If you go take 4 extra years out of your portfolio to make up for the shortfall before you start collecting SS, you are no longer following the plan that you entered into Firecalc.
If you use a tool like I-orp, it would have you taking more out of your portfolio early, then reducing that when your SS kicks in.
Someone more familiar with those tools can correct me if I'm wrong.
Like you say, it's only 4 years. But if you were doing this for 20 years, I think you could see clearly this is wrong and puts your portfolio at risk. For 4 years, or even 1 year, is still wrong, but just not nearly as risky as 20 years.
In the "investigate" page of firecalc, there is a "Given a success rate, determine spending level for a set portfolio" this takes into account the data you enter regarding your SS benefits
When I run in this mode and don't include SS the difference in what it says my speeding level is is about 14000 a year less which is less than my as benefits at FRA so it is accounting for SS input in a manner that one would expect
