Answer

In Jain temple and community usage, nakro usually means a fixed offering or sponsorship amount for a specific puja, vidhi, or religious event. In Gujarati usage, it is also described as a kind of religious levy / fixed dues. Jain temple notices commonly use the word this way for assigned sponsorship amounts. ( rekhtagujarati.org)

Explanation

So, if someone says “nakro” in a Jain context, they generally mean:

• a set amount for a temple ritual,
• a sponsorship contribution,
• or a designated payment tied to a particular religious privilege or service. ( jsocf.org)

Spiritual Understanding

In Jain Dharma, the value is not in the money itself, but in the भावना:

• श्रद्धा, devotion
• विनय, humility
• and participation in धर्मकर्म with a pure heart.

A nakro is therefore understood as a way to support sacred activities, not merely as a fee. ( jsocf.org)

Takeaway

Nakro = a fixed Jain religious contribution/sponsorship amount. If you want, I can also explain the difference between nakro, boli, and gheeboli in Jain usage.
