What does this calculator do?
This calculator converts bankroll into unit or unit into bankroll according to the informed percentage. It organizes ranges and period exposure, without choosing bets, predicting results, or recommending values.

Bankroll Management Calculator for Football Betting
Calculate your betting unit, compare stake sizes, and explore how each scenario affects your bankroll over a series of bets.
Calculator
Compare unit scenarios
Enter the bankroll to calculate 1u or a unit to calculate the bankroll corresponding to the selected percentage.
Quick summary
| Point | Summary |
|---|---|
| Bankroll | Money set aside for betting, without mixing with everyday accounts. |
| Unit | Default value of 1u, calculated as a percentage of the bankroll. |
| Stake | Exposure assigned to a scenario: 0u, 0.5u, 1u, or 2u. |
| Ranges | Ranges A, B, C, and manual only change the percentage used in the simulation. |
| Common mistake | Varying the stake after a loss or without a fixed criterion. |
| How Predora helps | The calculator compares mathematical exposure; Predora organizes the analytical context. |
How to use the bankroll management calculator
- Enter your bankroll.
- Select a comparison range or enter the percentage.
- See your unit.
- Check daily exposure.
- Compare values on the same exposure scale.
Formula used
Unit = Bankroll × Percentage per betRequired bankroll = Unit ÷ Percentage per betDaily exposure = Unit × Number of betsExposure (%) = Daily exposure ÷ BankrollIn plain English: the informed percentage converts a slice of the bankroll into 1u. When there are multiple scenarios in the period, the calculator adds the units to show the total simulated exposure.
Example in football
In a simulation with a bankroll of $1,000 and Range B of 1%, the calculated unit is $10. In that scenario, 0.5u equals $5 and 2u equals $20.
Bankroll = $1,000 Percentage = 1% 1u = $10 0.5u = $5 2u = $20On the calculated scale, 1u equals $10, 0.5u equals $5, and 0u equals zero exposure. These equivalences do not change the probability, EV, or factors of a game.
How to interpret the result
| Unit | Practical reading |
|---|---|
| 0.5u | Exposure equivalent to half of the reference unit. |
| 1u | Exposure equivalent to one reference unit. |
| 2u | Exposure equivalent to twice the reference unit. |
| 0u | Zero exposure in the calculated scenario. |
Stake sizing shows how much each result affects your bankroll. Compare smaller and larger stakes while reviewing the probability, price, and match factors.

FAQ
What is bankroll management in betting?
Bankroll management is the method that relates bankroll, unit, and exposure per bet or period.
What is a betting unit?
A betting unit is a standard stake, usually calculated as a small percentage of the bankroll.
How does the percentage change exposure?
Higher percentages represent larger nominal values and potentially larger swings. The calculator compares these ranges without recommending a bet.
What happens when increasing the stake after a loss?
Exposure increases and the scale is no longer uniform; this does not change the probability nor mathematically recover the previous loss.
What does bankroll management help me measure?
Bankroll management shows how stake sizes affect exposure and results. Compare it with price analysis to evaluate both the bet and its size.
