Terms and Conditions

1. This calculator uses ATB's conventional mortgage rates and does not correctly calculate the prepayment amount on mortgages insured by CMHC, Sagen, or Canada Guaranty. Contact ATB at 1-800-332-8383 or your nearest ATB branch for assistance with these mortgages.

   ATB's current mortgage interest rates may change without notice. The estimated IRD depends on the current mortgage interest rate when the estimate is obtained and will change on the payout date if ATB's mortgage interest rates have changed.
