Your credit card interest rate doesn’t matter

I'm tired of people bragging about their low credit card interest rate. Here's why I don't care if your credit card interest rate is 5% or 80%.

Listen up: your credit card interest rate doesn’t matter. I’ve gotten some heat for this idea, but I don’t care. I’m tired of people bragging about their low credit card interest rate. Here’s exactly why it’s not important if your credit card interest rate is 5% or 80%.

What is a credit card’s “interest rate” anyway?

A credit card basically gives you a short loan for the month. If you pay it off completely during that monthly period, you don’t pay for the loan–it’s an interest-free loan.

Pretty useful, right? That’s why I’ve described credit cards before as “a delightful gift from heaven”.

But if you don’t pay off the loan in its entirety — let’s say you spend $1,000 on your credit card but can only pay off $500 that month — then you have a balance on your card.

Your credit card balance is what the interest is charged on; typically, it’s somewhere around 20%. In this case, you’d be charged $8.33 that month ($500 balance * 20% interest) / (12 months).

Why I don’t care if my credit card interest rate is 5% or 80%

It’s simple: I never carry a balance on my credit card — and neither should you. When it comes to making purchaes, if can’t pay it off at the end of the month, I don’t buy it.

I’m not going to belabor the point because, if you’re reading this, you clearly care about your money. But you would be shocked how many people I talk to that charge purchases to their credit card without knowing how much they’ll actually pay for it. So let’s take a look…

The danger of credit card minimum payments

Let’s say you have a $10,000 balance on your credit card and you pay the minimum amount, which is around 2.5% every month. How much will it actually cost you? The answer is shocking. Get ready!

If you only paid the minimum on your $10,000 balance, it would take you 452 months (over 8 years!) and cost you over $19,000 in interest alone.

In other words, you’d pay around $30,000 for a $10,000 balance.

That’s if you just pay the minimum monthly payment. How about if you pay the same amount every month so that you pay down the balance faster over time?

Let’s take the same $10,000 balance and pay $250 off every month.

It will cost you over $6,000 in interest and take you 67 months to pay off the balance. Even if you don’t buy another thing in that time!

This is why credit card companies are so incredibly profitable, especially with young people who don’t know any better.

The point is pretty obvious:

  1. Don’t carry a balance (if you do, pay it off as quickly as you can).
  2. Pay the maximum every time.
  3. If you can’t pay off a purchase by the end of the month, don’t buy it.

“But Ramit,” people say, “what about homes and college and cars? How can I pay that off in one month?” Yes, true, those very expensive purchases necessitate some kind of longer-term loan. But not with your credit card.

So when I hear people excited about their introductory interest rate (“It’s 0% for 6 months!!”), I’m not really impressed. As long as you pay your balance in full every month, your credit card interest rate is meaningless.

    All I ever think when I get these offers in the mail is: WHY WOULD YOU EVER CARRY A BALANCE ON YOUR CREDIT CARD!? (Thank you for yelling on my behalf.) I don’t even know the interest rates on any of the credit cards I’ve ever held.

    The only time it is at all relevant is when you play games with a super-low (0%) interest rate on a very high-limit card. Some people with balls and money to back them up use these offers to invest aggressively over 6-12 month windows. Even if you only do something super-low-risk so you can easily guarantee your ability to pay it off, this is the one time a credit card really does give you “free money.”

  2. Rachel Lane

    I admire your discipline and agree with your advice.


    …my cynicism provokes me to say (perhaps controversially) that the fact you are a student at Stanford gives you more flexibility in managing your finances than other students.

    I have recently paid of an outstanding balance of two years and just feel such complete relief. There have been times when I have had to suddenly put large costs on my card – such as car insurance changes, travel costs, suit for graduation interviews etc. Sometimes the money just isn’t there when it has to be!

    You don’t have to have the shopping habits of Karyn Bosnak in order to find yourself short of cash.

  3. Roque Curiel

    You’re correct in saying that interest rates do not matter if you pay off the ballance every month but check your statement on how interst is calculated. It is not calculated on the balance remaining after your payment.

    My name is Roque Curiel, I used to teach personal financial management at the university level and I am the author of the textbook, “Money Well Spent.”

    I admire your mission and I think I understand the point of chossing the title you have for your blog. I teach people to achieve financial independence, which is a different state of mind than rich, altogether. There are rich people going bankrupt everyday. FI is a a condition of enough to meet your needs; sadly, rich is a distorted vision of a certain level of consumption (usually) that some people carry around in their heads.

