Enter your total monthly expenses — rent, food, utilities, subscriptions, and so on.
Choose how many months of coverage you want (3–6 is common; 6–12 for freelancers).
Add your current savings and monthly savings rate to see how long it takes to hit your target.

First fund: Starting from zero, a $500/month savings rate can build a 3-month cushion in under a year.
Freelancers: Variable income means 6–12 months of expenses is safer than the standard 3.
Dual income households: 3 months may be sufficient if both partners work stable jobs.
