A : the Total P : the amount you started with i : interest rate as a decimal (5÷100= 0.05) n : the investment period in years A= P(1+i.n) A= 2000(1+(0.05×8)) A= 2800
It is 8%
Assuming that the 10 % stated is per year, the investment will earn 0.10 X 20000 = 2000 per year. The years required to earn 4000 will be 4000/2000 = 2.
about how many years would it take for $1000 to become $2000 with an interest rate of 7.2
To calculate compound interest: final_value = (1 + rate/100)periods x amount So for amount = 2000, at a rate = 6% per year over a period of 35 years you get: final_value = (1 + 6/100)35 x 2000 = 1.0635 x 2000 ~= 15372.17
Multiply the principal (P) by the annual* interest rate as a decimal (r) and the time in years* (t). *The time period may be expressed in months, etc. For example, $2000 invested at 7% simple interest for 5 years: I = Prt = 2000x0.07x5 = 140x5 = $700.
It is 240 currency units.
It earns 431.0125 . After 4 years, it has grown to 2,431.01 .
The interest rate would end up being 9% after you do all the calculations.

Each quarter, you are going to make Interest rate/number of periods per year on your investment. Since you have an interest rate of 8% and four periods per year, each quarter you make 2% on your principal. Thus, the formula for determining the value of your investment after ONE quarter is Principal * 102% or P*1.02. Each time you accrue interest, your investment grows by a further 2%, so the formula for the value of your investment over x quarters is P*(1.02^x) (the carrot "^" is a common computer symbol denoting an exponent). Since you are interested in 8 years and you have 4 quarters per year, you will have 32 compounding periods and a final formula of P*(1.02^32). Since you don't know P, but do know the final value of $2000, you must solve the following equation for P. P*(1.02^32)=2000 To do this, simply divide both sides by 1.02^32. This gives you the value of your initial principal: P = 2000/(1.02^32)
