A confounding variable is an extraneous variable that is related to your independent variable and might affect your dependent variable. In an ideal study, there will be no confounding variables.
For example, student accounts have a limit of $100 limit per day, while non-business accounts usually are limited to $500 withdrawals a day. For business accounts, the bank offers $1000 withdrawals in one day. Chase also offers customers a withdrawal limit of $1000 every 24 hours.
The traditional withdrawal approach uses something called the 4% rule, which says you can withdraw about 4% of your principal each year. Using this rule you could withdraw about $400 for every $10,000 you have invested. Some of that $400 would have to go for taxes. If this is the only way you are looking at how much you can spend in retirement, youâre looking at it wrong.
