Interest calculation for crosses (CUR1/CUR2) 

Contract size (100,000 CUR1) x open buy or sell interest rate x no. of  lots
x 1 day (Friday 3 days) : 360 days  [result in CUR1]
 

Converted into US dollars by the BID rate USD/CUR1 or CUR1/USD at the time of rollover [for USD systems]

(for JPY system we would convert into Yen, ets…)

Examples:

Example calculation of premium buy at 0.5% for EUR/CHF for open 1 lot (EUR100,000) buy

100,000 x 0.5% x 1 x 1: 360      =    EUR 1.39.     EUR/USD at the time of rollover: BID 0.9800

Conversion into US dollars: 1.39 x  0.98=  USD1.36 

 

Example calculation of premium buy at 0.5% for CHF/JPY for open 1 lot (CHF100,000) buy

100,000 x 0.5% x 1 x 1: 360      =    CHF1.39.      

USD/CHF at the time of rollover: BID 1.7000

Conversion into US dollars: 1.39:  1.7000 =  USD 0.8
