A few months ago, I got into a dumb and completely avoidable bike accident. Â My wife and I were biking to meet up with a friend that lives not too far from us. Â The bike path that leads to our friend’s apartment winds its way through campus and part of the path goes through this narrow strip that’s basically an alley behind a building. Â Traffic on this path goes in both directions.
You can probably see where this is going. Â As I was traveling along this path, I ended up looking down at my phone and found myself veering into the other lane. Â Another biker came around the corner and I rode into him headfirst, toppling both of us off our bikes. Â The incident was definitely a learning experience to not mess around with your phone when you’re on a moving bike.
Thankfully, neither of us was injured. Â Unfortunately, the crash did cause damage to the guy’s front wheel. My bike remained unharmed – and even if it was damaged, it wouldn’t have mattered because I was on a bike share bike. They handle the bike maintenance, not me – another reason why bike share systems are awesome.
It’s taken me a while to write about this incident because, frankly, it’s embarrassing. Â But as I look back on it, I realize there’s something that I can share here. Â After making sure we were all okay, I told the guy to go get his bike fixed and send me the bill. Â He didn’t expect it would be super expensive – only part of the bike was messed up. Â Still, it was a costly mistake. Â The repairs ending up costing around $190. Â He had a pretty fancy bike that required a special part.
Luckily for me, I’ve had money that I’ve been setting aside for the past couple of years to handle situations exactly like this. Â It’s my stupid mistakes fund. Â As a result, even though I wasn’t expecting it, I already had $190 set aside to cover this mistake.
My Stupid Mistakes Fund
I first learned about the stupid mistakes fund from Ramit Sethi, way, way back in the day (I think I must’ve been in college or just out of college when I first learned about it). Â A link to his post explaining the stupid mistakes fund can be found here.
Basically, the idea with the stupid mistakes fund is to save a small amount of money each month to cover “unexpected” – but really, when you think about it – expected mistakes. Â None of us is perfect, so we’re all going to make stupid mistakes in our life. It’s just a matter of when.
I use my stupid mistakes fund to cover these dumb things that I do. Think about all the times you’ve lost or broken something, or got a dumb ticket, or paid some stupid fee. These are all things that are perfect to cover with your stupid mistakes fund.
Since starting my stupid mistakes fund, I’ve only had to use it a few times. Â The last time I used it – before this bike accident – was on my honeymoon when I stupidly wiped my glasses using a cloth that had some sand on it. Â It ended up scratching the lens and bothered me so much that I needed to get the glasses replaced. Â That cost me $80, which was easily covered by the funds I had squirreled away from myself over the years.
Does it stink that I had to buy new glasses? Â Sure, but it stinks less when you’ve already saved for it.
Why Create A Stupid Mistakes Fund?
Most stupid mistakes won’t bankrupt you. Â For the most part, you’ll probably be able to cover it with your regular cash flow. But stupid mistakes have a way of messing with our goals. Â For most people, a stupid mistake happens, and then suddenly, they might find themselves a little bit behind on whatever they were trying to achieve that month. Then, before they know it, some more stupid mistakes happen, and the cycle continues. Â Life happens.
The nice thing about a stupid mistakes fund is that it gives you a little extra cushion. Â You won’t have to mess with your regular cash flow because you’ll already have money saved away for the situation. Â And if you don’t need the money, great! Â It means you’ve got cash on you now.
The opportunity cost of saving this money isn’t high either. Â We’re not saving thousands into our stupid mistakes fund. Â I save just a few hundred bucks a year – just enough to cover the few mistakes I make in a year. The cost of not investing that money isn’t high.
You Won’t Notice You’re Saving Small Amounts
The other advantage of a stupid mistakes fund is that it can be set up without you even noticing it. Â I save just $25 per month into my stupid mistakes fund. Â For most people, I’d recommend saving somewhere between $25 and $100 per month, depending on how much you want to save and how many mistakes you tend to make in a typical year.
$25 or $50 per month isn’t really that much money. Â Most of us spend more than that in a week just going out to eat lunch. Â If you just automatically save a few bucks a month, I promise that you won’t even notice it.
It’s Easy To Set Up Your Stupid Mistakes Fund
I set up my stupid mistakes fund using my Capital One 360 account. All I did was set up a sub-account labeled “Stupid Mistakes Fund” and then every month, Capital One automatically withdraws $25 from my checking account. I’ve been doing it for years without ever noticing the money leaving my bank account.  You could do this with pretty much any online bank, but I prefer using Capital One 360 just because it lets me make sub-accounts really easily.  You can easily set up your stupid mistakes fund in just 5 or 10 minutes.
