Your public servant wife seems to have sufficient service - by retirement- to qualify for the max pension. However it probably depends on the particular scheme, but if she has max service ( circa 45 years) I would suggest hat she will have very limited scope for AVC's.
As for you, a total contribution of 13% is reasonable at this stage. But you should look up the Pensions Board calculator to check what 13% p.a will likely provide. It will not provide maximum benefits, but remember that based on your salary you need to remember that there is a max fund of €2.3m currently (though hopefully that might increase by the time you retire).
Could I also suggest that you think about the death in service benefits. What would be the financial impact in the event of either of you dying prematurely? Also what about the financial impact of disability and being unable to work?
