10 Things I Wish Someone Told Me About Money When I Was 20

 

 

If I could go back in time and sit down with my 20-year-old self, I wouldn't talk about relationships, career advice, or any of that. I'd talk about money. Because every single financial struggle I went through in my mid and late twenties — the debt, the stress, the shame, the panic — could have been avoided or at least softened if someone had just sat me down at 20 and told me what I'm about to tell you.

Nobody did. Not my parents. Not my school. Not my friends. We all stumbled into adulthood and figured it out through expensive, painful trial and error.

Here are 10 things I desperately wish I understood about money before I turned 21. Some of these are practical. Some are emotional. All of them are things I learned the hard way, and I'm sharing them so you don't have to.

1. Nobody is Going to Teach You This Stuff

This is the thing that made me the angriest once I figured it out. We spend 12 years in school learning geometry and the periodic table, but nobody sits us down and explains how credit card interest works. Nobody explains what a credit score is and why it matters. Nobody tells you what compound interest can do for you or against you.

4 More than half of American adults never talked about finances growing up. I was one of them. Money was not a topic in my house. The only thing I learned about money from my family was "we don't have enough of it" and "don't ask about it."

So I walked into adulthood completely blind. I got my first paycheck and my first credit card within the same month, and I had absolutely no idea how to handle either one. The paycheck felt like free money. The credit card felt like more free money. Neither was free. I just didn't know that yet.

If you are reading this at 18 or 20 or 22, congratulations. You are already ahead of where I was. The fact that you are seeking out money advice puts you miles beyond most people your age. Most people won't Google this. You did. Remember that.

2. Your Income is Not the Problem (Your Habits Are)

For years, I thought that if I could just make more money, everything would be fine. Get a raise. Get a better job. Pick up more shifts. The problem would solve itself.

Then I got a raise. A real one. And within two months, I was just as broke as before. Because my spending expanded to match my new income. I got a bigger paycheck, so I ate at better restaurants. Upgraded my phone. Moved to a slightly more expensive apartment. By the time the dust settled, I had more money coming in but the same amount going out, and the same $0 in savings.

This has a name. It's called lifestyle inflation. And it is the silent killer of wealth in your twenties. 14It's tempting to equate a bigger paycheck with financial success. But earning more doesn't mean you're building wealth — how much you keep and where you put it matters more.

The fix is stupidly simple but hard to actually do. Every time your income goes up, your savings should go up by the same amount or more. Got a $200 per month raise? Increase your automatic savings transfer by at least $100. Live on the same amount you were living on before. Let the raise build your future instead of inflating your present.

3. Compound Interest is Either Your Best Friend or Your Worst Enemy

This is the thing I am most angry about, not understanding at 20. Compound interest is the most powerful force in personal finance, and it works for you or against you depending on which side of it you are on.

If you are saving and investing, compound interest is incredible. 12Compound interest isn't magic — but it might be the closest thing we have. If you start saving $200/month at age 25, you could end up with more than someone who saves twice as much starting at 35. That is not a typo. Starting earlier with less money beats starting later with more money because time does most of the heavy lifting.

But here is the flip side that nobody warned me about. If you are in credit card debt, compound interest is working against you. The bank is earning compound interest off YOUR debt. That $3,000 credit card balance at 24.99% APR is growing every single day you don't pay it off. The bank is getting richer off your debt while you are getting poorer. That is not an accident. That is the business model.

At 20, I had no idea how any of this worked. I thought interest was just a small fee the bank charged. I didn't understand that it compounds daily on credit cards. I didn't understand that $3,000 in debt could cost me $5,400 if I only paid the minimum. And I definitely didn't understand that $100 a month invested at 22 could turn into over $200,000 by retirement.

If I could tattoo one piece of financial advice on my younger self's forehead, it would be this: get compound interest working FOR you as early as humanly possible. Every year you wait costs you thousands.

4. Your Credit Score is Not Optional (It Controls Your Life)

At 20, I didn't even know what a credit score was. I'm not exaggerating. I had no idea there was a number attached to my name that banks and landlords and insurance companies and employers were looking at to decide whether they trusted me with money.

