Sinking Funds, Explained: How to Stop Dreading Summer’s Big Expenses

Every summer, it happens.

The wedding invitations arrive.

The kids’ camps need to be paid.

Someone suggests a weekend at the lake or a road trip with friends.

Then suddenly you’re looking at your bank account thinking, How is all of this happening at once?

The funny thing is, none of these expenses are actually surprises.

You knew the weddings were coming.

You knew your kids would want to go to camp.

You knew summer would eventually arrive.

So why does it still feel so stressful?

Because knowing an expense is coming isn’t the same as preparing for it.

That’s where one of my favourite financial tools comes in.

It has a slightly clunky name, but don’t let that fool you.

It’s called a sinking fund, and it can completely change how you experience predictable expenses.

What is a sinking fund?

A sinking fund is simply money you set aside a little at a time for an expense you already know is coming.

Instead of scrambling to find hundreds or thousands of dollars all at once, you slowly build the money in advance.

No complicated spreadsheets.

No fancy investing strategy.

Just a simple plan that allows your future self to breathe a little easier.

Here’s what it looks like

Let’s say you’ve got about $1,200 of summer expenses coming up.

Maybe it’s a couple of weddings, camp fees, and a weekend away.

If you start putting money aside six months before summer, that’s only $200 each month.

By the time those expenses arrive, the money is already waiting for you.

No scrambling.

No reaching for the credit card.

No wondering how you’re going to make it all work.

The best part isn’t the money itself.

It’s the feeling.

An expense that used to create stress becomes something you simply pay for and move on.

How to create a sinking fund

It doesn’t have to be complicated.

1. Look ahead.

Think about the next six to twelve months.

What expenses do you already know are coming?

Birthdays.

Vacations.

Holiday shopping.

Back-to-school costs.

Vehicle maintenance.

Annual insurance payments.

Most of the expenses we call “unexpected” actually show up every year.

2. Do the simple math.

Add up what you expect to spend.

Then divide that amount by the number of months until you’ll need it.

That’s your monthly savings goal.

3. Give it a home.

Open a separate savings account. Giving each goal a name like “Summer Adventures” or “Holiday Fund” makes it much easier to stay motivated because you can actually see what you’re saving for as the balance grows and you know it’s coming up.

4. Automate it.

Set up an automatic transfer each payday.

Then let the system do the work.

Just like taxes come off your pay before you have a chance to spend them, your future plans can too.

Why this works

One of the pillars of my Financial Alignment Method is preparing for what’s ahead.

When you know an expense is coming, your money should know it’s coming too.

That’s what creates financial alignment.

Instead of reacting every time life happens, you’ve already made space for it.

That shift changes everything.

You stop asking, “How am I going to pay for this?”

And instead find yourself saying, “Oh right…I’ve already planned for that.”

That’s a very different feeling.

Start with just one

You don’t need a dozen sinking funds.

You don’t need the perfect system.

Just choose one expense you’ve been quietly worrying about.

Maybe it’s Christmas.

Maybe it’s your next vacation.

Maybe it’s your child’s activities this fall.

Set up one automatic transfer.

Even if it’s only $25 or $50 each payday.

Small, consistent actions have a way of making life feel much less overwhelming.

That’s what financial wellness is all about.
