Book Value per Share
Calculate the book value per share, a valuation ratio that measures the amount of common equity value per share outstanding.
The book value per share is a fundamental valuation metric that reflects the net worth of a company attributed to each outstanding share of common stock.
The formula is as follows:
\[\text{Book Value per Share} = (\text{Total Shareholder Equity} - \text{Preferred Stock}) / \text{Weighted Average} (\text{Diluted}) \text{Shares}\]Also known as: BVPS, net asset value per share.
Book Value per Share in Python or via the MCP
Install the Finance Toolkit with:
pip install financetoolkit -U
Then call get_book_value_per_share as shown below.
from financetoolkit import Toolkit
toolkit = Toolkit(
["CB", "TRV", "ALL"],
api_key="FINANCIAL_MODELING_PREP_KEY",
start_date="2021-01-01",
end_date="2025-12-31",
)
toolkit.ratios.get_book_value_per_share()
Or, after setting up the Finance Toolkit MCP, ask:
How did the book value per share of Chubb, Travelers and Allstate develop from 2021 to 2025?
Which returns:
| 2021 | 2022 | 2023 | 2024 | 2025 | |
|---|---|---|---|---|---|
| ALL | 77.5961 | 57.2198 | 60.0724 | 72.5952 | 108.081 |
| CB | 134.734 | 119.282 | 143.666 | 155.426 | 186.02 |
| TRV | 115.179 | 89.9458 | 107.326 | 120.571 | 144.525 |
Parameters
get_book_value_per_share accepts the following parameters.
| Parameter | Type | Description | Example |
|---|---|---|---|
diluted | bool | Whether to use diluted shares in the calculation. Defaults to True. | False |
rounding | int | None | The number of decimals to round the results to. Defaults to None, which uses the rounding of the Toolkit (4 unless set otherwise). | 2 |
growth | bool | Whether to calculate the growth of the ratios. Defaults to False. | True |
lag | int | list[int] | The lag to use for the growth calculation. Defaults to 1. | 4 |
compound | bool | Whether the growth is the compound annual growth rate over the lag (e.g. lag=5 for the five-year CAGR) instead of the total change. Defaults to False. | False |
standardize | bool | Whether to standardize (Z-Score) the result. When combined with growth=True, standardizes the growth values instead of the raw values. Defaults to False. | True |
trailing | int | The number of periods to sum flows (income and cash flow statement items) over, with balance sheet items averaged over the same number of period ends. E.g. 4 with quarterly data gives the trailing twelve months (TTM) and 3 with annual data a three-year cumulative figure. Defaults to None, which uses single-period flows (per quarter and not annualized with quarterly data). | 4 |
