Maturity Amount for Recurring Deposits

Hi!

I want to find the formula for getting the Maturity Amount for a recurring deposit.

My bank debits my account for $100 every month and I have this arrangement for 12 months then what would be my Maturity amount?

I know the Interest rate - 3% p.a compounded quarterly.

How can I get the total amount alongwith the interest for periodic payments for a given period?

for example I am paying $100/- per month for 12 months and the bank is offering interest rate of 3% per annum.

What amount i would get from the bank at the end of 12th month?

I need the simple formula.
Analogy :
Like Profit = Selling Price - Cost Price.

and then something in Excel...
