🔍 How This Calculator Works
Our probability model uses statistical factors based on real billionaire data:
- Base probability (0.001%): The statistical likelihood for an average UK adult
- Wealth multiplier: Each £1M in current wealth increases odds proportionally (most billionaires had £1M+ by 30)
- Income multiplier: Higher income enables faster wealth accumulation through savings and investments
- Age factor: Younger individuals have more time for compound growth and business building

📈 The Math of Becoming a Billionaire
To reach £1B by age 65, you need to:
- Save £100,000/month and earn 7% returns starting at 25 → £1.2B
- Build a company worth £1B (typically requires 60-80% equity)
- Inherit £500M and double it (but only 30% of billionaires inherited)
🎯 Factors That Actually Matter
Real-world billionaire studies show these factors are crucial:
- Risk tolerance: Most billionaires took significant calculated risks
- Business ownership: 85% of self-made billionaires own a business
- Timing: Being in the right industry at the right time (tech boom, etc.)
- Network: Connections to capital and mentors
- Education: 60% have university degrees (but 40% don't)
