Keys to Determine the Ideal Size of Your Emergency Fund
Keys to Determine the Ideal Size of Your Emergency Fund
A CNBC report states that households with an emergency savings fund are 29% more likely to cover unplanned
expenses without debt.
This blog post is intended to help you better understand emergency funds and provide direction on determining your emergency fund size.
First, let me acknowledge how hard it can be to build an emergency fund.
After paying rent and mortgages, we barely have money left for groceries, cell phones, and day-to-day expenses.
Nevertheless, emergency funds are necessary because sometimes life just won’t let us be great.
Imagine discovering that your emergency fund doesn’t need to be the conventional 3-6 months rule everyone talks about OR that it needs to be much more.

What’s the purpose of building an Emergency Fund?
Emergency funds are intended to cover unexpected, major, and income loss expenses. As much as we’d like these things not to happen, they will inevitably occur.
They serve as a shield against the damage caused by unexpected expenses.
If you don’t have enough money to easily access when you need to pay for something urgent or unexpected, your options are limited.

Emergency Fund Examples
Investment Account – If you have an investment account, you can sell stocks but may incur taxes or lose out on future growth.
Friends and Family—You can borrow money from family or friends, but that well usually runs dry quickly.
Credit Cards – You can charge a credit card if you have available credit and hope to pay it off before it charges you 20%+ interest.
HSA — Ideally, an HSA should be used for large medical expenses. These could obviously be unexpected, but the real hero use of an HSA is during retirement years because this account can grow preretirement.
Sure, there is a list of alternatives (more than above) to a traditional emergency fund, but few make more sense and present the same type of liquidity and benefit.
Why Should You Build an Emergency Fund?
About 8 years ago, my family and I were at home watching TV in the middle of a Chicagoland winter. It started to feel colder and colder as the evening progressed. The heat was on, but we decided to turn it up because we were used to our home being really drafty.
It felt warmer, and when we checked it, we realized the furnace was broken. We knew we couldn’t make it through one night without heat, but definitely not multiple nights, so we called a company for emergency service repair.
The repair guy inspected the furnace and told us it was unrepairable and that a new one would cost about $3000.
Freezing temperatures, Chicago winner… no option but to replace the furnace.
Within the next 24 hours, we had a new furnace and a new credit card balance that was $3,000 higher.
Fortunately, we had the money easily accessible in a high-yield savings account. Still, if that had happened to us 10 years prior, we wouldn’t have had the liquid cash.
Even though we put the charge on a card, we didn’t want to have to pay off $3,000 at a 27% interest rate.
When the bill came due 30 days later, we transferred money from the savings account to our checking account to pay off the balance.
So, even though we used a credit card to make the purchase and accumulate some points, thankfully, we had enough money in the bank to cover the debt.

Who Should Have an Emergency Fund
Short answer – people with bills
Long answer –
Single people should have an emergency fund because they are typically the sole breadwinner.
Married people should have an emergency fund because you’re more likely to have unexpected crap when two people are involved versus one.
For individuals with children, see above about married people.
Suppose you have debt or regular recurring expenses and rely on recurring or nonrecurring income to cover those expenses. In that case, you’re likely a good fit for an emergency fund.
Like my “why” story above, if you charge the expense to a credit card and don’t have enough discretionary income, you will likely not be able to pay off that credit card.
Where to Park Emergency Fund Account?
Probably not a good idea to keep your emergency fund in your house.
It should be accessible but secure; most people’s mattresses and freezers are unsafe.
Keeping a little petty cash in the house may not be a terrible idea, but this is usually a couple of hundred dollars, IF that makes sense for you and your lifestyle.
As the chart below shows, high-yield savings and money markets are typically the best options for housing your emergency fund.

What Emergency Fund size is right for you?
Establishing an emergency fund should not stress you out.
What’s the first step to figuring out how much you need?
Start where you are.
That may mean your $1,000 feels much more doable than 3 months of expenses.
You can build up gradually by transferring a piece of every paycheck into your paycheck.
Depending on your budget, a paycheck could be $5, $50, or $500.
Even better if you set it up to transfer automatically and build up to 10-15% of your income.
That said, it is rarely black and white.
So yes, three to six months could be a very reasonable and feasible number for you and your partner. But how do you know if it’s the right amount?
The size of your emergency fund will be determined by several things:
- fixed expenses versus discretionary expenses,
- level of discretionary income,
- income sources
- Income/Job security
- Health Concerns
- Household Size/Dependents
If your expenses are high because of your discretionary expenses versus your fixed expenses (rent, utilities, etc), then it gives you more wiggle room.
While you may not want to sacrifice all that brings you joy and peace, the size of your emergency fund should be based on your essential expenses.
Those with significant discretionary income and low expenses fall on the lower end of the “need” spectrum, but having one can’t hurt.
For example, your bills total $2,500 monthly, and you always have at least $10,000 left over.
Three months of expenses saved would total $7,500, but your discretionary spending exceeds that, so the probability of being significantly impacted by an unexpected expense is low.

Here are a few questions to help you determine how much you should save in your emergency fund. These questions apply whether you are single or partnered.
How many sources of income do you have?
The income isn’t just about the numbers on your paycheck. It’s about stability, predictability, and potential growth. So, evaluate all income sources to help you understand how volatile income may be.
The more volatile your income is, the more you want to save.
When was the last time you were unemployed, and for how long? And how long did the unemployment period last? Did you tap into existing emergency funds, and have you replenished them?
How easy is it for others to get a job in their field? If the economy is bad, finding a new job may take longer than normal.
If it took you 6 to 9 months to secure a stable income after your last layoff, then a 3-month emergency fund is probably not enough.
When was your last promotion, and do you expect a promotion soon? If you or your partner have been in the same role for several years, there are a few things to consider:
-
- Have you maintained certifications or continuing education credits to keep your skills up-to-date?
- Where are you on the pay scale for your company or industry?
- How marketable are your skills outside of the current employer? Are they easily transferable into another role?
- If below-average performance is an issue in their current role, then job security may be threatened. Maybe there is a possibility of being downsized or laid off.
How much access to credit or other income sources do they have?

Safeguard Your Savings with Lifestyle in Mind
The state of your health also plays a role.
Physical and mental health can be the unvoiced factor silently impacting your savings plan.
Imagine an unexpected medical bill or a period of illness causing your financial security to waver. Keep things like hospital stays, emergency surgeries, or things requiring you to experience longer downtimes.
If you have adequate disability or critical insurance, your emergency fund may not need to be as large.
Lastly, the number of people in your household can impact you if those individuals depend on you. If you’re in the sandwich generation, your parents and children rely on you somehow for survival.
Their additional needs and expenses need to be considered. If your child is in sports, injury or surprise expenses are likely. You might need to subsidize expenses for aging parents.
After all, dependents aren’t just costs – their needs deserve financial protection.
Can you have too much money in your Emergency Fund?
Emergency fund size is important, but it is absolutely possible to save too much in the account.
There’s a term called cashdrag.
This means that holding too much money in cash can negatively impact your financial health compared to investing it in other areas to help it grow.
It’s essentially the opportunity cost of not investing “in something” that could yield higher returns.
Once you determine the size of your emergency fund, redirecting excess funds to retirement accounts, investment accounts, or other investment opportunities may be the next best thing.
This depends heavily on your risk tolerance, market conditions, and investment philosophy.
Regularly review your expenses and lifestyle to ensure your emergency fund remains sufficiently aligned.
