Assumptions and limitations
Interest-only payments do not reduce principal. The remaining balance is repaid over the shorter remaining term after IO ends. Both entered rates are assumptions, not live offers; rates, fees and offsets are held constant. A negative extra-interest result means the entered IO rate is sufficiently lower to offset its longer outstanding balance.
