How Much to Give a Grandchild for Their Birthday

How Much to Give a Grandchild for Their Birthday

There's a particular kind of quiet stress that comes with grandparent gifting. You want the amount to feel generous without making the other side of the family feel awkward, and you'd rather not hand over something the child opens, glances at and forgets by dinner.

So how much to give a grandchild for their birthday? In Australia, most grandparents land somewhere between $50 and $200, with $100 the single most common figure — and the right number depends far more on the child's age, your budget and how many grandkids you have than on any rule of etiquette.

This guide walks through typical amounts by age, what changes for a milestone birthday, how to keep things fair across a growing family, and the practical bits — like what happens when the party is interstate and you're sending money to a online birthday wishing well rather than slipping a note into a card.

Last updated: August 2026.

Key takeaways

• Most Australian grandparents give between $50 and $200 for a grandchild's birthday, and $100 is the most common single amount.
• Across birthday gift pages run through PocketWell, the median gift is $100 and the average is around $105 — birthdays are our second-largest event category by gift volume after weddings.
• Age matters more than the relationship. Under-fives usually receive money that goes into a savings account or a bigger shared present; teenagers and young adults spend it themselves.
• Milestone birthdays — 1st, 16th, 18th, 21st, 30th, 50th — typically get a step up, often double the usual amount, and are the ones families most often pool for.
• Consistency beats generosity. Giving each grandchild a similar amount at the same age is the thing most families quietly keep score on.

Grandparent birthday gift amounts at a glance

Here's the shape of it before we get into the why. These are guide ranges, not rules — the bottom of each range is completely respectable.

Methodology: these ranges reflect real gifting patterns we see across birthday pages on PocketWell — 1,355 completed gifts across 260 birthday events at the time of writing — alongside the broader Australian norms reported in family and etiquette guides. They're PocketWell's own platform data, not neutral third-party research, and they cover people who chose to give money online rather than in an envelope, so treat them as a sense-check rather than a benchmark.

How much should grandparents give a grandchild for their birthday?

$100 is the most common grandparent birthday gift in Australia, with $50 and $200 the next most popular amounts. Anywhere in that $50–$200 band reads as thoughtful and appropriate.

The data backs the instinct. Across birthday wishing wells run through PocketWell, the median gift is $100, the average is about $105, and roughly eight in ten gifts land somewhere between $50 and $200. Almost a third of all birthday gifts are exactly $100 — people like a round number they don't have to explain.

That clustering matters more than it sounds. Four out of five birthday gifts we see are round figures — $20, $50, $100, $200 — which tells you nobody is calculating a precise amount. They're picking the number that feels right for the relationship and moving on. You can do the same.

What genuinely shifts the figure:

• Your budget. This is the honest first filter, and there's nothing to apologise for. A card with $30 and a note about the child's first day of school beats a strained $200.
• How many grandchildren you have. Six grandkids at $100 each is $600 a year in birthdays alone, before Christmas. Families with larger broods almost always sit lower per child, and that's completely normal.
• Whether it's a milestone. First, 18th, 21st and the round decades usually get a step up.
• Whether other family members are pooling. If the parents are collecting for a bike or a laptop, a smaller contribution to something big often lands better than a standalone gift.

Birthday money for grandkids by age

Age is the strongest predictor of how a grandchild's birthday money is actually used — which is why it should shape the amount more than anything else.

Under five. The money isn't for the child, realistically — it's for the parents to put toward a savings account, an education fund, or something the child needs. This is the age where grandparents most often give a larger amount knowing it'll be saved. Interestingly, our data shows no drop-off here: for children aged five and under, the median birthday gift across nearly 900 contributions is still $100. Our first birthday gift amount guide goes deeper on that particular milestone.

Primary school age. Six to twelve is where a physical present usually reclaims centre stage, and the money component tends to drop to $30–$50. A nice middle ground is a smaller amount plus an outing — the shops, the movies, a day out with Nan and Pop that they remember longer than the cash.

Teenagers. From about thirteen, money becomes the most useful gift you can give, and teenagers are genuinely pleased to receive it. $50–$150 is the usual band. If you'd like a steer on the party-age norms more broadly, it's worth checking what other guests at that age tend to give before you settle on a figure.

Adult grandchildren. Once they're working, the amount often settles back to $50–$100 for an ordinary birthday and rises again for milestones. The gesture matters more than the figure by this point.

A quick sanity check before you decide: if you're not sure whether money or a present will land better, ask the parents. It is not an awkward question, and they'll almost always tell you straight.

