## Description

The Inflation-Adjusted Return Calculator helps you figure out what your money is actually worth after inflation eats a piece of it. Most people look at a bank statement and see a percentage gain, but that number doesn't tell the whole story if prices are also climbing. This Connector changes how you track your portfolio by stripping away the noise of inflation to show you what's actually happening to your wealth. You can ask your agent to do the heavy lifting of calculating real returns, so you don't have to pull out a calculator or hunt for CPI data every time you want to check your progress. It's built for people who need to know if their investments are actually keeping pace with the world. When you connect this to your workflow through the Vinkius catalog, your AI client becomes a sharp financial analyst. It handles the math behind purchasing power and currency erosion, letting you focus on high-level strategy instead of getting bogged down in the weeds of economic adjustments. You'll get clear answers on whether your money is growing or just staying stagnant in a changing economy. This tool provides a grounded perspective on your finances, ensuring that your long-term goals remain realistic regardless of how volatile the economy gets. It turns raw data into a clear narrative about your actual financial progress.

## Tools

### compute_absolute_inflationary_erosion
Calculates the exact amount of money lost to rising prices in currency units. This helps you see the real impact on your savings.

### calculate_purchasing_power_ratio
Shows you what percentage of your original buying power you still have left. It turns complex data into a simple ratio.

### get_real_return_percentage
Uses the Fisher equation to give you the true growth rate of an investment. It strips out inflation to show real profit.

## Prompt Examples

**Prompt:** 
```
I made 7% on my stocks this year, but inflation was 4%. What was my real return?
```

**Response:** 
```
Based on the Fisher equation, your real return is approximately **2.94%**. 

This means your purchasing power grew by about 3% after accounting for rising costs. Here is the breakdown:

* **Nominal Return:** 7.00%
* **Inflation Rate:** 4.00%
* **Real Return:** 2.94%

Your money is growing, but it's doing so at a much slower pace than the raw numbers suggest.
```

**Prompt:** 
```
If I have $50,000 and inflation was 5% over the last year, how much purchasing power did I lose?
```

**Response:** 
```
You lost approximately **$2,500** in purchasing power. 

Your preservation ratio is **0.95**, meaning your $50,000 now buys what $47,500 would have bought a year ago. 

| Metric | Value |
| :--- | :--- |
| Original Value | $50,000 |
| Purchasing Power Lost | $2,500 |
| Preservation Ratio | 0.95 |
```

**Prompt:** 
```
My portfolio grew by 10% nominal, but inflation was 6%. What's the absolute erosion?
```

**Response:** 
```
The absolute inflationary erosion on your investment is **6%** of the total value. 

If you invested $10,000, that is a loss of **$600** in purchasing power. While your balance went up, the actual value of those dollars decreased by $600 relative to the cost of goods.
```

## Capabilities

### Calculate real growth percentages
Determine your actual investment returns by stripping out the effects of inflation.

### Determine purchasing power retention
See what percentage of your original buying power remains after a period of price changes.

### Quantify currency value loss
Get the exact dollar amount lost to inflation over a specific timeframe.

### Apply the Fisher equation to returns
Use standard economic formulas to convert nominal gains into real wealth growth.

### Analyze investment performance over time

## Use Cases

### Retirement nest egg checking

### Stock market profit analysis
A trader wants to see if a 10% gain in a high-inflation year actually resulted in a profit. They use the tool to find the real return percentage.

### Real estate value tracking
A property owner wants to calculate how much purchasing power their home value has retained over a decade. They use the purchasing power ratio.

### Crypto asset comparison
A crypto holder wants to compare their portfolio's real return against the standard CPI. They use the tool to see the actual wealth preservation.
