How do you keep track of the money in their checking account?

To keep track of money in a checking account, regularly monitor transactions through online banking or a mobile app, which provides real-time updates on account activity. Additionally, maintaining a personal ledger or using budgeting software can help track expenses and deposits. Setting up alerts for low balances and reviewing bank statements monthly can also ensure you stay aware of your financial situation. Lastly, regularly reconciling your records with bank statements can help identify any discrepancies.
