Calculate the EV to free cash flow ratio, a valuation ratio that compares a company’s enterprise value (EV) to its free cash flow.

Unlike EV to Operating Cash Flow, this ratio nets out capital expenditures, giving a valuation multiple based on the cash actually available to all capital providers after reinvestment in the business.

The formula is as follows:

\[\text{EV to Free Cash Flow Ratio} = \text{Enterprise Value} / \text{Free Cash Flow}\]

Also known as: EV/FCF.

No programming experience? With the Finance Toolkit MCP server, AI assistants such as Claude and ChatGPT can calculate the EV to Free Cash Flow Ratio for you. Just ask in plain English.

Calculate the EV to Free Cash Flow Ratio in Python

The EV to Free Cash Flow Ratio is available in the Ratios module of the open-source Finance Toolkit. Install it with:

pip install financetoolkit -U

Then call get_ev_to_free_cash_flow_ratio as shown below.

from financetoolkit import Toolkit

toolkit = Toolkit(["AAPL", "TSLA"], api_key="FINANCIAL_MODELING_PREP_KEY")

ev_to_fcf_ratio = toolkit.ratios.get_ev_to_free_cash_flow_ratio()

Which returns:

  2021 2022 2023 2024 2025
AAPL 33.3102 20.0107 31.5146 36.2809 42.075
TSLA 340.351 55.4475 197.279 393.991 253.891

Parameters

get_ev_to_free_cash_flow_ratio accepts the following parameters:

  • show_daily (bool, optional): Whether to show daily data. Defaults to False.
  • diluted (bool, optional): Whether to use diluted shares in the calculation. Defaults to True.
  • rounding (int, optional): The number of decimals to round the results to. Defaults to 4.
  • growth (bool, optional): Whether to calculate the growth of the ratios. Defaults to False.
  • lag (int | str, optional): The lag to use for the growth calculation. Defaults to 1.
  • standardize (bool, optional): Whether to standardize (Z-Score) the result. When combined with growth=True, standardizes the growth values instead of the raw values. Defaults to False.
  • trailing (int): Defines whether to select a trailing period. E.g. when selecting 4 with quarterly data, the TTM is calculated.

The Ratios module page introduces the module, and the sidebar lists all of its functions.
