How much to spend on an 18th birthday gift
Eighteen is one of the biggest birthdays anyone has in Australia, and the gift usually reflects that. The calculator below is already set to a milestone eighteenth. Tell us your relationship and how close you are, and it will adjust from there.
Recommended range
$75 to $120 is a comfortable range
Close friends sit near the top of the non-family range, which tracks with what Australian surveys report people spend on friends they consider genuinely close. This is also where the unspoken rules of Australian gift-giving bite hardest: a generic gift here reads as low effort, even at a decent price.
Turning 18 is a milestone birthday in Australia, and gifts typically step up by around fifty per cent for milestones. That premium is already built into the range above.
Ranges are a social norm, not a rule. The right amount is the one that does not strain you.

Questions
Is 18 always treated as a milestone birthday?
Yes. Eighteen carries the same fifty per cent premium as the other big milestones in this calculator, on top of whatever your relationship and budget settings already suggest.
Does the amount change if it's a big 18th party rather than a small one?
The calculator prices the gift, not the party. If you are also contributing to the party itself, that is a separate cost on top of the range below.
