Compare fixed pension to one with COLA (cost of living adjustment)
Note that this simplified calculator does not take into account the fact
that the money you receive earlier has a higher "value" than the same dollar
amount received years later. But if you spend all you receive, that does not
make much difference anyway! The COLA amounts turn green once they surpass
their fixed pension couterparts. This should help you gauge how long you need
to live for the COLA payments to be worth it over a fixed pension.
