A clause stipulated in the contract of an adjustable-rate mortgage (ARM) that limits the possible increase in the loan's interest rate to a certain amount each year. The cap is usually defined in terms of rate, but the dollar amount of the principal and interest payment can be capped as well. Annual caps are designed to protect borrowers against a sudden and excessive increase in the amount of their monthly payments when rates rise sharply over a short period of time.

No definition available.
