How to Teach Your Kids About Money at Every Age

Money Skills by Age, Starting from Three

You can start teaching your children about money from around age three, beginning with coins and simple choices, then building saving and spending habits through primary school, and introducing earning, tax, and compound growth in their teens. In our experience advising New Zealand families, the parents who raise financially capable children share one trait: they treat money as a normal household topic rather than something to discuss once their children are "old enough."

Research from Dr Ashley LeBaron-Black at Brigham Young University's Financial Socialisation Lab, published in the Journal of Financial Planning (2018), finds that parental intentionality matters more than expertise. Talking about money, practising with it, and making financial decisions visible within family life has a measurable effect on children's adult financial capability, regardless of the parents' own level of knowledge. Most parents who search for this kind of guidance already have the one thing that matters: willingness to start. The cost of raising children in New Zealand means substantial money already flows through your household, and that money is itself a teaching tool. Planning your family finances and teaching your children about money are two sides of the same conversation.

Parents Are the Primary Influence

Financial capability is being progressively embedded into the New Zealand school curriculum through a national curriculum refresh, within the Social Sciences and Mathematics learning areas. Coverage varies significantly by school. Some use dedicated platforms like Banqer, a New Zealand-developed classroom economy simulation. Many do not.

The 2024 ANZ Financial Wellbeing Report found only 31% of New Zealanders scored highly on financial knowledge questions. Financial literacy in New Zealand remains uneven, and whatever schools deliver, children learn money habits primarily by watching the adults around them. A study by Whitebread and Bingham (2013), commissioned by the UK Money Advice Service, found that children's money habits are largely formed by age seven. The window for shaping those habits opens earlier than most parents expect.

Ages 3 to 5: Coins, Choices, and Waiting

Core concepts

At this age, children can grasp three ideas: money is exchanged for things, some things are needs and others are wants, and saving means waiting for something you want.

What to do

• Let them handle physical coins and notes. Name the denominations. Count together.
• Play shop at home. Use real coins or play money and take turns being the buyer and seller. This makes the connection between money and goods tangible.
• At the supermarket, give them a simple choice: "We can get the cereal or the yoghurt, but not both today." This introduces opportunity cost without naming it.
• Use a clear jar instead of a piggy bank. Watching coins accumulate makes saving concrete and visual. This single jar becomes the foundation for the three-jar system in the next stage.

A NZ-specific first step

Open a youth savings account. All major New Zealand banks offer fee-free children's accounts from birth: ASB Headstart, ANZ Go Account, Westpac Bump, BNZ YoungSaver, and Kiwibank Free Up are among them. Even if the balance stays small, your child grows up knowing they have a bank account with real money in it.

Ages 6 to 12: Building Real Habits

This is the stage where most parents start searching for guidance, and it is the most consequential window. Your child can now manage small amounts of real money, understand trade-offs, and begin connecting effort to reward.

Core concepts

Earning, budgeting a small amount, saving toward a goal, giving, and the basics of how prices work.

The three-jar system

Upgrade the single savings jar from the preschool years to three containers labelled Spend, Save, and Share. When your child receives pocket money or birthday money, they divide it across all three. The ratio matters less than the habit. On $10 per week, a 50/30/20 split means $5 for spending, $3 toward a savings goal, and $2 set aside for giving. Let your child have input on the ratio. The Share jar introduces generosity as a core part of financial life, not an afterthought.

Making money visible in a cashless world

Most transactions your child observes are contactless or digital. Money disappears without being seen. Physical cash in jars, counting coins at the kitchen table, and walking through a bank statement together counterbalance this. When you tap your card, say what you are spending and roughly how much. The goal is to make invisible transactions visible again.

Pocket money and earning

The allowance debate generates strong opinions. Some parents prefer a fixed weekly amount to give children regular practice managing money. Others tie payments to household contributions, reinforcing the connection between effort and income. Both approaches work. The factor research highlights as most important is regularity: children need a predictable, recurring flow of money they are responsible for allocating. If you want to explore the case for tying pocket money to specific tasks, there is a detailed argument for commissions over allowance worth reading.

For benchmarking, the 2023 ASB Kiwi Pocket Money Survey found the average was approximately $5 to $10 per week for primary school-aged children. Adjust to your household; the amount matters less than the consistency.

