Convertible bond conversion ratio

How many shares correspond to one bond at the contractual conversion price?

When to use it and why it works

A holder exchanges bond face value for shares at the conversion price. Divide the face amount of one bond by the amount needed per share to obtain shares per bond.

Conversion ratio = face value / conversion price

Work through an example

A bond has face value 100 and converts at 20 per share. How many shares correspond to it?

Read this example’s explanation

100 ÷ 20 = 5 shares per bond.

Turn the question into inputs

Positive face amount of one bond, not its market purchase price.
Allowed range: ≥ 0.000001

Positive contractual price per share applicable on the conversion date, in the same currency as face value.
Allowed range: ≥ 0.000001

Your calculated answer

Conversion ratio (shares per bond)
5

Follow each step

  1. Divide face value per bond by the conversion price per share.

    100 / 20 = 5

Intermediate calculations retain precision; displayed values are rounded. Follow the precision requested by your question.

What the result means

The ratio tells you the shares corresponding to face value. Profitability also depends on the share price, bond purchase cost, and issue terms.

Mistakes to watch for

  • Do not substitute the bond’s trading price for face value or the stock’s market price for its conversion price.
  • This lesson retains theoretical fractional shares. Actual whole-share rounding, cash settlement, and conversion-price adjustments follow the issue terms.

Try another question on your own

Change face value to 1,000 and conversion price to 25. Find the ratio.

Set up the formula first. Answers rounded to two decimals are accepted; use six decimals for absolute values below 0.01. For percentages, enter the number before the percent sign.

How to use this calculator

Enter Solve for, Bond face value, Conversion price, and Conversion ratio.

Review the model boundary before calculating: Issue terms can adjust the conversion price or ratio after corporate actions.

Read Conversion ratio, Conversion price, Whole shares, and Unconverted principal, then compare the result with the cited source and governing product terms.

Formula

Formula used: CR = FVbond / CP; CP = FVbond / CR. Percentages are converted to decimals before calculation.

Worked example

Example: with Bond face value = 1,000, and Conversion price = 40, the calculated Conversion ratio is 25.

Assumptions and limits

  • Issue terms can adjust the conversion price or ratio after corporate actions.
  • Inputs are manual and the calculator does not retrieve live bond or share prices.
  • Recheck dated source rules, product documents, and market conventions before relying on the result.
