Should I always pay my credit at the last day possible to maximize my savings interest?
If you have the ability to pay online with a guaranteed date for the transaction, go for it. My bank will let me pay a bill on the exact date i choose. When using the mail, of course, this introduces a level of risk.  I asked about rates as the US currently has a near zero short term rate. At 3.6%, $10,000, this is $30/month or $1/day you save by delaying. Not huge, but better in your pocket than the bank's. "To avoid nitpicks, i state up front that this answer is applicable to the US; Europeans, Asians, Canadians, etc may well have quite different systems and rules. You have nothing to worry about if you pay off your credit-card statement  in full on the day it is due in timely fashion. On the other hand, if you routinely carry a balance from month to month or have taken out cash advances, then making whatever payment you want to make that month ASAP will save you more in finance charges than you could ever earn on the money in your savings account. But, if you pay off each month's balance in full, then read the fine print about when the payment is due very carefully: it might say that payments received before 5 pm will be posted the same day, or it might say before 3 pm, or before 7 pm EST, or noon PST, etc etc etc. As JoeTaxpayer says, if you can pay on-line with a guaranteed day for the transaction (and you do it before any deadline imposed by the credit-card company), you are fine.  My bank allows me to write ""electronic"" checks on its website, but a paper check is mailed to the credit-card company. The bank claims that if I specify the due date, they will mail the check enough in advance that the credit-card company will get it by the due date, but do you really trust the USPS to deliver your check by noon, or whatever? Besides the bank will put a hold on that money the day that check is cut. (I haven't bothered to check if the money being held still earns interest or not).  In any case, the bank disclaims all responsibility for the after-effects (late payment fees, finance charges on all purchases, etc) if that paper check is not received on time and so your credit-card account goes to ""late payment"" status.  Oh, and my bank also wants a monthly fee for its BillPay service (any number  of such ""electronic"" checks allowed each month). The BillPay service does include payment electronically to local merchants and utilities that have accounts at the bank and have signed up to receive payments electronically. All my credit-card companies allow me to use their website to authorize them to collect the payment that I specify from my bank account(s). I can choose the day, the amount, and which of my bank accounts they will collect the money from, but I must do this every month. Very conveniently, they show a calendar for choosing the date with the due date marked prominently, and as mhoran_psprep's comment points out, the payment can be scheduled well in advance of the date that the payment will actually be made, that is, I don't need to worry about being without Internet access because of travel and thus being unable to login to the credit-card website to make the payment on  the date it is due. I can also sign up for AutoPay which takes afixed amount/minimum payment due/payment in full (whatever I choose)  on the date due, and this will happen month after month after month  with no further action necessary on my part.  With either choice,  it is up to the card company to collect money from my account on the day specified, and if they mess up, they cannot charge late payment fees or finance charge on new purchases etc.  Also, unlike  my bank, there are no fees for this service. It is also worth noting that many people do not like the idea of the credit-card company withdrawing money from their bank account, and so this option is not to everyone's taste." Mostly ditto to Dillip Sarwate. Let me just add: I don't know how you're making your payments, whether through the biller's web site, your bank's web site, by mail, in person, etc. But whatever the mechanism, if there is a chance that waiting until the due date to pay may mean that you will miss the due date: don't. The cost of a late payment charge is likely to far exceed any interest you would collect on your savings. Bear in mind that we are talking pennies here. I don't know how much the monthly bills that we are discussing here come to. Say it's $3,000. I think that would be a lot for most people. You say you're getting 3.6% on your savings. So if, on the average, you pay a bill 2 weeks later than you might have, you're getting an extra 2 / 52 x 3.6% x $3,000 in interest, or $4 per month. I think the last time I paid a late fee on a credit card it was $35, so if you make one mistake every 8 months and end up getting a late fee it will outweigh any savings.  Personally, I pay most of my bills through either my bank's web site or the biller's web site. I schedule all payments when I get a paycheck, and I generally try to schedule them for 1 week before the due date, so there's plenty of breathing room.
