A limit on how much the interest rate or the monthly payment can change, either at each adjustment or during the life of the mortgage. Payment caps don't limit the amount of interest the lender is earning, so they may cause negative amortization.

A limit in how much an adjustable rate mortgage's monthly payment or interest rate can increase. A cap is meant to protect the borrower from large increases and may be a payment cap, an interest cap, a life-of-loan cap or an annual cap. A payment cap is a limit on the monthly payment. An interest cap is a limit on the amount of the interest rate. A life-of-loan cap restricts the amount the interest rate can increase over the entire term of the loan. An annual cap limits the amount the interest rate can increase over a twelve-month period.
