Cash Back Structure Comparison
You need to focus on the structure because it determines how rewards accumulate. Each model applies a different earning formula.
- Flat Rate – Unlimited applies a fixed percentage to every purchase, with no category limits.
- Bonus Category – Customized offers a higher percentage in one selected spending category.

Earning Potential Scenarios
You need to test both models using realistic spending patterns. Your results depend on how and where you spend.
- General Spending Pattern – Broad spending favors the flat-rate model for steady rewards.
- High Category Spending – Concentrated spending in one category increases category-based rewards.
- Mixed Spending Behavior – Split spending depends on whether the bonus cap is reached.
- Quarterly Cap Impact – Once the bonus limit is exceeded, additional spending earns only the base rate, reducing the advantage.
- Preferred Rewards Boost – Higher loyalty tiers significantly increase total earnings, especially for higher spenders.
Preferred Rewards Program Impact
You need to understand how loyalty tiers increase your cash back rate. The higher your balance relationship, the higher your bonus.
- Tier Qualification – Based on combined balances in eligible Bank of America and Merrill accounts.
