Example result

Three winning legs at 2.00 return 80.00 from a 10.00 stake.

What this calculator answers

Build a combined price for up to ten selections. Winning legs remain at their price, void and non runner legs become 1.00, and place legs use the entered place price.

Formula and worked example

Formula: Combined decimal odds = product of active leg decimal odds. Return = stake multiplied by combined decimal odds.

A 10.00 stake with three winning legs at 2.00 has combined odds of 8.00 and returns 80.00. A void leg leaves the other active prices unchanged.

Checks before using the result

• Leaving an unused leg at 0.00 instead of blank.
• Using win odds for a place result without entering place odds.
• Assuming every non runner is treated identically across markets.

When the calculation does not apply

It does not model every multi settlement rule. Check how a particular market handles a late withdrawal, reduction or revised price.

Keep the number in context

A calculator makes the arithmetic visible, but it does not decide whether a price fits your budget or information. Write down the stake before placing anything, check the market rules, and keep essential money separate. The result is a planning figure, not a prediction of what will happen.

For another view, visit the calculator hub, compare the System bet and Overround and margin, or read the odds format guide. These tools use the same price conventions, so you can check a number from more than one angle.

Reading a rounded result

Displayed money amounts are rounded to two decimal places, while a real settlement can apply its own rounding sequence. Keep the original inputs beside the result if you need to repeat the calculation later.

If an input is unclear, pause and find the stated market term rather than guessing. A useful check is to change one input by a small amount and see whether the result moves in the direction you expect.

That does not validate the market, but it can reveal a reversed sign, an incorrect price format or a duplicated stake. Use the final figure as an aid to understanding the arithmetic, not as a reason to ignore a limit you set in advance.
