# What is the difference between future value of cash and Fixed deposit calculator [closed]

suppose my present value of cash is 2,22,051 and its future value is calculated by using the formula FV=PV(1+r)^n with r=8 and n=3.So future value is 12,95,001.432

Now if I go to fixed deposit calculator and tried calculating future value of present cash 2,22,051 with interest 8.5% and period of 36 months then it is 285,783.77.

so why there is huge difference between these two?

• `fixed deposit calculator` Which calculator are you talking about ?? Did you use r as 0.08 or used 8 ?? Compunding for 36 months is very different from compounding for 3 years. You calculate interest on interest earned for 36 months. – DumbCoder Mar 31 '14 at 11:01
