Sinking Funds: The Budgeting System Nobody Taught You

The quiet system that ends the era of 'where did all my money go' and turns predictable expenses into a non-event

Chile, let me tell you about the year I cried over a car repair.

My check engine light came on in October. The mechanic told me it was going to be $400. I had the money — barely — but it was earmarked for Christmas. And in that moment I had to choose between paying for the car and having a normal Christmas with my family. I chose the car. I sat in the parking lot afterwards and cried.

Not because $400 was the end of the world. But because I had known, on some level for months, that my car was making a weird sound. I had known the holidays were coming. I had known a hundred things, and somehow I still got caught out.

That's when learned about sinking funds. And listen — once you understand them, you will be furious that nobody told you sooner.

What sinking funds actually are

A sinking fund is a separate pot of money you save up over time for a specific expense you know is coming. That's the whole concept. It's not an emergency fund. It's not savings. It's not investing. It's money set aside on purpose for a specific predictable thing.

Here's the magic part. Big expenses that feel like emergencies are usually not emergencies. They're predictable. Christmas comes every December. Your car needs maintenance every year. Your insurance premium comes due. Your kid needs school supplies. Your vet visit is annual. None of these are surprises.

They only feel like surprises because we don't plan for them.

Sinking funds turn those 'surprises' into a non-event. By the time December hits, the Christmas money is already there. By the time the car needs new tires, the tire money is already there. You don't feel the hit because you've been gently chipping at it for months.

The math is shockingly simple

Let's say you typically spend $800 on Christmas. Instead of scrambling in December, you set aside $67 a month starting in January. Twelve months later, you have $800 sitting there waiting for you.

Now multiply that across every annual expense in your life. Car maintenance. Insurance. Holidays. Vacation. Pet care. Home repairs. Each one of them gets its own little pot, funded monthly.

December stops being financially terrifying. Your car breaking down stops being a crisis. Your annual insurance bill stops being a scramble. Everything shifts from reactive to proactive.

The 10 sinking funds every rich girl needs

This is my actual list (plus a few extra for those who may need it). Adjust to your life, but use it as your starting point.

1. Christmas and holidays. Not just gifts — the food, the travel, the parties, the work gift exchange, the tip envelopes for the doorman or the hairstylist or the babysitter. The full December tax.

2. Car maintenance and repairs. Tires, oil changes, brakes, the inevitable repair. If you own a car, you are spending money on this. Plan for it.

3. Annual insurance premiums. Some insurance can be paid annually for a discount. Save monthly, pay annually, save money.

4. Birthdays and gifts. Your sister's birthday, your mom's birthday, the wedding shower, the baby shower. There's always one. Stop being caught off guard.

5. Vacation. The trip itself, plus the dog boarding, the airport parking, the spending money. Treat it like a separate line item from your regular life.

6. Vet care. Annual checkups for your pets, plus the inevitable random thing that comes up. If you have a pet, you have this expense.

7. Home maintenance. Even renters need this for furniture replacements, appliance repairs, deposit-eating wear and tear. Owners need it for everything.

8. Taxes (if you have side income). If you make any money on the side — content creation, consulting, a digital shop — set aside a percentage every time money comes in. Future you will not be panicked in April.

9. Self-care annual costs. The dentist visit you keep skipping. The doctor's appointment. The dermatologist. The eye doctor. The annual things that aren't covered by insurance.

10. The 'I want it' fund. This is the secret rich-girl move. A pot of money labeled, specifically, for things you genuinely want but feel guilty buying. The flowers. The nicer dinner. The good purse. The spa day. Because rich life is not refusing to spend — it's spending intentionally on what genuinely makes your life better.

How to actually set this up

You don't need fancy apps or a $400 financial planner. You need two things. A separate place to put the money, and a rough monthly amount per fund.

The simplest setup is a high-yield savings account at a bank like Ally, SoFi, or Discover. Inside that one savings account, you create 'buckets' — most online banks now let you name sub-accounts. So you'd have a Christmas bucket, a car bucket, a vacation bucket, and so on. Each one gets a target amount and a monthly deposit.

Then you automate. On the day after each paycheck hits, money moves automatically from checking into each bucket. You never see it. You never decide. It just happens.

That's it. That's the whole system.

The trick to not feeling broke from doing this

Here's the part most people get wrong. They look at their list of sinking funds, add up the monthly contributions, panic at the total, and quit before they start.

Don't do that. Start small. Pick the THREE that would change your life the most right now. For me it was Christmas, car repairs, and the 'I want it' fund. That's it. I started with three.

As your income grew, I added more. The vacation fund came next. Then the pet care (when I had a dog 😞). Then the birthdays and gifts. Five years later I have a full system running, but I started with three pots and $50 a month into each.

Fifty dollars times three is $150 a month. Most women can find that. And once you've experienced what it feels like to have a $600 Christmas fund already saved up by November, you become a believer for life.

Why this is rich-girl behavior

Sinking funds are the quietest power move in personal finance. They don't look impressive. There's no app to brag about. You don't post screenshots of them on Instagram. They just sit there quietly working.

But they completely change how you experience money.

You stop dreading December. You stop dreading the mechanic. You stop dreading the dentist. You stop fighting with your partner about the unexpected bill. You stop reacting to your own life.

And that calm? That quiet, boring, my-money-is-handled calm? That is what rich actually feels like. Not flashy. Just settled. Like nothing can come at you that you're not already prepared for.

Where to go from here

This week, do this. Open your calendar and scroll through the last twelve months. Write down every 'big' expense that hit you — car stuff, gifts, vacation, holidays, insurance, vet, doctor, home repair. Add them up.

Divide by twelve. That number is what you've been getting hit with monthly without realizing it.

Now imagine that money had already been there, waiting. That's the difference between scrambling and being a woman with her business handled.

Start with three sinking funds this month. Just three. Let me know how it changes things.

Now go live your richest life and we’ll talk soon. 💋
