A sinking fund may help make saving for a major purchase easier. Whether you need a down payment for a house or want to pay off a credit card, it may feel overwhelming to build up the savings. And your goals may require you to save up for several months (or years) to cover the costs. Sure, you could dip into your general savings account or even tap into your emergency fund, but there may be a better option – a sinking fund. Setting up a sinking fund may help you save for one goal without impacting other financial goals.

Key Takeaways

  • Sinking funds help you save for a specific purchase or event.
  • Establish a clear savings goal and timeline to make the most of your sinking fund.
  • Keeping your sinking fund in a dedicated savings account may make it easier to track your progress.

What Is a Sinking Fund?

A sinking fund is a savings method that helps fund a specific purchase or expense by a certain date. For individuals, the term simply refers to an account and process used in saving toward a goal. The term (and practice) is commonly used in corporate environments too.Individuals may use a sinking fund to save toward a purchase like a new car or buying a home, as well as toward a future, planned expense like a wedding.

Purpose of a Sinking Fund

For individuals, a sinking fund is distinct from other saving categories you may have as sinking funds are designed to help you save for a specific purpose. Some people may choose to designate or name their sinking fund after the goal they’re saving for, such as a wedding fund. Before we dive into sinking funds in more detail, here are the definitions of other fund types, so that you understand how they differ.
  • Emergency Fund: An emergency fund covers major financial strains, such as losing your job or a medical emergency.
  • Rainy Day Fund: A rainy day fund covers smaller unexpected financial situations, such as a surprise vet bill or a broken water heater.
  • Splurge Fund: A splurge fund helps you cover spontaneous purchases, like concert tickets or a shopping spree, without impacting other financial goals.
  • Vacation Fund: A vacation fund helps you cover expenses related to travel, from hotels to airlines to meals. (Some people choose to use a sinking fund to save for a vacation. Others have vacation funds as ongoing. It’s up to you!)
It’s important to create funds that align with your financial goals. Not everyone needs to have every type of savings fund.

Benefits of a Sinking Fund

A sinking fund offers a few pros that may make saving toward your goal easier and more rewarding. Here are a few ways starting a sinking fund may help.
  • Stay motivated: Many people create a timeline for reaching their goal when using a sinking fund. It may be easier to stay motivated when you know exactly where the finish line is.
  • Reduce guilt: Many people feel guilt or have buyer’s remorse after making a large purchase without saving for it in advance. By saving ahead of time, it could make shopping (and purchasing) even more fun.
  • Plan for annual costs: If you have annual or semi-annual expenses like buying holiday gifts or insurance premiums for a house or car, a sinking fund may help you prepare for these costs and reduce stress when those purchases roll around.
  • Accommodate multiple goals: If you’re saving toward multiple goals at the same time, sinking funds may make it easier to track the progress toward each one. Even better, if your savings goals are different amounts, achieving a smaller goal may motivate you to keep saving toward bigger ones.
  • Reduce temptation: Since sinking funds help you save for a specific goal, you may be less tempted to use the money on other items or purchases. It may also make you less likely to dip into other funds (like your rainy day fund) to cover a large purchase.

Downsides of a Sinking Fund

While sinking funds offer numerous benefits, keep in mind that you need to be strategic with the amount you allocate to it. If you don’t maintain a balanced budget, you could put other financial goals, like reducing debt or saving for retirement, at risk.You also need to avoid dipping into the fund for other reasons, such as splurging on the newest phone, if you want to reach your goal on time.

How to Create a Sinking Fund

Creating a sinking fund could be easy if you follow these steps.

Step 1: Choose Your Goal

Before you start your sinking fund, decide what goal or goals you’re saving for. Once you know what you’re saving for, decide how much you need for this purchase and create a timeline for reaching this goal. When creating your timeline, set a realistic date based on the size of the goal. For example, it may take you longer to save enough to pay off your credit card debt than for the down payment on a car. You may want to break your larger goal into smaller milestones. This could help you stay motivated and make building your savings easier in the long run.

Step 2: Work Your Sinking Fund into Your Budget

As with any savings goal, you need to make regular contributions to the fund in order to reach your goal. The easiest way to do that could be making your sinking fund part of your monthly budget.Take a look at your savings goal and your timeframe to determine how much you need to contribute each month to help you reach your goal. Say you’re trying to save $20,000 for a down payment on a home in the next two years. That means you want to put $10,000 annually, approximately $834 per month, into your sinking fund. Once you determine how much you need to save, examine your budget and see where you could adjust current spending to meet this goal. This might mean cutting back on less important expenses (like pressing pause on nightly take-out). Of course, you may still want to splurge during this time, but that’s why you have a splurge fund!

Step 3: Decide Where to Store Your Sinking Fund

Just because you could keep your sinking fund in cash in an envelope doesn’t mean you should. You may want to put that money to work. The easiest way to do that could be by keeping it in a high-yield savings account that earns a competitive rate, expressed as Annual Percentage Yield (APY).Depending on when you need the funds, you may consider opening a certificate of deposit (CD). CDs may have higher rates available than savings accounts in exchange for locking your money away for a set term. Keep in mind that many CDs only let you contribute money when you open the account, so if you plan to make regular contributions to your sinking fund, a CD may not be the best choice. That said, you could use the CD bullet strategy, where you purchase multiple CDs over time that have similar maturity dates. High-yield savings accounts, on the other hand, are more accessible and let you make ongoing contributions whenever you have the money to do so.Take your time and compare your savings account options to find an account that helps you reach your goals and meets your needs. Compare your options by reviewing rates, any potential fees, and look for accounts that are FDIC-insured to make sure your money is safe.

Final Thoughts

Creating a sinking fund may make it easier to save for major goals or purchases and plan ahead for future purchases. By keeping your money in a high-yield savings account, your funds may grow faster and speed up your savings. Whether it’s for your dream home, a new car, or paying off debt, using a sinking fund to set money aside regularly may help you achieve your financial goals. Looking for a home for your sinking fund?
