How to talk to your partner about retirement planning.

Retirement planning is, on paper, one of the most important financial conversations a couple can have. In practice, many couples either avoid it entirely, or leave it to whichever partner is more financially engaged — which means one person is planning for two, often without a clear picture of what the other person actually wants. Often, neither partner has yet found their personal retirement number.

The result is that many couples arrive at retirement having never genuinely aligned on what they want that chapter of their lives to look like, what it will cost, or whether their savings are on track to fund it.

This conversation doesn't have to be difficult. But it does need to happen.

Why couples avoid it

There are a few common reasons this conversation gets deferred.

One partner may feel less financially confident than the other and reluctant to engage with numbers they don't fully understand. One may be more optimistic — or more anxious — about retirement than the other, and sense that the conversation might surface a disagreement they'd rather not have. And for many couples, money is simply a topic that carries more emotional weight than practical ones, making it easier to leave for another day that never quite arrives.

None of these are unusual. But they all have a cost — because the earlier couples develop a shared picture of their retirement, the more time they have to do something about it.

Start with what you want, not what you have

The most effective way to begin the retirement conversation isn't with numbers — it's with vision. Before either partner looks at a savings balance or a projected retirement figure, it's worth spending some time on a simpler and more personal question: what do we actually want retirement to look like?

This question tends to be more engaging and less threatening than a financial one, and the answers often reveal assumptions that have never been made explicit. One partner may be imagining an active retirement full of travel; the other may be picturing something quieter and more local. One may assume you'll stay in your current home; the other may have been quietly thinking about downsizing. One may want to retire as early as possible; the other may find meaning in work and have no particular desire to stop.

None of these differences are problems in themselves — but they are much better discovered in a conversation than after the fact. And the vision that emerges from an honest discussion tends to be richer and more genuinely shared than anything either partner would have arrived at alone.

Then look at the numbers together

Once there's a shared sense of what retirement should look like, the financial picture becomes much more purposeful to examine. What will the lifestyle you've described actually cost? What are you each currently on track to accumulate? Is there a gap — and if so, what does closing it require?

ThatDay is designed to make this conversation easier. Is KiwiSaver enough to retire on? is a good starting point for couples who want to understand the building blocks before working through the full plan. As a free retirement planning platform built for New Zealanders, ThatDay calculates retirement needs and savings projections for couples as well as individuals — accounting for both KiwiSaver balances, any retirement age you choose, and the spending level you decide on together. Working through ThatDay as a couple, rather than one partner doing it alone, tends to produce a much more genuinely shared plan.

A few things worth covering

Beyond the big picture, there are some specific topics that are worth raising explicitly in a couples retirement conversation.

Individual savings. KiwiSaver balances are individual assets. It's worth both partners knowing what each has accumulated — and why women in particular benefit from knowing their own number explores this further. Assuming a combined figure that neither has actually verified is a common and avoidable oversight.

Different retirement ages. If partners are different ages, or have different ideas about when they want to stop working, the plan needs to account for a period where one is retired and the other isn't. This is more common than people realise and worth thinking through explicitly.

What happens if circumstances change. Separation, illness, or the death of a partner all affect retirement in ways that are uncomfortable to discuss but important to have considered. A plan that only works if everything goes as expected is a fragile one.

Spending now. If one partner spends more freely than the other, retirement planning conversations sometimes surface that difference in a productive way for the first time. Arriving at a shared view of what your spending actually reflects — what genuinely adds to your life together and what doesn't — is one of the most valuable things a couple can do, both for their retirement and for their relationship with money more broadly.

The spending conversation within the retirement conversation

This last point is worth dwelling on, because it connects to something deeper than retirement planning. Many couples have never had an explicit conversation about what their spending actually represents — which parts of it reflect genuine shared values and which are habitual, unconsidered, or driven by social comparison.

When that conversation happens, it can be genuinely clarifying. Couples who arrive at a shared sense of what "enough" looks like — what level of spending provides everything they genuinely need for a happy and fulfilling life — often find that both their retirement prospects and their day-to-day financial relationship improve. They're not just saving more. They're spending in a way that reflects what they actually care about, together.
