† Kotak Royale Signature: Royale Signature points redeem at the ₹0.25 catalogue rate — Kotak's own reward table prices the Royale grid at "25 paise per point" — with no airline or hotel transfer partner anywhere in the programme. So 4 points per ₹150 on travel is 0.67% back and that is the ceiling, not a starting position.

Neither issuer publishes an income floor for these two. Kotak Air+ Prime is open to a direct application; Kotak Royale Signature is closed to new applications, and only grandfathered holders still have it. How people actually get each one 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.
