Accumulator calculator

Add the odds for each selection in your multibet and your total stake to see the combined odds, gross payout and gross profit if every selection wins.

Decimal odds for each selection
Combined odds—
Gross payout if every selection wins—
Gross profit before any deductions—

Leave unused rows empty. If one selection loses, the whole accumulator loses. Bookmakers may round combined odds slightly differently.

We never store what you type, and nothing is sent to bookmakers. With JavaScript switched on, the calculation happens entirely on your phone.

How it works

  1. Combined odds = the odds of every selection multiplied together.
  2. Gross payout = stake × combined odds.
  3. Gross profit = payout − stake.

The calculator keeps full precision while multiplying and only rounds the final money amounts to the nearest cent. Bookmakers sometimes round the combined odds first, so your bet slip may differ by a few cents.

Example

SelectionOdds
Manchester City to win1.40
Dynamos to win2.10
Over 2.5 goals, Chelsea vs Liverpool1.75

With a $1 stake: combined odds 1.40 × 2.10 × 1.75 = 5.145 (shown as 5.15), payout $5.15, profit $4.15.

Voids and draw-no-bet legs

If a match is postponed and voided, or a draw-no-bet leg ends level, that selection usually counts as odds of 1.00. Enter 1.00 (or remove the row) to see the new payout.

The catch: every selection must win

Each extra selection makes a win less likely. Five selections at 1.50 each give combined odds of 7.59, but by the bookmaker's own prices the chance of all five winning is only about 13%. Read accumulators explained and how bookmakers make money before building long slips.
