Presumably "actual cost" means the literal mechanical requirements for the system e.g. the electricity and server power to detect the overdraft and send the credit
Yeah I was being generous with a couple of cents, especially since even without overdraft they would have the mechanism for detecting an account not having enough to cover a transaction.
Which is like a fraction of cent at most.
