Early Retirement Extreme Review for UK Readers
Jacob Fisker retired in his early 30s on roughly £5,500 a year. The maths needs an 80% savings rate, which sounds insane until you read his case for it.
Savings rate vs years to financial independence
Years to FI from zero, 5% real return. The savings rate is the only lever that bends the curve this hard.
ERE in the UK: what helps and what hurts
| Factor | UK reality |
|---|---|
| NHS healthcare | Helps - no insurance premium needed |
| Average rent outside London | Hurts - over £1,000 per month |
| Rent a Room scheme | Helps - up to £7,500 tax-free per year |
| Full-time nursery | Hurts - over £14,000 per year per child |
| ISA allowance | Helps - £20,000 per year tax-free |
| SIPP access age | Hurts - locked until 57 from April 2028 |
Fisker target: live on £7k-8k per year. UK housing is the binding constraint.
Key takeaways
Early Retirement Extreme advocates for financial independence through radical lifestyle changes and reduced expenses, rather than increased income.
The book emphasizes the importance of developing diverse skills to reduce dependency on paid services, which lowers living costs.
Fisker's approach focuses on interconnected financial systems, suggesting that treating your financial life holistically is key to achieving early retirement.
To achieve five years of financial independence, Fisker's method requires saving 80% of your income, but housing costs in the UK pose significant challenges to this plan.
