You got the invitation, you know it's a big deal, and you have exactly one question: how much cash is normal? Here's the custom — plus what to do if you'd rather not just write a check.
A bar mitzvah (for a boy, at 13) or bat mitzvah (for a girl, at 12 or 13 depending on community) marks the moment a Jewish child becomes religiously accountable for their own actions — literally, "one to whom the commandments apply." The ceremony itself is usually a Shabbat or weekday service where the teen leads part of the prayers and reads from the Torah for the first time, followed by a party that can range from a modest kiddush lunch to a full-blown celebration.
The gift-giving custom that comes with it — giving money in multiples of 18 — is one of the most recognizable in Jewish culture, and it's worth understanding rather than just copying. In Hebrew, letters double as numbers (a system called gematria). The word chai (חי) means "life," and its two letters add up to 18. A gift of $18, $36 ($18×2), or $180 ($18×10) isn't just a round-ish number — it's a small, literal blessing: "may you have a long life."
| Your relationship | Typical range |
|---|---|
| Classmate, casual friend of the family | $18–$36 |
| Closer friend, neighbor, coworker's child | $36–$72 |
| Aunt, uncle, close family friend | $100–$180+ |
| Grandparent, very close family | $180 and up, per family means |
These are ranges people commonly land on, not a script — give what's comfortable for you. If the party is clearly a large, catered affair, some guests scale up slightly to reflect the cost of hosting; that's a personal choice, never an obligation.
