IDFC FIRST Bank follows a dynamic pricing model for its credit products. This means the interest rate is not fixed and may vary across cardholders based on individual profiles and the type of credit card.
Dynamic Interest Range: The monthly interest rate typically ranges from 0.75% to 3.5%, which translates to an annualised rate of 9% to 42%. This range reflects variations based on the cardholder’s credit profile and the specific card variant.
Overdue Interest Rate: If the Minimum Amount Due is not paid by the due date, an overdue interest rate of 3.99% per month (47.88% per annum) is applied. This rate is calculated on the outstanding balance as per the billing cycle terms.
Determination Factors: The specific rate assigned to a customer is determined by internal bank parameters, including credit history, purchase patterns, and payment behaviour. These factors are assessed to define the applicable interest bracket.
IDFC FIRST Bank follows a dynamic interest rate model across its credit card portfolio. This means interest rates are not fixed by card variant and are instead assigned individually based on the cardholder’s credit profile.
For variants such as IDFC FIRST Select and IDFC FIRST Wealth, the assigned rate may fall within different points of the approved APR range depending on factors such as income stability, repayment history, and overall credit profile.
Entry-level or mass variants such as IDFC FIRST Millennia, Classic, SWYP, Power, and EA₹N follow the same framework, where the final rate is determined through individual risk assessment rather than the card category alone. The IDFC FIRST WOW! Credit Card, although secured, also operates under the same dynamic pricing structure.
The following points explain how interest rates are applied across different variants and what factors influence the final rate:
Variant-based structure: Interest rates are not predefined for specific card variants. All variants follow a common dynamic APR framework, where the applicable rate is assigned at the individual level.
Premium vs entry-level cards: Variants positioned as premium or entry-level do not carry fixed interest rate differences. The assigned APR depends on the cardholder’s financial and credit profile rather than the variant itself.
Secured card treatment: The IDFC FIRST WOW! Credit Card, despite being backed by a deposit, follows the same interest rate model as unsecured cards. The secured nature does not result in a separate or fixed APR structure.
Key influencing factors: The applicable interest rate is influenced by parameters such as CIBIL score, repayment behaviour, total credit exposure, utilisation levels, and overall relationship with the Bank. These factors are assessed as part of the internal risk evaluation process.
Rate review scope: In certain cases, interest rates may be reviewed based on long-term card usage and consistent repayment patterns, subject to the Bank’s internal policies and evaluation criteria.
Interest applicability condition: Interest applies only when the total amount due is not paid by the due date. This condition is defined as part of the official credit card terms.
Credit card interest is computed using a daily calculation method, where the outstanding balance is tracked across each day of the billing cycle. The final interest amount depends on how long a balance remains unpaid and how it changes over time due to transactions or payments.
The following points explain how this calculation typically works:
Daily balance method:
Interest is calculated on the outstanding amount for each day. Any payments, refunds, or new transactions adjust the balance, which then becomes the basis for the next day’s calculation.
Calculation approach:
The interest amount is derived using a standard formula that considers the outstanding balance, the applicable annual interest rate, and the number of days the balance remains unpaid.
Formula to calculate Interest Charged:
Interest Charged = (Outstanding Amount × Annual Interest Rate × Number of Days) ÷ 365
Transaction coverage:
Interest applies to different types of transactions, including purchases, cash advances, balance transfers, and billed EMIs. Each category may be included in the outstanding balance for interest computation.
Exclusions:
Interest is generally not applied to certain components such as fees, charges, or applicable taxes. These are treated separately as per the card’s billing structure.
Time-based impact:
The number of days for which a balance remains unpaid directly affects the total interest charged. A longer outstanding period results in a higher accumulated amount under the same rate.
The grace period refers to the time between the transaction date and the payment due date, during which interest may not be charged if the outstanding amount is cleared as per the billing terms.
Interest-free period: Cardholders can receive an interest-free period of around 45 to 48 days for purchases. This period depends on the billing cycle and the timing of the transaction within that cycle.
Interest-free cash withdrawals: A unique feature of IDFC FIRST Bank credit cards is interest-free cash withdrawals for around 45 to 48 days on select variants such as Wealth, Select, Millennia, and Classic. However, a cash advance fee of ₹199 + GST applies per transaction. This fee is billed to the cardholder in the next statement and remains subject to change at the sole discretion of IDFC FIRST Bank.
Loss of grace period: If the Total Amount Due is not cleared by the payment due date, the interest-free period is no longer applicable. In such cases, interest is charged from the date of the original transaction as per the billing terms.
Failure to pay at least the Minimum Amount Due (MAD) by the due date results in high-cost penalties.
Late Payment Fee: 15% of the unpaid Total Amount Due, subject to a minimum of ₹100 and a maximum of ₹1,250.
Reward Penalty: Effective January 18, 2026, if the cardholder fails to pay the Minimum Amount Due, all reward points earned in that specific billing cycle will be forfeited or reversed.
Apart from IDFC FIRST Bank credit card rate of interest, certain fees and charges may also form part of the overall cost structure of a credit card. The following charges are applied based on specific transactions or usage conditions:
| Fee Type | Charge Amount |

Forex Markup |
Up to 3.5% |
Overlimit Charges |
2.5% of overlimit amount (Subject to a minimum charge of ₹500) |

Disclaimer: Fees and charges may vary depending on the specific credit card variant and its applicable terms. The above-mentioned charges are subject to change at the issuer’s discretion.
Interest charges on credit cards depend on how the outstanding balance is managed across billing cycles. The following points outline common scenarios that may influence how interest is applied:
Full payment within due date: Paying the total amount due by the payment due date ensures that no interest is charged on purchases for that billing cycle, as per standard credit card terms.
Minimum due vs total due: Paying only the minimum amount due keeps the account active but results in the remaining balance being carried forward, on which interest is calculated.
Early or multiple payments: Making payments before the due date or in multiple parts during the billing cycle can reduce the outstanding balance used for daily interest calculation.
Cash advance usage: Cash withdrawals through a credit card are typically included in interest calculations from the transaction date, which may affect the overall interest amount.
Credit utilisation levels: Higher utilisation of the credit limit increases the outstanding balance, which may lead to a higher interest calculation if not cleared within the billing period.
Billing cycle awareness: Understanding the billing cycle and transaction dates helps in tracking how long a balance remains unpaid, which directly affects interest computation.
