If I get a bill (e.g. for internet service), is that a debt I owe? If no, what are the practical difference between a bill and a debt?
From accounting perspective, an unpaid bill for internet services, according to the Accruals Concept, is recorded as a liability under 'Current Liabilities' section of the Balance Sheet. Also as an expense on the Income Statement.  So to answer your question it is both: a debt and an expense, however this is only the case at the end of the period. If you manage to pay it before the financial period ends this is simply an expense that is financed by cash or other liquid Asset on the Balance Sheet such as prepayment for example. For private persons you are generally given some time to pay the bill so it is technically a debt (Internet Provider would list you as a debtor on their accounts), but this is not something to worry about unless you are not considering to pay this bill. In which case your account may be sold as part of a factoring and you will then have a debt affecting your credit rating. A debt is created when the service is rendered or the goods are sold to you.  The bill is simply a way of recording the debt and alerting you to it.
"Tax is often calculated per item.  Especially in the days of the internet, some items are taxable and some aren't, depending on the item and your nexus.  I would recommend calculating and storing tax with each item, to account for these subtle differences. EDIT: Not sure why this was downvoted, if you don't believe me, you can always check with Amazon: http://www.amazon.com/gp/help/customer/display.html/ref=hp_468512_calculated?nodeId=468512#calculated I think they know what they're talking about. FINAL UPDATE: Now, if someone goes to your site, and buys something from your business (in California) and the shipping address for the product is Nevada, then taxes do not have to be collected.  If they have a billing address in California, and a shipping address in Nevada, and the goods are shipping to Nevada, you do not have to declare tax. If you have a mixture of tangible (computer, mouse, keyboard) and intangible assets (warranty) in a cart, and the shipping address is in California, you charge tax on the tangible assets, but NOT on the intangible assets. Yes, you can charge tax on the whole order.  Yes for most businesses that's ""Good enough"", but I'm not trying to provide the ""good enough"" solution, I'm simply telling you how very large businesses run and operate.  As I've mentioned, I've done several tax integrations using software called Sabrix (Google if you've not heard of it), and have done those integrations for companies like the BBC and Corbis (owned and operated by Bill Gates). Take it or leave it, but the correct way to charge taxes, especially given the complex tax laws of the US and internationally, is to charge per item.  If you just need the ""good enough"" approach, feel free to calculate it by total. Some additional reading: http://en.wikipedia.org/wiki/Taxation_of_Digital_Goods Another possible federal limitation on Internet taxation is the United States Supreme Court case, Quill Corp. v. North Dakota, 504 U.S. 298 (1992),[6] which held that under the dormant commerce clause, goods purchased through mail order cannot be subject to a state’s sales tax unless the vendor has a substantial nexus with the state levying the tax.  In 1997, the federal government decided to limit taxation of Internet activity for a period of time. The Internet Tax Freedom Act (ITFA) prohibits taxes on Internet access, which is defined as a service that allows users access to content, information, email or other services offered over the Internet and may include access to proprietary content, information, and other services as part of a package offered to customers. The Act has exceptions for taxes levied before the statute was written and for sales taxes on online purchases of physical goods." "One can generalize on Traditional vs Roth flavors of accounts, I suggest Roth for 15% money and going pretax to avoid 25% tax.  If the student loan is much over 4%, it may make sense to put it right after emergency fund.  For emergency fund priority - I'm assuming EF really requires 2 phases, the $2500 broken transmission/root canal bill, and the lose your job, or need a new roof level bills. I'm in favor of doing what let's you sleep well. I'm also quick to point out that if you owe $2500 at 18%, yet have $2500 in your emergency fund, you're really throwing away $450 in interest each year. There's an ongoing debate of ""credit card as emergency fund."" No, I don't claim that your cards should be considered an emergency fund, per se, but I would prioritize knocking off the 18% debt as a high priority. Once that crazy interest debt is gone, fund the ER, and find a balance for savings and the next level ER, the 6-9mo of expenses one. One can choose to fund a Roth IRA, but keep the asset out of retirement calculations. It's simply an emergency account returning tax free interest, and if never used, it eventually is retirement money. A Roth permits withdrawal of deposited funds with no tax or penalty, just tracking it each year. This actually rubs some people the wrong way as it sounds like tapping your retirement account for emergencies. For my purpose, it's a tax free emergency fund. Not retirement, unless and until you are saving so much in the 401(k) you need more tax favored retirement money. I wrote an article some time ago, the Roth Emergency Fund which went into a bit more detail.  