  4. Ramit

    Roque, you’re right about the interest accruing on each purchase the month after you have a running balance. Thanks for pointing that out.

  5. Jerry Kindall

    Some credit cards use the nefarious two-cycle daily balance, which keeps you paying interest on half of what you’ve paid off for a FULL MONTH after you make your payment. Watch out for this trap!

  6. Vincent Lauria

    Well, I don’t agree with you 100% on not carrying a balance, that’s a lifestyle choice.

    On a side note, this is what I use my 0% CC’s for is this:

    Get one that gives you a year at 0%. Then ‘pay-off’ another CC. When I say pay-off, I mean pay it to another card with no balance. Then have that other card cut you a refund check. Then use that refund check to put it into an investment, like Then make ~$100 month off of interest alone, for doing VERY LITTLE.

    Hi Roque,

    What a small world !, My name is Roque Curiel also. We share many financial credos. I refuse to carry a balance on our two credit cards and actually get 1% cash back on our Golden 1 Visa card.
    I bought your book from but it looks like the printing was not complete, I did not get the seven steps to financial freedom, the book ended abruptly. My wife was surprised when she read the book, she thought that most of the ideas related to my way of thinking, except for the deep quotes. Anyway, we are a family of four with a mortgage of $1506.00 per month and a second (swimming pool) of $467.00 per month. our income is about $105,000 pretax and we have a couple of retirement and colllege funds (Retirement is payed by our employers, college fund is $100.00 per month). We have about $300,000 equity in our house and plan to stay here for quite a while. Any suggestions ????.

    Ah, but if your credit card offers a fixed rate balance transfer that is lower than the interest rate of your current student, business or car loan, and you don’t use that card for anything else, it can be quite economically smart to carry the balance there rather than with the higher rate lender. For example, we took out a small business loan which I transferred to a credit card at 2.9% fixed. I don’t use the card at all. Just make the biggest payments we can every month. We did the same thing with our car loan and the balance on my student loan. Because you can’t beat a 2.9% fixed APR.

  9. Marnell Bookins

    Run these numbers, pay 50% of a credit card balance each month for 6 months or less, calculate the actual real rate of interest.

  10. prlinkbiz

    I carry a 30% balance on my cc. This is a strategy I am using for building credit. It is a low limit card, that I use only for already budgeted monthly expenses. I do not care what the interest rate is, because the credit it is building for me will allow me to make many times that amount. Credit is like a muscle- use it or lose it. Use it wisely, and it can be an invaluable tool to financial freedom.

    • Nelson

      Actually you don’t need to carry a credit to build your credit. You are wrong about that. The other guy commenting, Roque. I can’t believe you wrote a book on financial freedom and you can’t even spell balance. Go figure…

  11. Ramit Sethi

    Wait, why 30%? Have you heard of your debt-to-credit ratio? Lower is better for your credit score.

  12. john

    prlinkbiz, you’re nuts! i started out with a low credit limit on my first card (I also got it to establish credit), and within 6 months of paying the whole thing off every time, the company raised the credit limit from 500 to 2000. I’m sure they would raise it more if I needed it.

  13. Jonathan van Clute

    Forgive me, but in my opinion this post and the sentiments expressed in it, are dead wrong.

    One thing is absolutely right however – your credit card interest rates DON’T matter, but not at all for the reasons expressed.

    They don’t matter because if you use it like the very powerful tool it is, your credit card can make you lots and lots of money.

    If you borrow say $3000 on a credit card at 2.9%, and use that money as the down payment on a rental property that costs $30,000 and pays you $400 per month in rent, you have effectively just given yourself a 2.9% second mortage – something simply not possible ordinarily. This means you will have gotten into a “no money down” deal, that puts additional cash in your pocket every month, net of expenses, management, everything.

    Think I’m making those number up? Think again. I have 4 such properties right now with more coming regularly.

    Paying off your credit cards every month being good for your credit is ALSO a total myth. Anyone who has actually put this into PRACTICE knows that the best way to increase your overall credit picture as far as credit cards goes, is to use them, and pay them off over 3 months or so.

    How do I know this? Well, I’m no guru… but I would say I’m an “expert” based on experience, not based on what I write on the internet. I paid off a Chapter 13 bankruptcy in January of 2006 (this year – just 9 months ago!) As of a month ago, I had a 718 FICO score. How on earth do I have a 718 score fresh out of bankruptcy? Working the system. Using the rules of the system to my advantage. I have one credit card only, and it had a 700 limit. By using it and paying it down over a couple months at a time, I now have a $1500 limit on that card and could probably get other cards if I wanted to, which at this point I don’t (by the way, the best number of credit cards to have is 3).

