Personal finance, from zero Lesson 58 / 60

Sofia at 28: the 37-year plan

Full worked example. Starting point, PAC, glide path, expected retirement. The plan that ties everything in the course together.

57 lessons of theory. Today we apply it to one person. Sofia, 28, from Milan. Her full financial plan for the next 37 years. Not an “optimization problem” — a realistic plan a human being can follow.

Starting state (2026)

  • Age: 28.
  • Job: Data analyst, Milan. €35,000 RAL (gross). ~€1,946/month net.
  • Relationship: single, no dependents.
  • Living situation: rents 35 m² in Navigli, €950/month.
  • Savings: €12,000 in conto corrente doing nothing.
  • Investments: zero.
  • Debt: none.
  • Pension: 4 years of INPS contributions from her first job.

Stage 1: Foundations (age 28-30)

Emergency fund

Target: 6 months × €1,385 essential expenses = €8,310.

Move €8,500 from conto corrente to a conto deposito at 3.0-3.5% gross.

Start investing

Remaining €3,500 from initial savings → global equity ETF (Vanguard FTSE All-World).

Set up monthly PAC

€500/month split:

  • €400 to global equity ETF.
  • €100 to EUR bond ETF.

Total stage 1 savings rate: ~26% of net income.

Start fondo pensione

Open Arca Previdenza (fondo aperto, ISC ~0.9%).

Personal contribution: €200/month = €2,400/year. Under €5,164 cap, fully deductible from IRPEF.

At 23% marginal rate: saves €552/year in IRPEF.

Also: redirect TFR to the fondo pensione. Employer contributes nothing extra (her employer doesn’t have matching), but TFR grows at market rate instead of INPS revaluation.

Stage 2: Building momentum (age 30-35)

Expected scenario: promotion to senior data analyst. New salary €42,000 RAL by age 32. Some raises after.

Increased savings capacity

Net income: ~€2,250/month.

New PAC: €700/month (keeping 30% savings rate).

Expanding the portfolio

Continue global equity ETF + EUR bond ETF. Maybe add:

  • Small-cap or emerging markets tilt (5% of equity).
  • Increase bond allocation as more cash comes in.

Personal life changes

Potential marriage / cohabitation. Dual-income household math becomes relevant. Shared expenses potentially reducing per-person cost of living.

If moving in with partner: reassess housing. Maybe buy together if stable.

Fondo pensione adjustment

At salary €42k, marginal rate 35%. Max €5,164/year contribution now saves €1,807 in IRPEF.

Contribute the max. This is the highest-ROI retirement decision she’ll make.

Stage 3: House decision (age 33-40)

The buy-vs-rent question

Sofia considers buying a 60 m² apartment in outer Milan. Price: €280,000.

  • Down payment needed (20%): €56,000.
  • Mutuo: €224,000 over 25 years at 3.5% fixed = ~€1,120/month.
  • Plus €100/month condo + €50/month IMU (if not prima casa) or €0 (prima casa).
  • Plus €50/month maintenance + €20 insurance.
  • Total monthly housing cost: ~€1,290.

Compare to rent: ~€950-1,000/month in her current area.

Breakeven: buying is slightly more expensive monthly but builds equity over 25 years. Over 30 years, owning typically beats renting by a lot. See /tools/buy-vs-rent/ for the calculator.

Impact on investing

If she buys: down payment of €56,000 drains savings. Portfolio reduced.

But:

  • She now has a €280,000 asset (albeit illiquid).
  • Her housing cost is fixed rather than rising.
  • After 25 years, mutuo paid off; housing cost drops to condo+maintenance.

Over 30 years, owning vs renting typically adds €150,000-300,000 to net worth (depending on timing and market).

Decision: Sofia buys at age 35, after saving enough for down payment.

New PAC reduced to €500/month due to mutuo payment. Fondo pensione continues at max.

Stage 4: Career acceleration (age 35-45)

Assumption: Sofia’s career progresses. Lead data analyst role at 38, €55,000 RAL. Manager role at 42, €70,000 RAL.

Growing savings

Net monthly at €70k: ~€3,400.

Savings rate target: 30%+.

Monthly savings breakdown:

  • Mortgage principal: €500 (part of the €1,120/month).
  • Fondo pensione: €430/month (max €5,164/yr).
  • ETF PAC: €700-900/month.

Total: ~€1,600/month effective savings.

Portfolio rebalancing

As portfolio grows, she:

  • Keeps 75/20/5 target allocation.
  • Rebalances annually via contribution redirection.
  • Eventually (at €200k+), considers adding factor tilts or alternative assets.

Family considerations

If she has children: childcare costs, reduced income during parental leave. Savings rate may drop 10-20% for a few years.

Plan for this: build bigger buffer before starting family, accept temporary slowdown, resume aggressive saving as children enter school.

