Bankroll and staking calculator

Bankroll Flat or level stake Percentage stake % Number of bets Method Flat stake Percentage stake Level stakes

Example result

A 2% stake of 100.00 is 2.00; ten level losses draw down 20.00.

What this calculator answers

Compare a flat stake, a bankroll percentage and a level stake plan over a stated number of bets. The calculator shows the per-bet stake, total planned exposure and a simple losing-run drawdown.

Formula and worked example

Formula: Flat exposure = stake multiplied by number of bets. Percentage stake = bankroll multiplied by percentage. Drawdown after N losses = N multiplied by stake for a level stake.

With a 100.00 bankroll, 2 percent staking and ten bets, each stake is 2.00 and planned exposure is 20.00. Ten losing level stakes of 2.00 reduce the bankroll by 20.00.

Checks before using the result

• Counting the same bankroll more than once when using percentage stakes.
• Increasing a stake to recover a previous loss.
• Using money needed for rent, food, bills or debt payments.

When the calculation does not apply

It is a simple planning tool, not a forecast of outcomes. It does not model changing prices, deposits, withdrawals, charges or the emotional impact of losses.

Keep the number in context

A calculator makes the arithmetic visible, but it does not decide whether a price fits your budget or information. Write down the stake before placing anything, check the market rules, and keep essential money separate. The result is a planning figure, not a prediction of what will happen.

For another view, visit the calculator hub, compare the Poisson football score and Odds converter, or read the safer gambling self assessment. These tools use the same price conventions, so you can check a number from more than one angle.

Reading a rounded result

Displayed money amounts are rounded to two decimal places, while a real settlement can apply its own rounding sequence. Keep the original inputs beside the result if you need to repeat the calculation later.

If an input is unclear, pause and find the stated market term rather than guessing. A useful check is to change one input by a small amount and see whether the result moves in the direction you expect.

That does not validate the market, but it can reveal a reversed sign, an incorrect price format or a duplicated stake. Use the final figure as an aid to understanding the arithmetic, not as a reason to ignore a limit you set in advance.