There’s some comfort in knowing that I have a little money set aside to cover these type of dumb mistakes. It takes no time to set up and it’s a nice way to make sure that I don’t ever fall behind in a month.
You’re going to make stupid mistakes – that’s a guarantee. Â You might as well pay yourself a little money each month so that you can cover those stupid mistakes when they happen.
Jasper Stojanovski says
Will you stop making contributions to your stupid mistakes fund once it has reached a certain threshold—so you can increase your investment contributions?
Financial Panther says
At the end of each year, I pull out any excess funds and use them for other stuff. I do that with my other short term goals as well.
R says
i’d be interested a recommend article on best/easiest banks (or apps) for use with sub-accounts. Highlighting features you’ve found benifitial would be advantageous as well. – ( (planning to put your suggested savings goal/practices to use after locating a service I am pleased with.)
-appreciatively, R
Financial Panther says
Best bank for sub accounts is definitely Ally bank. Discover is also good. Capital One 360 used to be my go-to one, but they changed their app now and it’s crappier than it was before, so I’ve actually recently switched over to using Ally as my primary sub-savings account bank.
Darcie says
You’re a panther–didn’t you land on your feet?
Financial Panther says
Landed on my back, unfortunately!
Christine Schwalm Design says
I have one of those. I call it the “Oh crap” account. It takes $10/week and puts it towards things like parking tickets (rare, but expensive!), replacing my cell phone screen, etc. It allows me to move on more quickly from the stupid mistakes instead of dwelling on them. I used to fixate on a parking ticket and now I grit my teeth and pay it faster–which avoids fees!
Financial Panther says
That’s terrific! And it’s nice having that little buffer. 10 bucks a week is so little no one will notice if being squirreled away. It’s perfect to cover those stupid mistakes.
Keith "Shin" Schindler says
Awesome post!
Man, I wish I’d known about this a long time ago. I’m currently paying what Dave Ramsey calls a “Stupid Tax.”
Sharing this one, for shore!
Financial Panther says
Thank Shin! I’ve definitely paid plenty of stupid tax over the years.
Pete McPherson says
I prefer “stupid mistakes fund” sooo much more than “emergency.”
Enjoyed it FP 🙂
Financial Panther says
Thanks Pete!
The Grounded Engineer says
Glad you both are ok! In addition to your stupid mistakes fund, do you also have an emergency fund? If so, why don’t you use that instead?
Financial Panther says
I do have an emergency fund, but I like to stick to real emergencies for that. My stupid mistakes fund is more for the little things that happen in life.
tedd says
Same as emergency fund? But I like it more as stupid mistakes fund!
Matt says
I classify that into my emergency fund as well. I recently had a stupid mistake problem where I ended up spending $435 on something that I didn’t even need to actually spend it on. Poof! It’s gone! :\
Financial Panther says
Ouch!
Dave @ Married with Money says
Whoops! Those MN trails are awesome but can be busy and dangerous sometimes. Glad everyone came out unscathed.
I kind of like this idea, though I feel like I would stop contributing to it once it got to a certain size. At some point I’d rather have my money doing something else. Like, after I have $500, just keep it there.
Still, an interesting concept 🙂 Thanks for sharing!
Financial Panther says
Thanks Dave. Yeah, depending on how much you save into the fund, take out the extra and use it for something else. Ramit Sethi says that too – he saves $100 a month into it, then takes out the extra at the end of the year for whatever he wants. Since I’m saving pretty little into it, it never gets too big.
Mrs. Adventure Rich says
This is such a great idea! There are so many little “oops” moments that can lead to some expensive consequences. A Stupid Mistakes Fund would certainly come in handy!
Financial Panther says
The nice thing is that your stupid mistakes hopefully shouldn’t be too expensive. Easy enough to just set aside a tiny amount each month that most of us won’t even notice.
MML says
Stupid mistake fund is actually an excellent idea, which we never thought of.
Usually our regular cash flow is able to handle any stupid mistake, which (touch wood!) does not happen too often.
But to some people, it can have a significant impact on their finances.
Our closest equivalent to stupid mistake fund is car maintenance fund, as over the years, our average expenses on auto maintenance comes to around $500 a year.
Financial Panther says
That $500 per year is something that’s easily taken care of if you divide it out over 12 months – then it pretty much seems like nothing. I’d think that’s more of an expected expense though. I tend to use my stupid mistakes fund for things that are really just stupid things I did.
