The total interest would be 73606.07 dollars, approx.
In two years, the value of 10,000 dollars with 3.78 interest would be 10,770.29 dollars. An increase 770.29 dollars would be realized.
At six percent, you would make about $6000.
You would need 9687 dollars.
12000 per year is 20 percent of 60000
Assuming simple interest, just multiply 2000 dollars x (6/100) x 5. For compound interest, the formula is a bit more complicated. You would get some more interest in the case of compound interest.
No if the account earns interest daily, it's earning interest on interest essentially. So if you have $100 and you earn 1% interest, you would have $101 dollars the next day and earn 1.01 dollars in interest, and so on.
If compounded and assuming the amount was 3180 dollars, it would be 784 dollars.