Activities that work at this age

• Set a savings goal together (a toy, a book, a day out) and track progress visually on the fridge.
• At the shops, ask them to compare two similar products and explain which is better value and why.
• Match their savings contributions dollar-for-dollar toward a goal. This teaches the concept of earning a return on saving, which mirrors the employer contributions they will encounter when they eventually join a KiwiSaver Scheme.
• Involve them in a small part of the household budget: let them plan the grocery list for one meal within a set amount.

NZ-specific tools

Check whether your child's school uses Banqer, a New Zealand classroom platform that simulates earning, tax, saving, insurance, and investing. If they do, ask your child what they are learning and extend those conversations at home. If they do not, Sorted.org.nz (run by the Retirement Commission) offers free resources designed for parents and children.

This is also the age to consider enrolling your child in a KiwiSaver Scheme. Children can join from birth. There are no employer contributions and no annual government member tax credit until your child earns income and contributes from wages, but voluntary family contributions grow over time. Even modest, regular top-ups across a decade or more create a meaningful head start. The compound growth section later in this piece shows how large that head start can become.

Ages 13 to 18: Real Money, Real Decisions

Core concepts

Budgeting earned income, understanding debit and credit, recognising marketing pressure (including from social media finfluencers), and grasping the basics of compound growth.

What changes at this age

Teenagers typically access an EFTPOS or debit card from around age 13 (the exact age varies by bank). The shift from physical cash to a card is a critical teaching moment: money becomes invisible, and spending can feel frictionless. Talk about this explicitly. Show them how to check their transaction history and set up notifications for purchases.

When your teenager starts part-time work, three things happen at once: they earn real income, they become subject to PAYE tax, and if they are enrolled in a KiwiSaver Scheme, employer contributions and the government member tax credit begin. This is the single best opportunity to teach them about tax, compounding, and the principle of paying yourself first. Walk through their first payslip line by line. Show them gross pay, the PAYE deduction, their KiwiSaver Scheme employee contribution, and the net amount that reaches their bank account. If they have a second job, explain why the tax rate on that income is higher (the secondary tax code applies a flat rate to prevent under-deduction across multiple employers) and how they can get any overpayment back through an end-of-year income tax assessment with IRD.

Practical exercises

Give them a real expense to budget. A monthly clothing or phone credit budget forces trade-offs. If they overspend in week one, they feel the consequences in week four. This is experiential learning no lecture can replicate.

Introduce them to compound growth using their own KiwiSaver Scheme balance or savings account. Show them what their balance could look like at age 30, 40, and 65 if they keep contributing. The worked example below is designed for exactly this conversation.

The finfluencer conversation

Teenagers absorb financial content from social media, much of it sponsored and some of it misleading. Discussing how to evaluate financial claims, who profits from a recommendation, and why "get rich quick" content persists is now a necessary part of financial education at home.

Ages 18 and Beyond: Launching Well

By 18, the foundational habits should be in place. The focus shifts to execution.

First, KiwiSaver Scheme contribution rates. Most young workers default to the 3.5% minimum (rising to 4% on 1 April 2028), but understanding how a higher rate now affects both their take-home pay and their long-term balance is worth discussing before they set and forget. If they plan to buy a first home, their KiwiSaver Scheme balance will form part of their deposit through the first home withdrawal provision, so early contribution decisions have property implications too. For parents in a position to help financially, the bank of mum and dad conversation is easier when your child already understands deposits, savings, and the workings of a KiwiSaver Scheme.

Second, student loans. Repayments are deducted automatically at 12% of income above the annual repayment threshold set by IRD (for the 2026 tax year, this is $24,128; check the IRD student loans page for the current figure). Many graduates do not realise this is happening until they see their first full-time payslip. Walking your child through the mechanics before they start work removes the surprise.

Third, an emergency fund. Even a small buffer of $1,000 to $2,000 in an accessible savings account reduces the chance that an unexpected cost leads to high-interest debt. This is the habit that separates young adults who absorb financial shocks from those who spiral into borrowing.

Sorted.org.nz offers free budgeting and retirement projection tools that make a useful starting point for anyone building their first adult financial plan.

