The Critical Decade

Your 40s are the pivot point for retirement planning. You're far enough along to have accumulated something, but you still have 20+ years of earning ahead.

This is when most people either get serious about retirement—or realize they need to.

The Math of Starting at 40

If you start saving seriously at 40 with 25 years until retirement at 65:

Monthly savings of €500 (at 6% return):

  • Final value: ~€350,000

Monthly savings of €1,000:

  • Final value: ~€700,000

Monthly savings of €1,500:

  • Final value: ~€1,050,000

The numbers are achievable—but they require commitment.

Where You Should Be at 40

Traditional benchmarks suggest 3x your annual salary by 40. More practically:

  • Minimum: €100,000-€150,000 in retirement accounts
  • On track: €200,000-€300,000
  • Ahead: €400,000+

But remember: what matters is your expenses, not your income.

The Catch-Up Strategies

1. Maximize Pension Tax Relief

In Ireland, you can claim tax relief on pension contributions based on age:

  • Under 30: 15% of income
  • 30-39: 20% of income
  • 40-49: 25% of income
  • 50-54: 30% of income
  • 55-59: 35% of income
  • 60+: 40% of income

At 40-49, you can contribute 25% of your income with tax relief. On a €60,000 salary, that's €15,000/year—and €6,000+ in tax savings.

2. Lifestyle Creep Check

Your 40s often bring higher income. The question: where's it going?

Common lifestyle creep traps:

  • Bigger house (bigger mortgage)
  • Private school fees
  • New cars every 3-4 years
  • Holiday upgrades

Every €500/month in lifestyle creep is €175,000 less at retirement.

3. Clear High-Interest Debt

Credit cards at 20%+ APR are retirement killers. Pay these off before increasing pension contributions beyond employer match.

4. Review Your Investment Mix

At 40, you have 25+ years until retirement. You can still afford to:

  • Hold higher equity allocations (70-80%)
  • Weather market volatility
  • Benefit from long-term compound growth

Being too conservative now means missing growth when you need it most.

The Mortgage Question

Should you pay off your mortgage early or invest more?

Pay off the mortgage if:

  • Your mortgage rate is high (4%+)
  • You value the certainty of being debt-free
  • You struggle to invest while having debt

Invest more if:

  • Your mortgage rate is low (2-3%)
  • You're comfortable with debt
  • You want to maximize compound growth

There's no wrong answer—but you need to choose one and commit.
