For comparison, this is a calculator that was built by actuaries[1] for the Australian market:

Some really important things that are built into it are:

- Everything is given in "today's dollars" and that's done by reference to a salary index, NOT a price index, to reflect increases in community living standards.

- It shows some indication of the income level you can expect during retirement given your lump-sum retirement benefit.
