Assuming the annual equivalent interest rate is 4.2%, it will take just over 81 months = 6 years + 9 months.

If the 5% is yearly, and it is compounded monthly, that means that the monthly interest rate is 5/12 percent. In this case, the base factor, in the formula for compound interest, is 1 + 5/1200. After one year (12 monthly periods), the capital would be 200000 x (1 + 5/1200)12. If you want to invest the money for two years (24 months), replace the exponent 12 by 24, etc.

If every six months the capital earn 10% interest which is compounded, at the end of 5 years, the interest will be 31875. If the annual interest rate is 10%, it makes no difference how often it is compounded. The six monthly interest rate is adjusted - to 4.88% rather than 5% - so that the total interest for a year is 10%.

If a sum of money was invested 36 months ago at 8% annual compounded monthly,and it amounts to $2,000 today, thenP x ( 1 + [ 2/3% ] )36 = 2,000P = 2,000 / ( 1 + [ 2/3% ] )36 = 1,574.51
