How much money should I lock up in my savings account?
Lets imagine two scenarios: 1) You make 10.4k (40% of total income) yearly contributions to a savings account that earns 1% interest for 10 years. In this scenario, you put in 104k and earned 5.89k in interest, for a total of 109.9k. 2) You make the same 10.4k yearly contribution to an index fund that earns 7% on average for 10 years. In this scenario you put in the same 104k, but earned 49.7k in interest*, for a total of 153.7k. The main advantage is option 1) has more liquidity -- you can get the money out faster. Option 2) requires time to divest any stocks / bonds. So you need enough savings to get you through that divestment period. Imagine another two scenarios where you stop earning income: 1-b) You stop working and have only your 109.9k principal amount in a 1% savings account. If you withdraw 15.6k yearly for your current cost of living, you will run through your savings in 7 years. 2-b) You stop working and have only 20k (2 years of savings) in savings that earns 1% with 153.7k in stocks that earns 7%. If you withdraw your cost of living currently at 15.6k, you will run through your investments in 15 years and your savings in 2 years, for a total of 17 years. The two years of income in savings is extremely generous for how long it starts the divestment process.  In summary, invest your money. It wasn't specified what currency we are talking about, but you can easily find access to an investment company no matter where you are in the world. Keep a small amount for a rainy day.