16 Credit isn't something most people talk about openly, which is part of the problem. I've met so many people who felt blindsided by how much their credit score affected things like car loans, apartment applications, and insurance rates.

My credit score at 23 was 580. That is bad. Really bad. And it didn't get that way because of one big mistake. It got there through a bunch of small ones. A late payment I forgot about. A credit card I maxed out. A medical bill that went to collections because I didn't open the mail.

Every one of those things stayed on my credit report for 7 years. Seven years. One missed payment at 21 was still haunting me at 28 when I tried to get an apartment, and the landlord almost rejected me.

Here is what I wish someone had told me. Your credit score is not some abstract number that only matters when you buy a house. It matters right now. It affects the interest rate on your car loan, which could cost you thousands extra over the life of the loan. It affects whether you get approved for an apartment. It can affect your car insurance rate. Some employers check it before hiring you.

Build it early. Pay everything on time. Keep your credit card usage under 30% of your limit. Check your score for free every month. These tiny habits at 20 will save you enormous amounts of money and stress at 30.

5. An Emergency Fund is Not Optional

I used to think emergency funds were for paranoid people. Who needs $1,000 sitting in an account doing nothing when I could spend it? That money could be enjoying life right now instead of collecting dust.

Then my car broke down, and the repair was $800. I didn't have $800. I didn't have $200. I put it on a credit card. That $800 repair turned into $1,100 after interest because I could only pay the minimum for months.

Then two months later, I needed dental work. $400. Back on the credit card. Then my laptop died. Another $350. Credit card again. Within six months, three emergencies that I could have handled with a $1,500 emergency fund had instead put me $2,000 in credit card debt that took me over a year to pay off.

4 Emergencies happen. As a baseline, work toward setting up an emergency fund that covers 3-6 months of basic living expenses. This bank account is often separate from your checking account, used for daily expenses.

I know saving 3 to 6 months of expenses sounds impossible when you can barely make it to payday. So start smaller. 5Build up 3 to 6 months of living expenses for your emergency fund. Sound overwhelming? A starter fund of $500 to $1,000 helps in a pinch. Even $500 sitting in a separate savings account would have saved me from thousands in credit card debt. Start there. Build it up over time. But start.

6. "Treating Yourself" is How Companies Take Your Money

This is going to sound harsh, but I need you to hear it. The phrase "treat yourself" has been weaponized by marketing companies to make you feel like spending money you don't have is an act of self-care. It isn't.

I used to "treat myself" every single Friday. Hard week at work? Treat yourself. Got through a tough Monday? Treat yourself. Feeling sad? Treat yourself. Every negative emotion had a spending solution.

By the end of the month, those "treats" added up to $300 to $500 in completely unnecessary purchases. Clothes I wore once. Meals I forgot about by the next day. Gadgets that ended up in a drawer. None of it made me happier for more than about 20 minutes. All of it made me broke for the rest of the month.

Real self-care is having money in your savings account when something goes wrong. Real self-care is not waking up at 2 am doing panicked math about whether you can make it to payday. That peace of mind is worth more than any "treat yourself" purchase ever could be.

I'm not saying spend money on things you enjoy. I'm saying be honest about whether you're spending because you genuinely want something or because you're trying to medicate an emotion with your credit card.

7. Saying No to Social Plans is Not Failure

16 A big part of your 20s is building relationships and experiences, but that often comes with spending money. It's easy to feel like you have to say yes to every dinner, weekend trip, or concert. I've definitely said yes to things I couldn't really afford at the time, just because I didn't want to be the one sitting it out.

I lived this for years. Every time someone invited me somewhere, I said yes. Dinner out? Yes. Weekend trip? Yes. Concert? Yes. Bar after work? Yes. I was terrified that if I said no, I'd be left out. Forgotten. Replaced.

