How this calculator works

This Australian FIRE calculator uses FY2024-25 tax rates and rules to project your path to financial independence. Unlike simple calculators that only use the 25x rule, our model accounts for the unique aspects of Australia's financial system.

Australian tax calculations included

• Income tax: FY2024-25 tax brackets ($0-$18,200 at 0%, $18,201-$45,000 at 19%, $45,001-$135,000 at 32.5%, $135,001-$190,000 at 37%, $190,001+ at 45%)
• Medicare levy: 2% on taxable income above the $26,000 threshold
• HECS-HELP repayments: Calculated using the 2024-25 repayment thresholds and rates (1%-10% based on income)
• Division 293 tax: Additional 15% super contributions tax for income above $250,000

Superannuation modelling

The calculator projects your super balance separately from other investments because super can't be accessed until preservation age (60 for most Australians). This is critical for FIRE planning as you need sufficient assets outside super to bridge the gap between your target retirement age and when you can access your super.

• Super Guarantee (SG): Currently 11.5% of ordinary time earnings, increasing to 12% by 2025
• Concessional cap: $30,000 per financial year (employer + salary sacrifice)
• Super tax: 15% on contributions (accumulation phase)
• Preservation age: 60 for those born after 1 July 1964

Common FIRE questions for Australians

What is the FIRE movement?

FIRE (Financial Independence, Retire Early) is a lifestyle movement focused on aggressive saving and investing to achieve financial independence much earlier than traditional retirement age. The goal is to accumulate enough wealth that investment returns can cover your living expenses indefinitely.

How do I calculate my FIRE number?

Your FIRE number is typically 25 times your annual expenses (based on the 4% safe withdrawal rate). For example, if you spend $60,000 per year, your FIRE number is $1.5 million. In Australia, you also need to consider superannuation preservation age rules - you can't access super until age 60, so you need enough outside super to bridge the gap.

How does superannuation affect FIRE in Australia?

Superannuation is a powerful tool for FIRE, but it's locked until preservation age (60 for most). This means you need two buckets: investments outside super to fund early retirement (e.g., retiring at 45-55), and super to fund traditional retirement (60+). The tax advantages of super make it excellent for the second phase.

What savings rate do I need for FIRE?

Your savings rate determines how quickly you can reach FIRE. At a 50% savings rate, you can retire in roughly 17 years. At 70%, it drops to about 8.5 years. Most FIRE aspirants aim for 50-70% savings rates, though any increase in your savings rate accelerates your timeline.

Is the 4% rule still valid in Australia?

The 4% rule (withdraw 4% of your portfolio annually) was based on US historical data. For Australian investors, it remains a reasonable guideline, though some argue for a more conservative 3.5% rate for longer retirements (40+ years). Factors like franking credits and the age pension can actually improve outcomes for Australian retirees.

How much do I need to retire at 50 in Australia?

To retire at 50, you need enough investments outside super to cover 10 years of expenses until you can access super at 60. If your expenses are $60,000/year, you'd need approximately $600,000-$700,000 outside super, plus a healthy super balance for age 60 onwards. This calculator models both phases for you.

Key factors that impact your FIRE timeline

• Savings rate: The single biggest factor - higher savings rate means faster FIRE
• Investment returns: Long-term returns of 7-8% are typical for diversified portfolios
• Expenses: Lower expenses mean a lower FIRE number and faster accumulation
• Income growth: Increasing income while maintaining expenses accelerates savings
• Tax efficiency: Using super, franking credits, and tax-effective structures
