What's the purpose of having separate checking and savings accounts?
"For some people, it's easier to stick to a budget if they have separate checking and savings accounts because they can deposit funds directly into their savings account and not have those funds accessible by debit/credit card, checks, etc. This allows people to pay themselves first and accumulate savings, while making it slightly more difficult to spend those savings on a whim. One a more technical/legal note, one key difference in the United States comes from Regulation D. §204.2(d)(2) of the law limits you to six withdrawals from savings and money market accounts. No such limit exists for checking accounts. Regulation D also forbids banks from paying interest on business checking accounts.  In the simplest case, checking accounts and savings accounts are a tradeoff between liquidity and return. Checking accounts are much more liquid, but won't necessarily earn interest, while savings accounts are less liquid because of the withdrawal limits, but earn interest. Nowadays, however, sweep accounts blur this line somewhat because they function like checking accounts, in that you can write an unlimited number of checks, make an unlimited number of withdrawals, etc. but you can also earn interest on your account balance because some or all of the funds are ""swept"" into an investment account when not in use. The definition of ""in use"" can vary from business to business and bank to bank." A checking account is instant access. It can be tapped via check or debit card.  A savings account is supposed to be used to accumulate cash for a goal that is is longer term or for an emergency.  Many people need to separate these funds into different accounts to be able to know if they are overspending or falling short on their savings. In the United States the Federal Reserve also looks at these accounts differently. Money in a checking account generally can't be used to fund loans, money in a savings account can be used as a source of loans by the bank. An even greater percentage of funds in longer term accounts can be used to fund loans. This includes Certificates of Deposit, and retirement accounts. If your debit card/ATM card is stolen or lost, someone else might be able to withdraw money from the checking account that it is tied to, or buy things with the card and have the money taken out of the checking account to pay the merchant. Subject to daily withdrawal limits imposed by your bank, a considerable amount of money could be lost in this way. At least in the US,  debit or ATM cards, although they are often branded Mastercard or Visa, do not provide the same level of protection as credit cards for which the liability is limited to $50 until the card is reported as lost or stolen and $0 thereafter.  Note also that the money in your savings account is safe, unless you have chosen an automatic overdraft protection feature that automatically transfers money from your savings account into the checking account to cover overdrafts. So that is another reason to keep most of your money in the savings account and only enough for immediately foreseeable needs in the checking account (and to think carefully before accepting automatic overdraft protection offers). These days, with mobile banking available via smartphones and the like, transferring money yourself from savings to checking account as needed might be a preferred way of doing things on the go (until the smartphone is stolen!) Additionally, it used to be the case that savings accounts would have a noticeably higher interest than checking accounts (if the checking account paid any at all).  So you would attempt to maximize your cash working for you by putting as much as you could into the savings account and then only transferring out what you needed to cover bills, etc into the checking account.
"I've been in a very similar situation to yours in the past.  Since the company is reimbursing you at a flat rate (I assume you don't need to provide documentation/receipts in order to be paid the per diem), it's not directly connected to the $90 in expenses that you mention.  Unless they were taking taxes out that would need to be reimbursed, the separate category for Assets:Reimbursable:Gotham City serves no real purpose, other than to categorize the expenses. Since there is no direct relationship between your expenses and the reimbursement, I would list them as completely separate transactions: Later, if you needed to locate all of the associated expenses with the Gotham trip, gnucash lets you search on memo text for ""Gotham"" and will display all of the related transactions.  This is a lot cleaner than having to determine what piece of the per diem goes to which expenses, or having to create a new Asset account every time you go on a trip." "The answer is, there are a lot of answers! It always seems so daunting to start saving when you're living paycheck to paycheck and anticipate more bills on the way (kids are expensive!!). Start small, and make it automatic if you can. If you can take $25 out of every paycheck and put it into a savings account, and do this automatically using your bank's Bill Pay system, that will go a long way. It's about setting up a new habit for yourself, and increasing as you can. One way I've heard it phrased is ""Pay yourself first"".  Don't set unrealistic expectations for yourself, either. You need to start building a savings account to cover emergencies, not just future purchases. If something happens and you can't get a paycheck for a week, a month, 2 months, how will you pay your bills? Set up a savings account just for that purpose and don't touch it unless it's a true emergency. There are several banks out there that will let you set up multiple savings accounts and mark them for specific purposes, like CapitalOne's 360 accounts. Set one up for the emergency account that gets your automatic per-paycheck deposit, then set up another one for ""fun money"" or ""new home fund"" or whatever else you want to save up for.  