Sinking Funds – What Are They?!

Spread the love

Have you ever heard of sinking funds?! I know I hadn’t before starting my financial freedom journey. I only set mine up this year – and I wish I had started sooner! A sinking fund is a way to mentally and physically allocate your money so as to better protect you and your peace of mind. 

For me, I have always felt guilty about spending money. I don’t know why or where it stems from, but it’s really hard for me to buy treats, days out or anything fun! Sinking funds allow you to make small, manageable steps toward your ultimate goal in my opinion.

What is a Sinking Fund?

They are basically ‘pots’ of money that you create- either by an app on your phone, your bank or in cash. You set a goal amount and the types of funds you want to have – this is totally personalised to you as everyone has different goals and interests.

Pick an amount that you’d like to contribute to your sinking fund every month and make sure to make those monthly deposits. You can automate your savings by setting up a standing order from your main account into your sinking fund account to make this process even easier.

I have four sinking funds at the moment all set up in my Starling Bank account. You can personalise these and add photos to keep you motivated. They are called ‘spaces’ in Starling.

I know a few other banks also have these now such as Monzo and Natwest.


To work out how big your sinking fund should be, go through this process: 

  • Write down all of the costs you anticipate 
  • Estimate how much each will cost
  • Work out how many months you have to save
  • Divide the total amount by the number of months you have to save the money 
  • This is how much you need to put away each month 

Examples of a Sinking Fund

Some common known upcoming expenses include: 

  • Vehicle purchases or financings
  • Car repairs or maintenance
  • Hobbies and Interests 
  • Buying new furniture
  • Saving for Holiday
  • Holiday gifts and travel
  • Paying self-employment taxes
  • A big event, like attending a wedding or a big birthday 
  • Healthcare
  • School uniforms
  • Pets 
  • Household expenses – this includes expenses you know are unavoidable so for example if your boiler will need replacing.

These are just a few to get you started. Really, you can use a sinking fund for many other types of expenses. They are personalised and that’s the great thing about them.
