An account balance is the amount of money available in a financial account at a specific point in time. This can refer to various types of accounts, such as a bank account, credit card account, or investment account. The balance can be positive, indicating available funds, or negative, indicating debt. Account balances are important for managing finances, as they help individuals and businesses track their spending and savings. Regularly checking the account balance ensures that one stays within budget and avoids overdraft fees or exceeding credit limits.
