Multiple methods exist to calculate goodwill depending on business context, profit pattern, and expectations.
Straight average profit – Easy but doesn’t reflect time value.
Super profit – Focuses on excess earnings.
Capitalisation – Converts expected profits into capital value.
Annuity method of goodwill – Accounts for time value and consistency of super profits.
Choice of method depends on business nature and stability of income.
The annuity method of valuation of goodwill – Decoded
The annuity method of goodwill calculates the present value of future super profits using an annuity factor. It’s more accurate because it reflects the reduced value of money over time. Businesses expecting consistent surplus profits for a set period often prefer this method for a fairer valuation of goodwill.
The calculation of super profit
Super profit is the amount earned over and above the normal expected profit. It’s a key input for the annuity method of goodwill.
To calculate:
Super profit = Average actual profit – Normal profit
Where Normal Profit = Capital Employed × Normal Rate of Return (%)
Calculation of Super Profit as per the Annuity Method
When applying the annuity method of goodwill, super profit is calculated first. Then, it is multiplied by the annuity factor for the given years and interest rate.
Goodwill = Super profit × annuity factor
This provides the present value of future super profits — a more time-sensitive and accurate valuation.
