Can anyone tell me what is a realistic budget/income level to travel the world?

I’m aiming for $10K a month income but is that enough?

I’m in the UK, family of four with two under 10’s.

We would rent out our house so most expenses at home would go.

We don’t want to back pack so it would be air bnb and hotels.. our top destinations are the US, Canada, NZ, OZ, India and Africa and also Europe.

Anyone doing this and am I way under with my income goals?
