Is the 50/30/20 rule realistic? ›

For many people, the 50/30/20 rule works extremely well—it provides significant room in your budget for discretionary spending while setting aside income to pay down debt and save. But the exact breakdown between “needs,” “wants” and savings may not be ideal for everyone.

In his free webinar last week, Market Briefs CEO Jaspreet Singh alerted me to a variation: the popular 75-15-10 rule. Singh called it leading your money. This iteration calls for you to put 75% of after-tax income to daily expenses, 15% to investing and 10% to savings.

The online 50-30-20 calculator divides your monthly income into necessities, wants and savings. A classic rule of thumb is to split your monthly salary as follows: 50% goes into necessities (essential expenses such as rent and bills) 30% goes towards wants (such as food, activities, subscriptions and petrol)

It may not work for everyone. Depending on your income and expenses, the 50/30/20 rule may not be realistic for your individual financial situation. You may need to allocate a higher percentage to necessities or a lower percentage to wants in order to make ends meet. It doesn't account for irregular expenses.

Drawbacks of the 50/30/20 rule: Lacks detail. May not help individuals isolate specific areas of overspending. Doesn't fit everyone's needs, particularly those with aggressive savings or debt-repayment goals.

Calculating your target budget

If you make $3000 a month after taxes, then 50% ($1500) would go toward needs, the next 30% ($900) goes toward your wants or discretionary spending, and the remaining 20% ($600) goes toward your savings.

Applying the 50/30/20 rule would give them a monthly budget of: 50% for mandatory expenses = $2,500. 20% to savings and debt repayment = $1,000. 30% for wants and discretionary spending = $1,500.

Unverzagt says, start with a manageable amount, such as $10 per week or paycheck. Setting aside $10 each week adds up to $520 a year. That's a solid amount for a starter emergency fund. Putting savings into a high-yield savings account is one way to leverage compound interest and further grow your savings.

The value 72 is a convenient choice of numerator, since it has many small divisors: 1, 2, 3, 4, 6, 8, 9, and 12. It provides a good approximation for annual compounding, and for compounding at typical rates (from 6% to 10%); the approximations are less accurate at higher interest rates.

What is the cash Rule of 72? ›

It's an easy way to calculate just how long it's going to take for your money to double. Just take the number 72 and divide it by the interest rate you hope to earn. That number gives you the approximate number of years it will take for your investment to double.

The 70-20-10 budget formula divides your after-tax income into three buckets: 70% for living expenses, 20% for savings and debt, and 10% for additional savings and donations. By allocating your available income into these three distinct categories, you can better manage your money on a daily basis.

50% of your net income should go towards living expenses and essentials (Needs), 20% of your net income should go towards debt reduction and savings (Debt Reduction and Savings), and 30% of your net income should go towards discretionary spending (Wants).

The 50/30/20 budget rule was popularized by Sen. Elizabeth Warren—then a Harvard Law professor—and her daughter, Amelia Warren Tyagi, in their 2006 book “All Your Worth: The Ultimate Lifetime Money Plan.” They called it a “good rule of thumb” for getting your budget in order.

Important reminder: The 50/30/20 budget rule only considers your take-home pay for the month, so anything automatically deducted from your paycheck — like your work health insurance premium or 401k retirement contribution — doesn't count in the equation.

The 50/30/20 rule can be a good budgeting method for some, but it may not work for your unique monthly expenses. Depending on your income and where you live, earmarking 50% of your income for your needs may not be enough.

Yes, the 50/30/20 rule can be used to save for long-term goals. Allocate a portion of the 20% to savings specifically for your long-term goals, such as a down payment on a house, education funds, or investments. The rule is intentionally meant to bring focus to savings.

The 20% rule is a good general guide, but it isn't the right fit for everyone. Some people can save above that rate, while others merely struggle to make ends meet. “Some people pay their rent and they have nothing left.

The 30% Rule Is Outdated

To start, averages, by definition, do not take into account the huge variations in what individuals do. Second, the financial obligations of today are vastly different than they were when the 30% rule was created.
