says he learned about this by going through his state tax return to look for deductions. On his blog, he has a college tag and he has a post about the 529. The site Saving for College is a good resource for 529 plans.

Emily says this is a strategy that you need to investigate for your own state. Seonwoo mentions that there are other education credits and deductions available, but you can’t double count expenses. This 529 trick makes use of the living expenses, because this is unique to this tax benefit.

Seonwoo recommends printing to PDF the page from the financial aid office that documents the cost of attendance. This is documentation to keep if you’re audited.

How to Successfully Plan for Retirement Before and After Obtaining Your PhD

April 8, 2019 by Jewel Lipps

In this episode, Emily interviews Dr. Brandon Renfro, a finance professor and financial advisor. Brandon shares the tortuous path that led him to his current faculty position at East Texas Baptist University and side business in retirement advising. They discuss the long-term financial effects of doing a PhD – both positive and negative – and how to have a successful retirement even if you can’t save (much) during your PhD training.

PhD plan for retirement

0:00 Introduction

1:05 Please Introduce Yourself

Dr. Brandon Renfro has a PhD in Finance. He is both an academic and a practitioner. He advises retirement advising for individuals. He does financial planning while being a tenure track professor.

2:02 What was your career trajectory?

Brandon says that he “walked backwards” or stumbled into his PhD. As an undergraduate, he planned to go to law school. He was advised to major in business in preparation for law school. He took an American enterprise course and saw a presentation about the time value of money in the retirement planning context. This presentation inspired him, so he majored in finance and loved it. He went to law school but says he crashed and burned. He was in the military and had GI bill benefits. He decided to use his GI bill benefits for an Master of Business Administration (MBA). He asked his MBA advisor about adjunct teaching. He had to have 18 graduate hours in the discipline to teach a course. He discovered he loved teaching. He decided he wanted to teach full time. He feels fortunate that he got a tenure track position at a liberal arts college in Louisiana, where he worked for three semesters. Now he is in his third semester at East Texas Baptist.

Emily points out that Brandon tried stuff and saw what stuck. Brandon agrees that this is important to explain to students today. He says many students set a goal and stick to it no matter what, even if the path isn’t right for them. He says there is a time when you should recognize if you don’t love what you’re doing and you should try something different. Brandon says he would tell his 18 year old self to major in finance, but at the time it didn’t occur to him.

Emily asks how Brandon handled the sunk costs of going to law school. Brandon clarifies that he didn’t meet the GPA requirements to continue law school but he wasn’t sad about it. He says he was miserable in law school. He had taken out loans to pay for the year in law school. He says it was $20,000 that he spent to learn that he didn’t want to be an attorney. He says if he looks at it like it’s money he spent to learn that he loves being a finance professor, it was worth it.

7:47 Given that a person has decided to do a PhD and maybe a postdoc, what are the effects of their financial outlook?

Emily starts by explaining that graduate students, postdocs, and early career PhDs have a lot of anxiety around saving for retirement. Most of these people are in their 20s or 30s and they know they are supposed to be investing for retirement. But planning for retirement feels overwhelming in the context of their competing financial demands, like student loan payments or saving for a house down payment, coupled with their suppressed income for an extended period of time.

Brandon says that if you put off starting a career to do a PhD, this will make saving and preparing for retirement a little more challenging. These are foregone years of savings. However, academics have the ability to work past typical retirement age. As a professor, you can work longer and save money for retirement for more years, even if you start work and start saving a little later in life. Emily clarifies that PhDs can add years on the back end, instead of on the front end, to the total years that they can work to save for retirement. PhDs can do this because their work is fairly intellectual, and hopefully they get better with time. It’s less daunting to add years at the end in these career paths than others. Brandon says it’s (physically) easier to talk about what you know than it is to work on a factory floor, and you can prolong the years you do this kind of work. Even as PhDs reach retirement age, they have options to be an instructor, lecturer, adjunct, or consultant. You can work less than a full time load, and still capitalize on your years of experience.

Brandon says even while you’re working in your 30s or 40s, you have the ability to leverage expertise outside the classroom. Even if you are working a full time tenure track position, you have a lot of knowledge that you can leverage in industry, even while you’re teaching. Emily shares that when she was an engineering PhD student at Duke University, she saw plenty of professors had consulting businesses or wrote books. In academia, there are many ways to step outside your primary role and leverage your expertise. Emily says that there are plenty of opportunities to have side hustles all through your career. She is part of a community of self employed PhDs, and many people’s self employed job is on the side of their full time job. Brandon believes there is a lot of potential for academics to be self employed. He says even if you were the lowest ranked student in the lowest ranked PhD program, you still have knowledge and you are already part of a select group. Emily says any PhD can find a market where their skills are valuable. They give examples of formatting and copy-editing and tutoring.

