Stake Calculator
Choosing a stake for a slot is not done by guesswork. The calculator takes into account the bankroll, number of spins and acceptable drawdown. The recommendation is based on the slot’s mathematics and statistical data, rather than a random choice.
What Data the Calculator Uses
Two sources are used for the calculations. The first source is the official characteristics provided by the provider. The second source is SLOT STAT statistics, collected from gaming sessions.
Data from the provider
These are the characteristics stated by the game developer:
- RTP
- Volatility (Low / Medium / High)
They reflect the mathematical model of the slot and are used in the “Provider Model” mode.
Data from SLOT STAT
These are indicators calculated based on gaming session statistics:
- SRP (Statistical Return Percentage)
- Hit Rate
- Median Volatility
- Median Max Win
- Average Win
- Multiplier Distribution
They record the actual behavior of the slot over the selected observation period. This data is used in the “SLOT STAT Model” mode.
Why Results May Differ
Official characteristics describe the mathematical model of the slot. SLOT STAT data reflects the statistics of sessions that have already been played. Therefore, the same slot can simultaneously have an RTP of 96.50% from the provider and an SRP of 94.80% or 98.20% over a specific period. The stated volatility High does not always match the actual risk level in Median Volatility.
Because of this, the calculated stake, drawdown and other calculator indicators differ depending on the selected model.
The Provider Model shows how the slot behaves from the perspective of its stated mathematics. The SLOT STAT Model additionally looks at the actual session statistics and helps understand how the slot behaves in practice.
What Affects the Stake Size
The final recommendation is influenced by:
- bankroll;
- number of spins;
- acceptable drawdown;
- characteristics of the selected slot: RTP, SRP, Median Volatility, Hit Rate, Average Win, Median Max Win and multiplier distribution.
As a rule, a larger bankroll allows you to stake more. A longer gaming session usually requires a more cautious distribution of funds between spins.
It is important to consider that two slots with the same RTP may require a completely different approach to betting. High-volatility games are more likely to create deep drawdowns, and they need a larger bankroll buffer than low-volatility slots with the same RTP.
What the Game Styles Mean
The game style determines the level of risk in the calculations.
Careful Mode
lower risk, smaller bankroll fluctuations and usually a smaller recommended stake.
Moderate Mode
a balance between risk and stake size
Aggressive Mode
higher risk, larger bankroll fluctuations are allowed and usually a larger recommended stake.
How to Understand the Results
How Much to Stake on One Spin?
This figure is selected based on the session parameters and the chosen risk level.
Will You Be Able to Finish the Session in Profit?
The calculator estimates this probability statistically.
Calculated Drawdown
A conservative estimate of the possible decrease in bankroll under the given session parameters and slot characteristics.
All indicators are statistical estimates. They do not guarantee a specific gaming result.
Calculation Limitations
The calculations are based on a probabilistic model and historical statistics. Even with a large amount of data, the actual result of an individual session may differ significantly from the calculated values.
The calculator helps assess risk and choose a stake size. But it cannot predict the results of individual spins or bonus rounds, and it does not guarantee profit.
Why Use the Stake Calculator
Even slots with the same RTP can have significantly different levels of risk. The same stake can be comfortable for one slot and too high for another.
The SLOT STAT Stake Calculator selects the stake size taking into account the bankroll, risk and characteristics of a specific slot. No universal advice. The basis is the mathematical model of the game and statistics. This makes it possible to compare slots by risk level and find a suitable gaming format.
It does not predict the result of individual spins or increase the probability of winning. But it helps make decisions based on statistics and the mathematical model of the slot.
FAQ
What Is a Bankroll?
A bankroll is the money you allocate for a gaming session. The calculator uses this amount as the basis when calculating the recommended stake and assessing the risk.
What Is the Maximum Acceptable Drawdown?
Maximum acceptable drawdown means the part of your bankroll that you are willing to lose during a single gaming session. The higher the acceptable drawdown, the larger the stakes you can use, but the risk of losses also increases.
What Is Slot Volatility?
Volatility shows how much the results of the game can fluctuate. Low-volatility slots usually give frequent but smaller wins. High-volatility slots give wins less often, but potentially larger ones.
How Does SRP Differ from RTP?
RTP is the theoretical return percentage built into the mathematical model of the slot.
SRP (Statistical Return Percentage) shows the actual return of the slot over the selected observation period based on gaming sessions.
Over a short and medium-term period, SRP can be either higher or lower than RTP.
How Does the Provider Model Differ from the SLOT STAT Model?
The Provider Model uses the official slot characteristics published by the developer and does not take into account actual session statistics. The SLOT STAT Model additionally looks at data collected from a large number of gaming sessions: SRP, Median Volatility, Hit Rate, Average Win, Median Max Win and multiplier distribution. Because of this, the SLOT STAT Model sometimes recommends betting more cautiously, and sometimes more aggressively, based on the actual behavior of the slot.
Why Do Stakes Differ for Different Slots?
Two slots with the same RTP may have different volatility, payout structures and win distributions. Therefore, the safe stake size for them will be different.
How Does the Number of Spins Affect the Recommended Stake?
A longer session increases the influence of volatility and the risk of drawdown. The calculator may lower the recommended stake when the number of planned spins increases in order to preserve a bankroll buffer.
What Does the Probability of Finishing the Session in Profit Mean?
This is the statistical probability of completing the selected series of spins with a positive financial result. It is calculated based on the mathematical model used and the characteristics of the slot.
What Does the Calculated Drawdown Show?
A conservative estimate of the possible decrease in bankroll with the selected gaming session parameters.
Does the Calculator Guarantee Profit?
No. The calculator does not predict the results of individual spins or increase the probability of winning. Its purpose is to help choose a stake size and assess risk based on statistics and the mathematical model of the slot.
Which Slots Is the Calculator Suitable For?
The calculator works with slots for which data on RTP, volatility and other characteristics are available. The more statistics collected for the game, the more accurate the calculations in the SLOT STAT Model may be.
