Frequently Asked Questions – Best Early Retirement Calculator (FIRE) 2025
What is this FIRE calculator used for?
Our early retirement calculator (FIRE calculator) helps you determine when you can retire early based on your savings rate, expenses, and investment returns. Unlike traditional retirement calculators, this fire calculator calculates your retirement age by determining when your savings will reach your FIRE number. Use this best early retirement calculator to answer "when can I retire" and plan your path to financial independence retire early.
How accurate are the FIRE calculator projections?
Our fire calculator provides estimates based on your inputs and proven FIRE methodology (25x rule). While we use established financial formulas, actual results will vary due to market fluctuations, changing savings patterns, and life circumstances. Use the results as planning guidelines for your fire retirement journey. The calculator is most accurate when you use realistic assumptions for returns and expenses when determining when can you retire.
What rate of return should I use for FIRE planning?
Most FIRE calculators use 7-8% for growth phase and 5-7% for early retirement phase. Conservative FIRE seekers should use 6-7% (accumulation) and 4-5% (retirement), while aggressive FIRE planners might use 8-10% and 6-8%. Historical stock market returns average around 10% annually, but FIRE planning requires longer timelines (40-50+ years). Use conservative estimates in our fire calculator to ensure your when can I retire projections are sustainable.
What is my FIRE number? How much do I need to retire early?
Your FIRE number is 25x your annual retirement expenses (based on the 4% withdrawal rule). For example, if you need $40,000/year, your FIRE number is $1 million. For more conservative early retirement, use 28-30x expenses (3.5% withdrawal rate). Our fire number calculator determines this automatically. Your specific number depends on desired lifestyle, whether you'll have other income sources, and your risk tolerance. Use our financial independence number calculator to get personalized FIRE targets.
What is the 4% rule for FIRE? Is it safe for early retirement?
The 4% rule is the foundation of FIRE calculations - it suggests you can safely withdraw 4% of your portfolio annually. With $1 million saved, that's $40,000/year. However, early retirement means 40-50+ year timelines vs traditional 30 years. Many FIRE adherents use 3.5% for extra safety. Our fire calculator uses 4% by default but allows you to adjust the withdrawal rate for more conservative early retirement planning.
Can I really retire in my 30s, 40s, or 50s with FIRE?
Yes! With the right savings rate and strategy, early retirement is very achievable. Saving 50-70% of income can lead to retirement in 10-15 years. Saving 30-40% typically means 20-25 years to FIRE. The key is starting early, maximizing your savings rate to retire early, and staying consistent. Our best early retirement calculator shows exactly when can you retire based on your specific situation. Use our retire at 40 calculator, retire at 50 calculator, or retire in 10 years calculator scenarios to explore your options.
Should I count on Social Security for FIRE planning?
Most FIRE calculators and financial independence planning ignore Social Security entirely for early retirement. If you retire at 40-50, you can't access Social Security until 62-67 anyway. Consider it a bonus safety net for later years, but don't factor it into your FIRE number calculation. Our fire calculator focuses on investment portfolio only, ensuring you can truly retire early without depending on government programs.
What if I'm starting FIRE late? Can I still retire early?
Yes! Even starting at 35-40, you can achieve early retirement by 50-55 with aggressive savings. Focus on maximizing your savings rate to retire early - even increasing from 20% to 40% can cut years off your timeline. Consider Barista FIRE or Coast FIRE strategies if full early retirement seems far off. Use our when can I retire calculator to see how increasing savings rate, reducing expenses, or working a few extra years impacts when will I retire. Starting now is better than waiting!
How often should I check my FIRE progress?
Review your FIRE plan quarterly or monthly to stay motivated. Run the fire calculator after major life changes like job switches, salary increases, expense changes, or hitting savings milestones. Many FIRE adherents track their progress obsessively - it helps maintain focus and adjust course when needed. Use our when will I retire calculator regularly to see how you're tracking toward financial independence retire early. Celebrate milestones like reaching 25%, 50%, and 75% of your FIRE number!
How do I calculate my savings rate for FIRE?
Calculate savings rate by dividing annual savings by gross income. For FIRE, aim for 30%+ (standard FIRE), 50%+ (aggressive FIRE), or 60-70%+ (extreme FIRE). Higher savings rates have double benefit: you accumulate money faster AND need less since you're living on less. Our fire calculator automatically determines when can you retire based on your savings rate. Focus on increasing this rate - it's more impactful than investment returns for achieving financial independence retire early.
