SOME CARD INFO MAY BE OUTDATED

This page includes information about these cards, currently unavailable on NerdWallet. The information has been collected by NerdWallet and has not been provided or reviewed by the card issuer.

In a given year, you likely have expenses that you know are coming — holiday gifts, the family vacation you take every summer, home improvement costs or maybe membership renewals. But just because these costs are predictable doesn’t mean you’re always prepared.
If you are pulling from your emergency fund or using a credit card to cover predictable costs, you might consider using one or more “sinking funds.”
A sinking fund is a savings account dedicated to a particular expense that you fund gradually through regular payments. Sinking funds often have a deadline associated with them, but not always.
You can add sinking funds to your budget for expenses that come at the same time each year or to plan a big purchase you want but don’t necessarily need — like a new couch for your living room or that piece of exercise equipment you’ve been eyeing for months.
Either way, sitting down with your calendar and noting upcoming expenses is a good way to get ahead of predictable costs and prevent unwanted debt or dipping into your emergency fund.

How do sinking funds compare with other savings accounts?

A sinking fund is different from other kinds of savings accounts — like an emergency fund or a traditional savings account — in a few ways.
An “emergency fund is for true emergencies, and then your sinking fund is for a dedicated, expected planned purchase in the future that we know is coming,” says Kumiko Love, an accredited financial counselor and creator of The Budget Mom, a website with resources to help people create and stick to a budget.
Because they have different purposes, separating sinking and emergency funds is wise.
Keeping sinking funds separate from your emergency fund “ensures you don’t accidentally use those funds for the wrong purpose and helps you stay consistent in your budget,” says Mary Kamelle, marketing manager at the nonprofit credit counseling agency American Consumer Credit Counseling (ACCC).
Sinking funds also differ from traditional savings accounts because they have a specific goal and target deadline. That helps you track progress on multiple goals while putting all your savings into one large pot can get confusing and make you lose sight of your goals.
Nerdy Perspective
My husband and I opened a high-yield savings account with Ally years ago and still keep our joint savings there. One thing I love about Ally is the savings “buckets” feature — we’ve set up sinking funds for emergencies, home repairs, our child’s school tuition, vacations, car costs and holidays. It’s so nice to open the app and instantly see how much we’ve saved for each goal without doing any mental math.

The strategy behind sinking funds

Most sinking funds have a target date, and with this deadline “comes a strategic way to plan responsibly for that purchase,” says Love, who has 13 sinking funds. For example, if homeowners association fees are due in May each year, you can start planning ahead to have the cash on hand.
Let’s take the HOA example: If annual dues are $500 and you have six months to save, you need to put about $83 a month in your sinking fund. Or roughly $42 per paycheck if paid biweekly. Or $21 a week. As you can see, it’s highly customizable.
You can also use windfalls like tax refunds or gift money to boost these accounts and reach your goals faster. Just keep in mind: Put money into sinking funds based on priority and necessity. Required fees should come before wants.
If you have leftover money in a sinking fund, either keep it there so you’re ahead of the game for next year, reallocate it to the next priority or pad your emergency fund, if needed.

Can you have too many sinking funds?

The trick with sinking funds is striking the right balance. You might find that having multiple savings buckets to fund with each paycheck feels overwhelming. Setting up autopay might be one way to help streamline things. Some banks offer customers the ability to customize savings buckets within their accounts.
Figuring out your top few priorities and setting up sinking funds is a good start. You can always add more sinking funds if you find this strategy works for you.

Are sinking funds right for you?

This is a low-risk strategy for saving for expected future costs. “I believe sinking funds can be for anybody no matter where they are with their finances,” Love says.
Managing sinking funds also “trains us to create healthy habits in our lives to prepare for the things that are putting us in debt,” Love says.
