Title: Accounting for removal of expenses for children in retirement calcs
Post by: Gin1984 on April 19, 2014, 12:36:48 PM
Prior to my daughter being born, I was unemployed, in a Master's program and we were living on my husband's $26,000 grad salary, our tenant's gave us money for retirement savings (about $4000/year) and our roommate gave us some wiggle room (about $200/month).  Then our daughter was born, and I got into the PhD program.  My salary is $25,000 but much of it is taken up by our daughter's expenses (daycare is $244/week), taxes and retirement savings ($625/month plus 3% of my salary to a pension).  We now use the income from the tenants for side savings/debt pay down because my husband is graduating and our EF was mostly money from subsidized student loans so I want to pay all of his student loans down, save an EF and save for moving in 3 years.  So, that is my reasoning for staying at 15% retirement saving for now.  But then I was thinking, we only really need $30K in retirement (not including inflation) because we don't plan to retire till we pay our kids way (we plan to have a second kid) through college, not the whole 51-55K.
I wondered how other MMM parents considered children's expenses.  They are not savings, but they are not spending account for in retirement.

MMM's Shockingly Simple Math (http://www.mrmoneymustache.com/2012/01/13/the-shockingly-simple-math-behind-early-retirement/) being a simplification (surprise there!), it doesn't account for things like lower expenses after retirement. However, FIRE calculators like FIRECalc (http://firecalc.com/) and cFIREsim (http://www.cfiresim.com/input.php) have inputs for "other spending" which let you enter other costs that are one-time, or recurring within a particular timespan.
