I recently discussed how your savings rate can determine when you’ll be able to retire.  To go along with the table in that post, I developed the Saving Retirement Calculator below.  You can enter specifics for your situation to see when you might be able to retire.  Once you have an answer, you can copy the badge code and paste it into your webpage or blog to get a badge that looks like this:

Note that changing income will have no effect on the answer, unless you currently have a non-zero amount saved.  That is due to the fact that calculations are all made on a relative basis, i.e. if you are saving 10% (and thus living on 90%) 90% x 25 is the amount you’ll need to save, which does not need absolute current income to be  calculated.

Here’s the calculator:

Entry parameters include your current after tax income, assumed inflation, annual raises, and investment returns, value of your account now, and the percentage of your income that you are planning to save.