Last - keep in mind, this is my opinion. I can intelligently argue my case, but at some point, it's up to the individual to do what feels right. Paying 18% debt off a bit slower, say 4 years instead of 3, in favor of funding the matched 401(k), to me, you run the numbers, watch the 401(k) balance grow by 2X your pretax deposits, and see that in year 3, your retirement account is jump-started and far, far more than your remaining 18% cards. Those who feel the opposite and wish to be debt free first are going to do what they want. And the truth is, if this lets you sleep better at night, I'm in favor of it." "To address the issue in the title of your question: Many expenses strike at what for all practical purposes are random intervals. Roof starts leaking, car needs repair, etc, don't have a fixed cost every month. Medical expenses can certainly be more extreme than many other expenses, but their nature is the same. And so the way to budget for them is the same: You figure out what your average expenses are over a long period of time. Then you start putting away a little more than this amount every month. Keep putting away until you have a reserve larger than any expense you are likely to get hit with all at once.  I have no idea what your particular expenses are, so let me use myself for an example. My medical bills last year were unusually large: about $6,000. I have lousy insurance and a couple of chronic conditions, so my bills are usually maybe $1,000 to $2,000 per year. So I plan on about $150 per month for medical bills. Most insurance policies have an ""out of pocket maximum"". This should be the most you'd ever have to lay out in a year. Mine is $13,000. (I told  you my insurance sucks.) So I have an account that I have now built up to $13,000. Worst case, I wipe out that account. In any case, if my bills are that large, the doctors or hospital will normally agree to a payment plan. (I still owe a few hundred on my bills from last year and the hospital is letting me pay it off at $120 per month.) Your question brings up a lot of issues about difficulties of working with insurance and the U.S. medical system in general. I'm not sure if your intent was to get advice on the rest of it all. Simple -- not pleasant, but simple -- answer: If you're insurance is provided by your employer, you're pretty much stuck with the policy that the employer negotiates. I don't know how much you're contributing to premiums, usually the company pays the bulk of it. You could investigate getting a policy on your own, but odds are that any policy you could get for what you're contributing now would be way worse than what you can get through the company. You could always investigate, but I doubt you'll do better. You can talk to HR. If it's a big company, they may have some muscle with the insurance company and could help you out. Failing that, it becomes a political question of how the laws affecting medical care and insurance in the U.S. are set up, and while I have many ideas for how it could be improved, sadly I'm not in a position to do much about it, and I doubt you are either. Unless you have the resources to run for president." "Trying to figure out how much money you have available each day sounds like you're making this more complicated than it needs to be. Unless you're extremely tight and you're trying to squeeze by day by day, asking ""do I have enough cash to buy food for today?"" and so on, you're doing too much work. Here's what I do. I make a list of all my bills. Some are a fixed amount every month, like the mortgage and insurance premiums. Others are variable, like electric and heating bills, but still pretty predictable.  Most bills are monthly, but I have a few that come less frequently, like water bills in my area come every 3 months and I have to pay property taxes twice a year. For these you have to calculate how much they cost each month. Like for the water bill, it's once every 3 months so I divide a typical bill by 3. Always round up or estimate a little high to be safe. Groceries are a little tricky because I don't buy groceries on any regular schedule, and sometimes I buy a whole bunch at once and other times just a few things. When groceries were a bigger share of my income, I kept track of what I spent for a couple of months to figure out an average per month. (Today I'm a little richer and I just think of groceries as coming from my spending money.) I allocate a percentage of my income for contributions to church and charities and count this just like bills. It's a good idea to put aside something for savings and/or paying down any outstanding loans every month. Then I add these up to say okay, here's how much I need each month to pay the bills. Subtract that from my monthly income and that's what I have for spending money. I get paid twice a month so I generally pay bills when I get paid. For most bills the due date is far enough ahead that I can wait the maximum half a month to pay it. (Worst case the bill comes the day after I pay the bills from this paycheck.)  