Starting the savings process is hard, no doubt about it. You need to learn how to budget with the money you have after ""paying yourself first"". But the important part is to stick with it. Consider your savings account as another ""mandatory"" utility. You have to pay it $25/mo or risk...I don't know...a smack on the back of the head. If you wait until the end of the month to see what you have left after everything else, you'll find you don't have anything left. If you can set it up through your bank so when you get your paycheck it automatically puts $25 into a savings account, then you'll never have that $25 burning a hole in your pocket. If your paychecks aren't direct deposit, and you're physically cashing them when you receive them, then tell the bank teller to put $25 into your savings account.  You can do it! Make sure your wife is on board and you communicate the importance of setting up a savings account and work together to make it happen. Be patient, and realize that $25 may seem like a trivial amount to put away now, but after 24 paychecks (1 year depending on pay schedule), that's $600! (Plus interest but rates are too low now to worth noting that)." I don't use a rule of thumb for this. Instead, I use a budget.  Throwing money into a savings account for the purpose of building a savings account is okay, but I only put money into a savings account that I have a purpose for.  For example, there are bills that come up once a year, such as insurance premiums, property tax, annual subscriptions and memberships, etc. I plan for these in my budget each month, and the money goes into my savings.  I also have an emergency fund, which is used in the event that a large, one-time, unexpected expense comes up that I hadn't planned for. I have a goal for how large I want this fund to be, so I put money in savings until it is built up to the level I want it at.  There are other long range saving goals I have: my next car, vacation, furniture replacement, technology replacement, etc. Each of these gets some money each month, which goes into savings.  I also have retirement savings in the budget, but that doesn't go into the savings account; it gets invested in my retirement account.  My point is that instead of arbitrarily choosing a percentage of your income to put into a savings account, think about the purpose of that money. That will help you determine how much needs to be saved, and it will also help motivate you to do so. "Parts of what you want are possible, but taken as a whole, you're out of luck. First of all, there is no master database of every cardholder in the country.  The only way to check if information is correct is to ask the issuing bank.  The AVS system is a way to automate doing so, but it's possible to call the bank directly and verbally verify the address.   That means you're subject to the whims of what the issuing bank chooses to support.  Banks that are part of the Visa and MasterCard networks generally only verify the numeric parts (address, apartment number, zipcode).  AmEx can also verify the cardholder name.  But if the bank doesn't have support for validating something, you can't validate it. Separately, there is a ""verify-only"" transaction which some processors support, which will do exactly what you want:  Return AVS values without ever charging the card.  However, processors require you to have the ""approved merchant account"" you don't want to have to have.  Without being a merchant, you shouldn't have access to other people's credit cards anyway.  Would you really want anyone in the country to be able to verify anyone else's address whenever they want? In short, whatever purpose you have for wanting this probably falls into one of three categories:" "A savings account and a checking account (or a ""demand"" account, or a ""transactional"" account) have different regulations.  For example, fractional reserve requirements are 10% against checking accounts, but 0% against savings accounts.  The theory is that savings accounts are sticky, while checking accounts are hot money. So the Fed wants to stop banks from creating accounts that are regulated as savings accounts but have the features of checking accounts.  In the past, this was done by forbidding banks to pay interest on checking accounts.  They eliminated that rule back in the inflation years, and instead imposed the rule that to qualify as a savings accounts for regulatory purposes, banks must discourage you from using them as transactional accounts.  For example, by limiting the number of withdrawals per month that can be made from a savings account. If the Fed gave up on trying to enforce a distinction, I suspect there would soon no longer be a distinction." Why do savings accounts for businesses offer less yield than bank accounts for individuals?  The money held in savings account on a collective average substantial amount stays with the Bank. The Bank is better able to predict and thus invest this money in individual savings account in market to make more money. Money held in Business accounts are unpredictable and can get withdrawn, the Bank is thus not able to predict the behaviour and hence not able to invest this better to get good returns, hence the interest offered is low. Most Banks have special products for Businesses that would give better return but come with some kind of lock-in or minimum balances. When I moved banks.  I had my old bank cut a cashier's check.  It isn't a check you write. They write it and give it to you.  I then took the cashier's check to my new bank to deposit it. "As others have said, the decision is a very personal one. Personally, I think you have a good idea. For those of us that thrive in structured systems having a detailed breakdown and distribution of assets is a great idea. I recommend going one step further however. Instead of having a single ""Necessities"" account have a division here. 1 account for ""Bills"" and another for ""Living Expenses."" Your Bills account should recieve the funds to pay your monthly expenses such as Rent, Utilities, Insurance. Living Expenses is for day to day spending. I recommend this because your Bills are generally a fairly fixed expense. Keeping your flexible spending separate allows you to manage it more carefully and helps prevent overspending.  I keep my Living Expenses in cash and divide it up by the number of days before my next check. Every day I put my portion of the Living Expenses in my wallet. This way I know that I can spend as much money in my wallet and still be fine for the rest of the pay period. I also know that if I want to go out to a nice dinner on Friday, it would be helpful if I have money left over at the end of the day Monday through Thursday."
