Three or six? Be honest
Lean three months
Two stable incomes, in-demand skills, low fixed costs, good insurance.
Lean six months
One income, commission or gig pay, specialized field, kids or dependents, health issues, or a mortgage.
It's a range, not a grade
3.8 months saved is not failure — every week of runway is real safety.
Keeping a big cushion smart
Split for yield, keep one month liquid
One month instantly reachable in savings; the rest can ladder into CDs or T-bills for better rates with staggered maturity dates.
Don't invest it
Layoffs and market dips travel together. This money's only job is existing when needed.
Review size yearly
Rent went up? New baby? The 'month' that defines the fund changed too — recount it.
Then STOP growing it
Past six months of essentials, new savings does more elsewhere: goals, retirement, investing. Hoarding cash has a real cost too.