What to give for a milestone birthday grandchild gift

A milestone birthday grandchild gift is typically double the usual amount — so if you'd normally give $100, $200 is the standard step up for a 1st, 16th, 18th, 21st or a round decade.

Milestones are also where contribution gifting comes into its own. That's the term for several people putting money toward one larger, named goal — a car deposit, a first overseas trip, a laptop for uni — rather than everyone buying separate presents. It's the difference between a grandchild receiving eleven $50 gifts and receiving one $550 contribution toward something they actually wanted.

For 18ths and 21sts specifically, grandparents often give the single largest gift in the room. Our 18th birthday gift amount guide breaks down what everyone else at the party tends to give, which is a useful reference point if you want to sit comfortably above the friend-group average without overshooting.

If the family has set up a page for the milestone, contributing to it is not the impersonal option. Every gift carries a written message, and those messages are usually the part the birthday person re-reads.

How to keep it fair across several grandchildren

The fairest approach most Australian families settle on is a set amount per age, applied to every grandchild in turn — not a set amount per year, and not an amount that drifts up as your circumstances change.

The trap is easy to fall into. The eldest grandchild gets $200 for their 18th in a good year; four years later the second grandchild's 18th arrives during a tighter stretch and gets $100. Nobody says anything. Everybody notices.

Three approaches that work:

1. The age ladder. Decide once: $50 under five, $75 for primary school, $100 for teens, $250 for 18ths and 21sts. Write it down. Apply it to everyone.
2. The flat rate. Everyone gets the same amount every birthday regardless of age, with milestones as the only exception. Simple, transparent, impossible to argue with.
3. The pooled milestone. Ordinary birthdays get something small; you save the real money for the big ones and give it meaningfully.

If there's a blended family in the picture, the default that causes the least friction is to treat step-grandchildren exactly as you treat the others. It's noticed, and it's remembered.

Sending money to a grandchild interstate? See how an online birthday gift page works — the family shares one link, you give from your phone, and your message arrives with the gift.

Cash, card or transfer — how grandparents birthday money actually arrives

Cash in a card is still the most common way Australian grandparents give birthday money, but it's no longer the most practical one — particularly when the party is in another city.

Here's how the options compare in real life:

That last option is what PocketWell does. A parent or grandparent creates a personalised page for the birthday, shares it by link or QR-code activation — a printed code on the invitation that guests scan with their phone camera — and guests give with Apple Pay, Google Pay or a card, leaving a message alongside the gift.

For the family running it, the mechanics are worth knowing: it's free for hosts, who receive 100% of the gift amount. Guests cover a 3.5% platform fee plus standard payment processing, shown clearly before payment. Payouts go out weekly on Tuesdays through 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. You can read the full fees and payouts detail in the FAQ.

Across the birthday pages we see, the median event collects gifts from about seven guests and totals around $800 — which is usually the difference between "a nice pile of cards" and "the thing they actually wanted".

What to check before you give a larger amount

If you receive an Age Pension or another income-support payment, larger gifts can affect it — so it's worth a quick check before you hand over a substantial sum.

Services Australia applies gifting limits to money and assets given away, and amounts above those limits can still be counted in your assets and income tests for a period afterward. The thresholds are set by government and change from time to time, so check the current figures directly on the Services Australia gifting page rather than relying on what a friend told you at bowls. This isn't financial advice — it's just the one piece of admin that catches grandparents out most often.

Two other things worth a thought:

• Tell the parents if it's a large amount. Not to ask permission, but so it doesn't arrive as a surprise they have to manage — especially if siblings are watching.
• Say what it's for, if you have a preference. "This is for the savings account" or "this one's yours to blow" removes all the ambiguity. Grandchildren appreciate being told which kind it is.

If you'd like to point the money somewhere useful rather than somewhere fun, the Australian Securities and Investments Commission's Moneysmart has plain-English guidance on savings accounts for kids that's worth a read before you open one.

What to write in the card

The message is the part that lasts, whether it's handwritten or typed into a gift page. Short and specific beats long and general every time.

A few that work at any age:

• "Happy birthday. Put this toward something you've had your eye on — and tell us what you pick."
• "Ten already. We're very proud of you. Love from Nan and Pop."
• "Twenty-one. Spend some, save some, and ring your grandmother."
• "This is for the savings account, but we've popped something extra in for you to actually enjoy."
• "We're sorry to miss the party from Perth. Blow out a candle for us."

