What this calculator answers
Allocate one total stake across several selections in the same market so that each winning selection returns the same gross amount before charges.
Formula and worked example
Formula: Inverse total = sum of 1 divided by each price. Stake i = total stake times (1 divided by price i) divided by inverse total.
For 60.00 across 2.00, 3.00 and 4.00, the inverse total is 1.08333. The calculation shows that these prices do not cover the market below 100 percent, so the equal gross return is below the total stake.
Checks before using the result
- Using selections from different markets.
- Rounding each stake without checking the new total.
- Treating equal gross return as equal net outcome after charges.
When the calculation does not apply
It needs mutually exclusive selections and current prices. It does not allow for deductions, charges, limits or a selection being withdrawn.
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, Expected value or Parlay odds 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.
