If you want one card that just pays you back without any hoops, the choice in 2026 narrows to two: Axis Ace with its flat 2% cashback model, and HDFC Millennia with its 5% partner-stack model. Which actually earns you more depends entirely on whether your spending fits Millennia's partner list.
Axis Ace — the flat-rate workhorse

HDFC Millennia — the partner stack

Real-spend math — three personas
Persona A — Online-shopping heavy (₹15K/month online split across Amazon, Flipkart, Swiggy):
- Axis Ace: ₹15K × 2% = ₹300/month → ₹3,600/year. (Direct merchant spend bypasses the 5% Google Pay tier.)
- HDFC Millennia: ₹15K × 5% (capped at ₹1,000/month) = ₹1,000/month → ₹12,000/year.
- Millennia wins by ₹8,400/year.
Persona B — Offline / utility heavy (₹40K/month groceries, fuel, rent, utilities):
- Axis Ace: ₹40K × 2% = ₹800/month → ₹9,600/year (uncapped).
- HDFC Millennia: ₹40K × 1% = ₹400/month → ₹4,800/year.
- Ace wins by ₹4,800/year.
Persona C — Mixed (₹10K online + ₹20K offline = ₹30K/month):
- Axis Ace: ₹30K × 2% = ₹600/month → ₹7,200/year.
- HDFC Millennia: ₹10K × 5% + ₹20K × 1% = ₹500 + ₹200 = ₹700/month → ₹8,400/year.
- Millennia wins by ₹1,200/year.
The crossover happens at roughly ₹12K/month of partner-merchant spend — below that, Ace; above that, Millennia. Use our Credit Card Reward Calculator to plug your exact split.
Lounge access — Millennia's hidden value
Millennia includes 8 domestic + 4 international lounge visits per year. At ~₹600 per domestic visit and ~₹2,200 per international visit, that's ~₹13,600 of pure value if you fly. Ace has zero lounge access. For a flyer, Millennia's higher fee pays itself back through lounges alone.
Verdict
If your online spend on Amazon/Flipkart/Swiggy is ₹12K+/month — HDFC Millennia. If your spend is mostly offline or you want zero category tracking — Axis Ace. Many smart spenders carry both: Millennia for partner merchants, Ace for everything else.
