Portal vs. Category Bonus: How to Decide
A decision framework for choosing between shopping portal cashback and a card's category multiplier — with examples.
Key Takeaways
- Convert your card multiplier to effective return before comparing to portal rates.
- Stacking both is usually possible and often the best outcome.
- Portal rates above 5% are generally worth the extra friction for any purchase.
The Core Question
Your card earns 5x points at a merchant. A cashback portal is offering 6%. Which is better?
The answer depends on one thing: your point valuation. Once you have that number, the comparison becomes arithmetic.
The Comparison Formula
Convert your card multiplier to an effective percentage:
Card Effective Return = Earn Rate × Point Value (cents) / 100Then compare directly to the portal rate.
Example: 5x points at 1.5 cents per point = 7.5% effective return. A 6% portal rate loses. But if your point value is 1.0 cent, 5x = 5% effective return — and the portal wins.
When the Portal Typically Wins
- Your card earns at a low multiplier (1x–2x) at the merchant
- The portal rate is high (8%+)
- You value points conservatively (at or near cash equivalent)
- You don't have category bonus eligibility at this merchant
When the Card Typically Wins
- Your card earns a high multiplier (5x+) at the category
- You have a high point valuation (1.5+ cents)
- The portal rate is modest (2–4%)
- You have a relevant merchant offer stacked on the card
Can You Stack Both?
Yes — and this is usually the best outcome. Using the portal doesn't prevent your card from earning its normal rate. The question of "portal vs. card" only arises when you're trying to decide whether to bother with the portal on a given purchase.
The real decision is: is the portal rate high enough to justify the extra step of clicking through and maintaining cookie tracking?
Quick Decision Rule
For most people, a simple rule works well:
- Portal rate ≥ 5%: Always use the portal (the extra step is worth it)
- Portal rate 2–4%: Use portal if your card earns 1–2x at this merchant; skip it if you have a 5x bonus card
- Portal rate < 2%: Usually not worth the friction unless you're making a very large purchase
