With several prices on the same slip, it can be difficult to see how an accumulator's total was reached. Our free accumulator calculator lets you enter the individual odds and outcomes, then check the combined result. You can use it when browsing our online sports betting markets or when reading back an existing bet receipt.

Work from the slip you've confirmed when checking a settled wager. Its list of selections tells you how many rows to use, and Add Row extends the calculator if a leg is missing. Notes can identify the picks, which helps when you're comparing several similar prices.

The two boxes beside a fractional price hold its two numbers, in the same order as they're written on the slip. For 5/2, that's five followed by two. If you're working with decimal odds, change the format first so the entry matches the price you're copying.

The outcome setting needs the same attention. Leaving a row on Winner includes that pick as a winner in the calculation, even if it actually lost. Enter the results and stake from your receipt, then review the totals using those inputs. The calculator isn't reading your betting account or selecting the outcomes for you.

For the usual win-only calculation, decimal prices are multiplied together. You don't add them. When starting with a fractional price, dividing its first number by its second gives the ratio; adding one then gives the decimal price you need.

Start with the first two decimal prices. Their product gives the combined odds for a double. For a treble, the figure you've reached is multiplied by the third selection's decimal price. Each further leg extends the calculation in that same way, making a fourfold with four selections or a fivefold with five.

The return on a successful bet is that combined decimal figure multiplied by the stake. There's no additional stake to add afterwards: it's already included in the decimal calculation. Using a calculator saves that working-out, provided the entered prices and results belong to the correct bet.

A win-only accumulator has one stake on the combined outcome. It doesn't create separate singles, doubles and trebles in the way a full-cover bet does.

Several winning picks won't produce a partial win-only return if another leg loses. The figure for every selection winning belongs to that scenario alone. Reading it beside the result for a losing leg shows the difference between an assumed outcome and settlement.

The cost to compare with your spending limit is the full stake shown for the wager.

With each-way selected, you're following two sets of results through the same picks. The win side uses their win prices, while the place side needs the applicable place fractions entered as well.

A horse finishing in a paid place without winning needs a placed result. That can leave the place side successful while the win side loses, provided the other place legs also qualify. You aren't calculating separate place singles.

Entering a stake per part means that amount is committed twice, once to each half. Look at the two together when checking the outlay against your spending limit.

A withdrawn selection needs the outcome specified by your bet's rules. Where it's void, the remaining legs normally carry on without its price in the multiplication. For an ante-post withdrawal, read the market's rules first. Non-runner treatment can differ from a bet placed under non-runner-no-bet terms.

The Show Rule 4 option is for an applicable deduction. Enter the adjustment recorded for your bet and check any separate bonus conditions too.

Related Bet Builder selections need the quoted combined price. Multiplying their standalone odds won't account for the relationship between those outcomes.
