accrued interest

Hi, experts
I have a question about interest.
my contract have the following cash flow:
the date of payment interest – 15.03.2014

1. 10.01.2014 Disbursement   10,000.00
2. 13.02.2014   Disbursement    3,000.00
   20.02.2014   Disbursement    5,000.00
   05.03.2014   Disbursement    6,000.00

Interest rate (variable rate)
10.01.2014 – 1%, Interest accruals since 10.01.2014 to 15.03.2014, base amount  - 10,000.00
13.02.2014 – 1.5%, Interest accruals since 13.02.2014 to 15.03.2014, base amount  - 3,000.00
20.02.2014 – 1.8%, Interest accruals since 20.02.2014 to 15.03.2014, base amount  - 5,000.00
05.03.2014 – 2%, Interest accruals since 05.03.2014 to 15.03.2014, base amount  - 6,000.00

The cahs flow is now calculate

Interest rate (variable rate)
10.01.2014 – 1%, Interest accruals since 10.01.2014 to 12.02.2014, base amount  - 10,000.00
