Total stake Leg one decimal odds Leg two decimal odds Leg three decimal odds Leg four decimal odds, optional

Example result

10.00 at 1.80, 2.00 and 2.50 gives 9.00 combined odds and 90.00 payout.

What this calculator answers

Multiply up to ten active decimal prices to find a combined price and return from a single total stake. Leave unused legs blank.

Formula and worked example

Formula: Combined decimal odds = product of every active leg price. Payout = total stake multiplied by combined decimal odds.

A 10.00 stake on 1.80, 2.00 and 2.50 gives combined odds of 9.00 and a payout of 90.00. The profit is 80.00 after subtracting the stake.

Checks before using the result

• Adding prices rather than multiplying them.
• Entering an American price in a decimal field.
• Leaving a non runner at its original price.

When the calculation does not apply

It applies to a simple all-win combined bet. A void leg, cash out, revised price or special settlement term can change the final calculation.

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 Margin of victory and Bet return, or read the guide to reading odds. 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.
