For example, we’ll take Promissory note.

**PN ** Promissory note nominal value

**E ** Eskont the amount of interest

**ES ** Eskont sum (sum of Promissory note for the amount of eskont)

**IK ** Interest key (the numerical value which is obtained for 360 days a year and the eskont rate)

**IN** Interest No. is 100

We take one year, days of the year, 360 days.

**TP ** The time period of maturity promissory notes

**Formula for calculating Eskont loan**

**E=PNxTPxES / 360xIN**
