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.

Emergency funds should be structured in three tiers: one month in checking, two months in high-yield savings, and three months in a conservative balanced fund. This structure optimizes liquidity while generating modest returns.
