NGR is broadly GGR minus bonuses, payment costs, gaming taxes, and fees. The admin fee is the operator's catch-all line in that deduction stack, usually expressed as a flat percentage of GGR. Some operators itemize each cost; others roll everything into a single admin fee of anywhere from a few percent to well over 20 percent. The number lives in the terms and conditions, not in the pitch deck.
The arithmetic shows why it matters more than it looks. Take 10,000 of GGR, 2,000 in bonus costs, and a 40 percent RevShare. With a 10 percent admin fee, NGR is 10,000 minus 2,000 minus 1,000, which is 7,000, and your commission is 2,800. Raise the admin fee to 25 percent and NGR drops to 5,500, paying 2,200. Same traffic, same headline rate, 600 less.
This is the standard mechanism behind deals that look generous but pay thin. A 50 percent RevShare with a 30 percent admin fee and aggressive bonus deductions can pay out less per FTD than a 35 percent deal with a clean NGR definition. When comparing programs, the only honest comparison is effective commission per unit of GGR, not the advertised percentage.
Why it matters
The admin fee is where a RevShare deal is quietly repriced. Always ask for the full NGR formula in writing, check whether the fee is fixed or 'subject to change', and reconcile operator statements against your own tracked GGR when possible. A rate you cannot verify is a rate you cannot trust.
