The 30% Rule: How To Consistently Control Your Spending

Wednesday, April 07, 2021 12:44 PM | Taylor Venanzi

For almost all of us, there is always something new we could spend our money on. Do you need a Peloton? Probably not. Do you want one? Most certainly. Unfortunately, very few of us get to a point in which our spending habits do not have a material impact on our financial future.

With the understanding that there are unlimited purchases we could make, it is critical that we formulate a savings plan that we can consistently implement over a long period of time.

This is where the 30% rule comes into play.

Lifestyle Inflation

Before we dig into the 30% rule, we need to understand the root of the problem as it relates to our saving and spending habits.

Lifestyle Inflation: Lifestyle inflation refers to the concept that as income rises, spending tends to rise with it.

An Example: After graduating from college, you move in with two friends in a three bedroom apartment paying $1,000 per month in rent with a salary of $60,000. Two years later, you get a promotion and now make $100,000. With your new salary, you move into a one bedroom apartment paying $1,800/month in rent. While it may seem like you are better off, you are now spending roughly 22% of your gross income on rent per year (an increase from 20% before the raise).

As you can see, lifestyle inflation can sneak up on you rather easily. Our previous example used an increase in rent to illustrate the point. Think about all of the other things that could cause your expenses to rise over time:

The list of things that can cause your expenses to rise is truly endless. So what should you do about it?

The 30% Rule

The 30% rule is not a new concept. There are a few variations, but the objective is the same:

Have a plan for how much you are going to spend as a percentage of your income.

 A general rule of thumb is to dedicate 30% of your gross income to variable/discretionary spending (i.e. eating out, social memberships, gifts, vacations, etc.). Truth be told, 30% is a bit high (but it is a start nonetheless).

Here is a breakdown of a sample spending/saving template:

Now that you understand how this all works, why do it in the first place?
