Margin and Credit Interest Calculations:
Interest charges and credits are calculated on the net daily debit or credit balance in your account. Interest incurred and interest earned will be posted monthly to your account and is calculated on a 360-day year.
The applicable interest period is from the first day of each month to the last. Any free credit balances will be offset against any debit in the margin account, and interest will be charged on the net debit balance, if any.


Account value: $10,000
Margin Interest rate: 7.95% APR
Transaction: $20,000 of XYZ purchased on 1/01 and sold on 1/15

  1. Take the amount of money borrowed and multiply it by the interest rate:
    10,000 * .0795 = 795
  2. Take the product and divide it by the number of days in the year:
    795 / 360 = 2.21
  3. Multiply this result by the number of days XYZ was held on margin:
    2.21 * 15 = 33.15

It would cost $33.15 to borrow $10,000 for 15 days.

1. These funds are only available to residents of the state listed in the fund name.
