Rakeback and welcome bonuses reward different things. A welcome bonus adds a conditional balance once; rakeback usually accumulates from eligible play. Neither a large headline bonus nor a high reward percentage establishes which leaves you better off. A meaningful comparison uses the same planned stakes and counts only rewards you can actually convert.
Find the percentage's denominator
A percentage of theoretical house edge is not a percentage of stakes. In an illustrative programme paying 10% of theoretical loss, $1,000 of eligible stakes on a 4% house-edge game generates $4: $1,000 × 4% × 10%. It does not generate $100.
Other programmes use different formulas, game weights, VIP levels or discretionary components. Gamdom's official help states that its rewards are personalised and its exact formula is not public. Do not substitute a fixed industry formula for an operator that has not committed to it.
An illustrative 90-day comparison
Assume a person had already chosen a total entertainment turnover of $3,000 across 90 days, with a theoretical 4% house edge. Their expected gaming loss for that fixed turnover is $120 before rewards. At a hypothetical 10% rebate on theoretical loss, the reward would be $12 and the corresponding net theoretical cost $108.
A $100 welcome bonus with 35x bonus-only wagering demands $3,500 qualifying turnover. That exceeds the planned $3,000 before exclusions are considered. Its face value cannot be placed beside $12 as if both were withdrawable cash.

|---|---|---|---|---|
| Reward definition | 10% of theoretical loss | $100 restricted credit | ||
| Planned turnover | $3,000 | $3,000 | ||
| Calculated requirement | Eligible play generates $12 | $3,500 required to clear 35x | ||
| Unresolved terms | Claim deadline and cashability | Completion, cap, expiry and balance rules |
Why bonus EV needs more than RTP
For a fixed turnover, house edge gives an average gaming cost. A wagering promotion adds a stopping process: the balance may hit zero before completion, or expire, or finish above a cap. Correct expected cash-out depends on the distribution of those paths.
A model also needs to distinguish your original deposit from promotional money. Counting the whole ending balance as profit overstates value. Counting a advertised rakeback percentage as cash without its eligibility rules creates the same problem.
The extra-play trap
An additional $1,000 of stakes at a 4% edge has a $40 theoretical cost. A hypothetical 10% rebate on that cost returns $4, leaving $36 of expected loss. Increasing play to earn the rebate does not turn the added wagers into income.
The same logic applies to VIP targets and expiring bonuses. A reward that requires activity beyond your chosen budget changes the cost of the decision. Evaluate planned play first, then any reward that follows from it.
How to compare your actual terms
Record the eligible game, RTP or house edge, reward formula, claim timing, currency and withdrawal restrictions. For a welcome offer, add the wagering base, contribution and maximum cash-out. Keep cash and restricted credits in separate columns.
If the reward formula is undisclosed, label its future amount unknown. Historical account rewards can describe that account and period, but they should not be advertised as a universal payout rate.
Frequently asked questions
Is rakeback a refund of everything I lose?
Usually not. It may be based on theoretical loss, eligible stakes or a personalised formula rather than your actual session loss.
Which is better for a casual player?
It depends on the exact terms and planned play. An offer requiring more play than intended is not automatically valuable, regardless of its headline amount.
