## Quick answer

Index funds passively track a market and charge less — often 0.05–0.25% OCF. Active funds employ managers to beat the market and charge more — typically 0.5–1.0%+. Most active funds underperform their benchmark over 10+ years after fees.

The index vs active debate is really about fees and odds. For long-term ISA and pension investors, low-cost global index trackers are the default starting point — active funds need a clear reason to justify higher cost.

## Key facts

- Global index trackers often charge 0.1–0.25% OCF vs 0.75–1.0%+ for active equivalents
- SPIVA data shows majority of active UK equity funds underperform indices over 10 years
- Index funds reduce single-manager risk and style drift
- Active may suit niche areas some investors accept higher fees for — use sparingly

## How index funds work

They replicate an index (FTSE All-Share, global MSCI World, etc.) by holding the same shares or a representative sample. No manager bets on stock picks — costs stay low.

## When active funds get considered

Some investors use active funds for specialist sectors (e.g. smaller companies, ESG screens) or trust structures with gearing. Even then, compare after-fee performance over full market cycles.

## Frequently asked questions

### Are index funds safer?

They have lower specific manager risk but still carry full market risk — prices fall in downturns. Diversification and time horizon matter more than active vs passive label.
