With instant loan approvals and zero-down-payment offers everywhere, buying on EMI (Equated Monthly Installment) has become incredibly easy. From smartphones and gadgets to cars and even homes, almost everything can now be purchased in small monthly installments. At first glance, EMIs feel light on the pocket and convenient—but without proper planning, this comfort can quietly turn into a long-term financial burden.

To help individuals make smarter borrowing decisions, financial experts often recommend a simple but effective guideline known as the ‘2-6-10 rule’. This rule acts as a reality check before opting for any EMI and helps you stay in control of your finances rather than letting debt take over.

Why EMIs Can Be Risky Without Planning

The biggest problem with EMIs is psychological. A large purchase feels affordable when broken into small monthly payments. Over time, people take multiple EMIs together—mobile, laptop, personal loan, credit card—and suddenly a significant portion of their income goes into repayments.

If income reduces or expenses increase, managing these EMIs becomes stressful. That’s where the 2-6-10 rule helps—it sets clear limits before you borrow.

What Is the 2-6-10 Rule?

The 2-6-10 rule is a straightforward formula to decide whether buying something on EMI is financially sensible or not. Each number represents an important borrowing limit.

Let’s understand it step by step.

‘2’ Rule: Product Price Should Not Exceed Half Your Monthly Salary

The first rule says that the total price of the item should not be more than 50% of your monthly salary.

Example:
If your monthly salary is ₹50,000, you should avoid buying a product worth more than ₹25,000 on EMI.

This rule is especially important for fast-depreciating items like smartphones, gadgets, and electronics. Expensive phones lose value quickly—often dropping to half their price within a year—while you may still be paying EMIs for them. Paying a high EMI for something that rapidly loses value is rarely a smart financial move.

‘6’ Rule: EMI Tenure Should Not Be More Than 6 Months

The second rule focuses on the duration of the EMI. According to this guideline, your EMI tenure should ideally be limited to six months.

Many people opt for 18-month or 24-month EMIs to reduce monthly payments. However, longer tenures mean:

• Higher total interest outgo




• Longer time stuck in debt




• Reduced flexibility for future expenses

Shorter tenures may feel slightly heavier on a monthly basis, but they help you become debt-free faster and reduce overall interest payments.

‘10’ Rule: EMI Should Not Exceed 10% of Your Monthly Income

The third and most crucial rule is about affordability. Your total EMI should not exceed 10% of your monthly income.

Example:
If your in-hand salary is ₹40,000, your EMI should ideally stay within ₹4,000 per month.

This ensures that your essential expenses—rent, groceries, utilities, savings, and emergencies—are not affected. When EMIs cross this limit, household budgets start getting disturbed, and savings often take the first hit.

Why Financial Experts Strongly Support the 2-6-10 Rule

Experts warn that easy loans can slowly increase financial pressure without being noticed. Once EMIs start piling up, people often rely on more credit to manage expenses, creating a debt cycle.

By following the 2-6-10 rule, you:

• Avoid overspending on depreciating assets




• Keep EMIs short and manageable




• Protect monthly savings and emergency funds




• Maintain financial discipline

Who Should Follow This Rule Strictly?

• Young professionals in the early stage of their career




• People with unstable or variable income




• First-time borrowers




• Anyone already paying multiple EMIs

Even high-income earners benefit from this rule, as it prevents lifestyle inflation and unnecessary financial stress.

Final Takeaway: Smart Borrowing Is Better Than Easy Borrowing

EMIs are not bad—but unplanned EMIs are. Before saying yes to any loan offer, pause and evaluate it through the 2-6-10 rule. A few minutes of calculation can save you years of financial pressure.

Easy loans may look attractive today, but financial freedom comes from discipline, planning, and controlled borrowing. Follow the 2-6-10 rule, and let EMIs work for you—not against you.
