What this aviator calculator does
It gives the chance that a round reaches your cash-out target, the payout in rupees and the average cost of a session. It does not guess the next round; no tool can. The numbers come from the 97% return model that sets every Aviator crash point.

The aviator calculator formula
Aviator turns a 52-bit slice of a SHA-512 hash into a crash point with a formula that returns 97% of stakes over time. The chance that a round reaches multiplier x works out to:
P(reach x) = 0.97 ÷ x
Three results follow from it:
- 2x lands 48.5% of the time, not 50%. That 1.5-point gap is the house edge at 2x.
- About 4 rounds in 100 end at 1.00x, before anyone can cash out.
- Every target costs the same on average. Win chance × payout = 0.97 ÷ x × x = 0.97. You lose 3 rupees per 100 staked at 1.2x, at 2x and at 50x.
The aviator odds calculator above applies these numbers to your stake and the number of rounds you plan to play.
Aviator multiplier table: chance and streaks
Long losing runs are what end sessions; measure your own on the history page. This table adds the chance of 10 and 20 losses in a row at each aviator multiplier.
| Target | Chance per round | 10 losses in a row | 20 losses in a row | Average gap between wins |
|---|---|---|---|---|
| 1.30x | 74.6% | 0.0001% | ≈0% | 1.3 rounds |
| 1.50x | 64.7% | 0.003% | ≈0% | 1.5 rounds |
| 2.00x | 48.5% | 0.13% | 0.0002% | 2.1 rounds |
| 3.00x | 32.3% | 2.0% | 0.04% | 3.1 rounds |
| 5.00x | 19.4% | 11.6% | 1.3% | 5.2 rounds |
| 10.00x | 9.7% | 36.0% | 13.0% | 10.3 rounds |
| 20.00x | 4.85% | 60.8% | 37.0% | 20.6 rounds |
At 10x, a run of 20 straight losses happens in 13% of 20-round stretches. Plan a bankroll of at least 30 stakes for targets of 10x and above.
Aviator bankroll simulator
The odds calculator shows averages. The simulator shows the spread: it plays 2,000 sessions with your bankroll, stake, target and staking plan, drawing each crash point from the same model as the game.

Each round draws a crash point from the same model the game uses. Your browser runs the numbers; nothing leaves the page.
Run Martingale at 2x with LKR 5,000 and a LKR 100 base stake. Most sessions end a little up, and a slice ends near zero: five losses in a row cost LKR 3,100, and the sixth stake would be LKR 3,200 out of the LKR 1,900 left. Over all 2,000 sessions the average sits below zero by about 3% of turnover. Change the plan and the shape of the results changes; the average loss stays.
Three Sri Lankan budgets run through the numbers
LKR 2,000 after work
Stake LKR 50 at 1.5x auto cash-out for 40 rounds. You win about 26 rounds of LKR 25 profit and lose about 14 stakes of LKR 50. Turnover is LKR 2,000, so the average cost is LKR 60. A bad run of five losses costs LKR 250 and has a 0.5% chance per five-round stretch.
LKR 10,000 for the weekend
Two bets per round: LKR 150 at 2x and LKR 30 at 10x, for 150 rounds. Turnover reaches LKR 27,000 and the average cost LKR 810. The 10x bet lands about 15 times in 150 rounds, but gaps of 25 rounds without a hit are normal, so the small bet keeps the long shot affordable.
LKR 10,000 with the sports bonus
Aviator does not count toward the 1xBet casino bonus wagering, so a bonus chase on crash rounds goes nowhere. Mixed players use the sports track instead: a LKR 10,000 first deposit adds LKR 12,000 (120%), cleared by LKR 60,000 of accumulator slips within 30 days. The released cash can then go on Aviator with no wagering attached, sized with the calculator above.
Using the aviator prediction calculator at 1xBet
People search for an "aviator prediction calculator" hoping for a tool that names the next multiplier. What a calculator can do is fix your plan before the round:
- Pick a target. 1.5x for short, steady sessions; 3x–5x for fewer, bigger wins.
- Check the streak column. If 10 losses in a row would wipe out your budget, lower the stake.
- Set auto cash-out in 1xBet Aviator. Use the same number as in the calculator. Manual taps add delay.
- Stop at the session budget. Write it down before you start.

Aviator calculator FAQ
How does the aviator calculator work?
It uses the formula behind every Aviator round: the chance of reaching multiplier x is 0.97 ÷ x. From that it works out payouts, streaks and the average cost of a session.
Is this an aviator prediction calculator?
It predicts long-run results, not single rounds. No calculator can name the next crash point, because it depends on a hidden server seed.
What is the safest aviator multiplier?
Low targets such as 1.2x–1.5x win most often, but every target loses 3% of stakes on average. Low targets just make the losses smoother.
How many rounds end at 1.00x?
About 4 in 100 under the 97% model, before anyone can cash out.
Can I use the calculator for 1xBet Aviator in Sri Lanka?
Yes. Stakes are in LKR, and the maths is the same on every site that runs Spribe's Aviator.
