Hello there!
Your question asks how much is it to open a checking account.
Answer: You usually don't pay to open a checking account, but mostly would need to put in a minimum deposit.
Most of the time, banks don't charge a customer to open up their own checking account, due to the fact that people are going to use that account to make deposits and withdrawals anyways. If banks were to charge people to open an checking account, people would not choose that bank to hold their money.
Most of the time, banks do not charge customers to open a checking account, but they require customers to put a minimum deposit in the account. The minimum deposit could be around $25 or higher. Banks do this in order to maker sure that the customer has funds in the account so they're technically using it, rather than having a customer open up a checking account and not use it at all.
I hope this helps!
Best regards,
