Dear aspirant,

It varies, depending on one's qualifications, expertise, city the doctor is practicing in and whether it's a private practice or a job. 

I agree to a fact that it takes a long time to establish oneself in this field. To start with, could be anywhere between 10k-20k per month. Even a good experienced homeopathic doctors earning is around 1lakh a month as well. But yes, hell lot of hardwork, dedication, devotion and passion is required and eventually, the work satisfaction, happiness in helping others and peace of mind with the wisdom gained wind over the monetary gains. 

Hope the answer is helpful.

All the best.
