Minimum pot to sustain Phase 1 income to age 90, using your dual-pot settings.
2) Retirement income
Dual-pot strategy
At retirement, 1 year's income is moved from your growth pot (volatile) into a stable income pot (lower %). Each year the income pot is topped up from the growth pot. If the growth pot can't cover the top-up, it draws from income pot reserves and a shortfall is flagged.
