What is MoM
Month-over-Month is calculated as the value in the current month minus the value in the previous month, divided by the previous month value, expressed as a percentage. A GGR of 110 in May against 100 in April produces a +10% MoM. The metric is symmetric, so a fall from 100 to 90 produces minus 10% MoM, and the calculation can be applied to any operational KPI.
MoM is the working tempo of operator reporting. Monthly executive updates, trading reports, and KPI dashboards all anchor on it. The figure is sensitive to month-length differences and to seasonality, so it is typically presented alongside same-period YoY for context.
Common uses in iGaming reporting
Listed iGaming operators publish MoM movements in monthly trading updates, often called KPI updates or monthly trading statements. Revenue, active customers, deposits, and NGR are standard fields. Internally, MoM tracking covers more granular dimensions: vertical, jurisdiction, acquisition channel, and product segment.
MoM movements are also used to flag operational issues. A negative MoM in active customers that runs for two consecutive months typically triggers a retention review. A negative MoM in NGR alongside flat actives points to a problem on the cost side rather than acquisition.
Why MoM matters in B2B
For listed operators, MoM is one of the headline figures in investor reporting and a primary driver of equity narrative. For platform vendors, MoM tracking in customer success reviews informs renewal conversations and retention investment. For affiliates, MoM movements in operator GGR can trigger renegotiation of revenue share terms. Across the industry, MoM is the operational tempo at which performance is monitored and the standard window for tactical decisions, with weekly and daily numbers used as leading indicators and quarterly numbers used for strategic review.
Frequently asked questions about What Is Month-over-Month (MoM) in iGaming?
MoM compares the current month to the previous month. YoY compares the current month to the same month a year earlier. MoM captures short-cycle trends and seasonality; YoY smooths seasonality and captures structural growth. Operators report both.
Months have different lengths and different shapes. February has fewer days than March; some months contain more weekends or major event windows than others. Seasonal factors such as major sports tournaments or holiday periods also distort the comparison. Most reports note the comparable-period adjustments.
Like-for-like (LfL) MoM strips out the impact of newly launched markets, acquisitions, or divestitures. For underlying performance, LfL is the cleaner read. For total business momentum, raw MoM is the headline.
Usually as a single percentage figure for the headline metric, with supporting commentary on drivers and one-off items. Detailed trading statements break out MoM by vertical and jurisdiction with comparable-period context.
