Birthday gifts for brother: what people actually spend
People spend $55.65 on an adult's birthday gift on average — per Empower, 2025. Every idea below carries its own price range and the date we checked it, so you can see where it sits against that.
This is the national figure for an adult's birthday gift, not a breakdown for a brother — no published survey we could find breaks spending down by relationship, and the per-relationship numbers you will see elsewhere carry no source.
$25–50
For his children, on his birthday, and why that is not a dodge
A brother with small children often values something for them above something for himself, and this only works if you understand why — otherwise it is a way of not buying him a present.

Something that is not a joke, for once
Between adult brothers the joke gift is the default, and it is worth naming what it actually is: a way of not choosing. It is funny once and it says nothing.

Something the two of you do, rather than something he keeps
Adult siblings run out of shared context surprisingly fast. You know who he was; you know much less about who he is, and objects are a poor way to close that.

$100–250
Just ask him — with a sibling this costs nothing
Asking a partner what they want defeats the point of the gift. Asking a brother does not, and that difference is worth using rather than working around.

Why the ranges, and why the dates
An exact price stops being true within weeks, and a list full of stale prices is worse than one with none — it looks precise while quietly misleading you. So each idea is published as the band it falls into, with the date we last checked, and you can judge how much weight the date still carries.
The spending figure is the more durable number and the more useful one. It answers the question behind the question: not what to buy, but whether the amount you had in mind is generous, normal, or thin for this particular relationship.
