What is a rainy day fund?

A rainy day fund is money set aside for small, predictable but irregular expenses that can pop up at the worst times. Unlike your regular checking account, this fund acts as a cushion so you don’t swipe your credit card into oblivion.

What’s the difference between a rainy day fund vs emergency fund?

A rainy day fund is for the “ugh, really?” costs. An emergency fund is for the “oh no, how am I going to survive this?” situations. Rainy day = $200 for new brakes. Emergency = 6 months of rent because you lost your job. Both matter. We break down emergency funds here, so you’ll know when to use one vs. the other.

Expenses your rainy day fund should cover

Typical expenses savings for a rainy day should cover include:

• Car repairs or new tires

• Home repairs like a leaky faucet or busted fridge

• Minor medical bills or prescriptions

• Pet care costs like an emergency vet visit

• School or work-related fees you didn’t see coming

How much money should be in a rainy day fund​?

There’s no scientific answer to this, but one good guideline is to set aside $500 at the low end; from there you can set as high a goal as you want, like 5% of your annual income or even more. That’s a manageable rainy day fund percentage that covers most small surprises without making you feel like you need a second job.

You don’t need to save the whole thing right away; just begin with whatever amount feels doable, even if it’s $10 a week. The key is consistency, because those small deposits will quietly snowball into a solid cushion over time.

Where should you keep your rainy day fund?

Not sure where to save for a rainy day? Accessibility and safety are the name of the game. Here are some of your best options for where to save money for a rainy day:

High yield savings accounts

A high-yield savings account is the gold standard for a rainy day savings account. It keeps your money safe, earns more interest than a regular savings account, and is easy to dip into when your car makes that “uh-oh” sound.

Investment accounts

If your rainy day savings already has a solid base, you can stash a portion into low-risk, automated investment accounts. Just keep in mind: investments carry some risk. They’re not a savings account, and you could lose some or all of your funds. So this shouldn’t be your only rainy day stash.

Money market account

A money market account is like a hybrid between checking and savings: safe, earns some interest, and often comes with check-writing privileges. It’s another solid option for money saved for a rainy day.

Smart tips on how to start a rainy day fund

Rainy day money gives you flexibility when life throws you an expensive curveball. Here’s how to get rolling:

Take a look at your budget to find extra cash: Start by looking at your monthly income and expenses. Look at your current budget and check for small areas you can trim like eating out less often, or adjusting utility usage. Even $20 to $50 a month redirected into savings adds up over time.

Set a small, achievable goal first: Instead of aiming for $1,000 right away, start with $100 or $250. Hitting smaller milestones gives you momentum and keeps you motivated.

Treat your rainy day fund like a bill: Automate a transfer to your rainy day account every payday, just like rent or utilities. If you don’t see the money, you won’t be tempted to spend it.

Use a separate, hard-to-reach account: Open a savings account at a different bank (or a digital bank) so it’s not mixed in with spending money. Out of sight, out of mind.

Funnel windfalls into it: Tax refund? Birthday money? A side gig payout? Put at least half into your fund before you can spend it.

Round up your purchases: Use a bank or app that rounds up transactions to the nearest dollar and sends the spare change to your rainy day account. It’s painless but adds up quickly.

Trim one small expense: Cancel a subscription you rarely use or make coffee at home twice a week. Redirect that $5 to $20 straight into your rainy day fund.

Give your rainy day fund a purpose: Label the account something motivating like “Peace of Mind Fund” or “No-Stress Money” so you’re reminded why you’re saving.

Keep Calm and Save On

Saving money for a rainy day isn’t glamorous, but it’s freedom in disguise. Whether it’s saving $20 a week, rounding up your coffee purchases, or putting tax refunds to good use, those dollars create peace of mind. Pair it with an emergency fund, and you’ve got financial armor for both drizzles and downpours.
