What Is a Sinking Fund?
and Should You Have One?
Car repairs. Holiday gifts. A new refrigerator. Summer camp. Annual insurance premiums.
These expenses may not show up every month, but that doesn’t necessarily make them unexpected. In many cases, you know they’re coming—you just may not know exactly when or how much they’ll cost.
That’s where a sinking fund can help.
A sinking fund is money you intentionally set aside over time for a specific future expense. Instead of waiting for a large bill and scrambling to cover it, you save a little at a time so the money is ready when you need it.
Think of it as giving tomorrow’s expenses a place in today’s budget.
How Does a Sinking Fund Work?
The concept is simple: Identify an upcoming expense, estimate how much you’ll need and divide that amount by the number of months you have to save.
For example, suppose you expect to spend $1,200 on a family vacation next summer and have 10 months to save. Setting aside $120 a month would get you to your goal.
Or maybe you know your car will need about $600 in tires and maintenance within the next six months. Saving $100 a month can help you cover the expense without putting the entire bill on a credit card.
Sinking funds can be especially helpful for expenses such as:
- Holiday gifts and celebrations
- Vacations and travel
- Car repairs and maintenance
- Home repairs and improvements
- Annual insurance premiums
- Back-to-school shopping
- Property taxes
- Pet expenses
- Weddings and special occasions
- Technology or appliance replacement
You can create one sinking fund or several, depending on your needs and budget.
“Some of the expenses that can throw our budgets off the most aren’t really surprises—we know the holidays are coming, the car will eventually need work or something around the house will need to be replaced,” says Linda Halleran, Community Engagement Manager at Town & Country Federal Credit Union. “A sinking fund lets you prepare a little at a time, so those expenses can be much easier to manage when they arrive.”
Sinking Fund vs. Emergency Fund: What’s the Difference?
Although both involve saving money, a sinking fund and an emergency fund serve different purposes.
An emergency fund is designed for expenses you didn’t see coming, such as a sudden loss of income, major medical expense or urgent home repair.
A sinking fund is for expenses you can reasonably anticipate.
If your 15-year-old furnace suddenly stops working, that may be an emergency. But if you know your aging furnace will probably need replacing in the next few years, starting a sinking fund now can help turn that future emergency into a planned expense.
Ideally, your savings strategy can include both: emergency savings for the unexpected and sinking funds for the expenses you know are likely to come your way.
Why Sinking Funds Can Make Budgeting Easier
One of the biggest benefits of a sinking fund is that it can smooth out your spending.
Most budgets look manageable until a $700 car repair, $1,000 holiday season or $2,000 home project lands in the middle of an otherwise normal month. By spreading that cost across several months, you can make larger expenses easier to absorb.
Sinking funds may also help you rely less on credit cards or loans. When the money is already saved, you can pay the expense without adding new debt and potentially paying interest.
There’s also a psychological benefit. Knowing that you already have money set aside for an expense can take some of the stress out of spending it. A $500 car repair may still be frustrating, but it can feel much more manageable when you have $500 sitting in your “car expenses” fund.
How to Start a Sinking Fund
Start by looking ahead over the next six to 12 months. What larger expenses are likely to come up?
Then prioritize. You don’t need a separate fund for every possible expense. Pick one or two expenses that are most important or most likely to put pressure on your budget.
Next, set a target amount and timeline. If you need $900 nine months from now, your monthly savings goal is $100. If that doesn’t fit your budget, adjust the goal, extend the timeline or look for ways to reduce the expected expense.
Consider keeping sinking fund money separate from your everyday checking account. Depending on how you manage your money, you might use separate savings accounts or savings categories to keep your goals organized.
Finally, consider automating your savings. Setting up an automatic transfer each payday or each month can help you make steady progress without having to remember to move the money yourself.
What If You Can Only Save a Little?
You don’t need to fully fund every future expense for a sinking fund to be worthwhile.
Suppose you expect your next set of tires to cost $800, but you’re only able to save $40 a month. After 10 months, you’ll have $400. Even though you haven’t saved the entire cost, you’ve cut the amount you’ll need to come up with later in half.
The goal isn’t perfection. It’s preparation.
Should You Have a Sinking Fund?
For many households, sinking funds can be a useful addition to a monthly budget—especially if irregular expenses tend to throw your finances off track.
Take a look at the past year. Which expenses caught you financially unprepared even though, looking back, they weren’t completely unexpected? Those expenses may be good candidates for sinking funds.
Start small, choose a goal and begin setting aside what you can. Over time, sinking funds can help turn those “How am I going to pay for this?” moments into expenses you’ve already planned for.
Because sometimes the best way to handle an unexpected bill is to recognize that it wasn’t entirely unexpected after all.
