Firecalc Question

[halo]

I have a question about using the Firecalc calculator.

If I'm receiving, say, 10K of income from a source wholly outside of my portfolio (not a pension) for the first, say, 10 years of my retirement and then this income stops entirely after the first 10 years, how do i enter this into the Firecalc calculator?

I should be able to increase my SWR spending somewhat from this, but I can't figure out how to use the calculator to find out how much of an increase it would amount to (it's not much, I know).

Thanks for your help with this.
