Convertible bonds and hybrid securities can be attractive investment options, offering both fixed-income stability and equity upside potential. However, one of the most important metrics investors need to understand before making a decision is the conversion premium.
The Conversion Premium Calculator makes this analysis simple. It helps investors quickly determine how much extra they are paying for the privilege of converting a bond into stock compared to buying the stock directly.
This tool is especially useful for traders, portfolio managers, and students of finance who want to evaluate whether a convertible bond is worth its price.
What is a Conversion Premium?
The conversion premium measures how much more an investor pays for a convertible bond compared to buying the underlying stock outright.
It is expressed as a percentage and calculated using the formula: Conversion Premium (%)=Convertible Bond Price – Conversion ValueConversion Value×100\text{Conversion Premium (\%)} = \frac{\text{Convertible Bond Price – Conversion Value}}{\text{Conversion Value}} \times 100Conversion Premium (%)=Conversion ValueConvertible Bond Price – Conversion Value×100
Where:
- Convertible Bond Price = Market price of the bond.
- Conversion Value = Market value of the stock obtained if the bond is converted.
Why is the Conversion Premium Important?
- Evaluates Attractiveness: Shows whether the convertible bond is priced fairly compared to the stock.

- Stock Price: $50
- Conversion Ratio: 20 shares
Step 1: Calculate Conversion Value 20×50=1,00020 \times 50 = 1,00020×50=1,000
Step 2: Calculate Conversion Premium (1,200−1,000)1,000×100=20%\frac{(1,200 – 1,000)}{1,000} \times 100 = 20\%1,000(1,200−1,000)×100=20%
Result:
- Conversion Value = $1,000
- Conversion Premium = 20%
This means the bondholder is paying a 20% premium compared to directly buying the shares.
