How much does it cost to use a credit and/or charge card when traveling outside the country?

It depends upon the service provider. Different service provider has different charges and facilities. I prefer that the best service provider is Western Union. Its service is nice in reasonable charges.

It is very cheap,easy and comfortable to use Credit Card abroad. I use MasterCard for traveling and haven't problem with cash
