How will going from 75% Credit Utilization to 0% Credit Utilization affect my credit score?
I wrote an article about FICO scoring which shows that 30% of your score is based on utilization or amount owed. I can't say exactly how much your score will rise, or how long it will take, but your score will improve dramatically from what you propose.    This chart is from Credit Karma, and it shows how zero utilization is actually bad when it comes to your score. I wrote an article on my blog titled Too Little Debt in which I discuss further. Under 20% is ideal, just not zero. "You really don't know how credit scoring works. Let's think about the purpose of a credit score: to assess whether you're a high default risk. A lender wants to know, in this order: Utilization factors into the solvency assessment. If you are at 100% utilization of your unsecured credit, you're insolvent -- you can't pay your bills. If you are at 0%, you're as solvent as you can be. Most people who use credit cards are somewhere in the middle. When a bank underwrites a large loan like a mortgage or car loan, they use your credit score an application information like income and employment history to figure out what kind of loan you qualify for. Credit cards are called ""revolving"" accounts for a reason -- you're supposed to use them to buy crap and pay your bill in full at the end of the month.  My advice to you:"
See the accepted answer for this question.  What effect will credit card churning for frequent flyer miles have on my credit score? This does not directly answer 'how often...' that you asked, but it states that the answerer opens 5-15 accounts per year.  So the answer to your question is, as often as you want, as long as you manage your account ages. The reason for this is that there are two factors in opening a new account that affect your credit card score.  One is average age of accounts. The other is credit inquiries.  That answerer, with FICO in high 700s, sees about a 5% swing based on new cards and closing old ones. You'll have to manage average age of accounts.  I assume this is done by keeping some older ones open to prop up the average, and by judiciously closing the churn accounts. Finally, if you choose to engage in churning, and you intend to apply for a large loan and want a good credit score, simply pause the account open/close part of the churn a couple of months ahead of time.  Your score should recover from the temporary hits of the inquiries.   The churning communities really do have how to guides which discuss the details of this.  Key phrase: credit card churning. Paying weekly to be able to have maneuver room under your credit limit is a way to handle low credit limits. Doing it to boost your credit score when you have no immediate need for a loan is wasting energy.  A few months in advance of buying a car or house, you can start to worry about your utilization rate. When you apply for the loan they will pull your credit file, and that will lock in your utilization rates. Then make sure that you pay the balance quickly, and if you need to make a big purchase pay the bill before the account closes for the month. Keep in mind that if you pay the balance every month the highest utilization rate will occur the day the payment is due. This is because it not only has all the purchases from the previous bill, but all the purchases you have made since that bill closed. For example if you have a credit limit of 10K and you spend 2K a month on the credit card, on the day the payment is due it is not unusual to see the total owed to be above 3K. If they pulled your file on that day, your utilization rate would appear to be above 30%. Also, unless I missed it and someone already mentioned it, do keep in mind the impact of these credit cards balances on your credit score. Over roughly 75% usage on a given credit account reflects badly on your score and has a pretty large impact on how your worthiness is calculated. It gives the impression that you are a person that lives month to month on cards, etc. If you could get both cards down to reasonable balances to where you could begin paying on them regularly and work them down over time, that will not only look incredible for your credit report but also immediately begin making your credit worthiness begin to raise due to the fact that you will not have accounts that (I'm assuming here) are at very high usage (over 75% of your total limit.) If you have to get one card knocked out just to get breathing room, and you're boxed in here -- or honestly even if the mental stress is causing you incredible hardship day to day, then I suppose blow one card out of the water, reassess and start getting to work on that second card. I hope this helped, I'm no expert, but I have had every kind of luck with credit cards and accounts you could think of, so I can only give my experience from the rubber-meets-the-road perspective. Good luck! Your credit score is really bad, and it's highly unlikely anyone will be willing to give you a mortgage, especially if you still have bad debt showing up on your credit report. What would help? Well, clearing off any bad debt would be a good place to start. Ideally, you want to get your credit rating up above 680, though that may be optimistic here. Note, though, that bad debt falls off your credit report after a while. Exactly how long depends on your province. Note that making partial payment, or even just acknowledging the debt, will reset the 'timer', however. I mention this, though, because you mention some of your debt is from 5 or 6 years ago. It may be just about to fall off. It would also help if you can show that your credit is so bad because of mistakes from a number of years ago, but you've been making payments and staying on top of all debts for the past few years, if that's the case. Also, it would help if you had a reasonable downpayment. 