In my jujitsu (Goshin Jujitsu) we are graded every three months so bearing the belt system in mind:
White, Yellow, Orange, Green, Blue, Brown 1st Stripe, Brown 2nd Stripe, Brown 3rd Stripe, Black, Black 1st Dan-10th Dan.
I'd say about 18 months (1 year and 6 months).

I have been doing jujitsu for several years and it takes about 3-4 years to become a blue belt
