Earned interest income

If you're talking simple interest at a fixed rate, then 200,000 x 5% = 10,000

It depends whether the 5% means 5% per annum or 5% per month. If it is per annum, this means that you would need much more than $200 000 in your bank account to earn $10 000 a month. Indeed with $200 000 in your bank account at a 5% per annum rate of interest you would earn $10 000 a year. This also assumes that you are saving into a tax free account.

In order to earn $10 000 interest per month you would need to earn $120 000 interest in 12 months. By having $2 400 000 in your bank account you will accumulate $120 000 interest in 12 months, and $10 000 interest per month. This also assumes that your bank account is tax free savings.

You would need to deposit $2,400,000 into that account with a fixed rate of 5% per year to earn $10,000 a month from it, which is $120,000 per year.

In order to generate a monthly income of $10,000.00 from your money account (this is before paying taxes) you must deposit $2,400,000.00. Taxes to be paid would be about $1900.00 @ 19%, so your net income would be about $8100.00. For a monthly income of $10,000.00 (after paying taxes) you would have to deposit $2,975,000.00 in your money account. Your Gross Income would be $12,395.83, taxes would be about $2355.20 @ 19%. Your Net Income would be $10,040.63.
