Find out how soon you can retire early using the FIRE method. Calculate your target retirement number and track progress toward financial independence.
The FIRE movement (Financial Independence, Retire Early) has inspired millions to reconsider traditional retirement timelines. This calculator uses the 4% safe withdrawal rule and your savings rate to estimate how many years until you can retire — often decades earlier than the traditional age 65.
This early retirement calculator implements the FIRE (Financial Independence, Retire Early) methodology to determine when you can achieve financial independence and stop working for money. The calculator determines your FIRE number by multiplying your annual expenses by 25 (based on the 4% safe withdrawal rate), then calculates how long until your investment portfolio reaches that target given your current savings rate and expected returns. It demonstrates how increasing your savings rate dramatically reduces your working years, showing the exponential relationship between savings rate and time to freedom. The tool also accounts for the higher withdrawal rate risk inherent in early retirement, since you may need your portfolio to sustain 40-50+ years of withdrawals rather than the traditional 30-year retirement horizon.
Result: With $100,000 saved, $2,000/month contributions, $4,000/month expenses at 7% returns, your FIRE number is $1,200,000. At your current pace you would reach FIRE in approximately 18 years at age 53.
