The quantity of cash you keep in the bank may depend on how you choose to budget your finances. When budgeting using percentages, one of the most common and widely used approaches is the 50/30/20 rule. This budget guideline recommends dividing your money into the following three categories:
The term "needs" refers to all the costs you must spend to keep up a minimum level of living standards. Among other necessities, this includes shelter, utilities, and food. Anything you spend money on that isn't required, like eating out or entertainment is considered a "want." The fourth category includes funds specifically designated for saving or paying off debt.
If you use the budgeting strategy known as the 50/30/20 rule, the 20% of your income you set aside for savings might all be deposited into a bank account. Put this money into a high-yield savings account to create an emergency fund or save it for another short-term purpose.
The maximum amount of money that may be kept in a checking, savings, money market, or certificate of deposit account might be capped by financial institutions like banks and credit unions. These restrictions may be applied individually to each account or collectively across all your accounts. For example, the most you can have in a single bank account is $1 million, and the most in all accounts are $3 million.
Depending on your bank, the restrictions may be larger, lower, or none. If you are unsure whether or not your bank places restrictions on the amount of cash you are allowed to keep in your accounts, you should be able to find this information either on the bank's website or in the customer agreement you signed when you first opened your account. If you are unsure, you should contact your bank directly. You may also phone the bank and inquire if there are any deposit limitations.
You may pay your bills online or by writing checks if you have a checking account. If your checking account comes with a debit card connected to it, you can use it to make in-store and online purchases. In addition, you may connect a checking account to a savings account to simply move money back and forth between the two types of accounts. So how much money should you retain in your checking account? The response may vary depending on several factors, including:

First, let's look at it from the perspective of the budget. You base your budget on your paychecks and get paid every other week. If you want to make sure that your bills are paid, put aside enough money in your checking account to cover at least one-half of the amount of money they will cost you until the next time you get paid. You may boost this to the cost of a whole month's worth or even two months' worth of expenses if you want to construct a larger safety net for yourself.
The choice to retain more cash in checking may, in certain instances, be solely motivated by the desire to avoid a charge. For example, conventional banks often charge a monthly charge for checking accounts. But, if you keep a certain amount in your checking account or a certain amount in all of your bank accounts, you can avoid paying this charge.
Savings accounts often intend to retain the money you don't want to spend immediately. This may be money that you need for a goal with a shorter time frame, such as arranging a trip, or it could be money that you need for a goal with a longer time frame, such as purchasing a house. Moreover, savings or money market accounts are useful for stowing away an emergency fund if needed.
If you start a savings account to put money away for a particular purpose, such as a trip, a wedding, or the down payment on your first house, the total amount of money you put away will be defined by that purpose. For instance, you could need to set aside $3,000 for a vacation, $10,000 for a vehicle that's brand new to you, or $20,000 for a wedding.
