Five Big Money Decisions, Run Through the Numbers: Ramit Sethi on Travel, Houses, Rings, Parties and Moving Out

Open on YouTube ↗
Overview

Ramit Sethi, author of I Will Teach You To Be Rich, works through five real questions people sent him about major financial decisions. The questions are whether to quit a job to travel, whether to buy a house and have a baby, whether to buy an engagement ring, whether to spend on a 40th birthday party, and whether to move out of a parents' home. For each one, Sethi reviews the person's numbers, questions their assumptions, and gives his own recommendation. His opening claim is that the right answer is often counterintuitive. In several cases, the person who seems to be doing everything right is the one he thinks needs to change course.

Sethi sorts each person's money into the same categories throughout: assets, investments, savings, debt, "fixed costs" (essentials such as housing, debt payments, groceries), investing, saving, and "guilt-free spending." He refers to his own guideline that guilt-free spending should be about 20–35% of take-home pay.

Case 1: A 25-year-old with $773,000 invested who wants to travel for a year

TM is 25, lives in Sunnyvale, California, and works as a product manager earning about $200,000. They have long wanted to travel the world for an extended period, but limited paid time off has made that impossible. They have been putting money into a dedicated travel fund and say they have had "outsized returns" on their investments. They are not sure they want to return to the same career afterward. Their idea of a rich life involves more flexibility and fewer meetings. They also doubt they could keep a high income if they changed direction.

The numbers surprised Sethi:

  • Investments total $773,000.
  • About 63% of gross income goes to investing: $23,000 a year to a 401(k), $5,000 a year to an HSA, and roughly $8,000 a month after tax on top of that.
  • Savings are $50,000, with $450 a month going to the travel fund.
  • The only debt is $1,768, which Sethi guesses is a credit card bill that will be paid in full.
  • Fixed costs are only 20%, which makes Sethi suspect TM lives with their parents.
  • Guilt-free spending is $724 a month, about 6%.

Sethi's reading is that TM is "way over saving, way over investing." He jokes that they probably turn down invitations from friends because they need to put $8,432 toward retirement that month.

He draws on his own experience. He also earned a lot in his 20s and invested heavily. Looking back, he says the one thing he would change is to have had more fun. He would still have invested aggressively, but he would have set aside something like $200 a month, or even a week, for special occasions that can't be recovered later in life. He likes that TM seems willing to cut day-to-day spending in exchange for one big, meaningful trip.

Sethi sees TM framing the choice as career versus freedom, and argues the answer can be "yes and yes." He compares it to college application FAQs he read in high school. Those FAQs addressed whether to take an easier class and get an A or a harder class and get a B. The colleges' answer was that admitted students take the harder class and get the A. Applied to TM, the question becomes how to have both a rewarding career and a life with travel. On the complaint about meetings, Sethi notes that after the trip TM could look for a role with fewer meetings, and says such roles exist.

Then he runs projections. If TM keeps contributing about $126,000 a year for 40 years, Sethi's figures show about $38 million at 65 in inflation-adjusted terms, or around $96 million in nominal dollars. If TM stopped investing today and contributed nothing more, the figures are about $11.5 million in real terms and $34.9 million nominal. Sethi's conclusion is that someone headed for tens of millions who is still agonizing over one trip has gone too far. TM could cut contributions by $10,000, $20,000 or $50,000 a year or more and still be very wealthy. In his words, TM has already won the personal finance game at 25, and the new game is building a rich life.

Case 2: A $1.2 million house and a baby within two years

Sally is 32 and lives in the Bay Area. She is an account manager, and her husband Brett is a program manager. They want to buy a $1.2 million house in the next two years and start a family around the same time. They worry about being stretched financially. They have traveled a lot and are willing to cut back on that, but Sally still wants to feel secure, and she thinks she may need to help her parents financially someday.

Their numbers:

  • Assets: $70,000. Investments: $314,000. Savings: $195,000. Debt: $18,000.
  • Fixed costs: $6,916, or 44%. Housing is only 14.6% of gross income.
  • Investing: $1,800 a month (11%).
  • Saving: $2,400 a month (15%), of which $2,000 is earmarked for the house.
  • Guilt-free spending: $4,712 (30%).

Sethi praises the low fixed costs, which give the couple a lot of margin. He notes that much of the extra money is going to guilt-free spending, near the top of his 20–35% range. He says that is fine, but it tells him where the money is going.

He then models the purchase. With 20% down ($240,000, which could come from savings, investments, or a smaller down payment), the loan is $960,000. At 7%, the mortgage is about $6,390 a month. Once he adds "phantom costs" such as maintenance and transaction fees spread over the life of the loan, he estimates $7,200 to $7,800 a month. For the baby, he estimates childcare at about $2,000 a month plus $500 to $1,000 for supplies and medical costs, for $2,500 to $3,000 in total. Together, housing and baby would put fixed costs at roughly $9,500 to $10,500 a month. That is over 60% of take-home pay before groceries, saving, investing or guilt-free spending.

