The decade-by-decade money map

Stage 3 · A year and beyond · Article 110 · Wave 2

---

If you've done the work of Articles 49 through 109, you have a stabilised post-separation financial life. The question becomes longer-arc: what does the next ten, twenty, thirty years look like financially. The decade-by-decade map isn't a plan in the usual sense. It's a rough shape of what each decade tends to need, what tends to happen, and what to attend to so the financial life keeps working as your life keeps changing.

This article covers what a decade map is for, the shape of each post-separation decade, the inflection points that change the map, when to redraw, and how to hold the map without making it rigid.

What the decade map is for

Most financial planning happens at one of two scales. Short, monthly budget, current year, immediate decisions. Long, retirement, end-of-life, multi-decade projections. The middle scale, decade-by-decade, often goes unattended.

The decade map fills the middle. It looks at what the next ten years tend to involve, what changes in the decade after that, and how the pieces fit together. It's not a prediction. It's a rough map of the terrain.

Three things the map is for.

1. Pacing your work. Different decades require different financial work. A 35-year-old separated parent and a 55-year-old separated parent have different priorities, different time horizons, different optimal moves. The map helps you do the right work at the right time.

2. Spotting the inflection points before they arrive. Children entering school, leaving school, going to university, becoming financially independent. Career peaks, possible reductions, possible second careers. Property transitions. Each of these has a financial dimension that benefits from being anticipated rather than absorbed in real time.

3. Avoiding decade-displacement of work. A common mistake is doing the financial work of the next decade in this one (over-saving when current life is suffering) or putting off the current decade's work to the next one (under-saving with vague plans to catch up later). The map clarifies what each decade actually requires.

The shape of each post-separation decade

The decade boundaries are rough. Use them as orientation, not as fixed lines.

Your 30s post-separation

Most parents who separate in their 30s have young children. The financial decade tends to be high-intensity.

What it usually involves:

• Highest child-related expenses (childcare, early education).
• Establishing post-separation financial independence.
• Building or rebuilding career trajectory.
• Lowest savings rate of any post-separation decade (so much is going to current expenses).
• High insurance needs (because so many people depend on you).

Priority moves:

• Stabilise income.
• Establish insurance properly (life, income protection).
• Whatever savings is possible, even modest amounts.
• Don't expect to be at high savings rates yet.

What to avoid:

• Lifestyle expansion that locks in expenses.
• Major financial decisions in the first 2-3 years post-separation.
• Over-saving at the expense of current quality of life. The children are young; this matters now.

Your 40s post-separation

Children are often older, school-age or teenage. Career is usually entering its higher-earning phase. Expenses may shift but rarely reduce.

What it usually involves:

• Children's education becoming expensive (especially private school, university preparation).
• Career often at higher income but also higher demands.
• Possibly a new relationship or partnership.
• The largest opportunity to substantially close any retirement gap.

Priority moves:

• Maximise retirement savings now. Time matters and there's still enough of it.
• Address career trajectory deliberately (training, network, possible specialisation).
• Be deliberate about any new relationship's financial integration.

What to avoid:

• Spending the income increases on lifestyle expansion rather than retirement.
• Inheriting your new partner's financial issues.
• Underestimating university costs.

Your 50s post-separation

Children are usually moving toward independence. Career may be at peak or approaching transition. Time horizon to retirement is now visible.

What it usually involves:

• Children leaving home; substantially reduced child-related expenses.
• Major asset decisions becoming relevant (downsizing the home, simplifying possessions).
• Career either continuing or starting to change shape.
• Retirement planning becoming concrete rather than abstract.

Priority moves:

• Recalibrate the housing question, does the home still fit.
• Increase retirement savings aggressively (this decade and the next are where most retirement gets built).
• Begin estate-planning conversations.
• Examine career sustainability through to planned retirement.

What to avoid:

• Lifestyle inflation as expenses decrease (the "I deserve this now" trap).
• Helping adult children financially in ways that compromise your own future.
• Inadequate retirement planning when retirement is becoming visible.

Your 60s post-separation

For most parents, this is the transition decade. Retirement either happens, gets pushed out, or restructures.

What it usually involves:

• The actual retirement decision and execution.
• Possibly health changes that affect work capacity.
• Children fully independent or close to it.
• Possibly grandchildren entering the picture.
• Income shift from earned to drawn.

Priority moves:

• Execute the retirement plan you've built.
• Adjust housing to retirement-appropriate (if you haven't).
• Establish the income strategy for retirement years.
• Maintain the social and physical infrastructure that supports a good retirement.

What to avoid:

• Hesitating to actually transition when you've reached the planned point.
• Over-supporting adult children at the expense of your own retirement.
• Underestimating healthcare and long-term care needs.

Your 70s and beyond post-separation

The map gets less detailed because individual situations vary widely. Some general considerations.

What it usually involves:

• Drawdown phase of retirement.
• Increasing healthcare needs.
• Possible inheritance planning becoming concrete.
• Possible support needs (yours, from children or care services).

Priority moves:

• Maintain a clear inheritance plan.
• Address long-term care provisions.
• Stay engaged with financial decisions (or designate clear authority for them).
• Maintain social infrastructure that prevents isolation.

What to avoid:

• Letting the financial life drift without attention.
• Avoiding conversations about your future care needs.
• Becoming financially isolated.

The inflection points that change the map

The decade map is a default. Specific events change it significantly. Five inflection points to watch for.

