Technically, there is no limit to how much money you can have in savings or a checking account. Banks do not cap the amount you can deposit or keep in your account. However, it's essential to know that the Federal Deposit Insurance Corporation (FDIC) provides coverage up to $250,000 per depositor, per account ownership type, and financial institution. This means if your bank fails, your money is insured up to this limit, but any funds in excess could be at risk.
