Formula Used

  • Vested Units = Total Granted Units × (Vested % ÷ 100)
  • Accelerated Units = (Total Granted Units − Vested Units) × (Acceleration % ÷ 100)
  • Eligible Units = Vested Units + Accelerated Units
  • Effective Buyout Price = Offer Price × (1 + Pricing Adjustment % ÷ 100)
  • Gross Sale Value = Eligible Units × Effective Buyout Price
  • Exercise Cost = Eligible Units × Strike Price for options, otherwise 0
  • Gross Buyout Value = Gross Sale Value − Exercise Cost
  • Ordinary Taxable Amount = Gross Buyout Value × (1 − Capital-Gain Share %)
  • Capital Taxable Amount = Gross Buyout Value × Capital-Gain Share %
  • Total Taxes = Ordinary Taxable Amount × Ordinary Tax Rate + Capital Taxable Amount × Capital-Gains Tax Rate
  • Transaction Fees = Gross Buyout Value × Fee Rate
  • Net Proceeds = Gross Buyout Value − Total Taxes − Transaction Fees

FAQs

1) What is an equity buyout?

An equity buyout is a cash offer for employee shares, options, or RSUs. It often appears during acquisitions, tender offers, recapitalizations, or secondary liquidity events.

2) Can this calculator handle RSUs and stock options?

Yes. Choose the award class first. Options subtract exercise cost, while RSUs and direct shares treat the full effective price as the payout basis.

3) What does acceleration mean here?

Acceleration means some unvested awards become eligible because of a deal event. Enter the percentage of unvested units that will vest early under your agreement.

4) Why is there a capital-gain share field?

Some payouts are not taxed entirely as ordinary income. This field lets you model a mixed tax profile when a portion may receive capital-gains treatment.

5) What is the pricing adjustment percentage?

It adjusts the offered unit value up or down. Use it for negotiated premiums, tender discounts, escrow impacts, or conservative scenario planning.

6) Does the calculator include exercise cost?

Yes, for options. The tool subtracts exercise cost from gross sale value before taxes and fees, which gives a more realistic buyout estimate.

7) Can I use this for acquisition planning?

Yes. It is useful for acquisition offers, tender events, internal repurchases, and secondary sales where employees want a quick net-proceeds estimate.

8) Is this a substitute for legal or tax advice?

No. This is an educational estimate. Final tax treatment, withholding, plan rules, and acceleration clauses should be reviewed with qualified advisers.
