annual interest rate of 8.5% compounded monthly ?

campbell_st · Answer

will using the formula 

$$A =P(1 +\frac{ r}{100})^n$$

and the number of periods = 12 x 5 = 60

and interest rate r = 8.5/12

$$2000= P(1 + \frac{8.5 \div 12}{100})^{60}$$

now solve for P

okay i get how to solve it now..but i get 1.007 i highly dobut its right can you recheck it for me?

campbell_st · Answer

the monthly interest rate is 0.070833% or 0.00070833

so $$P = \frac{20000}{(1.00070833)^{60}}$$
