How to Calculate Required External Financing With Dividend Payouts

Any single dividend payout reveals the amount of equity that a company has. The dividend payout is a fraction of the company's net income, and the size of the fraction depends on how much equity the investor has contributed with respect to the company's total equity. When a company has a target level of equity that they want for operations, the external financing they need is the difference between that level and their current equity.

Divide the value of an investor's dividends by the company's net income for the period. For example, if someone who has invested $500 with a company making a net income of $3,000 receives $40 in dividends, divide $40 by $3,000, giving 0.0133.

Divide the equity that the investor has contributed by this ratio. Continuing the example, divide $500 by 0.0133, giving $37,593.98. This is the company's current equity level.

 

Subtract this level from the value of the equity that the company needs. For example, if the company wants to accumulate $50,000 of equity, subtract $37,593.98 from $50,000, giving $12,406.02. This is the value of the company's required external financing.