    My partner and I are professional, full time real estate investors. We don’t do “fix & flip” or speculate in crazy markets like our home in Northern California. We buy RIGHT, and we make money – consistently. We make returns of 1000 to 3000% (yes, THREE THOUSAND PERCENT) on our cash, when we even use our own cash. This is NORMAL. We also bought a house in the San Francisco Bay Area with 20% equity in it when we walked in the door, then we cleaned it up a bit and added another 100k to the value. But there are no shortage of people who tells us that we can’t do what we do. If only they new or were willing to listen…

    So in closing… please do not believe everything you read ESPECIALLY on the internet. When it comes to your financial future, you need to do your own homework and get as many different points of view on the subject as possible, and you need to be in many different investment vehicles in order to find the one(s) that suit you best. Personally, I like to make infinite% returns, which is quite easy when you learn how to produce positive cash flow without using any of your own money.

    Oh also I would say that a very valuable book for us has been the eBook available at – we put into practice what he writes about and saw immediate results to our credit scores, limits, and overall comfort with utilizing credit to its fullest extent.

    Happy investing everyone!

    I have a credit card with 18.99%. I don’t mind too much as I get cash back and I pay the balance in full. Thanks for posting an article that has common sense.

  15. Basiex

    The 3% transaction fee wipes out any profit one can make on a low interest card.

  16. Olivia

    Well, you should know if you have great self control it is also wonderful to use balance transfer offers for car loans. I have really good credit and do get the “great low rates on cards” so I am one of those that also gets the 18 month 0% offers or 1.9% offers for 12mths. Most recently I got an offer of 0% for 12 months. In the past 10 years I have bought two cars totaling $45,000 and used balance transfer offers. I have paid less than $400 to 500 to do this, total for these cars including interest and transfer fees. This is a steal. No, I did not have much saved up either. Anyway, think about the interest on a $20,000.00 car @ 7% for 1 Year. That is around $1,400 for the 1st year alone. YUCK! SO…Think about it. The low rate is definitely important. The difference is that you don’t need the flexibility of carrying a balance past one month, but some people do. Personally, I only use them for car loans because I do better than saving up or financing through the bank or credit union. Sounds like you need to just cut your credit cards up and use a debit card. I am a little confused as to why you are giving this kind of credit card advice though. Afterall, all you need for an emergency is a debit card, anyone can run it as a credit. I never give out my pin number and always run it as a credit, everyone knows that. Check with your bank. That way when you tell people interest rates don’t matter it will be because you don’t have one, instead of the fact that someone elses may be lower than yours. It just sounds like to me you are fed up with a few braggarts that told you your rate was too high. Can’t really blame you for that either though. They can be pretty annoying. Met one this past weekend. GOD BLESS!!!!

    what a junk article, do you think that you have conveyed something Great.if you think so, then there is something wrong with your thinking process itself. Inwhich way the article and the topic heading co-relating .

  18. Rossie

    I am a little confuse on how you came up with those numbers! If you have a $10,000 dollars debt and only pay $250.00 it will take you 8 years to pay off what? First off you definitively left out the interest rate which is what the banks used to get the daily periodic rate. I understand you did this to prove your point, but in my opinion it is not a very educated one. I calculated how long it will take me to pay a 10,000 debt on a credit card with my current interest rate and that came out to be:

    Months to pay off debt:53 or 4.4 years
    Total interest you will pay:$3,174.91
    Total to pay back:$13,174.91

    That being said if you do pay the minimum payments that your bank ask which is about 2%, then yes it will take you a lot years to pay off the debt and you might end up paying twice as much all depending on the interest rate! Just take a close look to your card statement and they will definitively tell you how much your minimum payment is and if you choose to pay just that how long it will take you to pay it off and how much money you will end up paying and don’t believe all the banana people post!!!!!

    My name is Elizabeth forbes from united states. I want to thank Mr

    Johnson who helped me to get a loan. For the past three months, I have

    been searching for a loan to settle my debts, everyone I met scammed

    and took my money until I met Mr Johnson Snowberger. He was able to

    give me a loan of $15,000US Dollars. He can also help you. He has also

    helped some other colleagues of mine. If you need any financial help,

    kindly contact his company through email: I believe he can help you. Contact him

    to get help just as he helped me. He doesn’t know that I am doing this

    this by spreading his goodwill towards me but I feel I should share this