Since this post was migrated from Parenting, my reply was in the context where it appeared to be misrepresenting facts to make a point. I've edited it to be more concise to my main point. In my opinion, the best way to save for your childs future is to get rid of as much of your own debt as possible. Starting today. For the average American, a car is 6-10%. Most people have at least a couple credit cards, ranging from 10-25% (no crap). College loans can be all over the map (5-15%) as can be signature (8-15%) or secured bank loans (4-8%). Try to stop living within your credit and live within your means. Yeah it will suck to not go to movies or shop for cute things at Kohl's, but only today.  First, incur no more debt. Then, the easiest way I found to pay things off is to use your tax returns and reduce your cable service (both potentially $Ks per year) to pay off a big debt like a car or student loan. You just gave yourself an immediate raise of whatever your payment is. If you think long term (we're talking about long-term savings for a childs college) there are things you can do to pay off debt and save money without having to take up a 2nd job... but you have to think in terms of years, not months. Is this kind of thing pie in the sky? Yes and no, but it takes a plan and diligence. For example, we have no TV service (internet only service redirected an additional $100/mo to the wifes lone credit card) and we used '12 taxes to pay off the last 4k on the car. We did the same thing on our van last year. It takes willpower to not cheat, but that's only really necessary for the first year-ish... well before that point you'll be used to the Atkins Diet on your wallet and will have no desire to cheat. It doesn't really hurt your quality of life (do you really NEED 5 HBO channels?) and it sets everyone up for success down the line. The moral of the story is that by paying down your debt today, you're taking steps to reduce long haul expenditures. A stable household economy is a tremendous foundation for raising children and can set you up to be more able to deal with the costs of higher ed. You need to pay off the entire balance of 7450 as soon as possible. This should be your primary financial goal at this point above anything else. A basic structure that you can follow is this: Is the £1500 balance with the 39.9% interest rate the obvious starting point here? Yes, that is fine. But all the cards and overdraft debts need to be treated with the same urgency! What are the prospects for improving my credit score in say the next 6-12 months enough to get a 0% balance transfer or loan for consolidation? This should not be a primary concern of yours if you want to move on with your financial life. Debt consolidation will not help you achieve the goals you have described (home ownership, financial stability). If you follow the advice here, by the time you get to the point of being eligible, you may not see enough savings in interest to make it worth the hassle. Focus on the hard stuff and pay off the balances. Is that realistic, or am I looking at a longer term struggle? You are looking at a significant struggle. If it was easy you would not be asking this question! The length of time will be determined by your choices: how aggressively you will cut your lifestyle, take on extra jobs, and place additional payments on your debt.  By being that extreme, you will actually start to see progress, which will be encouraging. If you go in half-committed, your progress will show as much and it will be demotivating. Much of your success will hinge on your mental and emotional toughness to push through the hard work of delaying pleasure and paying off these balances. That is just my personal experience, so you can take it or leave it. :) The credit score will take care of itself if you follow this method, so don't worry about it. Good Luck! "The can and the should have been discussed in other answers and comments,  and so I will discuss the how.  As others have noted, it is important to make sure that the additional money goes to reducing principal and not towards  prepayment of interest.  Unfortunately, very few bank tellers understand how mortgages work and very few bank officers - even loan officers - understand how mortgages work too. Thus a statement that you want the extra money to go towards principal will likely be met with a blank look. Furthermore, what they do with the money and how it is entered on the bank books that afternoon when the transactions are recorded may have no resemblance to what was discussed and agreed to earlier in the day.  Based on my personal experiences and  many arguments with banks about how they handled my prepayments and how interest was computed, I would  recommend the following (which is easier now that automated payments are possible for the standard monthly payment and additional payments are possible via electronic funds transfer). Make sure that automated payments are made on the day that the payment is due, not at the end of the ten-day grace period that banks love to grant you for making the monthly payment. Yes, there is no penalty for late payment as long as you pay before the end of the grace period, but interest continues to be charged and so more of each graciously delayed payment goes to interest  and less towards principal. Make the additional payment on the same day as the standard monthly mortgage payment is made. This ensures that at worst just one day's interest is owing when the additional payment is made. Also, payment in the middle of the monthly cycle is an almost sure way of getting ripped off on the interest because the bank's computers will post the payment in the manner most favorable to them, and usually contrary to the terms of your mortgage.  I have  complained to banks about mishandled mid-month payments and won every time, and on many occasions the bank officer would grudgingly say ""We have always done it this way and nobody  ever complained till you did today."" I doubt very much if the bank's programs got changed as a result of my complaints. If you are not sure how mortgages work and how interest  is calculated or don't have the time or inclination to go hassle with the bank each time but do prefer not to get ripped off, make the payment as described: on the dot and at the same time as the regularly scheduled monthly payment. The amortization schedule that the bank should have given you shows how much the principal amount is after the monthly  payment is made on each due date.  Assuming that you have  not been taking advantage of the grace periods and so the schedule is correct, make an additional payment not of a round sum but an exact amount (down to the last penny) that will jump you from principal owing after today's regular payment to principal owing after the regular payment N months from today. Here of course you choose N based on how much extra money you were planning on paying towards your mortgage.  