Interface

InterestSecurity

Returns the interest rate for a fully invested security. The function works using the following equation: where:

• rate is the interest rate for the security,
• redemption is the amount to be received at maturity,
• investment is the amount invested in the security,
• B is the number of days in the year, depending on the year

basis,

• and DIM is the number of days from settlement to maturity.

Example 1

#include <iostream>
 
#include <codecogs/units/date/date.h>
#include <codecogs/units/date/dateymd.h>
#include <codecogs/finance/banking/interestsecurity.h>
 
int main(int argc, char *argv[])
{
  int settDate=Units::Date::date(1999, 2, 15);
  int maturityDate=Units::Date::date(1999, 5, 15);
 
  double intRate=Finance::Banking::interestSecurity(settDate, maturityDate, 1000000, 1014420,
Finance::Banking::yb_Act360);
 
  int y, m, d;
  Units::Date::dateYMD(settDate, y, m, d);
  printf("settlement=%i/%i/%i\n", y, m, d);
 
  Units::Date::dateYMD(maturityDate, y, m, d);
  printf("maturity=%i/%i/%i\n", y, m, d);
 
  printf("interest rate=%f", intRate);
  return 1;
}

Output:

settlement=1999/2/15
maturity=1999/5/15
interest rate=0.058328
