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 shows the arithmetic. It doesn't tell you whether the price fits your read of the outcome or your budget. Decide the stake before you enter it. Check the market rules. Keep essential money out of it entirely.

Cross-check on a second tool. The calculator hub, Poisson football score or Odds converter cover the same numbers from a different angle. Same price conventions, so a decimal price in one is a decimal price in the other.

Reading a rounded result

Money is rounded to two decimals here. A real settlement applies its own rounding sequence, which can differ. Keep the original inputs written down if you're going to check the number later.

Unclear about an input? Find the stated market term. Don't guess. A quick sanity check: change one input by a small amount and see whether the result moves the way you expect.

That doesn't validate the market. It can flag a reversed sign, a mis-entered price format or a duplicated stake. Use the number to understand the arithmetic. It's not a reason to ignore a limit you set in advance.
