If you are planning to set your budget for the trip to Vietnam and you need to have a particular amount in your mind first so that you can be prepared before so if you are planning for a journey of one week for two people to Vietnam, then you can expect the budget to go up to a range of 1200* dollars to 2000* (* price may vary) dollars entirely depending upon the mode you chose for traveling and your expenses after you visit the place. But you can have a good stay with the budget mentioned above.