If you're writing for a milestone, one specific memory is worth more than three lines of sentiment. Name the thing — the year they learned to swim, the way they used to mispronounce your name.

For families setting up a page and stuck on the wording, our birthday wishing well wording guide has templates that don't sound like a request for money.

Frequently asked questions

Q: How much should a grandparent give a grandchild for their birthday?

A: Between $50 and $200 covers most Australian grandparents, with $100 the most common single amount. Across the birthday gift pages run through PocketWell, the median gift is $100 and roughly eight in ten sit inside that $50–$200 band. Adjust down without guilt if you have several grandchildren — six grandkids at $100 each adds up quickly, and families with larger broods routinely give less per child. Adjust up for milestones like a 1st, 18th or 21st, where doubling your usual amount is the norm. The one thing worth keeping steady is consistency between grandchildren at the same age.

Q: Is money a good birthday gift for a young grandchild?

A: Yes, and it's more common than most people assume. For children under five, the money is realistically for the parents to direct — into a savings account, an education fund, or toward something larger the child needs. Our data shows no drop-off in gift size for this age group: the median birthday gift for children aged five and under is still $100. The usual approach is money plus one small present the child can unwrap on the day, so there's something to open. Our first birthday gift guide covers that first milestone in more detail.

Q: Should I give each grandchild the same amount?

A: Most families find an age-based ladder works better than a flat rule — the same amount for each grandchild when they reach the same age, rather than the same amount to everyone in the same year. That way a five-year-old and a nineteen-year-old aren't receiving identical gifts, but no child ends up receiving less at eighteen than their older sibling did. Write the ladder down somewhere. The unfairness that causes friction is almost never deliberate; it's the slow drift that happens when you decide fresh each time.

Q: How much should grandparents give for an 18th or 21st birthday?

A: $100 to $500 is the usual range for these two milestones, and grandparents often give the largest single gift of the day. $200 is a comfortable middle. If several relatives are contributing toward one goal — a car, a trip, a first rental bond — pooling into a single larger amount tends to be more useful than separate gifts. Pooled milestone gifts are common at both ages, and it's worth knowing roughly what other guests are giving so your amount sits where you want it to.

Q: Does giving money to grandchildren affect my Age Pension?

A: It can. Services Australia applies gifting limits to money and assets you give away, and amounts over those limits may still be assessed in your income and assets tests for a set period. The thresholds are set by government and change periodically, so check the current figures on the Services Australia gifting page before giving a large sum. This is general information rather than financial advice — if the amount is significant, a quick conversation with a financial information service officer is worth the phone call.

Q: Is it rude to send birthday money by transfer instead of a card?

A: Not at all, particularly for teenagers and adult grandchildren who'd rather have the money in their account than in a drawer. The only thing a bare transfer misses is the message — so send a text, a card, or a note alongside it. If the family has set up an online gift page, your message travels with the gift automatically, which is why interstate grandparents often prefer it. Either way, the amount matters less than the fact that you remembered and said something personal.

Q: What if I can't afford much this year?

A: Give what you can and say something meaningful in the card. A $20 gift with a specific, warm note is a genuinely good gift, and no reasonable family thinks otherwise. If you're feeling the squeeze across several grandchildren, consider shifting to a pooled model: something small on ordinary birthdays, and saving your capacity for the milestones where a larger gift makes a real difference. Many families also find that offering time — a day out, a weekend stay, help with driving lessons — lands better than money the child will have spent by Friday.

Q: How do online birthday gift pages work for grandparents who aren't tech-savvy?

A: You don't need an account, an app or a password. The family shares a link or a QR code, you tap it, choose an amount, pay with Apple Pay, Google Pay or your card, and type a message — the whole thing takes about a minute on a phone. Guests cover a 3.5% platform fee plus standard processing, shown before you confirm, and the host pays nothing. If you'd rather see the mechanics first, the host's page explains fees, payouts and security in plain terms before you confirm anything.

Final thoughts

There is no correct amount to give a grandchild for their birthday — but $100 is the number most Australian grandparents land on, and $50 to $200 is the band almost everyone sits inside.

The three things worth getting right: keep it consistent between grandchildren at the same age, step it up for the milestones, and always write something in the card. The money gets spent. The message doesn't.

And if the family is organising something bigger — a first birthday, an 18th, a pooled gift toward one goal — contributing to a shared page isn't the lazy option. It's often how the grandchild ends up with the thing they actually wanted, plus a page of messages from everyone who chipped in.
