What is an emergency fund for?
An emergency fund is cash set aside for costs you cannot predict and cannot avoid: losing your job or hours, a medical bill, an urgent car or home repair, a last-minute trip for a family emergency. Its job is to stop a bad week from becoming debt.
It is not for costs you can see coming, even if they are large and irregular: car insurance renewals, holiday gifts, annual subscriptions, a new phone. Those belong in sinking funds, saved for separately. Keeping the two apart is what stops the emergency fund from slowly emptying on things that were never emergencies.
How do I work out my essential monthly costs?
Essentials are what you would still have to pay if your income stopped tomorrow and you cut everything you could. Use your real bills, not your full budget. An example, with illustrative numbers:
| Essential | Per month |
|---|---|
| Rent or mortgage | $1,400 |
| Utilities | $160 |
| Groceries (basic, not the usual) | $450 |
| Transport | $250 |
| Insurance | $130 |
| Phone | $50 |
| Minimum debt payments | $120 |
| Medicine and prescriptions | $40 |
| Essential monthly costs | $2,600 |
Left out on purpose: eating out, most subscriptions, clothes, travel, and the money you normally put into savings. In a real emergency those stop first, so the fund does not need to cover them.
How many months of expenses do I need?
emergency fund target = essential monthly costs x months of cover
| Months of cover | Target at $2,600 a month | Usually enough when |
|---|---|---|
| 3 months | $7,800 | Steady salaried job, two incomes in the home, few dependants |
| 6 months | $15,600 | One income, children, or a job that would take a while to replace |
| 9 to 12 months | $23,400 to $31,200 | Self-employed, freelance, commission or seasonal income |
Move up a row if any of these apply: you own a home (repairs are yours), you have a high insurance deductible or excess, your industry is cutting jobs, or you support someone else. Move down a row only if you have another reliable cushion, such as a partner whose income alone covers the essentials.
What is a good first goal if six months feels impossible?
Build it in stages, because each one is useful on its own:
- A starter fund: enough for the most common surprise, such as a car repair or a dental bill. Many people use $1,000, or £1,000, as a first target.
- One month of essentials: $2,600 in the example. This covers a late paycheck or a short gap between jobs.
- Three months: $7,800. The usual minimum full fund.
- Your full target: six months or more if your situation needs it.
Even a small fund changes what a surprise costs. A $400 repair paid from savings costs $400. The same repair put on a credit card and paid back slowly costs $400 plus months of interest; the minimum payment guide shows how much.
How long will it take to build?
months to reach the goal = (target - already saved) / amount saved per month
Three months of the example essentials is $7,800. Starting from $600 already saved:
- At $300 a month:
(7,800 - 600) / 300 = 24months - At $450 a month:
(7,800 - 600) / 450 = 16months - At $600 a month:
(7,800 - 600) / 600 = 12months
Ways to get there faster without a stricter budget:
- Set up an automatic transfer on payday, so the saving happens before the spending.
- Send windfalls straight to the fund: a tax refund, a bonus, money from selling something.
- If you are paid every two weeks, save the two extra paychecks a year. The paycheck calendar shows which months they land in.
- Cancel one subscription and redirect its amount; the subscriptions guide helps you find them.
Where should I keep my emergency fund?
Somewhere that is separate, so you do not spend it by accident, easy to reach within a day or two, and safe, so the amount does not fall right when you need it. That usually means a savings account at a bank or credit union covered by deposit insurance: FDIC or NCUA in the US, FSCS in the UK, CDIC in Canada, each up to its limit.
A high-interest or easy-access savings account is the usual choice. In Canada, some people hold it as cash savings inside a TFSA so the interest is tax-free; in the UK, a cash ISA can do the same, as long as it allows withdrawals without a penalty.
Not a good home for it: investments that can fall in value, an account with a notice period you cannot get around, or a credit card limit. Available credit is a loan you would have to repay, not savings.
When should I use it, and how do I refill it?
Use it when the cost is necessary, urgent and unexpected. Ask all three: do I need this, does it have to happen now, and could I have seen it coming? A broken boiler in winter passes. A sale on a new TV does not.
After you use it, refill it before going back to other goals. Work out the gap and treat it like a bill: a $900 withdrawal refilled over six months is 900 / 6 = $150 a month.
Can Tally help me build an emergency fund?
Tally's bill calendar and subscription list show your recurring costs in one place, which is most of the essentials list above. Both are free.
If you want a budget built around saving, the Aggressive Saver template on the Budgets tab is made for building an emergency fund: it sends 47% of the monthly income you enter to savings, and you can change any line. If you would rather track the fund with a target and a date, an envelope with a sinking-fund target shows how much to put in each month to get there; envelope targets are part of Tally Pro. Tally never moves real money; the fund itself stays in your savings account.
