In the example shown, the formula in D5 is: At the outer level, the DATE function simply reassembles the component values back into a valid Excel date. To add years to the date, we just need to add the value in C5 to the year component prior to reassembly: The formula is then solved like this: Note: if you need to add an “even” multiple of 12 months to a date (i.e. 12, 24, 36, 48, etc) you can use a much simpler formula based on the EDATE function. See: add months to a date.
