The bet calculator quickly works out the potential winnings and net profit for singles and accumulators. Enter the stake and the odds — the calculator will show the total payout, the profit and the accumulated odds of an accumulator.
Working out potential winnings is a basic skill for anyone betting on sports. The formula is simple: the stake is multiplied by the odds offered by the bookmaker. The result is the total payout, which includes both the stake itself and the net profit.
Single bet formula:
Winnings = Stake × Odds
Profit = Winnings − Stake
Example: a ₽1,000 bet at odds of 1.90 → winnings of ₽1,900, net profit of ₽900.
The odds offered by a bookmaker already include the margin — its commission. An example: Fonbet offers odds of 1.85 on a Zenit win. The fair odds (without margin) are 1.95. The difference: a ₽1,000 bet returns ₽1,850 instead of ₽1,950. On one bet the difference is ₽100; over a season (500 bets) it is ₽50,000.
Before placing a bet, check the margin in the margin calculator. If the margin is above 6%, look for odds at another bookmaker. Marathon and 1xStavka usually offer a margin of 2–4% on top events.
An accumulator (parlay) is a bet on several independent events at once. The total odds of an accumulator equal the product of the odds of all the selections. Winnings are paid only if every outcome is predicted correctly.
Accumulator formula:
Total odds = O₁ × O₂ × ... × Oₙ
Winnings = Stake × Total odds
Example: a ₽500 accumulator bet (1.50 × 2.10 × 1.80) = odds of 5.67 → winnings of ₽2,835.
Several nuances matter when calculating bets. The odds already include the bookmaker margin — the commission built into the line. The lower the margin, the better the odds for the player.
One rule applies to accumulators: if even one event loses, the entire stake is lost. So when building an accumulator, weigh up the combined risk. Advanced betting strategies suggest limiting the number of events in an accumulator to 3-4.
Most bookmakers have a built-in calculator in the bet slip: enter the stake and the potential winnings are shown automatically. However, a built-in calculator shows neither the margin, nor the fair odds, nor a comparison with other bookmakers.
Our calculator is useful for a preliminary check: enter the odds from the Fonbet, Winline or Liga Stavok lines — and compare the potential winnings before placing the bet. This is especially relevant for accumulators: the calculator shows the accumulated odds and the total winnings while you are still picking events.
| Bet type | Stake (₽) | Odds | Winnings (₽) | Profit (₽) |
|---|---|---|---|---|
| Single | 1 000 | 1.50 | 1 500 | 500 |
| Single | 2 000 | 2.10 | 4 200 | 2 200 |
| Accumulator (2) | 1 000 | 1.80 × 2.00 = 3.60 | 3 600 | 2 600 |
| Accumulator (3) | 500 | 1.50 × 1.80 × 2.20 = 5.94 | 2 970 | 2 470 |
The bet calculator is a bankroll planning tool. Before each bet it is worth working out the potential winnings and assessing how risky the bet is. For a systematic approach use the Kelly criterion, which determines the optimal stake size based on the probability and the odds.
It is also useful to understand ROI — the long-term return of your bets. A positive ROI means the strategy is profitable.
There are two main approaches to stake sizing. Flat staking — always the same amount (for example, ₽1,000). A simple approach: spending is easy to control, but it does not react to bankroll growth or decline.
Percentage of the bank (1–5% of the current balance) — an adaptive approach. A ₽50,000 bank with a 2% stake = ₽1,000. The bank grows to ₽60,000 — the stake is ₽1,200. The bank falls to ₽40,000 — the stake is ₽800. For an exact calculation of the optimal percentage use the Kelly criterion — it takes both the probability and the odds into account.
Before a bet, assess: your win rate over 200+ bets, the variance of results over short streaks, and the impact of the bookmaker margin. A bet on a favorite at odds of 1.30 requires a 77% win rate — one loss needs three wins to break even. A bet on an underdog at odds of 4.00 brings high profit on rare wins, but the variance is higher.
