## Prompt Examples

**Prompt:** 
```
I'm buying a $500 jacket. I can use a Pay in 4 plan with a $15 late fee, or my credit card with 24% APR if I carry the balance for 30 days, or pay cash with a 5% discount. Which is best?
```

**Response:** 
```
Here is the cost breakdown for your $500 purchase:

| Payment Method | Total Cost | Notes |
| :--- | :--- | :--- |
| **Cash** | **$475.00** | **Winner (5% discount)** |
| Credit Card | ~$510.00 | Based on 24% APR for 30 days |
| BNPL Plan | $515.00 | Includes $15 late fee risk |

Paying with **Cash** saves you the most money upfront.
```

**Prompt:** 
```
Calculate the impact of a $1,200 purchase on my 19% APR credit card if I don't pay it off for 60 days.
```

**Response:** 
```
If you carry a **$1,200 balance** at **19% APR** for **60 days**, the results are:

*   **Interest Accrued:** $38.63
*   **Total Repayment:** $1,238.63

Carrying this balance will cost you approximately $38.63 in additional interest charges.
```

**Prompt:** 
```
Compare a $1,000 item using a 'Pay in 30 days' plan with a $1,000 cash payment that offers a $50 rebate.
```

**Response:** 
```
Here is your comparison for the $1,000 item:

*   **Cash Payment:** $950.00 (Includes $50 rebate)
*   **Pay in 30 Days:** $1,000.00

**The Cash option is the winner**, saving you $50.00 total. Be aware that the BNPL plan carries a risk of late fees which would increase that $1,000.00 base cost.
