Answer in brief
When you pass the volume included in an MMP plan, one of three things happens: you pay a per-unit rate for the extra, you are moved to a higher tier, or the vendor asks you to renegotiate. The plan page or the contract says which. Find the rule before you sign, because the month you pass the limit is usually a month when a campaign is working.
Three ways a plan handles extra volume
Every plan with an included volume has a rule for what comes after it. There are three common rules.
| Rule | How it works | What you see on the bill |
|---|---|---|
| Per-unit rate | Each unit above the included amount is charged at a stated price. | The base price plus a variable line. |
| Tier move | Passing the limit puts you in the next tier, for that month or from then on. | A step up to a new base price. |
| Renegotiation | The contract sets a ceiling. Above it, sales contacts you about new terms. | Nothing at first, then a new quote. |
The per-unit rate is the easiest to plan for because you can work out the bill yourself. The extra charge has a name, overage, and a good plan page prints its rate next to the included volume.
How to find the rule on a plan page
Look in three places, in this order.
- The line directly under the price. Phrases such as "then", "per additional" or "up to" mark the rule.
- The pricing FAQ, under a question about limits or what happens after a trial.
- The terms of service or order form, under usage or fees.
If none of the three states a rule, you do not know which one applies. Ask the vendor to put the rate in the order form.
A worked example with a per-unit rate
Airbridge Core includes 500K data points in the monthly price and then charges $0.0001 per data point.[1] Say an app records 800K data points in a month. That is 300K above the included amount. At $0.0001 each, the extra comes to $30 for that month, added to the plan price.
Two things follow from the arithmetic. First, the extra grows in a straight line, so a busy month costs more in proportion and nothing jumps. Second, what drives it is how many events you send, and you control part of that. The page on estimating a monthly bill shows how to turn your own user and event counts into a figure.
Limits that are not about volume
Volume is only one kind of limit. An entry plan can also cap the ad channels you may connect, the number of other tools you may send data to, the kinds of event you may record and the number of calls to an assistant or API. These limits have no overage rate. You either stay inside them or change plan. List them next to the volume limit so that a cheap month of overage does not hide a hard wall somewhere else.
What to do next
Before you sign, write one sentence for each plan you are comparing: "Above X units, the vendor does Y at price Z." If you cannot finish the sentence from the vendor's own pages, send it to them as a question.
After you start, check usage halfway through each billing period. One month above the included volume is normal during a launch. Three months in a row means the base plan no longer describes your app, and the guide on when to move up a plan covers how to decide.
Questions and answers
Does an MMP stop tracking when I hit my plan limit?
It depends on the vendor and the plan. Check the plan page or terms for the exact rule, and ask in writing if neither states it.
How do I avoid overage charges on an MMP plan?
Track only the events you use for decisions, review usage in the middle of each billing period, and compare a month of overage with the price of the next plan before you change anything.