17:13 How can someone handle the income jump after the suppressed income period of being a trainee in a PhD or postdoc?

Brandon says in one phrase, avoid “lifestyle creep.” When you suddenly go from an undergraduate or PhD student lifestyle based on lower income to receiving a full time income, you need to be mindful to not immediately start living at the new income. He says you don’t need to be extremely frugal, but use a moderate amount of your new income to build your emergency savings, pay down consumer debt, and pay down student loans in order to be much better off in the long run.

Emily shares the standard personal finance advice to commit a large percentage of your raise to your financial goals. Either all of the raise or as much of the raise as you can, put it towards goals instead of your consumption spending. She says it applies even more when you have a large income jump. Most of it should be used to accelerate financial goals. When Emily and her husband finished their PhD programs, they applied this concept to their new “real jobs” income. They had several financial goals that they focused on and avoided lifestyle creep.

Brandon shares his story about buying a house. He was unsure where he would get his tenure track position, but he wanted to build equity without committing his family to a large mortgage payment. He bought a small rent house before they bought a house to live in. Emily brings up that some people rent their properties as they move, in contrast to how Brandon purchased the property purely as a rental property.

23:40 Grad students and some postdocs don’t pay into the social security system. What are the long term effects of missing out on these years of contributions?

Brandon explains that social security benefits are based on 35 years of covered earnings. Essentially, it’s an average of your highest 35 years of earnings. If you’re starting to contribute later, do the math. If you’re in your early 30s, you may be in your late 60s before you have 35 years of covered earnings. The issue is that your benefit will be calculated with some zeros in the 35 year average, which skews down your average. When you’re on the back end of your career, this may influence your decision to work for a few more years to replace some of the years where you contributed zero dollars to social security.

26:59 What steps can someone who’s in or recently been in PhD training do to mitigate negative effects of lower income and not contributing to retirement?

Brandon brings up the psychological benefit of being used to living on a small income. He says to continue to live like that for a couple of years so that you can build yourself a financial cushion and start saving for retirement. He says eventually the feeling goes away and you get used to the new level of income. Psychologically, it’s harder to start saving for financial goals later.

Emily says that this is classic personal finance advice. Sometimes the lifestyles of PhD students are lower than those of college students. She says it’s difficult to deflate lifestyle. You might see the higher paycheck from your first real job, then you lock yourself into higher housing costs or buy a new car. It’s difficult to take a step back, but it’s much easier to keep a similar lifestyle and put the new income to your financial goals and slowly work up your lifestyle.

30:16 If a person starts saving during graduate school, what kind of effect can that have on retirement?

Brandon explains the first presentation that he saw on the effect of compound interest. If you started when you were 18 years old and you saved just $2,000 per year in a retirement account, you would have a million dollars for retirement if you simply earned the average market return. He says the same is still true if you start at 30 or 32, but there are a few less years for compounding to take effect.

Emily says that even during graduate school, saving a couple hundred dollars a month is accessible. It’s not a thousand dollars every month that you need to save. The earlier you take these steps, the more and more impact it can make. It really does make a difference to take these steps earlier.

Brandon adds that at least, don’t make negative steps. Buying a cheaper car or cheaper clothes can go a long way. Emily says that the professional students, like law students, were living a higher lifestyle even though they were living on loans. She says the smallest amount of debt that you have to take on during training will make it easier for you in a few years.

35:50 What do you do for clients?

Brandon can help with anything within realm of retirement planning. He can help someone starting out. He can help graduate students and postdocs sort through their different options for retirement plans. He can help with decisions about how to invest within retirement plans. Brandon encourages you to take retirement very seriously and to think very hard about putting off retirement. He says it’s really hard to make a strong case against contributing to a plan with an employer match. He says employer match is essentially free money. Emily says an employer match is a 50% or 100% return on investment.

Emily clarifies that someone looking at different options can ask Brandon for help considering which option to prioritize. Brandon can help overcome “analysis paralysis.” Brandon says something is almost always better than nothing, and you need to just do something. He encourages you to envision your retirement and what your financial goal looks like.