20% minimum, but you'll be a lower credit risk if you are able to put down 50 - 75%. You could also consider having someone with good credit co-sign the mortgage. Note that most people will not be willing to do this, as they take on substantial financial risk. All that said, there are some institutions which specialise in dealing with no credit or bad credit customers. You pay more fees and will pay a vastly higher interest rate, but this may be a good option for you. Check out mortgage brokers specialising in high-risk clients. You can also consider a rent-to-own, but almost all the advice I've ever seen say to avoid these if you can. One late payment and you may lose all the equity you think you've been building up. Note that things may be different if you are moving from the U.S. to Canada, and have no credit history in Canada. In that case, you may have no credit rather than bad credit. Most banks still won't offer you a mortgage in this case, but some lenders do target recent immigrants. Don't rule out renting. For many people, regardless of their credit rating, renting is a better option. The monthly payments may be lower, you don't need a downpayment, you don't have to pay realtor and legal fees (and pay again if you need to move). A couple of sites provide more information on how your credit rating affects your possibility of getting a mortgage, and how to get mortgages with bad credit: http://mortgages.ca/credit-score-needed-mortgage-canada/ and http://mortgages.ca/mortgage-solutions/new-to-canada-financing/, along with  http://www.ratehub.ca/mortgage-blog/2013/11/how-to-get-a-mortgage-with-bad-credit/ "There are two factors in your credit score that may be affected. The first is payment history. Lenders like to see that you pay your bills, which is the most straightforward part of credit scores IMO. If you've actually been paying your bills on time, though, then this should still be fine. The second factor is the average age of your open accounts. Longer is considered better here because it means you have a history of paying your bills, and you aren't applying for a bunch of credit recently (in which case you may be taking on too much and will have difficulties paying them). If this card is closed, then it will no longer count for this calculation. If you don't have any other open credit accounts, then that means as soon as you open another one, your average age will be one day, and it will take a long time to get it to ""good"" levels; if you have other matured accounts, then those will balance out any new accounts so you don't get hit as much. Incidentally, this is one of the reasons why it's good to get cards without yearly fees, because you can keep them open for a long time even if you switch to using a different card primarily." How will going from 75% Credit Utilization to 0% Credit Utilization affect my credit score? might answer your question if US based.  In the US, what counts is what shows on the bill. I've run $20K through a card with a $10K limit, but still ended the month under $2K by making extra payments. As long as you stay ahead of the limit by making mid-cycle payments, I see no issue with this strategy. If you keep running $30K/mo through a card with a $10K limit, the bank will eventually catch this and raise your limit as you will have proven you are more credit worthy. I do this all the time, my credit rating over time plotted on a graph looks like saw blades going upward on a slope I use a credit alert service to get my credit reports quarterly, and I know when the credit agencies update their files (every three months), so I never have a high balance at those particular times Basically, I use the negative hard pulls to propel my credit score upwards with a the consequentially lowered credit utilization ratio, and the credit history. So here is how it works for me, but I am not an impulse buyer and I wouldn't recommend it for most people as I have seen spending habits: Month 1: charge cards, pay minimum balance (raises score multiple points) Month 2: PAY OFF ALL CREDIT CARDS, massive deleveraging using actual money I already have (raises score multiple points) Month 3: get credit report showing low balance, charge cards, pay minimum balance ask for extensions of credit, AND followup on new credit line offers (lowers score several points per credit inquiry) Month 4: charge cards, pay minimum balance, discretionally approving hard pulls - always have room for one or two random hard pulls, such as for a new cell phone contract, or renting a car, or employment, etc Month 5: PAY OFF CREDIT CARDS using actual money you have. (the trick is to NEVER really go above a 15% credit utilization ratio, and to never overleverage. Tricky because very quickly you will get enough credit to go bankrupt) Month 6: get credit report showing low balances, a slight dip in score from last quarter, but still high continue. After doing some investigating, my employers contract with the credit card company has a clause that basically specifies that despite my name being on the credit card, and bills being sent to me, all liability is on the company. Additionally, the employer reserves the right to garnish wages in the event of a balance on the card. So it looks like it won't affect my credit score. I appreciate all of the advice.
