Hello!

That will depend where in Indonesia do you live, the benefits you get from the company you will work for and the load of work you will do.

Is 10 million a nice salary for expats? thanks

No, it's a bit rubbish.
Fine for plodding on but getting nowhere, but useless if you want to save anything.
I easily live on less than ten per month, but I earn a heck of a lot more so my bank account looks rather nice.

As you expressed an interest in English teaching, take a peek at the definite article and how to use it.
If, as suggested in your profile, this is an English teaching job, hope Luke chips in with advice.

For 10 million a month I would steer clear as thats too low unless your employer is providing housing and transport for free.

The cost of living here is less than 10 mil a month but I would look at Numbeo.com as its useful.

Who is offering you this?
