How Much Emergency Savings Do I Need?
An emergency fund target is usually stated as months of essential expenses: what you would still have to pay each month if your income stopped. Enter those costs below, either as one monthly figure or as a list where you decide what counts as essential, and the calculator works out a target, how far your current savings go, and what it takes from each paycheck to get there.
Emergency fund calculator
Enter your essential monthly costs and what you have saved. The target is months of those costs; add your pay schedule to see the contribution per paycheck and a date. Nothing is sent anywhere.
Plan it from your paychecks (optional)
With a pay schedule the calculator uses your real paydays, so a year with 27 biweekly paychecks has 27 contributions, not "two a month".

And 12 more planned contributions. The CSV and the printout list every one.
The target reflects only the expenses you entered, and your savings are as you typed them: nothing is checked against an account. Planned contributions are projections, not deposits. Keep emergency savings apart from the money you spend, so they are not counted as spending money.
The figures it starts with are an example. Replace them with yours. Nothing you enter leaves this page.
How the emergency fund calculator works it out
The target is months of the essential expenses you entered, and nothing else. Choose 1, 3 or 6 months, or a custom number from half a month to 24 months. The calculator multiplies your essential monthly expenses by that number and rounds to the cent. The result reflects only the costs you entered: it does not know about debts, dependants, health costs or anything you left out, and a fund that meets a generic target is not proof that it is enough for your household.
Only essentials count, and you decide which those are. In "List my expenses", every cost has an Essential box. Tick the ones you would still have to pay if your income stopped: rent or mortgage, utilities, groceries, insurance, transport, minimum required debt payments, childcare. Leave subscriptions and other things you would cancel unticked. Unticked costs are listed but not counted.
Every repeating cost is converted to a month the same way. Through a yearly count, then divided by 12:
- weekly costs × 52 ÷ 12 (about 4.33 a month, not 4, because a year has 52 weeks)
- every-2-weeks costs × 26 ÷ 12 (about 2.17 a month, not 2)
- twice-a-month costs × 24 ÷ 12
- every-3-months costs × 4 ÷ 12
- yearly costs ÷ 12
Each line is rounded to the cent once, and the lines are added, so the breakdown under the result always adds up to the monthly figure shown.
One-time costs are never turned into monthly ones. A $900 car repair is not $900 a month of living costs, so a one-time entry is listed as "not counted" rather than added to your monthly essentials.
Missing figures are never read as zero. With no expenses entered there is no target to show, and the calculator says so instead of telling you $0 is needed. If your essentials genuinely add up to $0, it explains why that is almost never the right number to plan from.
Savings are what you type. Your current emergency savings are your own figure: nothing is checked against an account, and they are treated as money held apart from your spending money, not as cash available for bills. Savings above the target show as fully funded, with $0 still needed and no contribution planned.
Building it from each paycheck
Add your pay schedule and the calculator uses your real paydays, the same dates as the paycheck calendar, instead of assuming two paychecks a month. A biweekly year with 27 paydays has 27 contributions.
- A planned amount per paycheck gives a savings timeline: each planned contribution, the projected balance after it, and the payday the target is reached. The last contribution is only what is still needed, so the projection never overshoots the target. Past ten years it says so instead of inventing a date.
- A target date gives the amount needed from each paycheck that arrives strictly before that date, using the same rule as the sinking fund calculator: a paycheck landing on the date itself is too late to count, and the amount is split in whole cents so the contributions add up to the target exactly.
- Your take-home pay adds an on-average check: your monthly essentials converted to one paycheck (monthly × 12 ÷ paychecks a year) are taken off your take-home, and the contribution is compared with what is left. When it does not fit, the result says by how much and what would fit instead. It never changes the amount you chose.
Every future contribution is labelled planned or projected. A plan is not a deposit, and nothing here moves or records money.
Averages hide heavy weeks. To check a contribution against the bills each specific paycheck has to cover, use the paycheck allocation calculator, which now plans an emergency fund and other savings goals paycheck by paycheck and shows any paycheck where the savings do not fit.
