In Jainism there is no fixed or minimum amount of punya (merit) that guarantees a human birth. A human birth arises when the karmic balance includes enough positive deserving merit combined with the relative absence or shedding of heavy papa (demerit) karmas. The important point is: human birth is considered highly auspicious because it gives the soul the best opportunity for spiritual practice and ultimately moksha, but there isn’t a precise quota or threshold stated in Jain scriptures.

Key ideas:

• Human birth is the fruit of long-term karmic balance, not a simple number you can measure.
• It is precious because it enables direct effort toward liberation, unlike lower births where spiritual progress is harder.
• Digambar and Shwetambar traditions both affirm that human birth is favorable for spiritual practice, though they may differ on details of karmic theory.

If you’d like, I can point you to specific Jain texts or stotras that discuss punya and human birth in more detail.
