## Description

The Credit Card Payoff Engine provides precise simulations of debt repayment trajectories. When you're staring at high-interest credit card balances, the math can feel overwhelming. This MCP takes the guesswork out of debt management by applying precise daily compounding logic to your numbers. Instead of guessing how much progress you're making, you can ask your agent to build a month-by-month amortization table that shows exactly where every dollar goes. It handles the heavy lifting of calculating interest based on your specific APR, so you can see the real cost of your debt. You can use it to see how a small extra payment each month changes your finish date or to figure out the exact amount you need to pay to be clear by a specific year. It's a core part of the Vinkius catalog for anyone who wants to move from just 'paying off my cards' to having a concrete, mathematically sound plan. You get a clear picture of your debt's lifecycle without having to manually update a spreadsheet every time you make a payment.

## Prompt Examples

**Prompt:** 
```
I have a $5,000 balance at 19.99% APR. If I pay $200 every month, how long will it take to pay off and how much interest will I pay?
```

**Response:** 
```
Based on a $5,000 balance at 19.99% APR with a $200 monthly payment:

* **Time to Pay Off:** 34 months
* **Total Interest Paid:** $1,654.22
* **Status:** You'll be debt-free in just under 3 years.
```

**Prompt:** 
```
Compare paying $150 monthly vs adding an extra $50 monthly on a $3,000 debt at 24% APR.
```

**Response:** 
```
Here is how adding an extra $50 changes your trajectory for a $3,000 balance at 24% APR:

* **Option 1 ($150/mo):** Standard payoff.
* **Option 2 ($200/mo):** Saves you **$285.40** in total interest.
* **Time Saved:** You will finish your repayment **12 months sooner** by adding that extra $50.
```

**Prompt:** 
```
How much do I need to pay monthly to clear a $10,000 balance at 15% APR in exactly 24 months?
```

**Response:** 
```
To reach your goal of being debt-free in 24 months for a $10,000 balance at 15% APR:

* **Required Monthly Payment:** $484.87
* **Total Interest Paid:** $1,636.88
* **Note:** This is the minimum amount you need to commit to each month to hit your exact deadline.
```