His verdict is that right now they cannot afford both. He gives three reasons: the house is expensive, a 7% rate adds a large amount of interest every month, and even with 20% down their income can't support the house and a baby together.

He also names what he calls one of the most common financial mistakes, which is taking on several large new costs at once. The typical example is buying a house and a new car while having a baby. His alternative is to slow down and ask whether the house or the SUV has to happen now, or whether it can wait 6, 12, 18 months or longer. Spacing out new expenses gives people time to recover financially from each one.

He also pushes Sally to define what "security" means. It might mean owning a house, though he points out she won't own it outright for 30 years. It might instead mean having a large cash cushion so that if a landlord ends the lease, they can handle it. He argues Americans tend to treat homeownership as the only route to security when there are many others.

His recommendation is to stay in their current low-cost home as long as possible, since every month there saves thousands of dollars. The more important question is what they do with that money. If they really want to buy at current prices and rates within a reasonable timeframe, 15% saving isn't enough. He suggests moving $1,000 or even $2,000 a month from guilt-free spending into savings. He also wants them to question the two-year timeline and consider whether the purchase could happen in five, eight or ten years, then allocate their money to match.

Case 3: A 33-year-old in debt who wants an engagement ring

John is 33, lives in Miami and works as a product manager. He is supporting his girlfriend Jill while she completes an accelerated RN program, and he is also helping his mother, who has Alzheimer's. He wants to save for an engagement ring and build a six-month emergency fund. He asks how to get out of the hole and says, "I feel like I am drowning."

His numbers:

  • Assets: $0. Investments: $95,000. Savings: $10,000. Debt: $47,300.
  • Fixed costs: $7,100, or 75%. Housing is 26% of gross, which Sethi considers good.
  • Debt payments total $1,370 a month: $500 to credit cards, about $650 to a debt consolidation loan at almost 8%, and $220 to student loans.
  • Groceries are $800 a month, and "miscellaneous" fixed costs are $816.
  • Investing is zero, saving is $705 (7%), and guilt-free spending is about $1,600–$1,683 (18%).

Sethi says John can transform his finances but will have to make very hard decisions. The feeling of drowning comes from fixed costs being too high, and the cause is the debt. Based on the types of debt, Sethi infers that John has had a poor relationship with money. He says people commonly end up with credit card debt and consolidation loans when they have an overspending problem. He says he is "almost certain" John hasn't been in control of his money, guesses he has never read a personal finance book, and says he clearly hasn't automated his finances.

He ties this directly to the ring. John cannot afford an expensive ring right now. Maybe something modest, a few hundred dollars, is possible. The real question is whether John is willing to have that conversation with his partner.

Sethi then goes line by line. Groceries at $800 may be reasonable in general but need to come down while in debt, by $100 to $200 redirected to the debt. The $816 in miscellaneous spending gets his strongest reaction; he calls it indefensible for someone in debt. He says to cut it to about $100 as a buffer for things that come up, freeing roughly $700 a month for debt payoff and savings. Guilt-free spending at 18% is "nice for me, not for you," he says. Sethi has no debt and can afford that, but John can't. Although Sethi usually recommends 20–35%, for John he would cap it at about 10–11% and send the rest to savings and debt. He says a debt payoff calculator would show John can shave years off repayment with these moves. The shift, as he frames it, is from feeling overwhelmed to "ferociously attacking" the problem, becoming debt-free within a few years and then moving on to saving and investing.

He also acknowledges John's mother's illness, expresses sympathy, and calls John's support of her laudable. Financially, he expects the cost of her care to rise over time and says large, unexpected bills are inevitable. His advice is to build a bigger buffer through a dedicated "medical unexpected expenses" savings account funded every month.

His order of priorities is savings first, then debt, then the ring. He says the ring matters, but what matters about it is the symbol, not the size or ornateness of the diamond. The symbol is whether John can talk candidly with his partner, take responsibility, explain his plan, and ask if she is willing to join him on that path.

Case 4: $40,000 for a 40th birthday party abroad

Philly Crist is a 38-year-old business analyst. They describe themselves as a hardworking immigrant who grew up as an orphan in Africa. For five years they have saved and invested while also helping their family. For their 40th, they want to throw a party abroad for family and friends, with a maximum cost of $40,000. They ask whether that's crazy and whether it would set them back significantly.

Sethi calls it a "cool and provocative question" and shares his own story. When he turned 40, he realized there are few chances in life for a big party, and he wanted to make the most of them. He invited friends and family to a resort in Mexico, told them all they had to do was show up, covered everything else, and calls it a memory he will never forget. His gut reaction is that Philly Crist can afford it, but he checks the numbers.

