We got a pretty nice modeler from our Retirement Club that has linked worksheets: budget, Retirement Needs, Wants and Wishes, Retirement income, etc. I was able to modify the spreadsheet to include several sources of retirement income, forecasting the changes with COLA, gains, taxes, etc. I also added our nest egg totals, withdrawals, draw downs required to meet our retirement budget on any given scenario in taking the retirement sources. I linked a few other spreadsheets: key on social security, pensions at various ages for both of us and one that just contains results (nest egg changes, funding totals) at key ages in our retirement journey. Its eye opening the difference between what you focus on and whats important like wheres the break even point between Early, Full and Late SS. Hoever that doesn't meet our retirement mission statement. We arent focused on dying with millions but more on have a little fun during our Go Go yrs. At some point we all end up on the park bench..
