When we think about helping our children financially, education and first homes usually top the list. Retirement often feels decades away, especially for teenagers or even young adults. Yet the truth is, the earlier your children—or grandchildren—start saving, the easier and more secure their later years can be. Encouraging long-term saving is not just about money; it’s about habits, mindset, and peace of mind for the whole family.
Start Conversations Early—And Keep Them Age-Appropriate
Talking to teenagers about money might feel awkward, but it doesn’t have to be complicated. You can start with simple concepts: “Part of what we earn now, we save so we have more choices later.” As children grow, you can introduce ideas like retirement accounts, compounding interest, and workplace superannuation plans in ways that feel relevant to their lives.
Conversations with adult children often take a different shape. Rather than teaching basic concepts, you may be encouraging action: “It’s never too late to start, even small contributions now can make a big difference.”
With grandchildren, the approach can be playful and illustrative, like comparing savings to planting a tree: small seeds now grow into strong, lasting results.
Lead by Example
Children and young adults notice habits more than words. Parents who regularly contribute to KiwiSaver or other retirement accounts demonstrate saving isn’t just “for later”—it’s a normal part of adult life. Grandparents can also model behaviour by sharing their own experiences or even helping set up their grandchildren’s first savings accounts, making the process tangible and meaningful.
Illustrate the Power of Time—And Compound Interest
Compound interest is the superpower of long-term savings. Even a modest weekly contribution can grow significantly over decades. Use real-life examples to show the difference between starting at 18 versus 30—or even 50. Interactive tools or calculators can be helpful, especially for adult children who may have avoided retirement planning: seeing numbers grow makes the benefits concrete.
Start Small, Make It Consistent
For teens, even $10 a week adds up. For adult children, the focus may be on regular contributions, no matter the size. For grandchildren, consider matching small contributions to show how saving early pays off. The key across all ages is consistency: small, steady contributions often beat sporadic large ones. Celebrating milestones—like reaching the first $1,000 in a fund—reinforces positive habits.
Involve the Whole Family
Saving for retirement doesn’t have to be a solitary task. Families can make it collaborative: parents and children tracking goals together, grandparents sharing stories of financial lessons learned, or even playful “growth challenges” where each member sees their savings increase. This approach makes the abstract idea of long-term saving more tangible and creates a culture of financial literacy across generations.
Teach Smart Budgeting and Prioritisation
Encourage teens and young adults to divide their income into spending, short-term saving, and long-term saving. Adult children may need more nuanced guidance in balancing retirement contributions with other life priorities, such as mortgages, raising children, or paying off debt. It’s common for adults in their 30s and 40s to feel they “can’t afford” to save for retirement while managing these competing demands—but small, consistent contributions can still make a big difference over time.
One approach is to help them create a clear budget identifying essential expenses, short-term goals, and long-term priorities. Show them how even a modest percentage of their income dedicated to retirement can grow significantly over the decades due to compounding interest. Suggest practical strategies, such as:
-
Automating contributions: Setting up automatic transfers to a retirement account ensures saving happens without constant decision-making, making it easier to “pay themselves first.”
-
Incremental increases: If immediate contributions feel impossible, advise starting small and gradually increasing the amount each year, perhaps coinciding with pay rises or bonuses.
-
Balancing debt repayment and retirement: Help them assess high-interest debt separately from long-term savings. Paying off expensive debt first can free up more room for future retirement contributions, while still keeping retirement on the radar.
-
Prioritizing long-term security: Frame retirement contributions as an essential part of financial health, not an optional extra. Adults often underestimate the future cost of living and healthcare needs—small sacrifices now can prevent major stress later.
-
Flexible goal-setting: Encourage them to set realistic, adjustable targets. Even if a mortgage or childcare expenses limit contributions, knowing there’s a plan—and that it can grow over time—reduces the feeling of being “behind.”
Grandparents can support this process subtly by emphasising the emotional and practical benefits of prioritising retirement savings: independence, reduced stress in later life, and the freedom to make life choices without being constrained by financial pressures. Sharing examples from personal experience—such as the difference it made to start saving at 30 versus 40—can make the message relatable and motivating.
By approaching retirement saving as part of a broader life strategy, adult children can find a balance that respects immediate responsibilities while steadily building security for the future.
Highlight Benefits Beyond the Numbers
Retirement savings aren’t just about wealth—they’re about security, freedom, and peace of mind. Teens can understand saving now gives them more options later, while adult children may appreciate the reassurance it offers in avoiding financial stress. Grandchildren can learn early that planning ahead means choices, not constraints, in adulthood.
Use Stories and Real-Life Examples
Storytelling resonates across generations. Share examples of people who started late and struggled, and those who began early and enjoyed financial freedom. Stories make abstract consequences concrete and relatable, whether your audience is a teen, a young adult, or a grandchild just learning about money.
Celebrate Progress, Not Perfection
Financial habits develop over time. Encourage family members to celebrate even small wins, like opening a savings account or making the first contribution to a retirement fund. Reinforce that setbacks are normal, but persistence and awareness build lifelong habits.
Whether you’re a parent in your 50s guiding a teenager, a parent in your 60s helping adult children take charge of their finances, or a grandparent nurturing your grandchildren’s money smarts, it’s never too early—or too late—to encourage saving for retirement. By starting conversations, modelling behaviour, making saving achievable, and framing it as a tool for freedom and security, you can instil habits that last a lifetime. Your guidance today can be the difference between financial stress and peace of mind for generations to come.