Inflection 1: Children's transition out

When children leave home and become financially independent, expenses can drop substantially. The savings rate that suddenly becomes possible should be deployed deliberately, not absorbed into lifestyle.

For most parents, the children-leaving-home moment is the largest single change in their financial trajectory. The decade after that transition is when retirement often gets substantially built.

Inflection 2: Major career shift

A new job, a promotion, starting a business, taking a sabbatical, accepting a reduction. Career shifts often reshape the financial map.

Major shifts deserve major attention. A new job at 25% higher income changes what's possible. A reduction at 25% lower income changes what's necessary. Don't absorb either silently; redo the map.

Inflection 3: Major relationship change

A new partner moving in. A long-term relationship ending. Marriage. Any of these significantly changes the financial picture in ways that need explicit reconsideration.

The map you had for life-as-one-person is different from the map for life-with-this-partner, and different again if that partner leaves.

Inflection 4: Property transitions

Buying or selling a home. Inheriting property. Downsizing. Property is usually the largest single asset class for most parents, so transitions in it reshape the whole map.

Plan property transitions deliberately. Don't make property decisions reactively when other things are also in flux.

Inflection 5: Health events

Significant illness, disability, accident, yours or a child's. These can reshape the map dramatically and aren't predictable.

The infrastructure to absorb health events, insurance, savings buffer, support network, should be maintained throughout. The events themselves can't be planned for specifically; the resilience to handle them can be.

When to redraw the map

Three triggers for redrawing.

1. Every five years as a default. Even without inflection points, the map deserves a redraw every five years. Life accumulates changes that aren't dramatic individually but add up. A five-year review catches the accumulation.

2. After any significant inflection point. The five points above (children's transition, career shift, relationship change, property transition, health event) each warrant a redraw within six months of the event.

3. When your sense of what you want has shifted. Sometimes the values themselves change. What you wanted from life at 35 isn't necessarily what you want at 45. When the values shift, the map needs to follow.

The redraw doesn't need to be elaborate. Two or three hours, with the spreadsheet from Article 49 and the projections from Article 108, is usually enough to update the map meaningfully.

How to hold the map without making it rigid

The risk with any long-arc plan is rigidity. Locking yourself into decisions made years before the moments they apply to. Five practices for holding the map lightly.

1. Treat the map as a working hypothesis

The map is what you currently think. It's not what must happen. As you live the years it describes, you'll learn things that change the map. Update it when you learn.

2. Don't make today's decisions only on the map's terms

If the map says you should be saving 20% but this year requires more spending on the children, this year wins. Don't sacrifice this year for an abstract plan. Make the adjustment, update the map, move on.

3. Pay attention to what you're not enjoying

If you're following the map but the financial life it's producing doesn't feel like a good life, the map is wrong. Financial plans serve actual lives, not the other way around. Adjust.

4. Build in slack

A map that depends on everything going right is fragile. Build in margin, a few percent extra savings, a year or two of extra working life as buffer, plans that work even if some elements don't. The slack is what lets the map survive contact with reality.

5. Don't share the map widely

Some financial plans are personal. The map you draw isn't necessarily for others to know about. Children don't need to know the projected retirement income. New partners don't need the full map for a long time. The privacy of the map is part of how it serves you.

What the decade map enables

When the map is in place, several things become possible that aren't otherwise.

1. Confident current decisions. You can make this year's financial choices knowing how they fit into the larger picture. The confidence comes from clarity about the longer arc.

2. Deliberate use of windfalls. Tax refunds, bonuses, inheritance, settlement adjustments, each has a clear destination in the map. The windfall doesn't get absorbed into lifestyle; it serves a specific purpose.

3. Reduced financial anxiety. The biggest source of financial anxiety is uncertainty about whether things will work out. The map doesn't make things certain; it does reduce uncertainty. The reduced uncertainty reduces the anxiety.

4. Better decisions about life shape. Career decisions, housing decisions, relationship decisions all have financial dimensions. The map clarifies what's possible and what isn't, which makes the non-financial decisions cleaner.

5. Generosity that doesn't compromise you. With the map in place, you know what you can give to children, friends, causes, future plans without compromising your own stability. Generosity becomes possible because it's bounded by knowledge.

Quick reference

What the decade map is for:

1. Pacing your work.
2. Spotting inflection points before they arrive.
3. Avoiding decade-displacement of financial work.

Shape of each post-separation decade:

• 30s: high intensity, lowest savings rate, stabilise and insure.
• 40s: maximise retirement savings, manage university costs, deliberate relationship integration.
• 50s: aggressive retirement saving, housing recalibration, estate planning starts.
• 60s: retirement transition, income shift to drawn, infrastructure for good retirement.
• 70s+: drawdown, healthcare, inheritance, social infrastructure.

Five inflection points that change the map:

1. Children's transition out (biggest single change).
2. Major career shift.
3. Major relationship change.
4. Property transitions.
5. Health events.

When to redraw:

• Every five years as default.
• After any inflection point.
• When values shift.

Five practices for holding the map lightly:

1. Treat it as working hypothesis.
2. Don't make today's decisions only on the map's terms.
3. Pay attention to what you're not enjoying.
4. Build in slack.
5. Don't share the map widely.

What the map enables:

• Confident current decisions.
• Deliberate use of windfalls.
• Reduced financial anxiety.
• Better decisions about life shape.
• Generosity that doesn't compromise you.

The map is rough. The map is yours. The map is what lets the next thirty years be financial-decisions-you-make, rather than financial-things-that-happen-to-you.
