Why You Need to Know How to Calculate Bets[/b]
Make informed stakes: If you know how much you might win or lose, you can pick a stake (amount you bet) that matches your budget and risk tolerance.
Judge fairness: Betting sites often display odds and “automatic returns,” but if you understand how the calculation works, you can tell whether what they offer is reasonable.
Avoid surprises: Sometimes bettors assume they'll get more than they will, or don’t realize part of their world best football prediction site bet could be “half win” or “half loss.” Clear calculation helps avoid disappointment.
Before diving into formulae, here are a few terms:
Stake / Bet amount: the money you wager.
Odds: usually a multiplier provided by the bookmaker. If the odds are 2.0 and you stake 100, your return (if fully won) is 200, giving profit of 100.
“Full win,” “half win,” “half loss,” “lose fully”: These are possible outcomes depending on odds and conditions (especially in certain types of bets like handicap or Asian handicap, where part of your bet may be considered half won or half lost).
According to Keonhacaitructuyen, when you win a bet, the general formula is:
Amount Received=Stake × Odds
This applies when your bet is fully correct ("win full"). For example, if you stake 500,000 VND and the odds are 2.40, then:
Amount Received=500,000 × 2.40=1,200,000 VND
Profit (your gain)=Received amount – Stake=700,000 VND
Some bets don’t result in a full football prediction app download win but a half-win (thắng nửa tiền). That usually happens in handicap markets or in some over/under bets. The website gives this formula:
Amount Received=Stake × [(Odds + 1) / 2]
Using an example:
Stake=500,000 VND
Odds=2.40
Then (Odds + 1)/2=(2.40 + 1) / 2=3.40 / 2=1.70
So Amount Received=500,000 × 1.70=850,000 VND
Profit=850,000 – 500,000=350,000 VND
Calculating Losses[/b]
You also need to know how much you lose depending on outcomes:
Full loss (thua cả): If the bet loses completely, you lose your stake multiplied by the odds. Often:
Amount Lost=Stake × Odds
Example: Stake 500,000 VND, Odds 2.40 → Loss=500,000 × 2.40=1,200,000 VND
Half loss (thua nửa tiền): Again common in handicap / over-under / Asian handicap formats. The formula given is:
Amount Lost=(Stake / 2) × Odds
For example, same 500,000 VND stake, odds 2.40:
Half stake=250,000 VND
Loss=250,000 × 2.40=600,000 VND
Example Scenarios[/b]
Putting it all together, here are sample outcomes to illustrate fully:
Scenario A – Full Win[/b]
Bet Type: Standard
Stake: 500,000 VND
Odds: 2.40
Outcome: Full win
Receive=500,000 × 2.40=1,200,000 VND
Profit=1,200,000 – 500,000=700,000 VND
Stake: 500,000 VND
Odds: 2.40
Outcome: Half win
Received=500,000 × [(2.40 + 1) / 2]=500,000 × 1.70=850,000 VND
Profit=850,000 – 500,000=350,000 VND
Stake: 500,000 VND
Odds: 2.40
Outcome: Half loss
Loss=(500,000 / 2) × 2.40=250,000 × 2.40=600,000 VND
Money lost=600,000 VND

Stake: 500,000 VND
Odds: 2.40
Outcome: Loss
Loss=500,000 × 2.40=1,200,000 VND
While the above formulas apply to many “reliable bookmakers,” there are several things to pay attention to, because rules may vary:
Type of Bet Matters: Handicap bets, Asian handicaps, over/under, “draw no bet” etc. Each may have special rules (half wins, pushes, voids). Always check the specific market’s terms.
Odds Change Over Time: If you place the bet at one time and the bookmaker changes odds (before match starts or in live betting), that may affect what you get.
Timing: Some bets (especially live bets) have time windows where they apply. If you bet after a segment started, or after certain events, you might not get the full odds or may get adjust-ments.
Bookmaker Margins and Rounding: Sometimes odds are rounded or include margins (commission built in). The calculated amount may differ slightly due to rounding or how the bookmaker handles decimal placements.
Promotions, Bonuses, and Payout Policies: If you use a bonus stake or promotion, terms may include different payout percentages or “wagering requirements” that affect how much you can withdraw.
Better decision making: When you know potential return and risk, you can plan how much to stake in each bet.
Less “surprise” losses: Some bettors lose because they didn't foresee a “half loss” outcome or assume all losses will be just the stake.
Spot unfair offers: If a bookmaker’s automatic system gives you something that seems off (very low return or weird payout), you can recalculate and possibly detect mistakes or unfair terms.
To sum up:
Win full: Stake × Odds → get back your stake plus profit.
Half win: Stake × ((Odds + 1) / 2) → less profit than full win.
Full loss: Stake × Odds → lose full potential.
Half loss: (Stake / 2) × Odds → you lose half of what you would under a “full loss” rule.
