The 50/30/20 Rule Of Thumb For Budgeting

You’ve reviewed your spending and created a budget, and now you know exactly how much you spend on your home, your car, discretionary spending, and how much you divert to your Pensions for retirement. That’s all good, but what about your other savings, such as for an emergency? How does your financial allocation compare to the amount you should ideally spend and save?

Harvard bankruptcy expert Elizabeth Warren – U.S. Senator from Massachusetts and named by Time magazine as one of the 100 Most Influential People in the World – coined the “50/30/20 rule” for spending and saving with her daughter, Amelia Warren Tyagi. They co-authored a book in 2005: “All Your Worth: The Ultimate Lifetime Money Plan.” So how does the 50/30/20 plan work? Here’s how Warren and Tyagi recommend you organize your budget.

Step One: Calculate Your After-Tax Income

Your after-tax income (if you pay tax) is what remains of your salary after taxes are taken out, as well as Medical Insurance (if applicable). If you are an employee with a steady income, your after-tax income should be easy to figure out. Look at your payslips. If health care, retirement contributions, or any other deductions are taken out of your pay, add them back in.

If you are self-employed, your after-tax income equals your gross income less your business expenses, such as the cost of your laptop or airfare to conferences, as well as the amount you set aside for (future) taxes. You are responsible for remitting your own tax payments to the government because you don’t have an employer to take care of it for you. Just remember that being self-employed means that you must also pay any self-employment tax, so include this in your calculations.

Step Two: Limit Your Needs To 50% Of Your After-Tax Income

Now go back to your budget. How much do you spend on “needs” each month? Things like groceries, housing, utilities, your Pension, Medical Insurance, car loan payments, and Car Insurance? According to Warren and Tyagi, and their 50/30/20 rule, the amount that you spend on these things; should total no more than 50% of your after-tax pay. 

Of course, now you must differentiate between which expenses are “needs” and which are “wants.” Basically, any payment that you cannot make with only minor inconveniences such as your Netflix bill or back-to-school clothing, is a want. Any payment that would severely impact your quality of life, such as electricity and prescription medicines, is a need.

If you can’t do without making a payment (such as a minimum payment on a credit card), it can be considered a “need,” according to the Warren and Tyagi. Why? Because your credit score could be negatively impacted if you don’t pay the minimum. By the same token, if the minimum payment required is $25 and you regularly pay $100 a month to keep a manageable balance, that additional $75 isn’t a “need”. 

 Step Three: Limit Your “Wants” To 30%

This sounds great at first glance, but can you put 30% of your money toward your “wants”? Hello, beautiful shoes, trip to Bali, salon haircuts, and Italian restaurants, etc. Not so fast! Remember how strict the definition of a “need” is? Your “wants” don’t include extravagances. They include the basic niceties of life that you enjoy, like that unlimited mobile phone plan, your home’s internet bill, and cosmetic (not mechanical) repairs to your car.

You might spend more on “wants” than you think. A threadbare minimum of warm clothing is a need. Anything beyond that, such as shopping for clothes at the mall rather than at a discount outlet, qualifies as a want. Yes, the rules are tricky, but if you think about it, they make sense. 

Step Four: Spend 20% On Savings And Debt Repayments

Now about the extra $75 you pay on that credit card each month. That’s neither a want nor a need. It’s the “20” in the 50/30/20 rule. It’s in a class all its own. You should spend at least 20% of your after-tax income repaying debts and saving money in your emergency fund and your retirement accounts. If you carry a credit card balance, the minimum payment is a “need” and it counts toward the 50%. Anything extra is an additional debt repayment, which goes toward this 20% category. If you have a mortgage or a car loan, the minimum payment is a “need” and any extra payments count toward “savings and debt repayment.”

An Example Of The 50/30/20 Plan 

Let’s say your total take-home pay each month is $3,500. Using the 50/30/20 rule, you can spend no more than $1,750 on your needs per month. You probably can’t afford a $1,500-a-month rent or mortgage payment, at least not unless your utilities, car payment, minimum credit card payments, Insurance premiums, and other necessities of life don’t exceed $250 a month!

If you already own your home or you’re locked into a rental lease, you’re pretty much stuck with that $1,500 payment. Consider relocating when your lease expires to make your budget more manageable or take a look at your other “needs” to see if there’s a way that you can reduce any of them. Maybe shop for more affordable Insurance or transfer the balance on that credit card to one with a lower interest rate so your minimum payment drops a bit? Your Independent Financial Adviser can help with that. Your goal is to be able to fit all these expenses into 50% of your take-home pay after-tax income.

You can spend $1,050 a month on your “wants” based on that $3,500 you’re bringing home each month. You might consider doing without a few things and shifting some of this money to your “needs” column if you’re coming up short there – not necessarily indefinitely but until you can get your needs down to a more manageable level. Remember, you still need 20% left over so you can save and pay off your debts according to the 50/30/20 plan. 

Now you have $700 left: that last 20%. You know what to do with it. Reduce debt, save for an emergency, and most importantly plan for your future by investing realistic amounts into your Pension!
