Unexpected expenses aren't always unexpected—you just didn’t plan for them.
That’s where sinking funds come in.
A sinking fund is one of the most powerful tools for financial stability. It helps you avoid debt, reduce stress, and stay ahead of “surprise” costs.
In this post, we’ll break down what sinking funds are, how they work, and how to set them up—even on a tight budget.
What Is a Sinking Fund?
A sinking fund is money you set aside gradually for a specific future expense.
Unlike an emergency fund (for true surprises), sinking funds are for planned-but-irregular costs like:
-
Car maintenance
-
Holiday gifts
-
Insurance premiums
-
Travel or vacations
-
Back-to-school expenses
Think of it as saving in advance, on purpose.
Why Sinking Funds Matter
If you’ve ever had to:
-
Put Christmas gifts on a credit card
-
Take out a loan for car repairs
-
Stress about an annual insurance bill…
Then you need a sinking fund.
✅ It keeps you from going into debt
✅ It smooths out your budget
✅ It puts YOU in control of your money
Sinking Funds vs. Emergency Funds
| Sinking Fund | Emergency Fund |
|---|---|
| For expected expenses | For unexpected expenses |
| Known amounts & due dates | Unknown timing & amount |
| Examples: holidays, taxes | Examples: medical bills, job loss |
| Multiple categories | Usually one single account |
💡 You need both—but start where you can.

How to Start a Sinking Fund in 4 Simple Steps
1. Choose Your Categories
Look at your year ahead and pick 3–5 key areas to start with.
Ask: What expenses do I always forget about until it’s too late?
2. Set Your Goal Amounts
Estimate the total you’ll need.
Example:
If you want to save $600 for Christmas and it’s 6 months away → Save $100/month.
3. Open a Separate Savings Account (Optional)
You can:
-
Use separate bank accounts for each fund
-
Use one account + a spreadsheet or budgeting app to track categories
Apps like YNAB, Qube, or Goodbudget make this super easy.
4. Automate and Budget Monthly
Add your sinking fund contributions as line items in your monthly budget—just like rent or groceries.
💡 Even $10–$50 per category makes a difference over time.
