# Retirement Withdrawal Calculator MCP for AI Agents AI Agent Connect

> Retirement Withdrawal Calculator estimates your retirement sustainability using Monte Carlo simulations. It calculates the probability of your portfolio surviving your planned horizon based on different withdrawal rates and asset mixes. It replaces guesswork with data-backed probabilities for your long-term financial plan.

## Description

Planning for retirement usually feels like a guessing game because market returns are never a straight line. Most people rely on a single percentage to figure out how much they can spend, but that doesn't account for a market crash in year two or a bull run in year ten. This Connector changes that by running a thousand different "what if" scenarios to see how your money actually holds up over time. You can see how a 3.5% withdrawal rate compares to a 4.5% rate and how different stock and bond mixes impact your safety net. It helps you move past static spreadsheets and into hard probabilities regarding your financial endurance. You can find this in the Vinkius catalog alongside other high-powered finance tools, making it easy to build a complete planning suite. Instead of staring at a single average, you get a dynamic look at the best and worst-case outcomes for your specific situation.

## Tools

### evaluate_portfolio_risk_profile
See the expected annual returns and volatility for your specific asset mix. This helps you understand the risk of your chosen investments.

### get_scenario_extremes
Identify the highest cumulative amount of money successfully withdrawn in a single scenario. Use this to see your best-case spending potential.

### simulate_withdrawal_probabilities
Simulate the probability of portfolio survival for different withdrawal rates like 3.5% or 4.5%. This gives you a clear success percentage.

## Prompt Examples

**Prompt:** 
```
I have $2 million and want to take out 4% a year for 30 years. What are my chances of not running out?
```

**Response:** 
```
Based on 1,000 Monte Carlo simulations, your probability of your portfolio surviving the 30-year horizon at a 4% withdrawal rate is approximately **94%**.

Here is a breakdown of the results:
* **Success Probability:** 94%
* **Best-Case Total Withdrawal:** $3,850,000
* **Worst-Case Total Withdrawal:** $1,200,000
```

**Prompt:** 
```
What happens if I go for a 5% withdrawal rate instead?
```

**Response:** 
```
At a 5% withdrawal rate, the survival probability drops to about **72%**.

This suggests that 5% might be pushing the limits of your current portfolio's endurance. You might want to consider a lower rate or a more aggressive asset mix to increase your success odds.
```

**Prompt:** 
```
Show me the risk for a portfolio that's 80% stocks and 20% bonds.
```

**Response:** 
```
For an 80% equity and 20% fixed income mix, here is the expected profile:

* **Expected Annual Return:** 7.5%
* **Annualized Volatility:** 12.4%

This mix offers a balance between growth and stability, though the 12.4% volatility means you should expect some significant year-to-year swings.
```

## Capabilities

### Run Monte Carlo simulations
Calculate the survival probability of your portfolio across a thousand different market paths.

### Identify best-case scenarios
Find the highest cumulative withdrawal totals possible for your target spending rate.

### Analyze portfolio volatility
Get a breakdown of the expected annual returns and risk for any asset mix.

## Use Cases

### Checking if a 4.5% withdrawal rate is too aggressive
A retiree asks their agent to check if a 4.5% withdrawal rate is sustainable for a 30-year plan. The agent uses simulate_withdrawal_probabilities to find the success rate.

### Comparing different stock and bond mixes
A financial planner needs to show a client the difference between a 60/40 and an 80/20 portfolio. The agent uses evaluate_portfolio_risk_profile to show the volatility for both.

### Finding the best-case spending scenario
An investor wants to know the maximum amount they could realistically take out in a lucky market. The agent uses get_scenario_extremes to find those totals.

### Stress testing a low-balance portfolio
A user with a smaller nest egg wants to see how much they can safely spend. The agent runs simulations to find a withdrawal rate with a 90% survival probability.

## Benefits

- Stop guessing about safe withdrawal rates by using simulate_withdrawal_probabilities to see real survival percentages.
- Understand your risk clearly with evaluate_portfolio_risk_profile, which breaks down the volatility of your stock and bond mix.
- See the ceiling of your retirement spending with get_scenario_extremes to identify best-case total withdrawals.
- Move from static planning to dynamic modeling by running 1,000 scenarios for every plan you consider.
- Make confident decisions on asset allocation by seeing how different equity mixes impact your long-term survival.

## How It Works

The bottom line is you get a data-backed probability of your portfolio lasting your entire retirement.

1. Input your current portfolio balance and your target annual withdrawal rate.
2. Define your retirement horizon and your preferred asset mix, such as a 60/40 stock and bond split.
3. Receive a survival probability percentage and a summary of the best and worst-case outcomes.

## Frequently Asked Questions

**What is a Monte Carlo simulation for retirement?**
It is a mathematical technique that runs thousands of different market scenarios to see how your retirement spending holds up. It helps you see the range of possible outcomes instead of just one average guess.

**How does the Retirement Withdrawal Calculator help me decide on a spending rate?**
It gives you a survival percentage for different rates. For example, you can see exactly how much your success probability drops if you move from a 4% withdrawal to a 5% withdrawal.

**Can I see the best-case scenario for my retirement spending?**
Yes, the tool identifies the highest cumulative amount of money you could successfully withdraw in the most successful simulated scenarios, giving you a look at the 'ceiling' of your plan.

**How does this tool handle different stock and bond mixes?**
You can input any asset mix, and the tool will calculate the specific expected return and volatility for that portfolio. This helps you see how your specific investments affect your long-term safety.

**Is this better than using a simple retirement spreadsheet?**
Yes, because a spreadsheet usually only shows one path. This tool shows you 1,000 different paths, accounting for the fact that markets are volatile and unpredictable.

**How many scenarios does the Retirement Withdrawal Calculator run?**
It runs 1,000 Monte Carlo scenarios for every calculation. This provides a robust statistical sample to give you a much more reliable probability of your portfolio lasting.

**What is a Monte Carlo simulation?**
It is a mathematical technique that uses randomness to model the probability of different outcomes in a process that cannot easily be predicted due to the intervention of random variables, such as market returns.

**How does this tool calculate withdrawal sustainability?**
The engine simulates 1,000 different market paths based on your asset allocation. It then checks how many of those paths allow your portfolio to remain above zero until the end of your retirement horizon.

**Can I test different asset allocations?**
Yes, you can use `evaluate_portfolio_risk_profile` to see the risk of your mix and then run simulations with various equity and fixed income percentages.
