Side by Side

Rewards Compared

On a spend of Rs 10,000, the AU CS Credit Cardⓘ earns Rs 50 back at the base rate of 0.5%. It significantly boosts returns in dining and travel categories to Rs 200 per Rs 10,000 spent, which is four times its base rate. Utilities and insurance spend yield a modest Rs 25 back per Rs 10,000, half the base rate. This makes the AU CS card strong for users focusing on dining and travel expenses.

The IDFC First Wealth Credit Cardⓘ provides Rs 38 per Rs 10,000 spent at its base rate of 0.375%. Its category-specific return on utilities is Rs 12 per Rs 10,000, lower than the AU CS card’s utilities rate. The IDFC card does not offer elevated rewards in dining or travel, making it less attractive for those categories. However, the card’s value lies in its other benefits rather than category rewards.

Fees Compared

Both cards have no joining fee and no annual fee, making them very affordable to hold. Neither card specifies any fee waiver thresholds on spend, so there is no need to meet a minimum spend to retain the fee waiver. This makes the cost of ownership straightforward and risk-free for both.

The key charge difference arises in forex markup. The AU CS card charges 1.99% on foreign currency spends, amounting to Rs 1,990 on Rs 1,00,000 abroad. The IDFC First Wealth card is more competitive with a 1.5% forex markup, costing Rs 1,500 on the same spend. This lower forex cost favors frequent international travellers.

Which One Should You Pick

If you are a spender who values higher rewards on dining and travel and wants the most domestic lounge access, the AU CS Credit Cardⓘ is your best bet. It is especially suitable for those who frequently dine out or travel domestically and want a no-fee card with solid rewards. However, if you rarely spend on utilities and insurance but prioritize rewards on dining and travel, AU CS offers more.

The IDFC First Wealth Credit Cardⓘ suits a different profile: one who values international lounge access, lower forex markup, and additional lifestyle perks such as golf access. Its rewards on everyday spending categories are lower, so it is less ideal if maximizing reward returns is your goal. But for global travellers and those who want a lifestyle card without annual fees, it is a strong contender.

In conclusion, pick the AU CS card for better rewards and domestic lounge benefits. Opt for the IDFC First Wealth card if international lounge access and forex savings are priorities. Both are lifetime free, so choose based on your spending and travel habits. Avoid the AU CS card if you need international lounges or lower forex fees. Skip the IDFC card if you want higher category rewards and more domestic lounge visits.

What to Check Before You Apply

• Confirm if the dining and travel category rewards on the AU CS card have any spending caps or restrictions.
• Check the value and expiry rules for points redemption on both cards since neither mentions redemption rates.
• Understand the monthly spend gate of Rs 20,000 on the IDFC First Wealth card for lounge access to avoid surprises.
• Verify which airports and lounge networks are covered by the domestic and international lounge access for each card.
