While browsing a variety of websites, I kept finding that the same financial metric can greatly vary per source and so do the financial statements reported while little information is given how the metric was calculated.
For example, Microsoft’s Price-to-Earnings (PE) ratio on the 6th of May, 2023 is reported to be 28.93 (Stockopedia), 32.05 (Morningstar), 32.66 (Macrotrends), 33.09 (Finance Charts), 33.66 (Y Charts), 33.67 (Wall Street Journal), 33.80 (Yahoo Finance) and 34.4 (Companies Market Cap). All of these calculations are correct, however the method applied varies leading to different results. Therefore, collecting data from multiple sources can lead to wrong interpretation of the results given that one source could be applying a different calculation method than another. And that is, if it is even freely available. Often the calculation is hidden behind a paid subscription.
This is why I designed the FinanceToolkit, this is an open-source toolkit in which all relevant financial ratios (100+), indicators and performance measurements are written down in the most simplistic way allowing for complete transparency of the calculation method (proof). This allows you to not have to rely on metrics from other providers and, given a financial statement, allow for efficient manual calculations. This leads to one uniform method of calculation being applied that is available and understood by everyone.
The Finance Toolkit is complimented very well with the Finance Database 🌎, a database that features 300.000+ symbols containing Equities, ETFs, Funds, Indices, Currencies, Cryptocurrencies and Money Markets. By utilising both, it is possible to do a fully-fledged competitive analysis with the tickers found from the FinanceDatabase inputted into the FinanceToolkit.
Before installation, consider starring the project on GitHub which helps others find the project as well. Click the image to visit the repository and Star the project.
To install the FinanceToolkit it simply requires the following:
pip install financetoolkit
Then within Python use:
from financetoolkit import Toolkit
To be able to get started, you need to obtain an API Key from FinancialModelingPrep. This is used to gain access to 30+ years of financial statement both annually and quarterly. Note that the Free plan is limited to 250 requests each day, 5 years of data and only features companies listed on US exchanges.
Through the link you are able to subscribe for the free plan and also premium plans at a 15% discount. This is an affiliate link and thus supports the project at the same time. I have chosen FinancialModelingPrep as a source as I find it to be the most transparent, reliable and at an affordable price. I have yet to find a platform offering such low prices for the amount of data offered. When you notice that the data is inaccurate or have any other issue related to the data, note that I simply provide the means to access this data and I am not responsible for the accuracy of the data itself. For this, use their contact form or provide the data yourself.
How-To Guides for the FinanceToolkit
This section contains a list of How-To guides for the Finance Toolkit. These guides are meant to show you how to use the Finance Toolkit and how to perform a financial analysis. The guides are written in the form of Jupyter Notebooks. You can view the notebooks by clicking on the button below the description.
Getting Started with the Finance Toolkit
The Finance Toolkit offers a comprehensive set of tools designed to empower users with in-depth insights into the world of finance. By demonstrating each functionality and its practical application. This notebook will show you how to get started with the Finance Toolkit.
Visit the Code Documentation
Besides the practical examples, there exists a fully fledged documentation of the code. This documentation contains a description of each function, its parameters and an example. This allows you to quickly find the function you are looking for and understand how to use it.
The Finance Database and the Finance Toolkit
This Notebooks demonstrates how to use the Finance Toolkit with the Finance Database to perform a complete financial analysis. Through the Finance Database you are able to find companies that are in the same country, sector and industry as the company you are analysing. This allows you to perform a complete competitive analysis with the help of the Finance Toolkit.
Creating Custom Ratios
The Finance Toolkit has an abundance of financial ratios, however it could be that you are looking for a specific ratio that is currently not provided. First and foremost, I encourage you to create a Pull Request to add these ratios in but there is also an option to add custom ratios as follows. This feature was designed by sword134.
Calling Functions Directly
If you possess your own financial statements data or have a different particular use-case in mind, it could be that you wish to directly use the functions in the FinanceToolkit. This Notebook illustrates the process of accomplishing this.
Using External Datasets
The Finance Toolkit has the ability to leverage custom datasets from any data provider as well. This makes it possible to work with your preferred data and not be limited to the data source the Finance Toolkit currently provides. With this, it is possible to work with datasets from Yahoo Finance, OpenBB, Quandl, EODH, Bloomberg and much more.
The Finance Toolkit features the following functionality, also see Basic Usage to see some of these functions in action:
- Company profiles (
get_profile), including country, sector, ISIN and general characteristics (from FinancialModelingPrep)
- Company quotes (
get_quote), inclufding 52 week highs and lows, volume metrics and current shares outstanding (from FinancialModelingPrep)
- Company ratings (
get_rating), based on key indicators like PE and DE ratios (from FinancialModelingPrep)
- Historical market data (
get_historical_data), which can be retrieved on a daily, weekly, monthly, quarterly and yearly basis. This includes OHLC, dividends, returns, cumulative returns and volatility calculations for each corresponding period. (from Yahoo Finance)
- Treasury Rates (
get_treasury_data) for several months and several years over the last 3 months which allows yield curves to be constructed (from Yahoo Finance)
- Analyst Estimates (
get_analyst_estimates) that show the expected EPS and Revenue from the past and future from a range of analysts (from FinancialModelingPrep)
- Earnings Calendar(
get_earnings_calendar) which shows the exact dates earnings are released in the past and in the future including expectations (from FinancialModelingPrep)
- Revenue Geographic Segmentation (
get_revenue_geographic_segmentation) which shows the revenue per company from each country and Revenue Product Segmentation (
get_revenue_product_segmenttion) which shows the revenue per company from each product (from FinancialModelingPrep)
- Balance Sheet Statements (
get_balance_sheet_statement), Income Statements (
get_income_statement), Cash Flow Statements (
get_cash_flow_statement) and Statistics Statements (
get_statistics_statement), obtainable from FinancialModelingPrep or the source of your choosing through custom input. These functions are accompanied with a normalization function so that for any source, the same ratio analysis can be performed. Please see this Jupyter Notebook that explains how to use a custom source.
