Emergency Fund Calculator: How Much You Need

An emergency fund is measured in months of essential spending, not a round dollar figure. Enter what it truly costs to keep your life running — housing, food, utilities, insurance, minimum debt payments, transport — and choose the cover you want.
How Many Months Is Right
Three months suits a stable salary with a second income in the house. Six months fits most people. Nine to twelve months makes sense for freelancers, commission earners, single-income households, and anyone in a field where job searches run long.
Where to Keep It
A separate high-yield savings account: reachable in a day or two, but not attached to your debit card. Keeping it separate is what stops it becoming grocery money.
Filling It Faster
Side income is ideal for this because it never enters your normal budget. Automate a transfer on the day hustle payouts land, and treat the account as untouchable until an actual emergency.
Where the savings come from
The 50/30/20 split shows how much of each month's take-home pay can go to savings.
Once the starter fund is in place
The usual next step is high-interest debt. List every balance and see whether the snowball or the avalanche gets you out sooner.
Where to keep it

An HSA for medical costs
An HSA can hold savings for medical bills with a tax deduction; see your 2026 limit and what it saves.
Where to keep part of it
Money you won't need for a year or more can sit in a CD; see what it earns and what breaking it early would cost.
