ANNUAL CAP

A clause within an adjustable-rate mortgage (ARM) contract which puts limitation on the possible increase in the interest rate of the loan to a specific amount every year. The cap is often specified in terms of rate, but the dollar amount of the interest and principal payment may also be capped as well. The annual caps are created to secure borrowers from an abrupt and excessive increase in the price of the their monthly payment during the times when rates rise intensely over a short span of time.