Then I keep enough money in my checking account to, (a) Cover any bills until the next paycheck and allow for the particularly large bills; and (b) provide some cushion in case I make a mistake -- forget to record a check or make an arithmetic error or whatever; and (c) provide some cushion for short-term unexpected expenses. To be safe, (a) should be the total of your bills for a month, or as close to that as you can manage. (b) should be a couple of hundred dollars if you can manage it, more if you make a lot of mistakes. If you've calculated your expenses properly and only spend the difference, keeping enough money in the bank should fall out naturally. I think it's a lot easier to try to manage your money on a monthly basis than on a daily basis. Most of us don't spend money every day, and we spend wildly different amounts from day to day. Most days I probably spend zero, but then one day I'll buy a new TV or computer and spend hundreds.  Update in response to question What I do in real life is this: To calculate my available cash to spend, I simply take the balance in my checking account -- assuming that all checks and electronic payments have cleared. My mortgage is deducted from my checking every month so I post that to my checking a month in advance. I pay a lot of things with automatic charges to a credit card these days, so my credit card bills are large and can't be ignored. So subtract my credit card balances. Subtract my reserve amount. What's left is how much I can afford to spend. So for example: Say I look at the balance in my checkbook today and it's, say, $3000. That's the balance after any checks and other transactions have cleared, and after subtracting my next mortgage payment. Then I subtract what I owe on credit cards. Let's say that was $1,200. So that leaves $1,800. I try to keep a reserve of $1,500. That's plenty to pay my routine monthly bills and leave a healthy reserve. So subtract another $1,500 leaves $300. That's how much I can spend. I could keep track of this with a spreadsheet or a database but what would that gain? The amount in my checking account is actual money. Any spreadsheet could accumulate errors and get farther and farther from accurate values. I use a spreadsheet to figure out how much spending money I should have each month, but that's just to use as a guideline. If it came to, say, $100, I wouldn't make grandiose plans about buying a new Mercedes. If it came to $5,000 a month than buying a fancy new car might be realistic. It also tells me how much I can spend without having to carefully check balances and add it up. These days I have a fair amount of spending money so when, for example, I recently decided I wanted to buy some software that cost $100 I just bought it with barely a second thought. When my spending money was more like $100 a month, lunch at a fast food place was a big event that I planned weeks in advance. (Obviously, I hope, don't get stupid about ""small amounts"". If you can easily afford $100 for an impulse purchase, that doesn't mean that you can afford $100 five times a day every day.) Two caveats: 1. It helps to have a limited number of credit cards so you can keep the balances under control. I have two credit cards I use for almost everything, so I only have two balances to keep track of. I used to have more and it got confusing, it was easy to lose track of how much I really owed, which is a set up for getting in trouble." Ally bank has a free billpay service where you have the option of paying bills via eBills. Though I use Ally's billPay service (and I write about my experience with Ally in my blog), I haven't used eBills, but from reading your question, looks like this is what you are looking for. From Ally's site: What are eBills? An eBill is an online version of a bill or statement that can replace a traditional paper copy. Many large companies, like your electric, phone, cable and major credit card companies have the ability to send you eBills. To receive eBills at Ally, you must already receive your bill online at the biller's website. Ally will ask for the biller's website credentials to set up an eBill. Hope this helps. Hi guys, I have a difficult university finance question that’s really been stressing me out....  “The amount borrowed is $300 million and the term of the debt credit facility is six years from today  The facility requires minimum loan repayments of $9 million in each financial year except for the first year.  The nominal rate for this form of debt is 5%. This intestest rate is compounded monthly and is fixed from the date the facility was initiated.  Assume that a debt repayment of $10 million is payed on 31 August 2018 and $9million on April 30 2019. Following on monthly repayments of $9 million at the end of each month from May 31 2019 to June 30 2021.  Given this information determine the outstanding value of the debt credit facility on the maturity date.”  Can anyone help me out with the answer? I’ve been wracking my brain trying to decide if I treat it as a bond or a bill.  Thanks in advance, Yes.   A mortgage is a kind of debt.  Someone lends you money to buy your house, and you owe them the money, so you have debt. "I think it's worth pointing out explicitly that the biggest difference between a credit card (US/Canada) and a debit card (like your French carte de crédit) is that with a credit card, it's entirely possible to not pay the bill or to pay only the ""minimum payment"" when asked. This results in you owing significantly more money due to interest, which can snowball into higher and higher levels of debt, and end up getting rapidly out of control. This is the reason why you should ALWAYS pay off the ENTIRE balance every month, as attested to in the other answers; it's not uncommon to find people in the US with thousands of dollars of debt they can't pay off from misuse of credit cards."
