Grand National each way bet calculator
Each way is the most popular way to bet on the Grand National, but it’s a bet that people who don’t bet regularly can occasionally miscalculate. An each-way bet is two bets of equal size: one on your horse winning, one on it finishing in the places. A £10 each-way bet costs £20.
Say you take £10 each way at 20/1, with place terms of a quarter the odds:
- Win part: £10 at 20/1 returns £210
- Place part: £10 at 5/1 (a quarter of 20/1) returns £60
- Total return: £270 from a £20 outlay, a profit of £250
If the horse places but doesn’t win, only the place part pays. You collect £60 from your £20 outlay, a profit of £40. Our each-way betting guide covers the strategy in more detail.
How to use our Grand National Each-Way Bet Calculator
- Switch Each Way on if you’re backing each way.
- Set the number of selections you’re betting on, which can be anything from one to 20.
- Pick the odds format you’re most familiar with. This could be fractions (eg, 7/1), decimals (eg, 8.0) or American (+700).
- Turn on Add Selection Notes if you want to label each row with a horse’s name rather than a number.
- Choose whether your stake figure is per bet or a total combined stake. This matters on multiples, so check it before reading the totals.
- Enter the stake.
- Fill in each row: the outcome, the win odds, the place odds and any Rule 4 deduction.
- Read off your outlay, return and profit. There’s no calculate button, the summary updates as you type.

Grand National accumulator calculator
An accumulator combines two or more selections into a single bet. Every leg has to win, and the odds multiply or accumulate, which is why returns get large quickly and why the sums are worth checking.
As an example, say you had four winners from a stake of £5, with odds of 2/1, 3/1, 5/2 and 4/1
In this case, the calculation would be 3.0 × 4.0 × 3.5 × 5.0 = 210, so £5 returns £1,050 for a profit of £1,045.
Doubles and trebles work the same way with fewer legs. Accas can also be placed each way, in which case you’re running two separate multiples, one on wins and one on places.
How to use our Grand National Accumulator Calculator
- Enter your stake.
- Set the number of selections. It defaults to four, but you can increase or decrease this number.
- Switch Each way on if required.
- Pick your odds format. It defaults to decimal but you can switch to Fractional or American format if you prefer.
- For each leg, enter the odds, the place fraction, the result and any Rule 4 deduction.
- If a leg dead-heated, fill in the tied position, the number of places paid and how many runners were involved.

Grand National place terms
Place terms decide the place half of an each-way bet, and they aren’t fixed. For a handicap the size of the Grand National, standard industry terms are a quarter the odds on four places. Most firms improve on that for Aintree, often paying five, six or seven places while dropping the fraction to a fifth of the odds.
That trade-off is worth understanding before you enter your numbers. On a 20/1 shot, a quarter the odds gives place odds of 5/1, while a fifth gives 4/1. More places means more chances of a return, but a smaller one when it lands. Some offers also apply only to selections above a certain price.
Terms are usually confirmed in the days before the race, so check your bookmaker’s terms and enter the actual place odds rather than assuming. Our each-way places page tracks who’s paying what.
Rule 4 deductions
If a horse is withdrawn late and there’s no time to form a new market, bookmakers apply a Rule 4 deduction to bets already struck at the old prices. Remove a runner and everything else in the race has become a little easier to back, so the deduction corrects for that after the fact.
Three things to know:
- It comes out of your winnings only. Your stake is always returned in full.
- It’s quoted in pence per pound of winnings. A 20p deduction takes 20% off your profit.
- The shorter the withdrawn horse’s price, the bigger the deduction. Long-priced non-runners often trigger none at all. Multiple withdrawals are cumulative.
Your bookmaker will announce the figure. Enter it in the Rule 4 column and the calculator will apply it.
Dead heats
If two or more horses can’t be separated for a place, your stake is divided by the number of horses involved and paid at full odds on that fraction. The remainder is treated as a loser. A £10 place bet in a two-way dead heat is settled as £5 at your place odds. The accumulator calculator handles this once you enter the tied position and the number of places paid.
Non-runners and free bets
Non-runners. If your horse doesn’t line up, a win single is void and your stake comes back. In a multiple, that leg is voided and the bet is recalculated on the remaining legs, so set the selection to Voided. Ante-post bets placed before non-runner-no-bet terms apply are a different matter, and the stake is usually lost. Check the terms you bet under.
Free bets. A free bet works like any other, with one exception: the stake isn’t returned with your winnings. A £10 free bet at 20/1 pays £200, not £210. Enter it as a normal stake and subtract the stake from the total return.
Converting odds formats
Decimal odds are just the fraction expressed as a total return per £1 staked, including your stake. So 20/1 becomes 21.0. Evens looks like this in each format:
- Fractional: 1/1
- Decimal: 2.00
- American: +100
All three describe an implied probability of 50%.
