Meet Sarah & Mike
Sarah and Mike live in Seattle with their two kids. Like most dual-income households, they had accumulated credit cards over the years without much thought: a basic cashback card from their bank, an old airline card they forgot to cancel, and a Target RedCard.
They assumed all rewards cards were "basically the same."
Their annual spending looked typical for a family of four:
| Category | Annual Spend |
|---|---|
| Groceries (Costco + Safeway) | $9,600 |
| Dining (family dinners, takeout) | $4,200 |
| Gas (two cars, commuting) | $3,000 |
| Travel (one family trip) | $2,400 |
| Everything else | $12,000 |
The "Before" Reality
Using their 1.5% cashback card for everything, Sarah and Mike earned approximately $468 per year in rewards.
Not bad, right? That's what they thought too.
The CardSavvy Discovery
After a friend mentioned CardSavvy, Sarah spent 10 minutes entering their spending into the optimizer. What she discovered surprised her—they were leaving money on the table in every major category.
| Category | Old Strategy | Optimized Strategy | Annual Difference |
|---|---|---|---|
| Groceries | 1.5% ($144) | 6% Blue Cash Preferred ($576) | +$432 |
| Dining | 1.5% ($63) | 4x Amex Gold at 2cpp ($336) | +$273 |
| Gas | 1.5% ($45) | 5% rotating category ($150) | +$105 |
| Travel | 1.5% ($36) | 3x CSP at 1.5cpp ($108) | +$72 |
New total annual rewards: $1,170
Improvement: $1,170 - $468 = $702 more per year
After accounting for annual fees ($95 Chase Sapphire Preferred + $95 Blue Cash Preferred = $190):
Net annual improvement: $512
The Real-World Impact
"That's basically a free night at a nice hotel every year, or three months of streaming services, just for using the right card at checkout. We didn't change how we spend—we just changed which card we pulled out."

Key Takeaways
- Net annual gain: $512

- Cards added: 2 (Amex Blue Cash Preferred, Chase Sapphire Preferred)
- Behavior change required: None—just card selection at checkout
The math was simple once CardSavvy laid it out. Sarah and Mike weren't earning bad rewards before—they just weren't earning the right rewards for their spending patterns.
These results are based on example spending patterns. Your actual savings will depend on your specific spending habits, current cards, and the cards you qualify for.
