Why multiple value to time calculator need?
Generally we hear that how much time will take to double money with the interest rate of r. Then how to know what time will take so we need some calculations or any calculator.
What is the multiple value to time calculator formula?
a= Multiple value
r= yearly CAGR return in %
time in years, t
a=(1+0.01*r)^t
loge(a)=loge(1+0.01*r)^t
loge(a)=t*loge(1+0.01*r)
t= loge(a)/loge(1+0.01*r)
