💼 Financial Modeling in Excel – Step-by-Step Tutorial

1. Introduction to the Exercise

Understand the objectives of financial modeling:

• Forecast business performance
• Analyze profitability, liquidity, solvency
• Build an integrated model: P&L, Balance Sheet, Cash Flow

You’ll work with:

• Historical financial data (3–5 years)
• Forecast assumptions
• Dynamic Excel functions

---

2. Mapping the Financials

Create a mapping sheet to classify raw data into categories like:

• Revenue
• COGS
• Operating Expenses
• Assets
• Liabilities

Example:

=IF(A2="Sales","Revenue",IF(A2="Interest Income","Other Income",""))

Use this mapping to structure output statements.

---

3. Build the Output Profit & Loss (P&L) Sheet

Create a clean summary for P&L:

• Rows: Revenue, COGS, Gross Profit, OPEX, EBITDA, Net Profit
• Columns: Historical and forecast years

Link each line item to mapped categories using SUMIF, INDEX, or MATCH.

---

4. Populate Historical Financials in Output P&L

Pull values from raw input sheets:

• Use SUMIFS, INDEX-MATCH, or structured references from Power Query outputs.

Ensure accuracy by cross-verifying totals.

---

5. Calculate Percentage Variance and Add Conditional Formatting

Calculate YoY variance:

=(CurrentYear - PreviousYear)/PreviousYear

Add conditional formatting:

• Green for growth
• Red for decline

Improves visual storytelling in reports.

---

6. Build the Output Balance Sheet

Sections:

• Assets: Current (Cash, AR, Inventory), Non-current (PP&E)
• Liabilities: Current (AP), Long-term (Loans)
• Equity: Share Capital, Retained Earnings

Follow the accounting equation:

Assets = Liabilities + Equity

---

7. Use INDEX-MATCH-MATCH for Balance Sheet Lookup

For structured and scalable lookup:

=INDEX(Data!$B$2:$G$100, MATCH("Inventory", Data!$A$2:$A$100, 0), MATCH("2023", Data!$B$1:$G$1, 0))

This allows flexible, multi-year access.

---

8. Add Forecast Period Columns

Extend your model with forecast years (e.g., FY24E to FY26E).

Forecast revenue:

=LastYearRevenue*(1 + AssumedGrowthRate)

Apply same for cost and other variables using drivers.

---

9. Calculate Ratios Using OFFSET and MATCH

Use ratios to analyze trends and build assumptions:

• Gross Margin, OPEX %, Net Margin
• DSO, DPO, DIO, etc.

Example:

=OFFSET(P&L!C5,0,1)/OFFSET(P&L!C5,0,0)

MATCH dynamically selects year/period.

---

10. Build Flexible Models with CHOOSE and MATCH

For scenario-based models:

=CHOOSE(MATCH(Scenario, {"Base","Best","Worst"}, 0), BaseGrowth, BestGrowth, WorstGrowth)

Useful for executive decision-making.

---

11. Use VLOOKUP and COLUMNS for Dynamic Scenarios

Another way to automate scenario modeling:

=VLOOKUP("Revenue", ScenarioSheet!$A$2:$D$10, COLUMNS($A:A)+1, FALSE)

Each scenario (Base, Best, Worst) in separate columns.

---

12. Calculate Historical Working Capital Ratios

Key ratios:

• DSO = (Accounts Receivable / Revenue) * 365
• DPO = (Accounts Payable / COGS) * 365
• DIO = (Inventory / COGS) * 365
• Other Assets % = Other Assets / Revenue

Helps in building accurate cash flow and net working capital forecasts.

---

13. Forecast Working Capital Items

Use historical averages or policy targets to forecast:

• DSO, DPO, DIO
• Other Assets & Liabilities as % of Revenue

Apply to forecast Balance Sheet and cash flow needs.

---

14. Build a Fixed Asset Roll Forward

Track the PP&E movement:

Opening Balance
+ Additions
– Disposals
– Depreciation
= Closing Balance

Automate using rows and formulas across forecast years.

---

15. Build the Financial Liabilities Schedule

Track debt repayments and interest:

• Opening Balance
• Additions
• Principal Repayments
• Interest Expense

Create an amortization table using formulas:

=IF(Year<=MaturityYear, PreviousBalance – Repayment, 0)

---

16. Build the Equity Schedule

Track:

• Issued capital
• Retained earnings (link to Net Profit)
• Dividends

Formula:

=LastYearRetainedEarnings + NetProfit – Dividends

Ensure this flows into Balance Sheet and matches accounting identity.

---

17. Prepare the Cash Flow Statement

Break into sections:

• Operating: Net Profit + adjustments
• Investing: Capex, asset sales
• Financing: Loans, repayments, dividends

Start from Net Profit and adjust:

=Net Profit + Depreciation – Capex ± Working Capital Changes ± Financing

---

18. Calculate Final Cash Flows & Validate Model

Link ending cash from cash flow to Balance Sheet.

• Ensure:

Opening Cash + Net Cash Flow = Closing Cash

Use a balance check:

=IF(Assets = Liabilities + Equity, "Balanced", "Error")

---

✅ Final Output

You now have a:

• Fully integrated 3-statement model
• Scenario-based forecasting tool
• Financial ratio analyzer
• Decision-making dashboard
