Birthday gifts for son: 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 son — no published survey we could find breaks spending down by relationship, and the per-relationship numbers you will see elsewhere carry no source.

For a small son, the year he starts choosing rather than receiving
Around four or five a birthday stops being an event that happens to him and starts being an event he decides on. The gift that lands is the one that lets him decide something small back.

For a nine-year-old son, between the toy and the object
Nine is the age when toys stop working and adult objects do not fit yet. The gift that lands is a real thing his size — not a toy dressed as one, not an adult item scaled down.

$50–100
For a teenage son, the thing he would not ask you for
The age when a boy stops asking, and the money spent on him quietly stops working. Nothing on the wishlist is the wrong answer to this — but the interesting one is a category off it.

$100–250
For an adult son, buy for the life he actually lives
The mistake a parent makes at this stage is buying the life they remember him having. He has a different one now, and the good gift acknowledges it plainly.

Also worth a look
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.
