About This Calculator
Fat FIRE targets $100,000+ in annual retirement spending, typically requiring $2.5 million or more. It allows for international travel, private schooling, and premium healthcare without financial stress. High earners in technology and finance often achieve fat FIRE in their 40s by combining a $150,000–$200,000 savings rate with equity compensation like RSUs and ISOs.
