Financial modelling is one of the most important skills in finance. It helps professionals forecast business performance, analyse investments, measure risk, prepare budgets, value companies and support better financial decisions. Traditionally, Excel has been the main tool for financial modelling. But today, Python has become equally important for automation, data analysis, risk modelling and scalable finance workflows.
This is why financial modelling using Python and Excel is a powerful skill combination for students, finance professionals and working executives who want to build practical, job-ready finance skills.
Excel helps learners understand model structure, formulas, assumptions and business logic. Python helps learners automate calculations, handle large datasets, perform statistical analysis and build repeatable financial models. Together, they create a strong foundation for modern financial modelling.
What Is Financial Modelling?
Financial modelling is the process of creating a structured model that represents a company, investment, project, portfolio or risk scenario. A financial model uses assumptions, formulas and data to estimate future outcomes and support decision-making.
Financial modelling is used for:
- Revenue forecasting
- Expense budgeting
- Business planning
- Valuation
- Credit analysis
- Risk modelling
- Portfolio analysis
- Scenario analysis
- Sensitivity analysis
- Financial reporting
- Investment decision-making
A good financial model should be accurate, flexible, transparent and easy to review. A weak model can lead to wrong decisions, so practical modelling skills are extremely important.
Why Use Python and Excel Together?
Excel and Python are not enemies. They solve different problems.
Excel is useful because it is visual, familiar and widely used in finance teams. It allows users to see formulas, assumptions, tables and outputs clearly.
Python is useful because it can automate repetitive work, process large datasets, run statistical models and build scalable workflows.
The best approach is to use both.
Excel is strong for:
- Model layout
- Assumption building
- Formula-based calculations
- Dashboards
- Scenario analysis
- Business review
- Presentation-ready outputs
Python is strong for:
- Data cleaning
- Automation
- Large dataset handling
- Statistical analysis
- Risk modelling
- Machine learning
- Repetitive calculations
- Report generation
The honest truth is simple: knowing only Excel is limiting, and knowing only Python without finance logic is also weak. A strong finance professional should understand both.
Financial Modelling Using Excel
Excel remains one of the most widely used tools in finance. It is used in corporate finance, investment banking, equity research, credit analysis, business finance, budgeting and risk reporting.
Excel is useful for financial modelling because it allows learners to build models step by step. Users can see assumptions, calculations and outputs in one place.
Important Excel modelling skills include:
- Financial formulas
- Data tables
- Pivot tables
- Scenario analysis
- Sensitivity analysis
- Forecasting models
- Valuation models
- Financial statement models
- Loan models
- Risk dashboards
- Model formatting
- Formula auditing
Excel is especially useful for business users because models can be reviewed and understood easily by finance teams, managers and decision-makers.
Financial Modelling Using Python
Python is becoming highly valuable in finance because it can handle tasks that are difficult or time-consuming in Excel.
Python helps finance professionals automate work, analyse financial datasets and build models that can be repeated with new data.
Python can be used for:
- Financial data cleaning
- Revenue forecasting
- Expense analysis
- Credit risk modelling
- Portfolio analytics
- Value at Risk calculation
- Regression analysis
- Machine learning for finance
- Excel automation
- Financial report generation
- Risk dashboard preparation
Python is especially useful when the model requires large datasets, repeated calculations or automated reporting.
Key Areas Where Python and Excel Are Used in Financial Modelling
Revenue Forecasting
Revenue forecasting is one of the most common financial modelling tasks. Excel can be used to build a structured forecast using assumptions such as sales growth, pricing, customer demand and seasonality.
Python can support revenue forecasting by analysing historical data, identifying growth trends and automating forecast calculations.
Together, Python and Excel can help build faster and more reliable forecasting models.
Expense Budgeting
Expense budgeting helps businesses plan and control costs. Excel is useful for department-wise budgets, monthly expense planning and variance analysis.
Python can help when expense data comes from multiple files or systems. It can clean data, categorise expenses and generate summary reports automatically.
This combination is useful for finance teams that handle large volumes of expense data.
Financial Statement Modelling
Financial statement modelling includes income statement, balance sheet and cash flow statement projections. Excel is widely used for this because it provides a clear structure for linked financial statements.
Python can support financial statement modelling by importing data, calculating trends, automating repetitive updates and preparing clean outputs for Excel models.
Valuation Modelling
Valuation models help estimate the value of a company, project or investment. Excel is commonly used for discounted cash flow models, comparable company analysis and scenario-based valuation.
Python can make valuation work more efficient by running multiple scenarios, automating calculations and comparing different assumptions quickly.
Credit Risk Modelling
Credit risk modelling is used by banks, NBFCs and fintech lenders to assess borrower risk and predict default.
Excel can be used to build simple credit scoring models, borrower assessment sheets and risk dashboards.
Python can be used for more advanced credit risk modelling such as logistic regression, Probability of Default estimation, credit scorecards and portfolio risk analysis.
Important credit risk topics include:
- Probability of Default
- Loss Given Default
- Exposure at Default
- Credit scoring
- Borrower risk classification
- Loan portfolio analysis
- IFRS 9 expected credit loss
- Model validation
This is one of the most practical applications of Python and Excel in finance.
Market Risk Modelling
Market risk modelling measures potential losses caused by changes in market prices, interest rates, currencies, commodities and volatility.
Excel can be used to calculate basic returns, volatility and Value at Risk.
Python can handle larger market datasets and calculate more advanced risk metrics such as rolling volatility, historical VaR, parametric VaR, Monte Carlo VaR and backtesting results.
Important market risk topics include:
- Value at Risk
- Volatility analysis
- Portfolio risk
- Stress testing
- Backtesting
- Interest rate risk
- Scenario analysis
Portfolio Analytics
Portfolio analytics helps investors and finance professionals understand portfolio return, volatility, correlation and diversification.
Excel is useful for basic portfolio calculations and visual dashboards.
Python is useful for analysing large asset datasets, calculating portfolio metrics and testing portfolio strategies.
Portfolio analytics may include:
- Portfolio return
- Portfolio volatility
- Asset correlation
- Diversification impact
- Sharpe ratio
- Risk contribution
- Efficient frontier basics
- Portfolio optimisation
Financial Analytics and Dashboards
Financial analytics helps convert data into useful business insights. Excel dashboards are useful for presenting key metrics clearly.
Python can prepare the data behind the dashboard by cleaning, combining and analysing different datasets.
This is useful for:
- Business performance tracking
- Risk reporting
- Management dashboards
- Financial KPIs
- Portfolio monitoring
- Credit risk reporting
- Forecasting reports
