How it is calculated

With decimal odds, a winning bet pays back return = stake × odds, and that return includes your stake. The tool turns this around: stake = target return ÷ odds, profit = target return − stake and return on stake = profit ÷ stake × 100. Odds must be above 1 (decimal format such as 2.50, not fractions like 3/2 or American odds) and the target must be above zero; otherwise nothing is returned. Results are in dollars with two decimals, so read them in your own currency. The word guaranteed only means that this is the profit if the selection wins; the tool does not look at the probability of winning, commissions, taxes or what happens on a loss. Return on stake always equals (odds − 1) × 100.

Worked example

You want a total payout of 100 at decimal odds of 2.50. Stake = 100 ÷ 2.5 = $40.00. If the bet wins you receive 100, of which 40 is your own stake, so profit = 100 − 40 = $60.00. Return on stake = 60 ÷ 40 × 100 = 150.00%, which is the same as (2.5 − 1) × 100. If the bet loses, the 40 stake is lost, which the tool does not show.

Common mistakes

  • Entering fractional or American odds. The field needs decimal odds: 3/2 must be typed as 2.5 and +150 as 2.5 too; entering 3 or 150 gives a very different stake.
  • Treating the target as profit instead of total return. The target already includes the stake, so a target of 100 means a profit of 60 here, not 100.
  • Believing the profit is guaranteed in every outcome. It applies only if this bet wins; to lock a profit whatever happens, you need opposing bets on all outcomes, which this tool does not calculate.
  • Using odds of 1.00 or below. Odds must exceed 1, because at exactly 1 you only get your stake back and there is no profit.
  • Ignoring commission, taxes or limits. If the exchange takes a share of winnings, the real payout is lower than stake × odds.

About this calculator

The formula is a direct rearrangement of the payout equation: stake = target total return ÷ decimal odds. Since a decimal odds payout is stake × odds, solving for the stake that produces a specific total return tells you exactly how much to risk to lock in a chosen return figure, and the resulting profit (return − stake) and return-on-stake percentage fall straight out of the same numbers.

Sports bettors doing matched betting or arbitrage use this to size a back or lay stake precisely when covering multiple outcomes across bookmakers or an exchange, while bonus-hunters and value bettors use it to work out exactly how much they need to stake on a free bet or promotion to convert it into a guaranteed, fixed cash return.

    Try the same target return at two bookmakers' odds to see how much capital each needs. A target of 100 needs a stake of 40.00 at odds of 2.50, but only 38.46 at 2.60, so that extra 0.10 in odds frees about 1.54. The tool does not subtract commission, so on an exchange compare after your own deduction. Would stakes adjusted for commission or lay odds be useful to you?
