Without knowing more detail (your age, salary etc) its hard to be specific. However I would make the following points:
- Obviously the earlier you start contributing, the better
- The higher the contribution ther better
- You will get a tax break on personal contributions, so for every €100 you contribute the net cost to you will be lower - depending on whether you are a 20% or 41% taxpayer
But:
- Whilst pension savings is long term (you wont get the funds back until you retire), you have to live today
- If you have a mortgae, spouse, kids etc it is probably unreasonable to expect to max the pension contribution.
- You have to balance the need for long term savings with short term expenditures
- You really need to work out what you can afford to save (net of tax relief), so if you can manage a net €100 p.m. then you are looking at investing circa €200 gross (before tax refief for top rate taxpayer)
If you die before reaching retirement, the value of the fund (employee + employer contributions) will generally be paid to your estate (subject to certain rules).
When you die in retirement, the value of the fund can also pass to your spouse (again subject to certain rules) and depending on how you invest the fund at retirement.
Hope this helps