So I spent money I didn't have to maintain a social life I couldn't afford. And the whole time I was smiling on the outside and panicking on the inside because I knew my bank account was empty and I had no idea how I was going to make it to Friday.

The day I finally told a friend, "I can't afford to go out this week," was one of the hardest and most liberating moments of my twenties. She said, "Totally get it. Want to just come over and watch a movie?" No judgment. No drama. Just understanding.

16 And when I started talking openly with friends about financial goals, I learned that many of them were feeling the same pressure. If you're honest about what you can and can't spend money on, you'll be surprised how often people relate.

Most of your real friends are also struggling. They're just too scared to say it first. Be the one who says it first. You'll be surprised how many people breathe a sigh of relief when you do.

8. Investing is Not Just for Rich People

At 20, I genuinely believed investing was something only wealthy people did. People in suits. People with financial advisors, stock portfolios, and corner offices. Not me. I was just trying to afford groceries.

18 I was under the common misconception that you have to have a lot of money to invest and that you have to have this super mathematical brain filled with innate investing knowledge. Neither one of those things is true. In fact, the younger you start, the better off you'll be.

You can start investing with $5. I'm serious. Five dollars. Some apps let you invest spare change. There are index funds you can buy into with almost nothing. The barrier to entry is essentially zero in 2026.

The issue was never that I couldn't afford to invest. The issue was that I didn't think investing was "for people like me." That belief cost me almost a decade of compound growth that I can never get back. Every year I waited was a year my money wasn't growing. And because of how compound interest works, those early years are the most valuable ones.

If you are in your twenties right now, you have something that no amount of money can buy — time. Use it. Even $25 a month invested now will matter enormously 30 years from now.

9. Debt is Not Normal (Even Though Everyone Has It)

Here's something that messed with my head for years. Everyone around me had debt. Credit card debt. Student loan debt. Car loan debt. It felt so normal that I didn't even question it. Having debt just seemed like part of being an adult. Like taxes and back pain.

But debt is not normal. Debt is expensive. Every dollar you owe someone is a dollar that's costing you money every single day in interest. And every dollar going toward debt payments is a dollar that's not going toward your savings, your investments, your future.

I'm not talking about a mortgage. A home is an asset that generally appreciates over time. I'm talking about consumer debt. Credit cards. Personal loans for things you don't need. Financing a TV, a phone, or a vacation.

When I was 22, I financed a $1,200 laptop because the store offered "easy monthly payments." It felt painless. $50 a month. No big deal. The interest rate was 22%, and by the time I paid it off, I had spent over $1,600 on a laptop that was already outdated. I paid $400 extra for the privilege of not saving up and buying it outright.

Every time you finance something, you are paying a premium to have it now instead of later. That premium goes directly into someone else's pocket. Usually a bank.

10. Your 20s Set the Financial Tone for Your Entire Life

This is the one that hits hardest looking back. 14I often advise people that their 20s reflect the practices that they will build in their 60s, and viewing their salary as a tool rather than just a number is the first step.

The habits you build right now — good or bad — will compound just like interest does. If you build the habit of saving automatically at 22, you won't even think about it at 32. It will just be something you do. If you build the habit of checking your credit score monthly at 23, you'll have a perfect score by 30. If you build the habit of living below your means at 25, lifestyle inflation will never catch you.

But the reverse is also true. If you build the habit of swiping your credit card for everything at 22, that habit will follow you into your 30s and 40s. If you build the habit of ignoring your finances at 23, you'll still be ignoring them at 33 with way more at stake. If you build the habit of spending everything you earn, you'll be 40 with nothing saved and wondering where the time went.

Your twenties are not a practice round. They are the foundation. Everything you build financially for the rest of your life will sit on top of what you do right now.

The Mistakes I Made That Prove All of This

I got my first credit card at 19 and maxed it out within 4 months. I didn't understand that a credit limit is not income. That one mistake took me almost a year to dig out of, and it dropped my credit score by over 100 points.

I said yes to every social event for two straight years, even when I knew I couldn't afford it. I estimate I spent somewhere between $4,000 and $6,000 over those two years on dinners, trips, and nights out that I paid for with money I did not have.

