The Matched Betting Trading exponential staking calculator shows how a percentage stake changes as your betting bank changes. Enter the bank you have already separated, choose 1% or 2%, and use the result as a boundary check before any live betting decision.
The bank figure must be money you are psychologically and practically prepared to lose. If losing it would affect rent, bills, food, debt payments, savings, or your ability to stay calm, the right next step is the Money Map, not a stake calculation.
Exponential staking sounds more dramatic than it needs to. In this tool it simply means percentage staking: the next stake is a fixed percentage of the current bank, so the stake automatically changes as the bank changes.
If the bank is GBP1,000, a 1% stake is GBP10. If the bank later becomes GBP800, the next 1% stake is GBP8. If it becomes GBP1,200, the next 1% stake is GBP12. The rule compounds with the bank rather than staying fixed.
Why this tool only allows 1% or 2%
The point is to make exposure visible, not to encourage larger bets. 1% and 2% are deliberately narrow settings because the psychological pressure of a losing run rises quickly when stake size is too large.
2% is not a small upgrade from 1%. It is double the amount at risk on every decision and produces a faster drawdown if several bets lose in a row.
Prepared to lose means prepared before emotion
The phrase prepared to lose should be taken literally. It does not mean you expect to lose or want to lose. It means the bank has been separated in advance and losing it would not change your essential spending, relationships, or decision-making.
That is why this page links to Money Map. If the bank has not been separated from bills and everyday money, the stake calculation is happening too late.
Where this fits with matched betting and qKelly
Percentage staking, qKelly, and matched betting calculators answer different questions. Treat them as separate checks, not competing promises.
Matched betting calculator
Use the matched betting calculator when the task is an offer workflow: qualifying stake, free-bet type, lay stake, liability, exchange commission, and both possible outcomes.
Use qKelly when you have a fair price or probability estimate and want to size a value-betting stake from edge. If the fair price is wrong, the qKelly output is wrong too.
Use this calculator when the first question is exposure: what is 1% or 2% of the bank, how does the stake change after losses, and would that stake still feel controlled?
Use Money Map before all of them if the bank is not clearly separate from essentials, savings, and everyday spending. It is a boundary tool before it is a betting tool.