1, 3 or 6 months?
The calculator always shows all three side by side, because the choice depends on your situation rather than a rule:
- 1 month is a starter fund: enough to stop a single surprise bill turning into debt, and a realistic first milestone.
- 3 months is a common planning target for a steady salary in one household with more than one source of support.
- 6 months or more is often chosen for a single income, irregular or commission pay, dependants, or a job that takes a long time to replace.
These are planning choices, not universal financial recommendations. Pick the one that matches what you would actually need to get through, and remember the figure only covers the costs you entered.
A worked example
Rent $1,250 a month, groceries $110 a week, utilities $160 a month, car insurance $720 a year and a phone at $65 a month. Groceries become $476.67 a month (110 × 52 ÷ 12) and car insurance $60.00, so essential expenses come to $2,011.67 a month. A streaming subscription is left unticked and not counted.
With $1,500 already saved:
- 1 month: target $2,011.67, still needed $511.67 (74% there).
- 3 months: target $6,035.01, still needed $4,535.01 (24% there).
- 6 months: target $12,070.02, still needed $10,570.02 (12% there).
The $1,500 covers 0.7 months of essentials today. Saving $150 from each biweekly paycheck reaches the 3-month target after 31 paychecks, about 14 months. To get there in a year instead, the 26 paychecks before that date need $174.43 each (the last one $174.42). On an $1,800 take-home paycheck, essentials average $928.46 per paycheck, leaving $871.54, so either amount fits on average, before everyday spending.
Building it one paycheck at a time, after the bills
The take-home check above is an average: essentials spread evenly over every paycheck. Real paychecks are uneven. The one before rent carries far more than the one after it, and a contribution that fits on average can leave one pay period with almost nothing to live on. Here is how to set a contribution that works on every check, not just on paper.
The example. Take-home is $1,850 every other Friday, with paydays on February 5 and February 19, 2027. Monthly bills come to $2,080 (rent $1,400 on the 1st, car insurance $130 on the 5th, a $310 car payment on the 12th, $35 of streaming on the 16th, utilities $140 on the 20th, phone $65 on the 24th), and groceries run $110 a week. Essential expenses are $2,080 + $476.67 of groceries (110 × 52 ÷ 12) = $2,556.67 a month. A one-month starter fund is $2,556.67; three months is $7,670.01.
1. Cover each paycheck's bills first. Giving each bill to the last paycheck before its due date, the February 5 check carries $475 and keeps $1,375. The February 19 check carries $1,605, including March 1 rent, and keeps $245. The paycheck allocation calculator does this for your own dates.
2. Test the contribution against the lighter check, not the average. $150 from each check leaves the first with $1,225 for its 14 days ($87.50 a day) and the second with $95 ($6.79 a day). That second contribution is the one that ends up skipped, or quietly paid back with a credit card.
3. Even out the bills, then save the same amount from every check. Set aside $565 of rent from the February 5 check and both checks commit $1,040 to bills and keep $810. Now $150 from each leaves $660, $47.14 a day, on every check. The biweekly budgeting guide walks through that step in full.
4. Aim for the starter fund first. At $150 a paycheck from February 5, the one-month fund is reached on the 18th contribution, October 1, 2027, with the last contribution only $6.67. Three months takes 52 paychecks, about two years. Enter your own figures above and the calculator lays out the same timeline for your paydays.
5. Move the money on payday. A transfer made the day the paycheck lands is a bill the budget plans around. One made at "the end of the month" competes with everything else, and on a biweekly schedule there is no end of the month, only the end of each pay period.
6. Add genuinely spare money, but only after its bills. A tax refund, a bonus or part of a third paycheck can speed the fund up. A third paycheck often carries the next month's rent, so check what is due before the following payday first; the three-paycheck month guide works through an example.
Common mistakes:
- Saving a fixed percentage of gross pay without checking what each paycheck actually has left after its bills.