I ignored my retirement account for the first 5 years of my working life because "retirement is so far away." Those 5 years of missed compound growth will cost me tens of thousands of dollars by the time I actually retire. You cannot get time back. Ever.

I kept my savings in my checking account instead of a separate account. Every time something came up — and something always came up — I dipped into it. By the end of every month, my "savings" were back to zero. Moving it to a separate bank was the simplest change that made the biggest difference.

Real Talk

I know this list is a lot. And if you're in your early twenties reading this, it might feel overwhelming. Like you're already behind. Like you've already messed up.

You haven't. Whatever mistakes you've made so far, they are fixable. Every single one of them. The credit score can be rebuilt. The debt can be paid off. The savings account can be started today. You are not too late.

16 You don't need to have every part of your financial life figured out. But the sooner you start building habits like saving a little, tracking your spending, and paying attention to your credit, the easier it becomes to make progress.

Start with one thing from this list. Not all ten. One. The easiest one for you. Maybe it's opening a savings account. Maybe it's checking your credit score for the first time. Maybe it's setting up a $25 automatic transfer. Just one small thing.

That one thing will lead to another. And another. And before you know it, you'll be the person your friends come to for money advice instead of the person who can't afford to split the check.

Do This Before You Close This Page

First. Check your credit score right now for free. You can do this at annualcreditreport.com or through your bank's app. Just look at the number. That is your starting point.

Second. Open a separate savings account at a different bank from your checking account. Any free online savings account with no fees. Move $20 into it right now. That is your emergency fund. It is $20 today, and it will grow.

Third. Write down one financial habit you want to build this month. Just one. Tape it to your bathroom mirror or set it as your phone wallpaper. Look at it every day.

That is 15 minutes of your time. And it is more financial planning than most people in their twenties ever do. You're already winning.

Your Turn

I'm writing this at 28, and I still feel the weight of the mistakes I made at 20, 21, 22. Not because they ruined me. But because they were so avoidable. All I needed was one person to sit me down and have an honest conversation about money. Nobody did.

So this is me doing that for you. Consider this your honest money conversation. No judgment. No shame. Just the stuff I wish someone had told me.

Drop a comment and tell me which of these 10 lessons hit hardest for you. Or tell me the money mistake you made in your twenties that taught you the most. I read every single comment.

Questions People Search About Money in Your 20s

What is the best financial advice for someone in their 20s?

Start saving and investing as early as possible, even if it is a tiny amount. The power of compound interest means that $100 invested at 22 is worth significantly more than $100 invested at 32. Build the habit first. The amount will grow as your income grows.

What should I have saved by 25?

A common benchmark is to have at least three months of basic living expenses saved in an emergency fund by 25. For most people, that is somewhere between $3,000 and $6,000. If you are not there yet, do not panic. Start with $500 and build from there. Any amount is better than zero.

Is it too late to start saving at 25 or 28?

Absolutely not. The best time to start saving was 5 years ago. The second-best time is today. Starting at 25 or 28 still gives you decades of compound growth ahead of you. You are not behind. You are starting.

How do I start investing with no money?

Many investment platforms now allow you to start with as little as $1 to $5. You do not need thousands of dollars to begin. Open a simple investment account, set up a small automatic monthly contribution, and choose a broad market index fund. The key is starting, not the amount.

Why am I always broke in my 20s, even with a decent job?

The most common reason is lifestyle inflation — your spending increases every time your income increases. The second most common reason is invisible spending on small daily purchases that add up to hundreds per month without you realizing it. Track every dollar you spend for 30 days, and you will likely find the answer.

The biggest thing I wish I had done at 20 was start investing. I finally started with just $50 and wrote about exactly how to start investing as a complete beginner. I also wish someone had told me about the 7 money mistakes that cost me thousands.

This is part of the Broke to Basics series on Money Map Today. If you wish someone had told you this stuff earlier, share it with someone who is in their twenties right now. It might save them years of stress.
