Cost of New Equity Calculator
Raising capital is a pivotal decision for any growing business. When a company decides to issue new shares to finance operations or expansion, it incurs costs beyond just the share price. These additional costs—known as flotation costs—make new equity more expensive than using retained earnings. That's where the Cost of New Equity Calculator becomes essential.
This tool helps finance professionals, analysts, and business owners determine the true cost of raising capital through issuing new equity. It factors in expected dividends, stock price, growth expectations, and flotation costs to provide a more accurate figure than simply using the cost of internal equity.
Understanding this cost is vital for calculating the Weighted Average Cost of Capital (WACC) and for comparing funding options during strategic decision-making.
Formula
The formula used to calculate the cost of new equity is based on the Gordon Growth Model adjusted for flotation costs:
Cost of New Equity = (D₁ ÷ (P × (1 − F))) + g
Where:
- D₁ = Expected dividend in the next year
- P = Current stock price
- F = Flotation cost (as a decimal)
- g = Dividend growth rate (as a decimal)
This accounts for the fact that the firm receives less than the full market price due to issuance costs.
How to Use
Follow these steps to calculate your cost of new equity:
- Enter Expected Dividend (D₁): This is the projected dividend for the upcoming year.
- Enter Current Stock Price (P): This is the price at which new shares are expected to be issued.
- Enter Flotation Cost (F): The percentage cost of issuing the new equity (underwriting, legal, registration fees, etc.).
- Enter Growth Rate (g): The anticipated dividend growth rate as a percentage.
- Click “Calculate”: The calculator returns the cost of new equity in percentage form.
The result reflects the effective rate of return new investors will demand, factoring in issuance expenses.
Example
Assume a company plans to issue new equity with the following values:
- Expected dividend (D₁): $3.00
- Stock price (P): $60
- Flotation cost (F): 5%
- Growth rate (g): 6%
Using the formula:
Cost = (3 ÷ (60 × (1 − 0.05))) + 0.06 = (3 ÷ 57) + 0.06 ≈ 0.0526 + 0.06 = 0.1126 or 11.26%
Thus, the cost of new equity is 11.26%.
FAQs
1. What is the cost of new equity?
It’s the rate of return required by new shareholders, including costs of issuing new shares.
2. Why include flotation costs?
Because issuing new equity isn't free—underwriting, legal, and filing fees reduce the net proceeds.
3. How is this different from cost of internal equity?
Internal equity (retained earnings) doesn’t involve flotation costs, so it's typically cheaper.
4. What are flotation costs typically?
They can range from 3% to 10% depending on the company size and market conditions.
5. Can this calculator be used for preferred shares?
No. Preferred shares require a different formula based on fixed dividend and price.
6. What happens if flotation cost is 0%?
Then the formula simplifies to the traditional Gordon Growth Model for internal equity.
7. Is the cost of new equity always higher than internal equity?
Usually, yes. Flotation costs make new equity more expensive.
8. Why is the cost of equity important for WACC?
It determines how expensive it is to fund operations through equity compared to debt.
9. What happens if dividend or price inputs are 0?
The calculator will reject those as invalid, since they make the equation meaningless.
10. Should I include taxes in this calculation?
No, taxes are not deducted from equity returns (unlike debt).
11. Is the growth rate assumed to be constant?
Yes, this model assumes dividends grow at a constant rate.
12. How often should this be recalculated?
Whenever market price, dividends, or flotation costs change significantly.
13. Can it be used for IPO cost estimation?
Yes, especially for estimating how much return IPO investors might require.
14. Is this useful for startup companies?
Only if they pay dividends and have a predictable growth rate, which many startups do not.
15. Can I manually compute this in Excel?
Yes, using the formula and basic cell math functions.
16. How accurate is the Gordon Model?
It’s a simplified approach and works best for stable, dividend-paying firms.
17. Can flotation costs ever be negative?
No. They are always a cost—never a gain.
18. Is this relevant for secondary offerings?
Yes, any issuance of new shares incurs flotation costs, making this formula relevant.
19. Can I use this for share buybacks?
No, the formula is for raising equity, not retiring it.
20. Is dividend reinvestment considered here?
No. The model assumes dividends are paid out, not reinvested.
