Business valuation workbook

Connect company history to a reviewed discounted cash-flow model. Check whether a company fits the method before producing a valuation.

ExcelFinancial modellingData validation

A complete company list is not a valuation-ready dataset.

Question
How can a NIFTY 100 history workbook prevent unsupported operating cash-flow valuations?

Observed project audit: 100 company exports matched to the official constituent snapshot retrieved on 7 October 2026. This is a static snapshot, not a live market feed.

Supported finding

The final workbook classifies 69 of 100 companies as conditionally eligible for operating FCFF and blocks 31. Even the 69 need reviewed assumptions before a value is available.

Decision implication

Review method suitability, reporting basis and period coverage first. Then define operating assumptions and the enterprise-to-equity bridge. A downloaded company history alone cannot justify a price target.

Limitation

Provider summaries are not a complete filing-level archive. Reporting durations and several valuation inputs remain unresolved. Native Excel tests establish calculation mechanics, not investment suitability or an independent financial audit.

What the workbook checks

Observed counts from the final Company Registry. The rows below are mutually exclusive, using the workbook's first blocking reason.

The reporting-basis inventory separately contains 92 consolidated, 4 standalone and 4 unverified exports. These counts overlap other method blocks and must not be added to the table. Matching date headings do not establish complete annual statements.

Preserve the original model

The workbook keeps the original model alongside a separate Company DCF sheet, company selector, source history, review flags and independent Base, Downside and Upside assumption rows.

Keep review gates visible

Missing inputs remain unavailable rather than zero. Unsupported methods and unresolved history block the new company valuation. Refresh All does not retrieve updated company data.

A fictional cash-flow example

A separate, source-free Python reference illustrates the new Company DCF method. All inputs are invented. Projection years are relative years 1 to 10, with no real company or market date.

Synthetic demonstration only. These values are not observed company results, forecasts, investment recommendations or the output of the private workbook.

Fictional Manufacturing Example starts with INR 1,000 crore revenue. Revenue grows 8% in each projection year; EBIT margin rises from 20% to 22%. The model uses 25% tax, depreciation at 3% of revenue, capex at 4%, and operating working capital at 12% of revenue. WACC is 11.6%; terminal growth is 3%.

WACC inputs are 7% risk-free rate, 6% equity risk premium, beta 1, 8% pretax cost of debt and 20% debt weight. The equity bridge adds 100 cash and 20 other assets, then subtracts 250 debt and leases, 15 non-controlling claims and 5 senior claims, all INR crore. Diluted shares are 100 crore. Every input is invented.

Full inputs, calculation code and all annual fields are in the reproduction ZIP. Saved outputs use twelve decimal places. The displayed precision supports calculation checking; it does not express valuation certainty.

Trace the assumptions before the output

Free cash flow to the firm, or FCFF, measures cash flow available to providers of capital before the equity bridge.

Ten-year model
Project annual revenue, transition the EBIT margin linearly to its year-10 target, apply tax without an immediate credit for operating losses, add depreciation, and subtract capital expenditure and the change in operating working capital. Discount each year's FCFF using WACC.
Terminal period
Calculate year-11 cash flow using terminal growth, including terminal reinvestment. WACC must exceed terminal growth. The perpetuity assumption is a model boundary, not evidence of sustainable growth.
Equity bridge and units
Enterprise value plus reviewed non-operating assets, less debt, leases, non-controlling interests and senior claims gives equity value. INR crore divided by diluted shares in crore gives INR per share. A negative equity result is retained.
Observed source scope
The private workbook uses the official NIFTY 100 constituent list and personally downloaded Screener exports. The constituent URL may change after the retained 7 October snapshot. Export documentation describes access; it does not grant public redistribution of company records. The provider's terms govern those materials.
Public/private boundary
This page publishes authored audit counts and a fictional model. Provider exports, company financial histories, the populated Excel workbook and its private evidence pack are excluded. Public visitors can reproduce the fictional calculation; they cannot independently replay the private source audit from this package.
Remaining limits
The original workbook's illustrative relative-valuation peers remain illustrative. Its legacy sensitivity sheet uses a different terminal-growth input reference from the original DCF and is not presented as repaired. The new Company DCF is separate. No independent human financial audit is claimed.

Reproduce the fictional model

A small downloadable source package demonstrates the calculation without third-party financial records.
