How much to give for a 40th birthday in Australia
The invite says "no presents, just your presence" — and then, in smaller type, mentions a wishing well. So you're left doing the maths in your head on the way to the party, wondering whether $50 looks stingy and $200 looks like you're trying too hard.
Here's the short version: most Australians give between $50 and $150 for a 40th birthday, and $100 is the single most common amount. Where you land inside that range depends almost entirely on how close you are to the person turning 40, not on how fancy the venue is.
This guide walks through what to give at a 40th by relationship, what changes when the whole friendship group is chipping in together, and how the amount compares to other milestone birthdays. We've pulled the numbers from real gifts sent through birthday wishing wells on PocketWell, so these are actual amounts Australians gave — not a survey of what people say they'd give.

How much should you give for a 40th birthday?
For a 40th birthday in Australia, $100 is the standard cash gift from a friend, $50 is fine from a wider-circle friend or colleague, and $150–$300 is typical from close family.
The table below breaks the 40th birthday gift amount down by what gift etiquette calls your relationship tier — how close you are to the person, which is the single biggest factor in what guests actually give.
| Your relationship to them | Typical 40th birthday gift amount | Go higher if |
|---|---|---|
| Close friend or best mate | $100–$150 | You're also part of the crew organising the party |
| Friend from the wider circle | $50–$100 | You're bringing a plus-one |
| Sibling | $150–$250 | You're splitting one bigger gift between fewer siblings |
| Adult child giving to a parent | $150–$300 | You're combining with siblings for an experience gift |
| Parent giving to their adult child | $200+ | It doubles as a contribution to something they're saving for |
| Cousin, aunt, uncle, niece or nephew | $100–$150 | You're close enough to be at the sit-down dinner |
| Colleague or workmate | $20–$50 | It's your direct manager or someone you work with daily |
| Neighbour or acquaintance | $50 | They've done you a good turn recently |
| Partner's friend (you're the plus-one) | Nothing extra — your partner gives for both of you | You know the birthday person well yourself |
Methodology note: these ranges reflect real gifting patterns seen across PocketWell birthday pages, cross-checked against typical Australian household spending on gifts as reported by the Australian Bureau of Statistics. They're PocketWell's own platform data — not neutral third-party research — so treat them as a well-grounded starting point rather than a rule.
What real 40th birthday gift amounts look like
Across 169 completed gifts sent to 40th birthday wishing wells on PocketWell, the median amount was $100 and the middle half of gifts fell between $50 and $150.
What stands out in the data isn't the spread — it's the clustering. Australians giving a 40th birthday cash gift overwhelmingly pick one of two round numbers:
- 40% give exactly $100
- 22% give exactly $50
- About 72% land somewhere between $50 and $100 all up
- Only 4% give under $50
- Around 7% give more than $200
That clustering shows up right across the birthday category. Of the 1,426 completed birthday gifts on PocketWell, 82% are multiples of $25 — people round to $25, $50, $75, $100 and $150 rather than landing on odd figures.
Birthdays are PocketWell's second-biggest occasion after weddings, making up about a quarter of all gifts sent through the platform. A typical 40th birthday page collects gifts from around 14 guests, which is a useful reality check: you're one contributor among a dozen or more, and the total is what buys the trip or the good bottle — not any single gift.
Not sure where you sit? The gift amount calculator will give you a suggested figure based on your relationship and the occasion in about ten seconds.
How your relationship changes the amount
Relationship tier explains more of the variation in 40th birthday gift amounts than income, city or venue does. Someone giving $50 in Perth and someone giving $50 in Sydney are usually in the same position: friendly, but not in the inner circle.
Close friends are the group most likely to give $100. If you've known them for twenty years, you're in the group chat that planned the party, and you'll be there for the speeches, $100–$150 is the comfortable zone.
Wider-circle friends — the ones you see a few times a year, the school-gate parents, the old workmate who stayed in touch — give $50–$100 without anyone blinking. This is the most common position guests find themselves in, and $50 is genuinely fine.
Siblings and adult children sit highest. A 40th is often the birthday where the family goes in on something substantial: a weekend away in the Blue Mountains, a case of good wine, a contribution to a bigger trip. Splitting $600 three ways between siblings lands each of you at $200.
Colleagues almost never give individually at a 40th — it's a workplace collection, which we cover next. If you're going solo, $20–$50 is the norm, and nobody is checking.
