## Description

Managing cash flow doesn't have to be a spreadsheet nightmare. This MCP acts as a financial projection engine, simulating what happens to your bank account balance every single day based on known spending and scheduled income. You can see exactly how long your current funds will last and pinpoint when negative balances might occur. The tool handles recurring burn rates and complex cash flow events automatically, giving you true visibility into your company's liquidity.

It goes beyond simple totals. By analyzing daily fluctuations, it determines your operational runway and pinpoints the exact periods where a low balance is expected, helping you plan for capital injections or cost cuts well in advance. If you need financial forecasting tools integrated with your AI workflow, checking out the entire Vinkius catalog means you're covered. This MCP gives your agent all the data it needs to predict cash shortages and identify recovery windows.

## Tools

### calculate_cash_runway
Calculates the exact number of days your company can operate based on current burn rates and cash reserves.

### project_daily_balance_ledger
Provides a complete, day-by-day breakdown of expected bank balances, flagging potential overdraft dates as it goes.

### identify_overdraft_recovery_windows
Analyzes specific periods of negative balance to estimate exactly when funds will be replenished and stability returns.

## Prompt Examples

**Prompt:** 
```
If I start with $50k, burn $1k daily, but get a major payment of $20k on day 45, how long can I survive?
```

**Response:** 
```
**Day-by-Day Burn Forecast**

| Day | Starting Balance | Daily Activity | Ending Balance |
| :---: | :---: | :---: | :---: |
| 1 | $50,000 | -$1,000 | $49,000 |
| ... | ... | ... | ... |
| 43 | $8,000 | -$1,000 | $7,000 |
| 44 | $7,000 | -$1,000 | $6,000 |
| **45** | $6,000 | **+$20,000 (Client Payment)** | **$26,000** |

*Conclusion: With the payment boost on Day 45, your new cash runway is now approximately 26 days.*
```

**Prompt:** 
```
Can you show me a balance ledger for $10k starting funds with regular spending and an extra $3k outflow on day 15?
```

**Response:** 
```
**Simulated Balance Ledger**

The daily burn is steady at $50. The simulation shows the balance dropping consistently until Day 14, where it stands at **$8,000**. On Day 15, the additional $3,000 outflow brings the balance down to **$7,000**.

This means your immediate safety buffer after that outflow is reduced by $3,000.
```

**Prompt:** 
```
I'm worried about a big shortfall. What happens if my burn rate increases suddenly?
```

**Response:** 
```
**Burn Rate Impact Analysis**

*Current Runway: 95 days.* 

If the daily operational expenditure (OpEx) increases by $200, your cash runway drops from 95 days to **78 days**. This change significantly impacts your ability to absorb unexpected costs.

## Capabilities

### Predicting Operational Runway
Determines precisely how many days of business activity remain before the company balance hits zero.

### Forecasting Daily Balances
Generates a complete, day-by-day ledger showing expected bank balances and flagging immediate overdraft risks.

### Analyzing Negative Balance Periods
Identifies specific time windows where the balance is negative and estimates when incoming funds will restore stability.

## Use Cases

### Modeling the Impact of Delayed Payments
A startup founder needs to know what happens if their largest client pays 30 days late. They prompt their agent, asking for a simulation using `project_daily_balance_ledger`. The agent immediately shows the exact date and day count when cash reserves drop below safety levels.

### Determining Funding Needs Before a Crunch
A CFO needs to present a clear liquidity picture to investors. They ask for a full runway calculation using `calculate_cash_runway`, which provides the hard number of days they must survive, guiding their pitch deck requirements.

### Planning for Budget Shortfalls
An Ops Manager notices spending spikes and asks to analyze the negative periods. They use `identify_overdraft_recovery_windows` to pinpoint the exact dates when a large incoming receivable will cover the deficit.

### Comparing Spending Scenarios
A founding team compares two spending plans—one with new marketing, one without. They run both scenarios through the simulator to see which plan maintains a safer cash runway over the next quarter.

## Benefits

- Avoid critical surprises. By using the `project_daily_balance_ledger`, you get a daily view of your bank account, eliminating the risk of unexpected overdrafts.
- Know your limits instantly. The `calculate_cash_runway` tool tells you exactly how many days of operations remain, giving you clear targets for fundraising or cost reduction.
- Plan for recovery instead of reacting to crisis. You can use `identify_overdraft_recovery_windows` to predict when negative periods end and funds stabilize.
- Stop using static spreadsheets. This MCP updates forecasts dynamically as your cash flows change, providing real-time financial visibility.
- Model 'what if' scenarios quickly. Ask your agent how a major expenditure or delayed payment affects your runway without manually adjusting formulas.

## How It Works

The bottom line is you get a clear, predictable timeline of your company's financial health, eliminating guesswork from the burn rate.

1. Input your starting capital, recurring daily burn rates, and all scheduled cash inflows or outflows (e.g., payroll dates, client payments).
2. The MCP simulates these transactions day by day, building a comprehensive ledger that tracks the resulting balance at the end of each 24-hour period.
3. Your agent analyzes this projected data to report key metrics: your full cash runway remaining, or specific days when an overdraft event is predicted.

## Frequently Asked Questions

**How does the Day-by-Day Burn Simulator calculate my remaining operational lifespan?**
The simulator calculates how many full 24-hour periods you can operate before the projected bank balance hits zero. It accounts for every known expense and income event to give you a precise number.

**I need help predicting if I'll go into overdraft based on my spending schedule.**
This MCP handles that. You feed it your expected cash flow, and it will pinpoint the exact dates when your balance is predicted to dip below zero, giving you time to adjust.

**Can I use Day-by-Day Burn Simulator for comparing different spending plans?**
Yes. You can run multiple scenarios through the simulator—say, one with hiring and one without—to compare which plan maintains a safer cash runway over time.

**What if my revenue is irregular? Can it handle that in the Day-by-Day Burn Simulator?**
Absolutely. It models scheduled payments, no matter how irregularly spaced they are. You just tell it the expected date and amount for each major inflow.

**Does the Day-by-Day Burn Simulator account for taxes or other large one-time outflows?**
Yes, you include those as scheduled cash outflows. The simulator treats them just like any other expense when calculating your balance on that specific day.