Starting Later Than You Planned

If your child is already a teenager and none of the earlier steps happened, you have not missed the window. You have missed the easiest window. The 13–18 years are when children can absorb the most complex concepts, and a teenager who starts managing real money today will still build stronger habits than one who never practises at all. Open a bank account together this week, walk through a payslip, and start the three-jar system even if it feels late. The research from LeBaron-Black is clear: starting the conversation at any age is measurably better than not starting it.

The Compound Growth Conversation

If you teach your child one financial concept with numbers attached, make it this one.

Imagine investing $20 per week on behalf of your child in a diversified growth fund. The figures below assume a net return of 5% per year after fees and after tax at the 28% prescribed investor rate (PIR), which is the rate most adult earners pay on PIE fund returns including most KiwiSaver Schemes. Children without taxable income have a lower PIR (currently 10.5%), which would produce slightly higher net returns in the early years, but the examples below use 28% throughout to keep the illustration conservative. A 5% net return is reasonable for a growth-oriented fund over long periods, though actual returns will vary year to year and are not guaranteed.

1. ‍Starting at birth: By age 65, total contributions of roughly $67,600 could grow to approximately $475,000.‍
2. Starting at age 18: Total contributions of roughly $48,900 could grow to approximately $185,000 by age 65.‍
3. Starting at age 30: Total contributions of roughly $36,400 could grow to approximately $94,000 by age 65.

The difference between starting at birth and starting at 30 is roughly $381,000, on about $31,000 of additional contributions. That gap is almost entirely explained by the additional years of compounding. This is the number worth writing on a whiteboard with your teenager.

One important caveat: many young New Zealanders withdraw part or all of their KiwiSaver Scheme balance to buy a first home, which resets the compounding clock on whatever is withdrawn. The first home withdrawal provision is valuable, but it means the age-65 figures above assume the money stays invested for the full period. If your child withdraws at 30 for a house deposit, the post-withdrawal balance starts compounding again from a lower base. That trade-off is worth discussing as a family.

These are illustrations rather than forecasts. Investment returns, fees, inflation, and tax rates will all affect the actual outcome. But the directional lesson holds: time is the most powerful variable in investing, and it is the one resource your children have in abundance. Understanding this concept early is part of building what some families think of as generational wealth: not a single inheritance, but a set of habits and knowledge passed from one generation to the next.

Lead by Example

LeBaron-Black's research describes financial behaviour as "more caught than taught." Four specific habits make the biggest difference.

Budget visibly. You do not need to share your salary with a seven-year-old. But letting your children see you compare prices, plan a holiday within a budget, or decide to wait before making a purchase normalises deliberate financial decision-making.

Talk about trade-offs. When you choose a less expensive option, say why. "We're going with this one because it does everything we need, and the extra money can go toward the trip" teaches more than any worksheet.

Show them your KiwiSaver Scheme annual statement. Once a year, sit down with your child and walk through what goes in, what the return was, and what the balance is tracking toward. This makes retirement saving real and normal, not abstract.

Be honest about mistakes. If you overspent on something or made a financial decision you regret, age-appropriate honesty about it teaches resilience and normalises imperfection. The goal is not to model flawless money management. It is to model thoughtful money management.

Common Questions

Should I let my child make financial mistakes?

Within safe limits, yes. A child who spends their entire savings on something they quickly regret learns a lesson about impulse buying that no conversation can replicate. The stakes are low now; the lessons compound.

What if we are starting late?

A 14-year-old who begins managing real money today still has four years of practice before adulthood. Open a bank account, introduce the three-jar system, and walk through a payslip together. The compound growth numbers are smaller with a later start, but the habits and decision-making skills are not diminished by starting in the teenage years. See the "Starting Later Than You Planned" section above for specific steps.

Where to Start This Week

Pick one action from the list below, matched to your child's age, and do it before the weekend.

• Ages 3–5: Buy a clear jar. Put it on the kitchen bench. Start dropping coins in together.
• Ages 6–12: Set up the three-jar system and agree on a weekly pocket money amount, even if it is $5.
• Ages 13–18: Sit down with your teenager's bank app or latest payslip and walk through every line together.

Small, early actions tend to produce outsized results over time. Starting imperfectly beats waiting.
