No public formula exists.
Here's what actually is disclosed.
Every "weekly bonus calculator" you'll find online, this one included, is estimating — Stake confirms which factors go into the weekly and monthly bonuses but has not published the weighting. Below is what's actually confirmed, followed by a labeled floor estimate rather than a fake-precise number.
Two separate bonuses, on two separate clocks.
Both bonuses are described as factoring four inputs — VIP rank, wagered amount in the period, profit or loss over the same period, and the house edge of the games played — but Stake hasn't published how those four combine into a payout. Neither bonus carries a wagering requirement of its own once credited.
A minimum, not a prediction.
This estimator reuses the same disclosed shape as ordinary rakeback — wagered × house edge% × rate% — as a reasonable floor for what the period's bonus might be worth. Stake's actual weekly/monthly bonus can run higher, since it also weighs your VIP rank and recent profit/loss in a way this floor doesn't capture — a net-losing period is commonly reported as scoring a larger bonus than an identical wagered amount with a net win, all else equal.
Treat this as "at least roughly this much, quite possibly more" — not a number to expect exactly. It ignores the VIP-rank multiplier and profit/loss weighting Stake applies but hasn't disclosed the formula for.
Questions about a genuinely undisclosed formula.
Is there really no public formula for the weekly/monthly bonus?
Correct — Stake has confirmed the four inputs (VIP rank, wagered amount, profit/loss, house edge) but not how they're weighted into a dollar figure. Any calculator claiming an exact formula, including ones with impressive-looking math, is estimating just like this one.
Why would a net loss result in a bigger bonus than a net win?
This is a commonly reported pattern, not something we've independently confirmed with Stake's own documentation — it would be consistent with the bonus functioning partly as a loss-softening reward on top of ordinary rakeback, but we can't verify the exact mechanism.
Do I need to wager the weekly or monthly bonus before withdrawing it?
No — both are described as having no wagering requirement of their own once credited, unlike a typical deposit-match bonus.
What VIP level do I need to qualify?
Bronze is described as the minimum tier for both the weekly and monthly bonus — the same entry point as ordinary rakeback.
Does this floor estimate use the same formula as the VIP calculator?
Yes, deliberately — it reuses the same wagered × edge% × rate% shape as ordinary rakeback, since that's the only piece of this bonus with a disclosed formula. The real weekly/monthly figure layers undisclosed factors on top of that floor.
Why does the link expire after four weeks?
The weekly bonus link posted each Saturday is reported to remain valid for four weeks from when it's posted — after that it's no longer claimable, so it's worth checking the VIP Telegram promptly rather than letting it lapse.
Is there a best time to play to maximize this bonus?
Not one we can confirm. Since the exact weighting isn't public, any specific "optimal timing" claim is a guess dressed up as a strategy — the only genuinely disclosed lever is your own wagered volume in the period.
