Sinking Funds: What They Are and Which Categories to Start With

The short answer

A sinking fund is money you set aside a little at a time for a cost you know is coming, like car insurance, holiday gifts or school supplies. Divide the cost by the months you have left, save that amount each month, and keep it separate so you don’t spend it by accident. Saving automatically and checking your progress makes it easier to keep going. [1]

Sinking fund vs. emergency fund

An emergency fund is for unplanned expenses, like a car repair or a medical bill. [1] A sinking fund is for costs you can plan for. You know they’re coming, even if they don’t arrive every month.

Having both helps. A sinking fund keeps predictable costs from eating into your emergency savings.

Common sinking fund categories

Start with the bills and expenses that come up once or twice a year. Look back at last year’s bank statements to find them.

Home and car

Family and kids

Seasonal

Personal

You don’t need all of these. Pick the two or three that have caught you off guard before.

How to set one up

  1. Name the goal. A specific goal helps you stay motivated. [1] “Car insurance renewal, paid in full by June” works better than “car stuff.”
  2. Do the math. Divide the amount by the number of months until it’s due. That’s your monthly savings target.
  3. Add it to your budget. You can list savings as one of your monthly expenses. [3] See our guide on how to make a budget and stick to it.
  4. Pick a consistent amount. Aim for a specific amount each payday or month. If you can sometimes add more, you’ll reach the goal faster. [1]

Where to keep it

Keep the money somewhere safe that you won’t be tempted to spend. [1] The CFPB lists options for emergency savings that also work here: [1]

Some people keep one savings account and track each fund on paper. Others open separate accounts. Either can work. Check with your bank about fees before opening new accounts.

Make it automatic

Setting up a recurring transfer from checking to savings is one of the easiest ways to save consistently. [1] Keep an eye on your balance so the transfer doesn’t cause an overdraft fee. [1]

Getting a tax refund or a cash gift? Putting some of it into a fund can give you a quick head start. [1]

Track your progress

Checking your savings regularly, whether through a balance alert or a running total on paper, can keep you encouraged. [1] When you hit a goal, celebrate it, then set the next one. [1]

The Budget Tracker printable is one way to keep your totals on paper. For more money basics, visit the Budget Hive.
