A pricing cliff is a point in a tiered pricing structure where a small increase in usage or spend triggers a disproportionately large jump in cost. In agency pricing, it means spending just over a threshold can suddenly add thousands to your monthly fee.
How do pricing cliffs work in agency fees?
Many agencies price campaign management in tiers: one fee for ad spend up to a threshold, and a higher fee beyond it. For example, an agency might charge one rate for spend up to 100,000 baht and a significantly higher rate above it.
Spend 99,000 baht and you pay the lower fee. Spend 101,000 baht and your fee jumps, even though your spend barely moved. The extra 2,000 baht of advertising can cost more in added fees than it delivers in results.
Why are pricing cliffs a problem?
They distort decisions. Budgets get set to stay under a tier rather than at the level that performs best, scaling a winning campaign gets penalised, and the agency's incentive to reach the next tier stops matching yours.
Cliffs also make costs hard to predict. If your spend moves with seasonality, your fees can swing sharply from month to month for reasons that have nothing to do with the work involved.
How can you avoid pricing cliffs?
Ask any agency for their full fee schedule and model your total cost at several spend levels, not just your starting budget. If the fee curve has sudden steps, you have found the cliffs.
Smooth models remove the jumps entirely. A fixed fee plus a small percentage of spend means every extra baht of budget carries the same small management cost, so decisions can be made on performance rather than fee thresholds.
This is how we price at Phoenix Media: a fixed monthly fee plus 7.5% of ad spend, so fees scale smoothly with your budget. You can see how it works on our service fee calculator.
