What is an emergency fund?
An emergency fund is a cash reserve specifically set aside to cover unexpected expenses or financial emergencies. It serves as your financial safety net, protecting you from having to sell investments or go into debt when life throws you a curveball.
Why you need an emergency fund
Protects your investments
Prevents you from selling index funds during market downturns to cover unexpected expenses, allowing your investments to recover and grow.
Avoids debt
Eliminates the need to use credit cards or take loans for emergencies, saving you from high-interest debt that can derail your financial goals.
Provides peace of mind
Reduces financial stress and allows you to take appropriate investment risks knowing you have a safety net.
Maintains cash flow
Keeps your monthly budget intact during temporary income disruptions like job loss or reduced hours.
How much should you save?
| Target | Who it suits |
|---|---|
| 3-6 months of expenses | Standard recommendation for most people with stable employment |
| 6-12 months of expenses | Self-employed, commission-based, or irregular income |
| 1-3 months of expenses | Very stable job with multiple income sources (minimum recommendation) |

Common emergency fund mistakes
Investing emergency money
Never invest your emergency fund in stocks or index funds. You need reliable access to this money.
Using it for non-emergencies
Maintain discipline and only use the fund for true emergencies to preserve your financial safety net.
Not replenishing after use
Always rebuild your emergency fund immediately after using it, before resuming index fund investments.
Once the fund is in place, you can move on to choosing your first index fund and model your contributions with the calculator.
