The Bridge Fund Strategy: How to Retire Before You Can Access Super

If you want to retire before 60 in Australia, you have a problem: your superannuation is locked until preservation age. You can't touch it early (with very limited exceptions). So how do early retirees fund the gap?

The answer is the bridge fund — a pool of investments outside super that covers your living expenses from the day you stop working until you can access super at 60.

How the Bridge Fund Works

Think of your retirement wealth as two buckets:

1. Bridge fund — accessible investments (ETFs, shares, bonds, cash, rental income) that fund your lifestyle from early retirement until age 60.
2. Superannuation — tax-advantaged retirement savings that fund your lifestyle from age 60 onwards.

If you plan to retire at 45 and preservation age is 60, you need a bridge fund that lasts 15 years. If you retire at 50, you need 10 years. The younger you retire, the larger your bridge fund needs to be.

How Much Do You Need?

The simplest estimate:

Annual Expenses x Years Until 60 = Minimum Bridge Fund

If you spend $60,000/year and want to retire at 45:

$60,000 x 15 = $900,000

But this is a conservative estimate because it assumes zero investment returns during drawdown. In reality, your bridge fund continues to earn returns while you draw it down, so you need less than the raw multiplication suggests.

A more realistic calculation uses a drawdown model that accounts for investment returns during the bridge period. Using a 5% real return assumption:

Estimates assume 5% real (after-inflation) investment returns during drawdown. Your actual number depends on asset allocation, sequence of returns, and spending patterns. Use our FIRE calculator for a precise projection.

What to Hold in Your Bridge Fund

Your bridge fund needs to balance growth with stability. You're drawing down from it, so a 40% market crash in year one of retirement is devastating if you're 100% in equities (this is called sequence of returns risk).

A common structure:

Years 1–3: Cash and Short-Term Bonds

Hold 2–3 years of expenses in cash or short-term bond ETFs. This is your buffer — if markets crash, you draw from this while equities recover. You never want to sell shares at the bottom to fund groceries.

• High-interest savings accounts
• Term deposits
• Short-duration bond ETFs (e.g. short-term government bonds)

Years 4–10: Balanced Mix

A mix of Australian and international shares with some bonds for stability.

• Australian shares ETF (e.g. broad market index)
• International shares ETF (e.g. global index, hedged or unhedged)
• Australian bond ETF for ballast

Years 10+: Growth-Oriented

Money you won't touch for 10+ years can be more aggressively invested since it has time to recover from downturns.

• International shares ETF
• Australian shares ETF
• Small allocation to emerging markets or small caps if desired

The Tax Advantage of the Bridge Fund

While super gets all the attention for tax efficiency, your bridge fund has its own advantages:

Capital gains discount. Assets held for more than 12 months receive a 50% CGT discount. If your marginal rate is 30%, you effectively pay 15% on long-term capital gains — the same rate as super contributions tax.

Tax-free threshold. In early retirement with no employment income, your first $18,200 of income is tax-free. Franked dividends come with franking credits that can push your effective tax rate to near zero.

Low-income offsets. The Low Income Tax Offset (LITO) and Low and Middle Income Tax Offset (LMITO, when available) can further reduce your tax in early retirement when your "income" is primarily from investment drawdowns.

Practical example: An early retiree drawing $60,000/year from their bridge fund (a mix of capital gains and dividends) might pay only $3,000–$5,000 in tax — an effective rate of 5–8%. This is because:

• Some drawdowns are return of capital (not taxable)
• Capital gains get the 50% discount
• Franking credits offset tax on dividends
• The tax-free threshold covers the first $18,200

Building Your Bridge Fund: The Accumulation Phase

If you're currently working and building toward FIRE, here's how to think about the bridge fund:

1. Max Out Super First (Usually)

This is counterintuitive — why put money in super if you can't access it until 60? Because the 15% contributions tax (vs your marginal rate of 30%+) means more money is invested and compounding. The maths usually favours maximising salary sacrifice even for early retirees, because your super bucket grows more efficiently.

The exception: if your bridge fund is significantly underfunded relative to your super, shift more to the bridge.

2. Invest the Rest in Low-Cost Index ETFs

After maxing super contributions, invest surplus income in a diversified portfolio of index ETFs in a standard brokerage account. This becomes your bridge fund.

Keep it simple. Two or three ETFs covering Australian shares, international shares, and optionally bonds is sufficient for most people.

3. Minimise Tax Drag During Accumulation

• Use ETFs that are tax-efficient (low turnover, minimal distributions)
• Consider accumulating ETFs (which reinvest dividends) vs distributing ETFs
• Hold for >12 months to get the CGT discount
• Use your partner's lower tax bracket if applicable

Common Bridge Fund Mistakes

Mistake 1: Ignoring sequence of returns risk. Retiring with 100% equities and no cash buffer is gambling. A 30% drawdown in year one of retirement, combined with regular withdrawals, can permanently impair your portfolio. Hold 2–3 years in cash/bonds.

Mistake 2: Being too conservative. The opposite mistake — holding everything in cash or term deposits. Over 15 years, inflation will erode your purchasing power. You need growth assets for the later years of the bridge.

Mistake 3: Not accounting for inflation. $60,000 in expenses today will be roughly $82,000 in 15 years at 2.5% inflation. Your bridge fund needs to account for rising costs, not just today's expenses.

Mistake 4: Forgetting about health insurance. If you leave employment, you may need to fund private health insurance yourself. Factor this into your bridge fund expenses.

Mistake 5: No plan for the transition. The day you hit 60 and can access super, your bridge fund and super need to work together. Plan the handover — you may want to consolidate, adjust your asset allocation, or start a pension stream from super.

Bridge Fund + Super: The Full Picture

The bridge fund isn't a standalone strategy — it works in concert with your superannuation. The ideal scenario:

1. Ages 30–45 (accumulation): Maximise salary sacrifice into super. Invest surplus income outside super into your bridge fund.
2. Ages 45–60 (bridge period): Draw from your bridge fund for living expenses. Super continues to compound untouched, growing tax-free inside the super environment.
3. Age 60+ (super drawdown): Switch to drawing from super. Earnings and withdrawals are tax-free. Any remaining bridge fund investments can continue to grow.

The beauty of this two-bucket approach is that your super has 15 extra years of untouched, tax-free compounding while you live off the bridge. By age 60, your super balance should be significantly larger than it would be if you'd started drawing at 45.

Model Your Bridge Fund

Every situation is different. Your bridge fund size depends on your expenses, risk tolerance, asset allocation, and how many years you need to bridge. Use our FIRE calculator to model both your bridge fund and super growth in parallel with your actual numbers.
