The Professional Bankroll: A 10-Year Simulation

## The Long-Run Vision One of the most valuable exercises for any serious bettor is running a 10-year projection of their operation — not as a promise of results, but as a structured way to think about what consistent, disciplined betting can produce. ## The Base Assumptions - Starting bankroll: £10,000 - Annual betting volume: £150,000 turnover (approximately £600/week staked) - Average edge (CLV): 3% - Annual staking method: 1.5% of bankroll per bet (proportional) ## The Year-by-Year Projection At 3% ROI on £150,000 annual turnover: expected annual profit = £4,500. Year 1: £10,000 → £14,500 (if proportional staking, slightly higher through compounding) Year 2: ~£19,800 Year 3: ~£26,000 Year 5: ~£41,000 Year 10: ~£97,000 Starting with £10,000 and consistent 3% edge: expected to approach £100,000 by year 10. ## The Variance Around This Projection Standard deviation of annual return at 3% ROI and typical variance: ~10% per year. 95% range for year 10 outcome: £40,000–£240,000 The wide range reflects cumulative variance over 10 years. The central estimate is £97,000; the realistic range is large. This is the nature of variance, not a flaw in the model. ## The Compounding Acceleration The most powerful phase of this 10-year projection is years 7–10. By this point, the bankroll has grown significantly, each 1.5% stake is a larger absolute amount, and the annual profit accelerates. Year 10 produces more absolute profit than years 1–3 combined. ## The Non-Financial Returns Beyond the financial projection, 10 years of professional betting produces: - A complete, audited performance record - A validated, mature statistical model - A network of professional contacts in betting and data analytics - Skills in probabilistic reasoning that have broad career applications - The psychological resilience that comes from operating under uncertainty for a decade These non-financial returns are not captured in the projection — but they are real and valuable.
