Step Percentage Staking Calculator — "Bookies Bank" (AUD)

A calmer percentage plan — the unit only re-steps after a ±10% bank move.

Loading calculator…

Step percentage — sometimes called a "Bookies Bank" plan — stakes a hundredth of your bank, but only changes the unit once the bank has moved a full 10% since it was last set. Between steps the stake is flat, so it’s far steadier than recomputing a percentage every bet.

Set the divisor and play a sequence: the unit holds until the bank crosses the next ±10% step.

How it works

By re-stepping only on a meaningful move, the plan captures the protection of percentage staking — stakes rise as you win and fall as you lose — without the jittery bet-to-bet changes. It’s a popular way to stake a fixed fraction of a growing bank smoothly.

Like all percentage-style plans it self-protects rather than chases, so it can’t bust to zero and can’t manufacture an edge. The 10% band just makes the ride calmer.

unit = ⌊bank ÷ N⌋ (N≈100), re-set only once the bank has moved ±10% since the last step.

Worked example

Bank $1,000 · divisor 100 · odds $3.00
  • Unit $10 (a hundredth of $1,000).
  • The unit holds until the bank reaches $1,100 or $900.
  • Cross that and it re-steps to a hundredth of the new bank.

Play a run above to watch the unit hold, then step.

FAQ

What is the Bookies Bank staking plan?
A stepped percentage plan: you stake a fixed fraction (about a hundredth) of your bank, but only update the unit after the bank has moved 10% — so the stake stays flat between steps.
Why only re-step on a 10% move?
It keeps the protection of percentage staking while avoiding a new stake on every single bet, giving a much smoother ride.
Is "Bookies Bank" the same as step percentage?
Yes — it’s the same stepped-percentage idea under a name punters often search for. The maths is identical.
