How to use this calculator

  1. 1Enter the purchase price and the net tangible assets included.
  2. 2Enter normalised earnings and a fair return rate on those assets.
  3. 3Compare residual goodwill with excess-earnings goodwill.

Two ways to test goodwill

Residual method: goodwill = purchase price − net tangible assets. This tells you what was paid, not whether it was justified.

Excess earnings method: apply a fair rate of return to net tangible assets, subtract that from normalised earnings, and capitalise whatever is left. If excess earnings are negative, the business supports no goodwill at all.

Personal vs transferable goodwill

Goodwill attached to the owner personally — their relationships, licence or reputation — largely evaporates on sale. Buyers pay for transferable goodwill: contracts, recurring customers, documented processes and a team that stays.

The practical test is whether the business could run for ninety days without the owner. Where it could not, expect goodwill to be heavily discounted or shifted into an earnout.

Frequently asked questions

Is goodwill tax deductible?

Treatment differs by country and deal structure. In many jurisdictions purchased goodwill is amortised for accounting but not deductible for tax — take local advice.

How many years of profit is normal for goodwill?

Small owner-operated businesses typically transact at one to three years of normalised earnings as goodwill; established businesses with recurring revenue reach four or more.

Can goodwill be negative?

Yes. If a business earns less than a fair return on its assets, a rational buyer pays below net asset value — a bargain purchase.
