CorkscrewRxOλ() multiplies a rate times the opening in a corkscrew calculation. This example is a simple consumer loan (accrual method = 30/360) at 5% APR for 6 months. The CorkscrewRxOλ() function multiplies the opening balance by the rate divided by 12 months per year to calculate interest charges. The function adds the opening, interest charges and payments (negative) to calculate the closing. NOTE! Payments are the Payment amount multiplied by the Effective array.
