What problem does it solve?

This Skill eliminates the tedious manual work of building what-if budget scenarios in Excel, allowing finance teams to model trim options, growth levers, and combined impacts without starting from scratch.

Core Features & Use Cases

  • Trim Scenarios: Model headcount reductions, revenue shocks, and cost rebalancing to hit cash targets.
  • Growth Scenarios: Simulate new fund raises and expansion hires with live formulas that update automatically.
  • Stacked Analysis: Combine multiple levers (e.g., fund raise plus hires) to see net P&L and cash impact.
  • Use Case: A CFO asks what would happen if they raise a $500M fund and hire 5 FTEs, and this Skill builds the scenario columns, cash-impact summary, and recommended option directly in the existing budget workbook.

Quick Start

Use the carta-budget-scenarios skill to model three trim options on your open Excel budget workbook and show the cash-impact summary for each.

FAQPage Schema
How do I build what-if budget scenarios in Excel for headcount reductions and revenue shocks?

This Skill constructs what-if scenario columns in your Excel budget workbook to model trim options like headcount reductions and revenue shocks, outputting live formulas that update automatically as inputs change.

What is the best way to model combined growth levers like a new fund raise and expansion hires in a budget workbook?

Stacked analysis combines multiple growth levers like new fund raises and expansion hires directly in your Excel budget workbook, generating live formula outputs that reveal the net P&L and cash impact of the combined scenarios.

Can I use Excel add-ins to automate cash-impact summaries for different trim options?

Yes, you can use an Excel add-in or local file runtime to generate cash-impact summaries for each trim option, building scenario columns and a recommended option directly within your existing budget workbook.

Do I need Carta MCP connectivity to run budget scenario modeling in Excel?

Yes, Carta MCP connectivity is required along with an Excel add-in or local file runtime to process your budget workbook and apply the necessary tab formatting references for scenario generation.

What are the limitations of using Excel for what-if financial modeling and cost rebalancing?

A limitation is the dependency on having an open Excel budget workbook, Excel add-in or local file runtime, and Carta MCP connectivity; it requires an existing workbook and cannot build scenarios from scratch on a blank spreadsheet.
