Frequently asked questions

How many months should the emergency reserve be?
The general standard is 3-6 monthly monthly expenses. If you have a permanent and stable job, 3 month is enough, but if you are a freelancer, business owner or income uncertain, we recommend 6 month.
Where should the emergency reserve be kept?
It should be kept in easy-to-access and safe accounts, such as savings accounts that provide good interest, money market funds or short-term government bonds. It should not be kept in stocks because of volatility.
What if I'm out of the emergency reserve?
After you've spent your emergency reserves, you should quickly replenish them as a top priority before saving for other purposes, because reserves are a financial shield.
What should the monthly expenses in the calculation include?
Include all the essential expenses, like rent/loan, food, utilities, travel, minimum debt repayment and insurance. Not necessarily entertainment or shopping.
Disclaimer: The results are estimates. The appropriate number of months may vary depending on income stability and personal circumstances.
