Definition
In this glossary, loss-back means a promotion configured around a documented eligible-loss event, while cashback means a scheduled return calculated over a stated period. These labels are not universal standards. The exact trigger, timing, rate, cap, wagering, disclosure and eligibility must be defined for the promotion and approved under the applicable licence and player-protection rules.
Formula
Cashback = Cashback rate × Net losses over the period (with a cap)
Loss-back = Configured rate × Eligible loss under a documented event rule (with a cap)
Design parameters that must be set and tested for each licensed operation:
| Parameter | Cashback | Loss-back |
|---|---|---|
| Rate / size | Configured rate and cap by eligible segment | Configured rate, cap and event threshold; no universal range |
| Timing | Documented schedule | Documented delay after the approved event rule; no universal interval |
| Wagering | Licence- and promotion-specific; terms must be clear and within any applicable cap | |
| Trigger | Documented period close and eligibility | Documented event rule only after player-protection and licence review |
How operators use it
Loss-back can be tested as an event-triggered retention intervention, but neither speed nor offer size guarantees an uplift. Define eligibility, timing and loss calculation before launch, randomise an eligible holdout where lawful, and evaluate incremental LTV or NGR alongside responsible-gambling outcomes. A result from one cohort is not an industry benchmark.
Cashback plays a different role: it is a scheduled mechanic with a defined calculation window. Rate, cap, eligibility, wagering and disclosure are jurisdiction- and promotion-specific. In Great Britain, for example, the Gambling Commission's remote rules cap wagering requirements on bonus funds at ten times from 19 January 2026; the official guidance does not establish a global x1 standard.
Both instruments require governance as well as measurement. A significant or repeated loss can be a harm signal and should first trigger the operator's player-protection assessment, not an automatic promotion. Any offer must be lawful, clearly disclosed, limited to an eligible cohort and suppressed for self-excluded, restricted or at-risk players. Where a holdout is permitted, report incremental economics and safety outcomes; never design the mechanic as an inducement to chase losses.
Common misinterpretations
A common confusion is using "cashback" as an umbrella term for both mechanics, hiding different triggers, calculation windows and terms. The second error is economic: judging a program by redemption cost alone, without a control group, cannot separate incrementality from selection bias. The third is causal overreach: timing may be a treatment variable, but only a controlled comparison can show whether faster delivery changed the outcome.

Common questions
What is the difference between loss-back and cashback?
This glossary uses loss-back for a promotion configured around a documented eligible-loss event and cashback for a scheduled return calculated over a stated period. The terms are not universal standards; timing, rate, cap, eligibility, wagering and player-protection treatment must be defined for the exact promotion and jurisdiction.
What wagering requirement should apply to cashback and loss-back?
There is no universal multiplier. The promotion must comply with the relevant licence, advertising rules and published terms. For example, Great Britain's remote rules cap wagering requirements on bonus funds at ten times from 19 January 2026; that rule should not be extrapolated to another jurisdiction.
How much month-one retention can loss-back add?
There is no defensible universal uplift. Measure eligible players against a pre-registered holdout using the same cohort window, sample size, loss definition, player-protection exclusions and incremental NGR. Report uncertainty and adverse player-safety outcomes as well as retention.