Couples give once. If you and your partner are both invited, one gift covers you both. Bumping it up modestly — say $150 instead of $100 — is a nice touch, not an obligation.
Chipping in on a group gift for a 40th
When a group gift is running, most Australians contribute $20–$50 each, and the pooled total does the heavy lifting. Group-gift pooling — where a dozen people put in small amounts toward one bigger present — is how most 40ths actually get funded.
The median contribution to group gifting pages on PocketWell is $50, across 776 completed gifts. That's half the individual birthday median, which makes sense: you're one of many, and the organiser is aiming at a total, not a per-person figure.
A few things that make a 40th group gift work:
- Name the target, not the per-head amount. "We're aiming for $800 toward their Japan trip" lets people give $20 or $100 without it being visible who did what.
- Set a deadline before the party, not on the day. Late contributions are the main reason organisers end up chasing people.
- Let people give what suits them. A workmate on a tight fortnight giving $20 and a close mate giving $150 both belong in the same collection.
If you're the one wrangling it, a group gifting page means one link to share and no cash to collect, count or carry around. We've written a fuller guide to running a birthday whip-around in Australia if you're organising rather than contributing.
Does the party style change how much you give?
Not as much as people expect. The old "cover your plate" rule — give roughly what your seat costs the host — comes from wedding etiquette and doesn't transfer cleanly to a 40th.
A 40th might be a backyard barbecue in Brisbane, a long lunch on the Gold Coast, or a hired room in Melbourne with a band. The host's spend on you isn't really the point, and most people don't know the per-head cost anyway.
Where the party style does nudge things:
- A destination or weekend-away 40th — you're already spending on flights and accommodation. A smaller gift, or a card and a good bottle, is completely reasonable.
- A "no gifts, just come" party — take them at their word, but a card with $50 or something small is still welcome if it feels wrong to arrive empty-handed.
- A wishing well or gift fund mentioned on the invite — this is the host signalling that money is genuinely the preferred gift. Give what you'd have spent on a present.
- A milestone with a stated purpose — if they're raising money toward a specific trip or project, contribution gifting (giving toward one named thing rather than a general pool) tends to pull slightly higher amounts, because people can see what their $50 is buying.
Cash, gift card or a wrapped present
At a 40th, cash and gift funds have quietly become the default, largely because people at 40 already own the homewares. A wrapped present is still lovely — it just needs to be specific.
Cash or a gift fund works when the host has asked for it, when you don't know their taste well, or when you're contributing to something bigger. On PocketWell, 89% of 40th birthday gifts came with a written message attached, which is the part that stops money feeling impersonal.
Gift cards are a solid middle ground. Worth knowing: gift cards sold in Australia must be valid for at least three years from purchase, and businesses can't charge most post-purchase fees — the ACCC sets out the rules. Check the expiry before you buy anyway.
A wrapped present wins when you know them properly. The 40th gifts people remember tend to be specific rather than expensive: the out-of-print book they mentioned once, a print of a place that means something, tickets to see a band they loved at 20.
A nice hybrid: put in $80 toward the group gift and bring a $20 card-and-something small to actually hand over on the night. You get the personal moment without splitting your budget in a way that weakens both.
How a 40th compares with other milestone birthdays
A 40th and a 50th attract almost identical gift amounts in Australia — both sit at a median of $100, with the middle half of gifts falling between $50 and $150.
| Milestone | Median gift | Middle 50% of gifts | What drives it |
|---|---|---|---|
| 40th birthday | $100 | $50–$150 | Peer group is established; group gifts are common |
| 50th birthday | $100 | $50–$150 | Similar guest mix, slightly more family-heavy |
| Birthdays overall | $100 | Varies by age | Kids' and 21st parties pull the wider range down |
Both figures come from PocketWell's completed gift data — 133 gifts across 40th birthday pages and 140 across 50ths. The similarity is the useful finding: if you've given at a 50th recently, you already know what a 40th costs.
Younger milestones sit noticeably lower. A 21st is usually a $30–$50 occasion because the guest list is mostly other 21-year-olds. By 40, the friendship group has more capacity, and the amounts move up accordingly. If you want the friend-specific breakdown, we've covered how much to give a friend for their 40th and how much to give a friend turning 50 separately.
Frequently asked questions
Q: Is $50 enough for a 40th birthday?
