Why should you have a sinking fund?

Benefits of a sinking fund

A sinking fund is an account where you save money every month to be spent for large amounts like insurance payments, school annual fees or festival gifts. The sinking fund smoothens out your monthly budget since you already have the money with you whenever you need it.

Why should you review your sinking fund regularly?

A regular reader posted this query:

When I plan for Sinking fund, should I consider current value of expenses or some inflated expenses. For instance last year I have started my kids school fee as 65K and saved Sinking fund for 1 year, now the fee is hiked to 72K.

Likewise other expenses like insurance premium, summer vacations all are raising so far within a year . Should we add some inflation to plan for savings in sinking fund ?

Both of these questions require that your sinking fund be reviewed at least annually or as soon as one expense increases. We will now discuss how to review the sinking fund so that you can use it when the costs of your goals go up.

We will now describe the steps for reviewing your sinking fund one by one.

Step 1: Assess inflation factors per goal

For each of the goals in your sinking fund, assume an inflation factor at which the goal grows. One example is to assume that your health insurance premium can grow by 10% every year. If you don’t have inflation numbers, assume 7% which means that the cost of the goal doubles in 10 years.

Step 2: Calculate the new updated value of the goal

Once you have the inflation value, then

New Goal Value = Old goal * (1 + Inflation)

For example, if your health insurance premium is ₹30,000 and that increases by 10%, then the new premium is ₹30,000 * 1.1 = ₹33,000.

If you already know the new value of the goal, take the new value. In the reader query above, the school fee is hiked to 72k from 65k.

Step 3: Add or remove goals

If your child starts school next year, or you just took a new insurance policy, then you can add the new goal to the list.

Add or Remove goals

If you are using this spreadsheet tool to manage your sinking fund, and you should if you have not already, then check out this guide: How to make sure that you always have money for short-term goals?

Step 4: Add up the new goal values

How to calculate sinking fund contribution

Once you have the new values or the inflations, just add them up and divide by 12 to get the amount you need to invest per month.

Step 5: Choose a review frequency

For most goals, a yearly review is fine. If you already have the new goal value, you can simply update the new value now instead of waiting for the next annual review. Unless you are adding or removing goals, the change in the monthly value will not be very different from your current amount.

Step 6: Adjust the monthly investment amount

You can easily update your SIP amount if you are using a debt mutual fund to save the new amount. If you are saving a fixed amount via recurring deposit or fund transfer standing instruction, then you can update the amount by changing the RD or standing instruction.