By making the extra payment, you will effectively have cut the length of  the mortgage by n months and the same amortization schedule will apply over the shorter period.  Since very little of the principal is repaid in the early life of the mortgage, an additional principal-only payment can reduce the length of the mortgage by years. Paying a specific amount that matches the amortization schedule also helps if you ever need to hassle with the bank. It is their print-out you are arguing from, and not trying to explain to a clueless bank officer how the bank did not compute interest  correctly after you paid $1500.00 extra at beginning of last month." One thing you may want to consider if your budget is tight....do your own Escrow.  You have to be disciplined, but I don't see that as a problem for you.  Nice job on no car payment or student loans! The banks almost always screw up escrow, and you can keep your monthly savings payment exactly what they need to be.  Dump 610 in a savings account every month and you should be golden.   Here in Orange County, Florida taxes are due in April, you can get a discount of 1%/month if you pay early.  November is the first time you can pay it.  When you run your own escrow, as I do, I can pay when I want (at the end of November) and maximize my discount.  Now your situation may differ, but probably 110% (not based upon research) of escrow accounts are goofed up. If you pay it off before the cycle closes it will look like you have 100% available credit.   So if you credit card statement closes on the 7th pay it off on the 6th in full don't pay it when its due 2/3 weeks later. Then after three months of doing that your credit score will go up based on the fact that your debt ratio is so low.  That ratio is 30% of your credit score.  It will help quite alot. "There are two issues here: arithmetic and psychology. Scenario 1: You are presently paying an extra $500 per month on your student loan, above the minimum payments. Your credit card company offers a $4000 cash advance at 0% for 8 months. So you take the cash advance, pay it toward the student loan, and then instead of paying the extra $500 per month toward the student loan you use that $500 for 8 months to repay the cash advance. Net result: You pay 0% interest on the loan, and save roughly 8 months times $4000 times the interest on the student loan divided by two. (I say ""divided by two"" because it's not the difference between $4000 and zero, but between $4000 and the $500 you would have been paying off each month.) Clearly you are better off. If you are NOT presently paying an extra $500 on the student loan -- or even if you are but it is a struggle to come up with the money -- then the question becomes, can you reasonably expect to be able to pay off the credit card before the grace period runs out? Interest rates on credit cards are normally much higher than interest rates on student loans. If you get the cash advance and then can't repay it, after 8 months you are paying a very steep interest rate, and anything you saved on the student loan will quickly be lost. What I mean by ""psychological"" is that you have to have the discipline to really repay the credit card within the grace period. If you're not very confidant that you can do that, this plan could go bad very quickly. Personally, I've thought about doing things like this many times -- cash advances against credit cards, home equity loans, etc, all give low-interest money that could be used to pay off a higher-interest debt. But it's easy to get into trouble doing things like this. It's easy to say to yourself, Well, I don't need to put ALL the money toward that other debt, I could keep a thousand or so to buy that big screen TV I really need. Or to fail to pay back the low-interest loan on schedule because other things keep coming up that you spend your money on instead, whether frivolous luxuries or true emergencies. And there's always the possibility that something will happen to mess up your finances, from a big car repair bill to losing your job. You don't want to paint yourself into a corner. Finally, maxing out your credit cards hurts your credit rating. The formulas are secret, but I understand that if you use more than half your available credit, that's a minus. How much it hurts you depends on lots of factors." If you have the money and the determination to pay off all the cards in six months, then the order will make little difference to your credit score, and to your finances.  If you had less money available (say you could pay off $500 a month in total), then it would be good for financial reasons to pay off the credit card with the highest interest rate first, so you pay less interest. It would be good for psychological reasons to pay the card with the smallest amount first (so you feel successful quickly, and some people need that feeling of success to continue paying off, just psychological). And if these things contradict each other, figure out what is more important.  And whatever you do, paying back your debt is better than not paying it back. So if you can't make up your mind, then you pay #1, then #2, then #3, then #4, then #5. "One key point that other answers haven't covered is that many credit cards have a provision where if you pay it off every month, you get a grace period on the interest.  Interest doesn't accrue at all unless you rollover a non-zero balance.  But if you do, you pay interest on the average balance, not the rolled-over balance, for the entire month. You have to ask yourself what you are trying to accomplish with your credit history? Are you trying to maximize your ""buying power"" (really, leverage)?  Or are you trying to make sure that you get the best terms on a moderately sized loan (house mortgage, car note)? As JohnFx and losthorse already noted, it's in the banker's best interest to maximize the profit they make off of you.  Of course, that is not in your best interest. Keeping a credit card balance from month to month definitely feeds the greedy nature of the financing beast.  And makes them willing to take more risks, because the returns are also higher.  But those returns cost you. If you are planning to get sensible loans in the future, that you can comfortably afford, you won't need a maxed credit score.  You won't get the largest loan amounts, but because you are doing the sensible thing and making a large down payment, the risk is also very low and you'll find lenders willing to give you a low interest rate.  Because even though the reward is lower than the compulsive purchaser who pays an order of magnitude more in financing fees, the return/risk ratio is still very favorable to the bank. Don't play the game that maximizes their return.  That happens when you have a loan of maximum size, high interest rate, and struggle to make payments, end up missing a couple and paying late fees, or request forbearance which compounds the interest. Play to minimize risk."
