3 Statement Model
Complete, populate and fill out 3-statement financial model templates (Income Statement, Balance Sheet, Cash Flow Statement) . Use when asked to fill out model templates, complete existing model frameworks, populate financial models with data, complete a partially filled IS/BS/CF framework, or link integrated financial statements within an existing template structure.

What this skill tells the agent
3-Statement Financial Model Template Completion
Complete and populate integrated financial model templates with proper linkages between Income Statement, Balance Sheet, and Cash Flow Statement.
⚠️ CRITICAL PRINCIPLES — Read Before Populating Any Template
Environment — Office JS vs Python:
- If running inside Excel (Office Add-in / Office JS): Use Office JS directly. Write formulas via
range.formulas = [["=D14*(1+Assumptions!$B$5)"]]— neverrange.valuesfor derived cells. No separate recalc; Excel computes natively. Usecontext.workbook.worksheets.getItem(...)to navigate tabs. - If generating a standalone .xlsx file: Use Python/openpyxl. Write
ws["D15"] = "=D14*(1+Assumptions!$B$5)", then runrecalc.pybefore delivery. - Office JS merged cell pitfall: Do NOT call
.merge()then set.valueson the merged range — throwsInvalidArgumentbecause the range still reports its pre-merge dimensions. Instead write value to top-left cell alone, then merge + format the full range:ws.getRange("A1").values = [["INCOME STATEMENT"]]; const h = ws.getRange("A1:G1"); h.merge(); h.format.fill.color = "#1F4E79"; - All principles below apply identically in either environment.
Formulas over hardcodes (non-negotiable):
- Every projection cell, roll-forward, linkage, and subtotal MUST be an Excel formula — never a pre-computed value
- When using Python/openpyxl: write formula strings (
ws["D15"] = "=D14*(1+Assumptions!$B$5)"), NOT computed results (ws["D15"] = 12500) - The ONLY cells that should contain hardcoded numbers are: (1) historical actuals, (2) assumption drivers in the Assumptions tab
- If you find yourself computing a value in Python and writing the result to a cell — STOP. Write the formula instead.
- Why: the model must flex when scenarios toggle or assumptions change. Hardcodes break every downstream integrity check silently.
Verify step-by-step with the user:
- After mapping the template → show the user which tabs/sections you've identified and confirm before touching any cells
- After populating historicals → show the user the historical block and confirm values/periods match source data
- After building IS projections → run the subtotal checks, show the user the projected IS, confirm before moving to BS
- After building BS → show the user the balance check (Assets = L+E) for every period, confirm before moving to CF
- After building CF → show the user the cash tie-out (CF ending cash = BS cash), confirm before finalizing
- Do NOT populate the entire model end-to-end and present it complete — break at each statement, show the work, catch errors early
Formatting — Professional Blue/Grey Palette (Default unless template/user specifies otherwise)
Keep colors minimal. Use only blues and greys for cell fills. Do NOT introduce greens, yellows, oranges, or multiple accent colors — a clean model uses restraint.
| Element | Fill | Font |
|---|---|---|
| Section headers (IS / BS / CF titles) | Dark blue #1F4E79 | White bold |
| Column headers (FY2024A, FY2025E, etc.) | Light blue #D9E1F2 | Black bold |
| Input cells (historicals, assumption drivers) | Light grey #F2F2F2 or white | Blue #0000FF |
| Formula cells | White | Black |
| Cross-tab links | White | Green #008000 |
| Check rows / key totals | Medium blue #BDD7EE | Black bold |
That's 3 blues + 1 grey + white. If the template has its own color scheme, follow the template instead.
Font color signals what a cell is (input/formula/link). Fill color signals where you are (header/data/check).
Model Structure
Identifying Template Tab Organization
Templates vary in their tab naming conventions and organization. Before populating, review all tabs to understand the template's structure. Below are common tab names and their typical contents:
| Common Tab Names | Contents to Look For |
|---|---|
| IS, P&L, Income Statement | Income Statement |
| BS, Balance Sheet | Balance Sheet |
| CF, CFS, Cash Flow | Cash Flow Statement |
| WC, Working Capital | Working Capital Schedule |
| DA, D&A, Depreciation, PP&E | Depreciation & Amortization Schedule |
| Debt, Debt Schedule | Debt Schedule |
| NOL, Tax, DTA | Net Operating Loss Schedule |
| Assumptions, Inputs, Drivers | Driver assumptions and inputs |
| Checks, Audit, Validation | Error-checking dashboard |
Template Review Checklist
- Identify which tabs exist in the template (not all templates include every schedule)
- Note any template-specific tabs not listed above
- Understand tab dependencies (e.g., which schedules feed into the main statements)
- Locate input cells vs. formula cells on each tab
Understanding Template Structure
Before populating a template, familiarize yourself with its existing layout to ensure data is entered in the correct locations and formulas remain intact.
Identifying Row Structure
- Locate the model title at top of each tab
- Identify section headers and their visual separation
- Find the units row indicating $ millions, %, x, etc.
- Note column headers distinguishing Actuals vs. Estimates periods
- Confirm period labels (e.g., FY2024A, FY2025E)
- Identify input cells vs. formula cells (typically distinguished by font color)
Identifying Column Structure
- Confirm line item labels in leftmost column
- Verify historical years precede projection years
- Note the visual border separating historical from projected periods
- Check for consistent column order across all tabs
Working with Named Ranges Templates often use named ranges for key inputs and outputs. Before entering data:
- Review existing named ranges in the template (Formulas → Name Manager in Excel)
- Common named ranges include: Revenue growth rates, cost percentages, key outputs (Net Income, EBITDA, Total Debt, Cash), scenario selector cell
- Ensure inputs are entered in cells that feed into these named ranges
Projection Period
- Templates typically project 5 years forward from last historical year
- Verify historical (A) vs. projected (E) columns are clearly separated
- Confirm columns use fiscal year notation (e.g., FY2024A, FY2025E)
Margin Analysis
Note: The following margin analysis should only be performed if prompted by the user or if the template explicitly requires it. If no prompt is given, skip this section.
Calculate and display profitability margins on the Income Statement (IS) tab to track operational efficiency and enable peer comparison.
Core Margins to Include
| Margin | Formula | What It Measures |
|---|---|---|
| Gross Margin | Gross Profit / Revenue | Pricing power, production efficiency |
| EBITDA Margin | EBITDA / Revenue | Core operating profitability |
| EBIT Margin | EBIT / Revenue | Operating profitability after D&A |
| Net Income Margin | Net Income / Revenue | Bottom-line profitability |
Income Statement Layout with Margins
Display margin percentages directly below each profit line item:
- Gross Margin % below Gross Profit
- EBIT Margin % below EBIT
- EBITDA Margin % below EBITDA
- Net Income Margin % below Net Income
Credit Metrics
Note: The following Credit analysis should only be performed if prompted by the user or if the template explicitly requires it. If no prompt is given, skip this section.
Calculate and display credit/leverage metrics on the Balance Sheet (BS) tab to assess financial health, debt capacity, and covenant compliance.
Core Credit Metrics to Include
| Metric | Formula | What It Measures |
|---|---|---|
| Total Debt / EBITDA | Total Debt / LTM EBITDA | Leverage multiple |
| Net Debt / EBITDA | (Total Debt - Cash) / LTM EBITDA | Leverage net of cash |
| Interest Coverage | EBITDA / Interest Expense | Ability to service debt |
| Debt / Total Cap | Total Debt / (Total Debt + Equity) | Capital structure |
