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 shows the arithmetic. It doesn't tell you whether the price fits your read of the outcome or your budget. Decide the stake before you enter it. Check the market rules. Keep essential money out of it entirely.

Cross-check on a second tool. The calculator hub, System bet or Overround and margin cover the same numbers from a different angle. Same price conventions, so a decimal price in one is a decimal price in the other.

Read the odds format guide if you're new to the formats. Two minutes.

Reading a rounded result

Money is rounded to two decimals here. A real settlement applies its own rounding sequence, which can differ. Keep the original inputs written down if you're going to check the number later.

Unclear about an input? Find the stated market term. Don't guess. A quick sanity check: change one input by a small amount and see whether the result moves the way you expect.

That doesn't validate the market. It can flag a reversed sign, a mis-entered price format or a duplicated stake. Use the number to understand the arithmetic. It's not a reason to ignore a limit you set in advance.
