Dep Calculaton

Hi

I want to know how the system is calulating Dep on following Details

Dep Method is NBV

Rate is 5%

Porate Convention and Divide Dep is by Days

Cost is 983985.83

DPIS=01-Apr-09

Current periid is Apr13

From 01-Apr-09 till Mar 13=1461 days

therefor 983985.83*5%/366*1461 days=196931.96

but the system shows===182523.21

Dep for Apr=on NBV= (983985.83-196931.96)=787053.87*5%/366*30=3234.46

but the system shows ==3293.68

Let me know what logic the system is calulating the Dep in above case and why there is a difference.
