An interest-only mortgage calculator shows monthly payments during the interest-only period and the significantly higher payments once amortization begins. During the interest-only phase, no principal is reduced. When the loan converts to fully-amortizing, payments jump 30–50% to pay off the same balance in the remaining term.