Their numbers:

  • Assets: $60,000, which is a car. Investments: $340,000. Savings: $40,000. Debt: $30,000, the car loan.
  • Fixed costs: $4,967 (62%). Housing is 17% of gross. The car costs $1,050. Groceries are $400, clothes $200, family support $300, subscriptions $400, and miscellaneous $237.
  • Investing: $1,000 a month (13%), on top of maxing out a 401(k) and HSA.
  • Saving: $950 (12%). Guilt-free spending: $1,084 (14%).

What stands out to Sethi is that the goal is big, audacious and centered on the person's rich life. The monthly money sent to family makes their priorities clear. He also notes the goal isn't a suit or golf clubs. It is bringing loved ones together, and probably paying for some who couldn't otherwise attend. He finds that inspiring.

He says that if the party were happening today, he would probably advise against it. But there are two years left, and Philly Crist is already putting $400 a month toward it. Continuing that would give about $5,000 a year, or roughly $10,000 of the $40,000 by age 40. The bigger factor is a $50,000 bonus mentioned as a side note but not included in the spending plan, part of which could go to the party.

For Sethi, the deciding question is whether the person will have enough to retire. If not, they can't take the extravagant trip; if so, they should go ahead. His assumptions are $340,000 already invested, about $42,000 a year in contributions (the $1,000 monthly plus roughly $26,000 to the 401(k) plus the HSA), 27 years until 65, and a 7% return. The result is about $5.4 million, which he says would support over $218,000 a year in safe withdrawal income. His answer is yes, they can afford the party. He says he is confident, from how the person talks, that they will reach that outcome, and he predicts they will be grateful later that they celebrated with loved ones at 40.

Case 5: A 23-year-old with $130,000 in student loans who wants to move out

The last question comes from a 23-year-old engineer in Orange County, California. She is a recent graduate a few months into what she calls her dream job. She graduated with just over $130,000 in student loans and earns $115,000 a year with up to a 20% annual bonus. She contributes enough to get her employer's 6% 401(k) match, maxes out her Roth, puts $400 a month into an emergency fund, and pays $4,000 a month toward her private loan. She can do this because her parents let her live with them at essentially no cost, in exchange for cooking, errands, chores and helping with her younger siblings. At this rate she could be debt-free in about three years. She had thought about moving out with her partner, but seeing how $1,500 a month for rent and utilities would stretch her payoff timeline made her hesitate. She asks whether she is stupid for considering moving out in a year.

Her numbers:

  • Investments: $3,000, which Sethi finds surprisingly low given her contributions. Savings: $5,000. Debt: $130,000.
  • Fixed costs: $4,815 (77%). Sethi first finds this very high for someone with no living expenses, then realizes the student loan payments are inflating it.
  • Investing: $610 (10%). Saving: $675 (11%).
  • Guilt-free spending: $150 a month (2%).

Sethi sees himself in her. As a teenager living with his parents, he worked at a pizza place, as a soccer referee and at a tech job. He estimates his savings rate at about 93% and says he invested that money aggressively, and it has grown substantially over 30 years.

He praises her for using a rare opportunity. He says many people reflexively dismiss living at home as something "for losers," while in many countries it is normal after graduation. He credits her with the courage to do it and guesses she has a good relationship with her parents. He also highlights a principle he says many people miss: when you save money by cutting something out, what are you doing with those savings? People often talk about skipping coffee but have no plan for the money. She, by contrast, is sending it straight to her loans.

The detail that stands out most to him is the three-year payoff. He calls clearing over $100,000 of debt in three years amazing, and also "really aggressive." That is where he reframes her question. Would she accept stretching repayment to four, five or even seven years in exchange for the life she wants now? He acknowledges the financial cost is more interest. But he asks her to imagine being 60 and looking back. Would she be happier to have paid off the debt in three years? Or to have eased off slightly, paid it off in about five and a half, and in the meantime lived independently with her partner, traveled, and done the things that mattered to her?

Sethi says that to him the answer is obvious. When someone is paying off debt very aggressively, easing back just a little can open up a whole new part of their rich life, one she has already said she wants. He adds a cultural point: some 23-year-olds would do anything to move out, while many people from other countries, including India, find it normal to live with parents at 23, 25 or 28. His own parents would have been happy if he had lived with them until he married. In the end, he says, the choice is hers, and the good news is she has options.

The pattern across the cases

Sethi does not apply one rule to all five people. The two he thinks are over-saving, TM and the young engineer, are told to ease off. The couple with low fixed costs is told they can't afford their plan yet and should slow down and rethink what security means. The person drowning in debt is told to cut spending hard and put the ring after savings and debt. The person planning an expensive party is told to go ahead, because the retirement projection supports it.

In each case, his method is to lay out the full numbers, identify the one factor that actually decides the question, and weigh the choice against what the person says they value. He closes by noting that it's easy to judge other people when watching examples like these, but every one of these decisions made sense to the person asking.
