This is an estimate for the small-shareholder (tender-offer) route only — the general (non-small-shareholder) category is typically accepted at a much lower proportionate ratio. The real acceptance ratio is only known after the buyback closes and the registrar finalises the basis of acceptance.

How the Buyback Acceptance Ratio Calculator works

Under SEBI's Buyback Regulations, 15% of every tender-offer buyback is reserved for “small shareholders” — anyone holding shares of market value ₹2,00,000 or less in that company as on the record date. If small shareholders collectively tender more shares than the reserved quota can cover, each small-shareholder application is accepted proportionately: acceptance ratio = shares reserved for small shareholders ÷ total shares tendered by small shareholders, capped at 100%.

The total shares tendered by your category is only known for certain after the buyback window closes — this calculator lets you plug in an estimate (from news coverage of similar past buybacks, or once interim tender figures are reported) to get an indicative acceptance ratio before the final numbers are out. The general (non-small shareholder) category is accepted from the remaining 85% and typically sees a much lower ratio when a buyback is heavily oversubscribed.