- Taking the same amount from the check that carries rent before evening the bills out.
- Counting the fund as spending money. It stops working the moment it is part of the balance you spend from.
- Treating planned contributions as savings. A contribution exists once it has moved, not when it is scheduled.
- Stopping after the first emergency. Using the fund is what it is for; rebuilding it is the next goal, at the same per-paycheck amount.
What this assumes. Pay arrives on schedule and in the same amount. If your income varies, start smaller and test it with the irregular income stress test, which shows your lowest balance if the next payment is smaller or late. If your paycheck has just changed, see how to budget when your paycheck changes.
Where the money lives
An emergency fund only works if it is not quietly spent. Keeping it in a separate savings account, not in the checking account you spend from, is what stops it being counted as spending money. For the same reason this calculator never adds your emergency savings to your available cash, and the paycheck planner never uses them to pay a bill.
Emergency fund or sinking fund?
An emergency fund is for things you cannot predict: a job loss, a burst pipe, an urgent repair. It is one pool with no due date. A sinking fund is for an expense you know is coming, such as an insurance renewal or holiday gifts, with an amount and a date. The sinking fund calculator handles those. Keeping the two apart is what stops a known expense eating the money meant for a genuine emergency.
The free calculator and the app
This calculator gives you a target, a per-paycheck figure and a timeline, and you can print the plan or download it as a CSV file. Both are made in your browser. It answers the question once and keeps nothing.
Pocket Runway keeps the plan going: your pay schedule and recurring bills, a savings goal that reserves its share from every pay period before showing what is left to spend per day, and the figures recalculated as you track spending. Nothing typed into this calculator is carried into an account; you would enter your goal in the app yourself.

Emergency fund questions
How much emergency savings do I need?
A common way to size it is months of essential expenses: what you would still have to pay if your income stopped. Three months is a frequent planning target and six months is often chosen for a single or irregular income. Enter your own essential costs above to see each target in dollars, and remember the result only reflects the costs you entered.
What counts as an essential expense?
Costs you would still have to pay with no income: housing, utilities, groceries, insurance, transport to work or medical care, minimum required debt payments and childcare. Subscriptions, eating out and anything you would cancel are usually not essential. The calculator never assumes: you tick each one.
How much should I save from each paycheck for an emergency fund?
It depends on your target and how soon you want it. With a target date, the calculator divides what is still needed across the paychecks that arrive before that date, using your real paydays. With a planned amount, it shows when you would reach the target. Add your take-home pay to see whether the amount fits after your essentials, on average, and use the paycheck allocation calculator to check it against each paycheck's real bills.
How do you convert weekly or biweekly costs to a monthly amount?
Multiply by the number of times the cost happens in a year, then divide by 12: weekly × 52 ÷ 12, every 2 weeks × 26 ÷ 12. Multiplying a weekly cost by 4 understates it by about a month's worth every year.
Is a three-month emergency fund enough?
It is enough to cover three months of the expenses you entered, which is a reasonable target for many people with steady pay. It may not be enough for a single income, irregular pay, dependants, or a job that takes longer to replace, which is why the calculator shows 1, 3 and 6 months side by side. Meeting a generic target does not mean the fund covers every situation.
Should my emergency fund be in my checking account?
It is usually kept somewhere separate from the account you spend from, so that it is not counted as spending money by accident. Wherever it is, this calculator treats it as held separately and never adds it to the cash available for bills.
Can I print or download my emergency fund plan?
Yes. "Print or save as PDF" prints the targets, the 1, 3 and 6 month comparison and the full savings timeline, and "Download CSV" saves the same figures for a spreadsheet. Both are generated in your browser from what is on screen.
This calculator is general educational information, not financial advice. It works only from the figures you enter and does not know about interest, taxes, debts or anything else outside them. All example figures are illustrative. It runs entirely in your browser: nothing you type is sent anywhere, stored, or added to a Pocket Runway account, and the printout and CSV are generated on your device.