A: Yes — $50 is a completely normal 40th birthday gift amount in Australia, and it's the second most common amount guests give. About 22% of gifts to 40th birthday pages on PocketWell are exactly $50. It sits comfortably for a wider-circle friend, a colleague, a neighbour, or anyone who's already spent money getting to the party. If you're a close friend or family and $50 is what works this month, give $50 and write a good message — the note is the part people keep. Nobody at a 40th is auditing individual amounts, and if the gift went through a wishing well, guests can't see what anyone else gave anyway.
Q: How much should I give my brother or sister for their 40th?
A: Siblings typically give $150–$250 for a 40th, and often more when they combine with other family members for one larger gift. A 40th is a common point for siblings to go in together on an experience — a weekend away, a nice dinner, tickets to something — rather than separate presents. If there are three of you splitting a $600 gift, that's $200 each. If you're the only sibling, $200–$300 is a reasonable single gift. Family gifts sit at the higher end of the range for every milestone birthday, so don't benchmark yourself against what their friends are giving.
Q: What's a good amount to give if I'm going as someone's plus-one?
A: One gift covers a couple, so your partner's gift is your gift too. If you barely know the birthday person, you don't need to give anything separately — turning up and being good company is genuinely enough. If you know them well in your own right, bumping the joint gift up modestly makes sense: $150 instead of $100, for example. The one thing to avoid is two separate gifts from the same household arriving on the same night, which tends to confuse the host more than it impresses them.
Q: Is it rude to give cash for a 40th birthday?
A: Not at all — at a 40th, money is often the most useful gift you can give. People turning 40 usually have the homewares sorted and are more likely to be saving toward a trip, a renovation or something they've had their eye on. Cash lets them put it there. The thing that makes a cash gift feel personal is the message. On PocketWell, 89% of 40th birthday gifts arrive with a written note, and hosts consistently say that's the part they read twice. If the invite mentions a wishing well or gift fund, that's an explicit signal money is welcome.
Q: How much do people give at a 40th in Sydney compared to a smaller town?
A: The differences are much smaller than you'd think. Gift amounts track your relationship to the person far more closely than they track postcode or venue cost. A close friend in Sydney and a close friend in Adelaide are both most likely to give $100. Where a city difference does show up, it's usually indirect — bigger cities tend to have larger guest lists and more group gifts, which spreads the total across more people rather than raising anyone's individual amount. Don't inflate your gift because the party is at an expensive venue.
Q: Do I still give a gift if the invite says no presents?
A: Take the host at their word, but a card with a modest amount inside is rarely unwelcome. "No presents" usually means "don't buy me another candle" rather than "we will be offended by generosity". A middle path that works well: bring a card with $50, or something small and specific like a good bottle or a framed photo. If several people in your group are unsure, agree between yourselves to either all give or all not give — the awkwardness comes from half the table arriving with something and half arriving without.
Q: Does the birthday person keep the full amount if I give through a wishing well?
A: Yes — on PocketWell the host receives 100% of the gift amount. It's free for hosts, with no setup fees or subscriptions. Guests cover a 3.5% platform fee plus standard payment processing, and the exact total is shown to you before you confirm, so there are no surprises. Payments go through securely with Apple Pay, Google Pay or a debit or credit card. Payouts to the host are sent weekly on Tuesdays via Stripe, with most arriving one to three business days later — the first payout takes five to seven business days while Stripe completes its verification checks. The FAQ page covers fees, payouts and security in more detail.
Final tips for landing on the right amount
If you take one number away: $100 is the safe, standard answer for how much to give for a 40th birthday in Australia, and $50 is genuinely fine when money is tight or you're on the edge of the friendship group.
Three things worth remembering:
- Set the amount from your relationship, not the venue. The nice restaurant isn't a bill you're helping pay.
- Write the message. Nearly nine in ten guests do, and it's the part the birthday person actually keeps. Two specific sentences beat a generic paragraph.
- Give what fits your fortnight. If you're working to a budget, Moneysmart has practical guidance on planning for gifts and celebrations. A thoughtful $50 lands better than a stretched $200 you'll feel next week.
And if you've been handed the job of organising the collection rather than just contributing to it — the wishing well is the easy way through. Setting up a 40th for someone? Create a free 40th birthday wishing well — it's free for hosts, guests give from their phone in under a minute, and there's no cash to chase, count or carry home at the end of the night.
