In Jain Dharma, there is no fixed limit on how much money a Jain can earn.

A Jain may earn as much as needed through honest, non-violent, and ethical means, but the earning should not involve:

• हिंसा or harm to living beings
• cheating, fraud, or dishonesty
• exploitation
• excessive greed or attachment

The Jain ideal is:

• Right livelihood
• Less greed, more contentment
• Use wealth for dharma, family duty, charity, and support of good causes
• Do not become attached to money

So, a Jain can earn money, but the real principle is how it is earned and how it is used.

In short: earn with purity, keep limited attachment, and use wealth responsibly.
