Guide of This Tool

How to use it

Choose a mode, enter promoter shares and total shares, then click calculate. Use Compare mode to evaluate change over time and Dilution mode to estimate the effect of fresh share issuance.

What it shows

The tool displays promoter holding ratio, public holding, change versus previous ownership, and a visual ownership meter so users can understand the result quickly.

Best practice

Use consistent units for every share value. If you enter promoter shares in crores, total and previous values should also be entered in crores for correct output.

Facts of This Tool

Direct percentage logic

Promoter holding ratio is a pure ownership percentage metric. It does not require price, market cap, or profit figures to calculate the core ratio.

Dilution matters

Promoter shares can remain constant while promoter holding falls if the total number of outstanding shares rises after issuance or conversion.

Comparison adds context

A single percentage is useful, but a previous-period comparison often reveals whether ownership is increasing, stable, or being diluted over time.

Additional Tips of This Tool

  • Use Compare mode for quarter-on-quarter or year-on-year review.
  • Use Dilution mode before fundraising analysis or ESOP expansion modeling.
  • Copy the summary after calculation for reports or investor notes.
  • If promoter shares increase but total shares also rise sharply, the final ratio may still stay flat.
  • Public holding is simply the remaining ownership after promoter holding is deducted from 100%.
  • Save a consistent naming format in the Company field for clean internal documentation.
  • Use the notes field for funding round labels, reporting periods, or assumptions.
  • When data is incomplete, begin with Current Ratio mode first.
  • Use the example cards below for instant testing.
