Welcome to the board, Ric.
Your FIRECalc assets would be the things that you're going to sell off for spending cash during your retirement. You can add up all the assets into your retirement portfolio if you're planning to sell them all off eventually.
Another way to run FIRECalc would be to assume that your annuity will pay for a certain portion of your spending and your retirement portfolio will handle the rest. So, for example, if you're spending $30K/year and your annuity is $10K/year, your annual FIRECalc spending will be $20K. The drawback with this approach is that FIRECalc will raise your spending with inflation, but in real life your annuity will stay at $10K/year every year. In 20 years that'll barely pay your annual Starbucks latté bills.
A third (much more complicated) lump-sum cash value of your pension. This is fraught with assumptions and the numbers could vary wildly.
I'd take your annual spending, subtract your pension & annuities from that number, and assume that your portfolio has to support the remaining spending. Put that "remaining spending" number and your portfolio value into FIRECalc.
If you can figure out how much that $220K annuity will cough up each year then subtract that and your pension from your annual expenses and enter the remaining expenses into FIRECalc. Your portfolio would be the $32K plus the $500K (or however much you're willing to consider turning your real estate into cash someday).
Then go to "Advanced FIRECalc" and run the numbers all over again with your Social Security numbers...
If you have other FIRECalc questions you can post them on the "FIRECalc Support" board.