- Efficiency ratios (
ratios.collect_efficiency_ratios), liquidity ratios (
ratios.collect_liquidity_ratios), profitability ratios (
ratios._collect_profitability_ratios), solvency ratios (
ratios.collect_solvency_ratios) and valuation ratios (
ratios.collect_valuation_ratios) functionality that automatically calculates the most important ratios (50+) based on the inputted balance sheet, income and cash flow statements. Any of the underlying ratios can also be called individually such as
ratios.get_return_on_equity. Next to that, it is also possible to input your own custom ratios (
ratios.collect_custom_ratios). See also this Notebook for more information.
- Models like DUPONT analysis (
models.get_extended_dupont_analysis) or Enterprise Breakdown (
models.get_enterprise_value_breakdown) that can be used to perform in-depth financial analysis through a single function. These functions combine much of the functionality throughout the Toolkit to provide advanced calculations.
- Performance metrics like Jensens Alpha (
performance.get_jensens_alpha), Capital Asset Pricing Model (CAPM) (
performance.get_capital_asset_pricing_model) and (Rolling) Sharpe Ratio (
performance.get_sharpe_ratio) that can be used to understand how each company is performing versus the benchmark and compared to each other.
- Risk metrics like Value at Risk (
risk.get_value_at_risk) and Conditional Value at Risk (
risk.get_conditional_value_at_risk) that can be used to understand the risk profile of each company and how it compares to the benchmark.
- Technical indicators like Relative Strength Index (
technicals.get_relative_strength_index), Exponential Moving Average (
technicals.get_exponential_moving_average) and Bollinger Bands (
technicals.get_bollinger_bands) that can be used to perform in-depth momentum and trend analysis. These functions allow for the calculation of technical indicators based on the historical market data.
The dependencies of the package are on purpose very slim so that it will work well with any combination of packages and not result in conflicts.
This section is an introduction to the Finance Toolkit. Also see this notebook for a detailed Getting Started guide as well as this notebook that includes the Finance Database 🌎 and a proper financial analysis.
from financetoolkit import Toolkit companies = Toolkit(['AAPL', 'MSFT'], api_key="FINANCIAL_MODELING_PREP_KEY", start_date='2017-12-31') # a Historical example historical_data = companies.get_historical_data() # a Financial Statement example balance_sheet_statement = companies.get_balance_sheet_statement() # a Ratios example profitability_ratios = companies.ratios.collect_profitability_ratios() # a Models example extended_dupont_analysis = companies.models.get_extended_dupont_analysis() # a Performance example capital_asset_pricing_model = companies.performance.get_capital_asset_pricing_model(show_full_results=True) # a Risk example value_at_risk = companies.risk.get_value_at_risk(period='quarterly') # a Technical example bollinger_bands = companies.technicals.get_bollinger_bands()
Generally, the functions return a DataFrame with a multi-index in which all tickers, in this case Apple and Microsoft, are presented. To keep things manageable for this README, I’ve selected just Apple but in essence it can be any list of tickers (no limit). The filtering is done through using
.xs('AAPL', level=1, axis=1) based on whether it’s fundamental data or historical data respectively.

Obtaining Financial Ratios
Get Profitability Ratios based on the inputted balance sheet, income and cash flow statements. This can be any of the 50+ ratios within the
ratios module. The
get_ functions show a single ratio whereas the
collect_ functions show an aggregation of multiple ratios.

|Return on Equity||nan||0.4936||0.5592||0.7369||1.4744||1.7546|
Obtaining Performance Metrics
Get the Expected Return as defined by the Capital Asset Pricing Model. Here with the
show_full_results=True parameter not only the expected return is found but also the Betas. The beauty of this is that it can be based on any period as the function also accepts the period ‘weekly’, ‘monthly’, ‘quarterly’ and ‘yearly’ (as shown below).
|Date||Risk Free Rate||Beta AAPL||Beta MSFT||Benchmark Returns||CAPM AAPL||CAPM MSFT|
Obtaining Risk Metrics
Get the Value at Risk for each quarter. Here, the days within each quarter are considered for the Value at Risk. This makes it so that you can understand within each period what is the expected Value at Risk (VaR) which can again be any period but also based on distributions such as Historical, Gaussian, Student-t, Cornish-Fisher.
Obtaining Technical Indicators
Get Bollinger Bands based on the historical market data. This can be any of the 30+ technical indicators within the
technicals module. The
get_ functions show a single indicator whereas the
collect_ functions show an aggregation of multiple indicators.
|Date||Lower Band||Middle Band||Upper Band|
