How long will a £2,000,000 pension pot last — the very-high-net-worth retirement.

A £2 million pension produces £80,000/year at the 4% safe withdrawal rate — comfortably above the PLSA 'comfortable' retirement standard of £43,100/year. At this scale the question of pot longevity is essentially solved; the interesting questions are entirely about tax and estate planning. The £268,275 lump sum allowance caps your tax-free cash at around 13% of the pot rather than the headline 25%. The remaining £1.73m+ is subject to income tax when drawn. Pension assets generally sit outside your estate for inheritance tax purposes (subject to scheme rules and the 75-year-old threshold), so the optimal strategy often involves drawing other assets first and using the pension as an IHT-efficient wealth transfer vehicle. This is firmly into territory where you should be working with an experienced FCA-regulated wealth manager.
