† IDFC FIRST Gaj: Gaj redeems the IDFC point at ₹1.00 on flight and hotel bookings in the app's Travel & Shop section — DOUBLE the ₹0.50 house value and 2.5× Ashva's ₹0.40 — and ₹0.25 on vouchers, products or "pay with points". earn.base is scaled UP to that ₹1.00 reality; points can only cover 70% of a booking, and 1.5L a month / 3L a year of them.

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.
