Two ways among many:TheTimeLord wrote: ↑Wed Mar 29, 2023 8:01 am I was wondering how other people adjust their retirement expenses estimates over time. Late last year I started adjusting mine using the CPI REF # that is used for TIPS. What methods are other people using to keep their estimates fresh going forward?
1. Current year = actual. Forecast (future) years indexed by CPI. This is a broad brush forecast.
2. Build a budget (income statement) and forecast each line item. Some line items may not increase, or at a rate less than CPI. Some line items might increase more than CPI. This is a more granular way to forecast.
