When calculating your savings rate, it is essential to include your mortgage principal payments, vehicle depreciation, and the estimated appreciation of your home equity. Most calculators fail to account for these crucial variables.

Bookmarked this. Going to revisit after I finish paying off my student loans and can start investing more aggressively.
