1. What is the Credit Limit Formula?

The HDFC credit card limit formula estimates maximum credit card limit based on income, expenses, debt-to-income ratio, and interest rate. It helps determine a reasonable credit limit that aligns with your financial capacity.

2. How Does the Calculator Work?

The calculator uses the following equation:

\[ CL_{max} = (I - E) \times F / R \]

Where:

\( I \) — Monthly income (INR)
\( E \) — Monthly expenses (INR)
\( F \) — Debt-to-income ratio factor (typically 0.3-0.4)
\( R \) — Monthly interest rate (APR / 12, as decimal)
\( CL_{max} \) — Maximum credit limit (INR)

Explanation: The formula calculates how much credit you can service based on your disposable income (income minus expenses), applying a conservative factor to account for debt obligations, and dividing by the monthly interest rate.

3. Importance of Credit Limit Calculation

Details: Understanding your potential credit limit helps in financial planning, maintaining good credit utilization ratios, and avoiding over-leveraging.

4. Using the Calculator

Tips: Enter your net monthly income, all monthly expenses, select a debt-to-income factor (typically 0.35), and your card's APR. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why is the debt-to-income factor important?
A: It accounts for your existing debt obligations and ensures the calculated limit is sustainable, typically ranging between 30-40% of disposable income.

Q2: What APR should I use for HDFC cards?
A: Standard HDFC cards typically have APRs between 24-42%. Check your card's terms or use 36% as a default.

Q3: Does this guarantee my actual credit limit?
A: No, this is an estimate. HDFC considers additional factors like credit score, employment history, and existing relationships.

Q4: How can I increase my credit limit?
A: Maintain good payment history, increase your income, reduce debts, and request limit increases after demonstrating responsible usage.

Q5: What's a good credit utilization ratio?
A: Ideally below 30% of your total limit across all cards to maintain a healthy credit score.
