| ₹0.25/pt † | House value | ₹0.25/pt † |
| 12,500 RP on joining-fee payment (₹12,500 at the ₹1 travel value) + a 25%-off 5-star hotel voucher worth up to ₹5,000 on ₹1L spent in 60 days — once per customer | Welcome benefit | Brand offers worth ₹5,000+ on joining-fee payment (ET Prime ₹1,199, Lenskart Gold Max ₹800, MakeMyTrip up to ₹1,600, Mokobara 10%, ₹500 off a first app flight booking) + 5% cashback up to ₹1,000 on a first EMI |
| 129 of 793 | Lounge doors opened | 129 of 793 |
† IDFC FIRST Gaj: Gaj redeems the IDFC point at ₹1.00 on flight and hotel bookings in the app's Travel & Shop section — FOUR TIMES the ₹0.25 house value, and the top rung on IDFC's ladder alongside FIRST Private — but ₹0.25 on vouchers, products or "pay with points". earn.base is scaled UP to that ₹1.00 reality, so the rate below collapses to a quarter of itself the moment you redeem for anything but app travel; points can only cover 70% of a booking, and 1.5L a month / 3L a year of them.
† IDFC FIRST Diamond Reserve: Diamond Reserve is the IDFC card with NO app-travel redemption premium: its own Privileges document says "1 reward point = ₹0.25", full stop, where Mayura gets ₹0.50 and Ashva ₹0.40. Points never expire and redeem as cash against any online purchase rather than a catalogue, which makes them unusually liquid for IDFC — they are simply worth the house ₹0.25, not a paisa more, and there is no in-app travel rung to chase.
Neither issuer publishes an income floor for these two. IDFC FIRST Gaj is invite-only, with no public form; IDFC FIRST Diamond Reserve is open to a direct application. How people actually get IDFC FIRST Gaj is on its card page.

The ₹ face-off at ₹1L/₹3L/₹5L a month
Ranking-value face-off
Everyday spend at each card's base rate plus a realistic ~20% at its best accelerator (less for narrow or capped boosters) — milestones, fee waivers and the redemption haircut all at our house ₹/point. That's why the biggest headline rate doesn't automatically win. This is the ranking model, the one that orders the board; each card page prints the earn-rate-only net annual value instead, which reads lower for any card with an accelerator (both models, side by side). Tune it to your own spend in the calculator.
