Emergency Fund Calculator
How many months of expenses your emergency fund covers, and what to target next.
An emergency fund is what stops a job loss, a broken car or a surprise bill from turning into debt. The usual yardstick is three to six months of essential expenses.
This calculator compares the fund you have with your monthly essentials, shows the three-month and six-month targets and how much more each one needs.

A $6,000 fund against $2,500 of monthly essentials
A fund worth a bit over two months of essential spending.
You enter
- Essential monthly expenses
- $2,500.00
- Current emergency fund
- $6,000.00
You get
- Months of expenses covered
- 2.40 months
- Six-month target
- $15,000.00
- Still needed for six months
- $9,000.00
- Monthly saving to get there in a year
- $750.00
The fund covers 2.4 months. The six-month target is $15,000, so $9,000 is still missing, and putting that aside over twelve months means saving $750 a month. The three-month target of $7,500 is only $1,500 away.
A $1,000 fund against $1,800 of monthly essentials
A thin buffer with a lower essential spend.
You enter
- Essential monthly expenses
- $1,800.00
- Current emergency fund
- $1,000.00
You get
- Months of expenses covered
- 0.56 months
- Six-month target
- $10,800.00
- Still needed for six months
- $9,800.00
- Monthly saving to get there in a year
- $816.67
The fund covers 0.6 months. Three months needs $5,400 and six months needs $10,800, so the gap to six months is $9,800, or $817 a month for a year. Reaching the three-month target first needs $4,400, which is about $367 a month over the same year.

Frequently asked questions
Which expenses belong in the monthly figure?
Only the costs that continue if your income stops: housing, utilities, food, transport, insurance, childcare and minimum debt payments. Leave out holidays, gifts, restaurant meals and subscriptions you would cancel in a tight month, because the fund exists to cover the floor of your spending, not your current lifestyle.
It can help to build the number from a real month of spending rather than from memory. If the total feels uncomfortably small, it probably is: an emergency fund sized on an optimistic figure is the one that runs out first.
Is three months or six months the right target?
Three months is a reasonable floor when you have a stable salaried job, a second income in the household and skills that are in demand. Six months or more fits freelance and commission work, a single income, a specialised job market, or a health situation that could interrupt your earnings.
The calculator shows both targets and the gap to each, so you can decide which one you are actually aiming at. A useful approach is to reach three months first, then keep adding until you reach six, rather than treating the larger figure as the only valid milestone.
What should I do while the fund is still empty?
Start with a small, fixed amount that leaves your monthly budget intact, and automate it on payday so it does not depend on what is left at the end of the month. Even $50 a month builds the habit and covers the smaller emergencies, which are the ones that most often turn into credit card balances.
If you are also carrying high-interest debt, split the effort: keep a small starter buffer, then send the rest at the debt. Checking the timeline in the Debt Payoff Calculator shows what that costs in interest, which makes the trade-off concrete.
How do I save for an emergency fund and other goals at the same time?
Fund the emergency reserve first, up to at least three months of essentials, and only then direct money at planned goals. The reserve is what stops a car repair or a medical bill from being paid on a card, and without it every other goal gets interrupted by the same problem.
The monthly figure this calculator returns for a one-year build is a good temporary line in your budget. Once the target is met, that same amount can be redirected to a specific goal in the Savings Goal Calculator.
