When you save for a goal, the biggest risk is a surprise expense cutting it short. The car breaks down, a health bill appears, a job changes. Without separate money on the side, you either dip into your goal savings or put it on a credit card. Both roll the snowball backwards.
An emergency fund is money set aside only for situations like these. Its job is not to earn a return but to be there right away when you need it.
How many months of expenses?
There is no single right number. The widely accepted range is 3–6 months of essential expenses. The US Consumer Financial Protection Bureau (CFPB) suggests, rather than a fixed figure, setting a goal by thinking about the unexpected expenses you have had before and what they cost.
Your situation decides which end you should be near:
| Less may be enough (3 months) | More may be needed (6 months or more) |
|---|---|
| Regular salary, secure job | Self-employed, irregular income |
| Two incomes in the household | One income in the household |
| No dependants | Children or other dependants |
| No rent or loan payments | Rent or loan instalments |
By essential expenses we mean costs you can’t cut: rent, bills, groceries, transport, insurance and loan instalments. Postponable spending such as holidays or eating out doesn’t count. If you don’t know your expenses, look at the average of the last 2–3 months.
With inflation, the fund must grow too
When inflation is high, the target of an emergency fund doesn’t stay fixed. If your expenses are ₺30,000 a month today and prices rise 30%, they will be ₺39,000 a year from now. A 6-month fund that needs ₺180,000 today will need ₺234,000 in a year.
Two things follow:
- Update the target at least once a year. As expenses rise, so does the target.
- Don’t keep it where it melts. Money in a current account or in cash loses purchasing power. An interest-bearing account, as long as it stays accessible, slows the melting.
Where should you keep it?
An emergency fund should be safe, accessible and separate.
- Safe: Instruments whose value can swing a lot in the short term don’t suit an emergency fund. If you need the money during a dip, you may have to sell at a loss.
- Accessible: You should be able to withdraw it within days, without penalty or at low cost. Breaking a time deposit early means losing interest, so splitting the fund across maturities can be an option.
- Separate: If the fund sits in your everyday account, it gets spent without you noticing. The CFPB also lists a separate bank account as one of the safest options.
How to start
Six months of expenses can feel daunting. Starting small is fine:
- Set a small first target: one month of expenses. Even that keeps a small surprise off your card.
- Automate: Set up a transfer of a fixed amount to a separate account on payday.
- Use one-off income: Put part of a bonus or tax refund into the fund.
- Refill it after use: Once used, the fund is refilled before other goals.
An example
Your essential expenses are ₺30,000 a month, you have ₺20,000 put aside and you can add ₺10,000 a month. Suppose the fund earns 35% a year after tax and your expenses rise 30% a year:
- 3-month target: ₺90,000 today. You get there in about 8 months; by then the target has risen to around ₺107,000.
- 6-month target: ₺180,000 today. You get there in about 20 months; by then the target is about ₺279,000.
Had you ignored the growing target, you would have reached ₺180,000 in 14 months and thought you were done; but by then that money would cover only 4 months of expenses.

How Kartopu calculates it
In Kartopu you can set up your emergency fund as a goal:
- Add your expenses as records and see the monthly total.
- Create an “Emergency fund” goal and set the amount as a multiple of your expenses.
- Set inflation and return in plans; see in three scenarios which month the fund is complete.
You can also tell Karto: “Set an emergency fund goal of 6 months of my expenses.” Karto asks for anything missing and shows a draft; nothing is saved until you approve.
