How much cash buffer do I need?
Short answer:
A cash buffer is money held in cash or cash‑like investments to cover near‑term spending, so you’re less likely to sell growth assets after a market fall. How much depends on your spending, how stable your other income is, and how comfortable you are with volatility. Instead of a single ‘right’ number, think in timeframes: what you need soon, what can wait, and what can stay invested for longer.
Key takeaways
Buffers are about choice: spending without forced selling
The right size depends on spending, income stability and comfort with volatility
Timeframe thinking can be clearer than chasing one ‘best’ number
Revisit your buffer after large withdrawals or big market moves
Keep it simple so it’s easy to maintain
Why this matters
A buffer can reduce stress in down markets, because you’re not making rushed decisions. It also supports a more consistent lifestyle, which is often the real goal in retirement.
Mini-plan (3-4 steps)
- List your next 12 months of expected spending, including lumpy costs.
- Decide which expenses must be paid regardless of markets, and which can be deferred.
- Set a buffer approach based on timeframes (near-term vs longer-term) rather than one rigid rule.
- Review the buffer after large expenses, market shocks, or changes to other income.
