The standard advice says three to six months. Here is what that actually looks like for a mechanically capable family that plans for their own version of things.
Everyone knows the rule: three to six months of expenses in an accessible account. That advice is written for the average family, and most families need it.
We are not the average family.
The Co-Pilot is home with the kids. No daycare costs. And I handle a lot of our own repairs, which means the things that blindside most families cost us significantly less or do not blindside us at all.
Here is what we actually keep, how we think about it, and why the standard advice was not written for us.
The repairs we do ourselves

Most emergency fund advice assumes your car breaks and you pay a shop. Your water heater goes and you call a plumber. Your alternator dies and you are writing a check.
That is not how it works around here.
I learned most of this through YouTube, trial and error, and family and friends who know their way around a garage. When something breaks, I figure it out.
A few of the things I have actually done:
- Replaced the starter on my 2007 Tundra
- Replaced the half shaft on the Chrysler 300
- Reran the brake lines on the Chevy Silverado
None of these were fun. All of them worked. And every one of them would have been a $300 to $800 bill plus the wait time and the feeling like you are at the mercy of someone else’s schedule.
Our home repairs: everything except the AC unit and the roof. Plumbing, drywall, the things that would send most people searching for a number to call.
This changes the emergency fund math. Not to zero, things still break in ways I cannot fix, but the cost profile is nothing like what the standard advice assumes.
The number we actually keep: $10,000
The standard advice says three to six months of expenses. For a family of four with a mortgage, that number can get eye-watering fast.
We keep $10,000 in a high-yield savings account.
$10,000 is not a lot of runway. I know that. But it is not meant to be our entire financial story. It is a bridge. It covers the deductible if something big happens, the slow month, the gap between one income dip and the next.
The rest of our savings is in the market, working. That is the point. We are not letting money sit in a savings account when it could be compounding for us over the next twenty years.
What about a life-threatening medical situation?
This is usually where the $10,000 conversation gets uncomfortable.
Here is our answer: if it is life-threatening, we use the HSA. That is what it is there for. Protecting our family comes before any account balance.
If we deplete the HSA, we rebuild it in a Roth IRA within a year. We have done this before and we will do it again if we have to.
That is not the optimistic version of the plan. That is the real one.
What about a major breakdown that costs more than $10,000?
Here is the honest answer: we recently consumed our HSA and took a $35,000 loan from our 401k to eliminate high-interest debt and get back to normal after the medical costs and family expenses piled up.
We are recovering. We are on the other side of the hard part.
Our plan: sell the house within a year, pull the equity, put $50,000 to $60,000 back into the 401k loan and a Roth IRA to reset our balance to where it was.
That is not in the emergency fund. That is in the bigger plan. Selling the house is the move that puts us back on track, not a giant savings account that sits there earning 4% while we could be investing it.
The philosophy underneath it all
Life is about choices. You plan for yours and you adapt accordingly.
We are not planning for every worst-case scenario. We are planning for the ones that actually happen to a family like ours, and we are building a financial life that can absorb the hits and keep moving.
That means $10,000 in the HYSA as a bridge. It means the HSA as our medical backstop. It means a plan to sell the house and reset the balance within a year.
It does not mean $30,000 sitting in a savings account earning 4% when we could be putting it to work in the market for the next twenty years.
The standard advice is fine if you are the average family. We are not average, and your family probably is not either.
Know your actual situation. Build your actual plan.

Frequently Asked Questions
How much emergency fund does a family with kids actually need?
There is no universal answer. The standard advice is three to six months of expenses, but that number assumes you are paying full price for everything that breaks. We keep $10,000 as a bridge because we handle a lot of our own repairs. Your number depends on your actual cost profile, not the average family is one.
Is $10,000 enough for an emergency fund?
For us, yes. It is not meant to cover every possible scenario — it is meant to bridge the gap. For the big stuff, we use the HSA. For the income dips, $10,000 covers it. The rest of our money is in the market, working. That is intentional.
What if we have a medical emergency and wipe out the HSA?
We rebuild it. We have done it before. If we deplete the HSA, we move money into a Roth IRA within a year to recover the ground. Life is about choices — we plan for ours and we adapt accordingly.
Where should you keep an emergency fund?
High-yield savings account. 4% right now, accessible in a few days, no market risk. Not the stock market, not a CD with a penalty. Just a boring account earning a reasonable rate and sitting there when you need it.
