There is non because different people has different kinda of travel budget.

Example I can only spend rm500 for 2 pax in hatyai for 3 days 2night while my colleagues spend more than 2k due to different hotel quality, food, shopping places
And also

I spend around 11k for 1 pax 14day Europe trips with budget hostel/public transportation and no dining no much shopping while colleagues spend more than 20k same destination with driving different hotels and restaurants dining in.

So it's better ask you self.  How much you willing to spend on a single trip. Then plan from there.