Stage 5: Mid-career consolidation (age 45-55)

Wealth milestone check

At 45 (17 years in):

  • Liquid portfolio: ~€200,000.
  • Fondo pensione: ~€120,000.
  • Home equity: ~€130,000 (house appreciation + mutuo paydown).
  • Total net worth: ~€450,000.

At 55 (27 years in):

  • Liquid: ~€450,000.
  • Fondo pensione: ~€260,000.
  • Home equity: ~€210,000 (house fully paid off at 60 via 25-year mutuo from 35).
  • Total net worth: ~€920,000.

Coast FIRE check

At 55 with €920,000 net worth, even stopping contributions would grow to ~€1,300,000 by 65 at 4% real. Plus INPS of maybe €22,000/year.

Sofia could work part-time or take a lower-stress role from 55 onward. Coast FIRE achieved at 55.

Shift toward stability

Gradually shift asset allocation to 60/35/5 (more bonds). Preserve gains.

Stage 6: Pre-retirement (age 55-65)

Optional semi-retirement

Sofia considers stepping back from full-time. Options:

  • Consulting/freelance 2-3 days/week.
  • Part-time employment.
  • Full retirement.

Financial math: she can draw 4% from portfolio (€37,000/year) but doesn’t need to if she’s earning any income.

Fondo pensione withdrawal planning

At 62 (5 years before INPS), she could use RITA to access fondo pensione early if needed.

Alternative: hold until 67, let fondo compound fully.

Decision: continues modest work (~€20,000/year earnings), no portfolio withdrawal yet.

Stage 7: Full retirement (age 65+)

Income streams

At 67 (full retirement):

  • INPS pension: €18,000-22,000/year depending on career path.
  • Fondo pensione: drawdown or lifetime annuity from ~€350,000 accumulated.
  • Liquid portfolio: €600,000+ continues compounding or provides 4% withdrawal.
  • House: owned outright, low housing costs.

Total retirement income: €35,000-50,000/year. Comfortable Regular FIRE lifestyle easily afforded.

Estate planning

In her 60s-70s: estate planning. Ensures smooth transfer to heirs (if any) or charitable giving (if not). Notary helps with will + designation of beneficiaries.

The sensitivities

Factors that could make it harder:

  1. Prolonged career gap. Each year out = significant lost compounding. Build buffer for this.
  2. Major health event. Insurance, emergency fund, mental flexibility.
  3. Economic regime change. Low returns decade reduces portfolio growth. Diversification helps.
  4. Divorce/split. Italy’s legal framework typically halves joint assets. Prenuptial less common than other jurisdictions.
  5. Industry disruption. Data analyst role may transform. Ongoing skills investment (lesson 15) mitigates.

Factors that could accelerate

  1. Bigger salary trajectory. Tech leads at €100k+ are common. Changes the math dramatically.
  2. Business ownership or equity. Startup success is rare but possible.
  3. Inheritance. Italian median inheritance at 55-65 is modest but non-zero.
  4. Real estate appreciation. Major cities have done well historically.
  5. No children. Dramatically reduces lifetime expenses and increases savings rate.

The key decisions, summarized

Across 37 years, Sofia makes maybe 50 significant financial decisions. Here’s what matters most:

  1. Emergency fund first (age 28-30). Protects everything else.
  2. Start PAC immediately (age 28). Time in market.
  3. Fondo pensione with max contribution from the moment job stabilizes (age 30+). Tax-advantaged retirement.
  4. Housing decision (age 33-38). Rent vs buy, when, where, how much.
  5. Career investments (lessons 13-18). Human capital compounds.
  6. Consistent asset allocation (age 28-60). Don’t tactical-trade.
  7. Tax optimization (lessons 41-46). Reduce drag.
  8. Behavioral discipline (lessons 53-57). Don’t panic-sell, don’t chase hype.
  9. Pre-retirement shift (age 55-60). Preserve gains, plan withdrawal.
  10. Full retirement (age 65+). Execute the plan.

The plan is simple

Actually, the plan isn’t complicated. It’s:

  • Earn steadily.
  • Save 25-30% of net.
  • Invest in global ETFs and fondo pensione.
  • Buy a home when it makes sense.
  • Stay invested through crashes.
  • Retire at 65ish with diversified income sources.

Complicated for hedge funds. Simple for retail.

The discipline is what’s hard. Saving consistently for 37 years requires many small-moment decisions to continue. Each decision is tiny; cumulative effect is huge.

What to do with this lesson

Three things:

  1. Write your own version of this plan. Your starting state, milestones, expected income trajectory.
  2. Identify the 3-5 key decisions that matter most in your life stage.
  3. Commit to the plan in writing. Revisit annually. Adjust for actual life, not for market noise.
