Sinking funds: What they are, examples and top accounts to start one

You’ve probably had a sinking fund before and just didn’t realize it.

Sinking funds are extremely useful to pay for large, upcoming expenses that would otherwise drain your checking account or require you to borrow.

What is a sinking fund?

A sinking fund is money you’ve set aside for a purchase or expense you know will happen. It is often used for semi-annual or annual expenses, such as vehicle maintenance, holidays or taxes.

The purpose of a sinking fund is that you’ll have saved for an upcoming expense, and it won’t ruin your monthly budget. For example, say you have to pay $1,000 for new tires. If you don’t have that cash on hand, you may have to use a credit card, which can lead to debt and high interest payments. If you had created a sinking fund where you saved $85 each month for a year, you’d have the cash in hand and wouldn’t have to use credit or pull it from your emergency fund to pay for the tires.

Sinking funds vs. emergency funds

Emergency funds are savings designed to cover living expenses in — you guessed it — an emergency. They differ from sinking funds, which are designed and used for a specific upcoming expense. Emergency funds are used as a last resort, and in most cases, these funds are otherwise left alone.

Sinking fund categories and examples

Sinking funds are a practical way to manage your finances and avoid financial strain by setting aside money for a future expense. Some common sinking fund examples include:

How do I seperate my sinking funds?

The bucketing method is a great and easy way to sort your sinking funds. Bucketing is a simple budget method that separates your savings into “buckets,” each designed for a specific goal. When you get paid, you can allocate a specific dollar amount to be added to each bucket.

You can do the bucketing method with physical cash, such as separating the money into envelopes or jars. The downside of bucketing cash outside of a savings account is that it will not earn interest. If you want to earn interest on your funds, there are savings accounts with bucketing features so you can sort your savings buckets digitally.

4 top accounts for sinking funds

A savings account is one of the best places to put a sinking fund. Savings accounts earn interest through an annual percentage yield (APY), which means your sinking fund will grow passively. The average interest rate for a savings account is 0.46%, according to the FDIC. Plenty of accounts have significantly higher APYs, called high-yield savings accounts.(1)

Bottom line

Sinking funds should be kept separate from your emergency fund, if possible. You don’t want to be using your emergency fund for regular expenses, vacations or regular vehicle maintenance. Sinking funds can help by not throwing your monthly budget off. Paying for things like car registration, tuition and Christmas presents out of pocket might require a credit card, which can lead to high-interest debt.

Frequently asked questions

Are sinking funds worth it?

Sinking funds are a great budgeting tactic and can definitely be worth your time. They are fantastic for expenses like vacations, Christmas gifts, car maintenance or high-cost obligations that would strain a monthly budget. You can integrate your sinking fund goals into your regular budget so when the time comes to use the sinking funds, it doesn’t drain your checking account, you don’t have to borrow and you can leave your emergency fund alone.

Can you have too many sinking funds?

While you can create as many sinking funds as you want, it’s possible to create too many. For example, if you want 10 different sinking funds but can only afford a $10 monthly contribution to each, the sinking funds will grow slowly and may not be large enough to cover the expenses you’re saving for. Additionally, you’ll have to manage all the various sinking funds, which can feel overwhelming.

Figure out your monthly budget to see how many sinking funds you can create. For example, if Christmas is six months away and you want to save $1,000, you’ll need to save around $167 per month. If you still have extra money to afford another sinking fund, you can create another and so on.
