RevShare pays a percentage of net gaming revenue, and NGR can go negative. If a referred player wins big, or bonus costs and fees exceed what players lose, the operator's net result on your traffic is a loss for that month. Negative carryover determines what happens next: the deficit is carried forward and deducted from future earnings until the balance is positive again.
A worked example. Your players generate minus 3,000 NGR in January because one player hit a large win. In February the same cohort produces 2,000 of positive NGR. With negative carryover, February nets to minus 1,000 and you are paid nothing, and you still owe 1,000 against March. Without carryover, January is written off and a 40 percent RevShare on February's 2,000 pays you 800.
The clause appears in most operator RevShare agreements by default, sometimes softened with a cap, a time limit, or a reset after a number of consecutive negative months. The details matter as much as the headline commission rate: a 45 percent deal with unlimited carryover can pay less over a year than a 35 percent deal that resets monthly, especially with a small player base where one winner can sink the whole account.
Carryover risk also interacts with brand bundling. If an operator pools several of its brands into one account, a deficit on one brand can swallow positive earnings on another. Affiliates with concentrated traffic on high-variance products, live casino or sports betting in particular, feel this hardest.
Why it matters
Carryover terms decide whether a bad month costs you one payout or several. Before signing a RevShare deal, check whether carryover is capped, time-limited, or reset on request, and model your worst realistic month against it. Tracking NGR per brand and per period is the only way to know how deep a deficit actually runs.
