Usage-Based Pricing Calculator
Revenue from metered pricing — with the included allowance, overage rates and the gross margin at each usage level.
Usage pricing has three parts: a platform fee, an included allowance, and an overage rate.
How the usage-based pricing calculator works
Usage pricing has three parts: a platform fee, an included allowance, and an overage rate. Revenue is the fee plus whatever usage exceeds the allowance.
The margin question is the one that catches people. If the cost to serve scales with usage, a heavy user can be unprofitable at the overage rate while looking like the best customer on revenue. This shows the margin at the actual usage level, not the average.
Formula: revenue = platform fee + max(0, usage − included) × rate
Worked examples
| Inputs | Monthly revenue | Note |
|---|---|---|
| 24,000 units on a 10,000 allowance | 580 | 580 revenue, 75% margin |
| Inside the allowance | 300 | the platform fee only |
| A costly unit | 580 | the margin collapses |
FAQFrequently asked questions
Why use usage-based pricing?
Because revenue tracks the value delivered and expands without the customer adding headcount. It also lowers the barrier to starting.
What is the risk?
Unpredictable revenue and unpredictable bills. Customers dislike surprises, which is why most metered products include an allowance and alerting.
Why does cost to serve matter here?
Because it scales with usage. If the marginal cost approaches the overage rate, your heaviest users are your least profitable — the opposite of a seat model.
What margin should I target?
Software norms are 70 to 85% gross. Anything materially below that suggests the overage rate is too close to the cost.
Should I combine models?
Most mature products do — a platform fee for predictability plus metered usage for expansion. This calculator models exactly that shape.
