He has a house for 200 million won
When I invested 2 million won every month

For average returns of 4%, 8%, 12%, 16%, 20%

How much will it be in 20 years

It’s 1.1 billion, 2 billion, 3.6 billion, 6.6 billion, 12.1 billion.

How long will it be after 30 years?

It’s 2 billion, 4.7 billion, 11.8 billion, 29.9 billion, 75.8 billion.

If you invest in stocks, you vaguely think that you have to go over at least 10%.
If you look at the numbers above, you’ll see that it’s impossible.

I believe that the appropriate average annual return is around 4% at the current 2-3% deposit rate in commercial banks,

Excluding various taxes, management costs, and medical insurance premiums, I think it will be a success if there is about 2% of net profit left.

Please raise the return beyond that from your business income.

Don’t think about increasing the yield, and extend the compound period by another 10 years.
You can start investing five years early, and work five more years.
