Managing debt can feel overwhelming, but the 20/10 rule can be a simple way to help keep your finances on track. This budgeting rule suggests that you shouldn’t spend more than 20% of your annual take-home income and 10% of your monthly take-home income on consumer debt payments. But how do you apply it effectively?

In this article, we’ll explain the 20/10 rule definition, its benefits and drawbacks, and give easy tips to use it in your financial routine. By learning this rule, you’ll be able to make better decisions about handling debt and spending wisely.

What is the 20/10 Rule?

You might hear someone say casually, “I only spend 20% of my income on debt.” While this may seem like a simple statement, it actually stems from the 20/10 rule.

This rule suggests that you should spend no more than 20% of your annual take-home income on consumer debt—this includes credit card bills, car loans, and student loans—and have a maximum of 10% of your budget allocated towards monthly payments. This approach ensures that your debt is manageable and does not become a heavy burden on your monthly finances.

How to use the 20/10 rule

Using the 20/10 rule involves simple calculations that anyone can perform—even if you struggle with financial planning. Start with your monthly after-tax income, which appears on your paycheck or bank statement. Multiply this number by 10% to find out the maximum amount you should allocate for debt payments each month.

For example, let’s say your monthly after-tax income is $5,000.

Monthly calculation

  • Monthly debt limit: $5,000 × 10% = $500
  • Result: Your debt payments should not exceed $500 per month.

Next, calculate your annual limit by multiplying your monthly after-tax income by 12 and then by 20%. This will give you the upper threshold for your total consumer debt.

Annual calculation:

  • Annual income: $5,000 × 12 = $60,000
  • Annual debt limit: $60,000 × 20% = $12,000
  • Result: Your annual debt should not exceed $12,000.

Pro tip: You can also use a 20/10 rule calculator, such as those available online or through smartphone apps like Mint or Personal Capital, to simplify your calculations. These tools can help you keep track of your debt and ensure you stay within the 20/10 rule limits.

Exceptions: When the 20/10 rule might not apply

While the 20/10 rule in finance is a useful guideline for managing debt, there are some situations where it may not be applicable or necessary.

  • Mortgages: As mortgages are typically long-term loans with low interest rates, they do not fall under the same category as consumer debt. However, it is still important to ensure that mortgage payments fit within your overall budget and do not exceed 28% of your monthly income.
  • Low-income individuals: For those with low incomes, it may not be feasible to limit debt payments to 10% of their income. In this case, alternative measures such as reducing expenses or increasing income may be more suitable for managing debt.
  • Emergency situations: In the event of an emergency, such as unexpected medical expenses or job loss, it may be necessary to temporarily exceed the 20/10 rule to cover necessary costs. However, it is important to create a plan for paying off any additional debt acquired during these situations as soon as possible.

Pros and cons of the 20/10 rule

The 20/10 rule is a popular guideline for managing debt, and it has its advantages and disadvantages.

Pros

  • It helps with debt management. The 20/10 Rule helps you keep your debt in check by setting limits based on your income. If your annual debt payments exceed 20% of your annual income, or your monthly debt payments exceed 10% of your monthly income, it means you’re taking on too much. In this case, the rule suggests holding off on taking on more debt until you’ve paid down what you already owe.
  • It promotes financial health. By adhering to this rule and limiting consumer debt, individuals can promote better financial health and improve their credit scores. A lower debt-to-income ratio often leads to more favorable lending terms and increased financial stability.
  • It supports goal setting. The 20/10 rule provides a clear target for reducing consumer debt, encouraging individuals to develop responsible financial habits. By focusing on reducing debt, you can set realistic financial goals and work towards achieving them in a structured manner.
  • It allows for some flexibility. While the rule suggests keeping annual consumer debt under 20%, it also allows for some flexibility in case of emergencies or unexpected expenses. This can prevent financial strain and provide a safety net in times of need.
  • It’s easy to implement. The 20/10 rule is simple and easy to implement. It doesn’t require complex calculations or budgeting, making it accessible to people of all financial backgrounds.

Cons

  • It’s not one-size-fits-all. The 20/10 rule excludes debts like mortgages or rent, focusing only on consumer debt like credit cards and personal loans. This limits its effectiveness for those with diverse debts, such as student loans and car payments. The rule’s strict percentages might also not fit everyone, especially those with variable incomes, like freelancers or seasonal workers.
  • It may not suit high-income earners. The 20/10 rule may not be suitable for high-income earners who have higher living expenses and larger debt obligations due to their lifestyle and career choices. For them, a higher threshold or different approach to managing debt may be more beneficial.
  • It overlooks saving priorities. While the 20/10 rule prioritizes paying off consumer debt, it does not emphasize the importance of saving for other financial goals, such as retirement or emergency funds. This could potentially limit long-term financial stability and security.

Comparing the 20/10 rule with the 70/20/10 rule

The 20/10 rule targets debt management, limiting consumer debt payments to 20% of your annual take-home income and 10% of your monthly take-home income. On the other hand, the 70/20/10 rule takes a wider view of budgeting, splitting your income into 70% for living expenses, 20% for savings and debt repayment, and 10% for personal expenses—this could include entertainment, dining out, or other discretionary spending.

While the 20/10 rule focuses mainly on keeping debt in check, the 70/20/10 rule promotes a more balanced approach to your overall finances and helps set financial goals.

Is the 20/10 rule right for you?

To decide whether the 20/10 rule is suitable for you, consider your financial situation, goals, and debt levels. If you’re looking for a straightforward way to manage debt and avoid excessive borrowing, this rule can be a valuable tool. However, if your financial situation includes significant student loans or other unique considerations, you may need to adapt the rule to fit your needs.

Ultimately, the key is to find a debt management strategy that suits you and your financial goals. If the 20/10 rule isn’t right, there are other methods like the snowball or avalanche to help you pay off debt in a way that fits your situation. Research and professional advice can help you find the best solution for managing your debt.
