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.
