Calculate the capital expenditure coverage ratio, a solvency ratio that measures a company’s ability to cover its capital expenditures with its cash flow from operations.

The capex coverage ratio evaluates a company’s ability to fund its capital expenditures, which are essential for maintaining and growing its business, using the cash generated from its operations. A higher ratio indicates a stronger ability to fund capital investments from operating cash flow.

The formula is as follows:

\[\text{Capital Expenditure Coverage Ratio} = \text{Cash Flow from Operations} / \text{Capital Expenditure}\]

Also known as: capital expenditure coverage.

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

Calculate the CAPEX Coverage Ratio in Python

The CAPEX Coverage Ratio is available in the Ratios module of the open-source Finance Toolkit. Install it with:

pip install financetoolkit -U

Then call get_capex_coverage_ratio as shown below.

from financetoolkit import Toolkit

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

capex_coverage_ratios = toolkit.ratios.get_capex_coverage_ratio()

Which returns:

  2021 2022 2023 2024 2025
AAPL 9.3855 11.4075 10.087 12.5176 8.7678
TSLA 1.4346 2.053 1.4896 1.3157 1.7294

Parameters

get_capex_coverage_ratio accepts the following parameters:

  • 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.
