## Prompt Examples

**Prompt:** 
```
If I start with $10,000 and add $500 every month at 6%, when will I hit $75k?
```

```
**Goal Check: Target of $75,000**

Based on your inputs:
*   Initial Investment: $10,000

Your target balance of $75,000 will be reached in **Month 42** (approximately 3 years and 6 months).

## Capabilities

### Generate Detailed Monthly Schedules
It creates a complete, month-by-month breakdown of your investment's growth over the specified period.

### Calculate Total Investment Summaries
You get high-level financial totals, including the total interest earned and the final balance after all contributions are factored in.

### Determine Target Milestone Dates
The MCP calculates the exact month required to reach a predefined monetary goal or target balance.

## Use Cases

### Saving for a House Down Payment
A user needs to know if saving $500 monthly is enough to hit a $100,000 down payment goal in five years. They ask their agent to use the `find_target_balance_month` tool, which confirms they're slightly short and suggests increasing contributions.

### Understanding Retirement Growth
A user wants a full picture of how an initial $10k deposit grows with annual additions over 30 years. They use the `generate_monthly_table` to see exactly where their money comes from month by month, confirming compounding's power.

### Comparing Investment Strategies
A planner needs to compare two clients: one with 5% interest and one with 7%. They run both through the MCP using `get_compounding_summary` to give their client a clear, quantitative comparison of total returns.

### Analyzing Emergency Fund Growth
Someone wants to know if they can build up a $25k emergency fund in four years while only contributing $300/month. They use the MCP's tools and find out exactly when that milestone will be hit.

## Benefits

- Stop guessing when you’ll hit your savings goal. Use the `find_target_balance_month` tool to calculate the exact month needed to reach any monetary target.
- Get crystal-clear visibility into your money. The `generate_monthly_table` provides a comprehensive, step-by-step view of every balance increase and interest accrual.
- Cut through the noise with instant summaries. The `get_compounding_summary` gives you total figures—like overall interest earned—without forcing you to look at 100 lines of data.
- Model 'what if' scenarios rapidly. Quickly adjust inputs (rate, contribution) and immediately see how it changes your projected growth curve.
- Increase financial confidence by grounding assumptions in concrete calculations. You move from gut feelings to provable numbers.

## How It Works

The bottom line is that you input the financial parameters, and it outputs precise growth timelines and totals without any manual calculation.

1. Provide your agent with the core variables: the initial deposit amount, the recurring monthly contribution, and the annual interest rate.
2. Tell the MCP what you want to calculate—for example, 'Show me the schedule for 24 months' or 'When will I hit $50,000?'.
3. The system returns a detailed report, either an itemized monthly table or a clear summary of your final balance and total interest earned.
