Lets say , I opened a MOD (100000/-)in SBI on Jan 1 , 2013 for 1 year.

I withdrawn 50000/- on 28 of march 2013(after 3 months).
I withdrawn 30000/- on 30 of june 2013(after 6 months).
I withdrawn 20000/- on 30 of september 2013(after 9 months).

Amount in first 3 month , 100000/-
Amount in 4-6 months, 50000/-
Amount in 7-9 months,20000/-
Amount in 10-12 months,0/-

How will they calculate interest for this premature MOD? When will the interest credited back to my Savings account(only after one year from the date of joining or after 9 months or after each transaction from MOD account)?
