Usage-Based Pricing
Charging in proportion to consumption rather than by fixed subscription.
What it changes in reporting
Recurring revenue becomes less predictable, and the definition of ARR requires care: only committed minimums are genuinely recurring. Treating variable usage as ARR overstates the run rate and every ratio built on it.
Expansion becomes automatic — and so does contraction
Growth in customer usage produces revenue growth without a sales motion, which is the appeal. The symmetry is that a customer's bad quarter becomes your bad quarter, immediately and without notice.
Forecasting is genuinely harder
How to operate it
Separate committed minimums from variable consumption in every report. Only the committed portion is genuinely recurring, and blending them makes ARR a forecast rather than a fact.
Build a consumption model, not a pipeline model, for the variable half. Applying opportunity-stage forecasting to usage revenue produces confident nonsense.
Instrument leading usage indicators per account so contraction is visible before it lands on an invoice.
Decide how to annualise a variable month and write it down. This single choice moves reported ARR materially.
Watch the concentration of consumption. A small number of heavy users frequently produce most of the variable revenue and most of the volatility.
Where it misleads
Expansion is automatic and so is contraction — the same mechanism that grows revenue when a customer grows shrinks it when they do not, with no sales event either way.
Usage-based NRR is partly a measure of your customers' business performance rather than your product's stickiness.
Revenue predictability falls, which affects planning and hiring more than the headline growth rate suggests.
A customer optimising their own consumption is behaving rationally and looks identical to a customer disengaging.
RELATED TERMS
Annual Recurring Revenue (ARR)
The annualised value of recurring subscription revenue at a point in time. A run rate, not a measure of revenue earned during a period.
Expansion Revenue
Additional recurring revenue from existing customers: more seats, higher tiers, additional products or increased usage.
Contraction MRR
Recurring revenue lost from customers who stayed but reduced spend — fewer seats, a lower tier, a renegotiated rate.
Freemium
A permanently free tier intended to build a user base from which some proportion converts to paid.
Forecast Accuracy
How closely forecasts match actual results, measured consistently over time. The metric that separates disciplined forecasting from lucky forecasting.
Net Revenue Retention (NRR)
Revenue retained from an existing cohort over a period including expansion, expressed as a percentage of where that cohort started. The clearest single indicator of whether the base grows without new customers.
COMMON QUESTIONS
- What is usage-based pricing?
- Charging in proportion to what the customer consumes rather than a fixed subscription — per API call, per unit processed, per seat actually active. Revenue then moves with the customer's own activity, which makes expansion automatic and contraction equally automatic.
- How does usage-based pricing affect ARR?
- It makes the definition require care. Only committed minimums are genuinely recurring; variable consumption is a forecast of recurring revenue rather than a fact. Reporting both blended as ARR overstates the reliability of the figure, so they should be separated in every report and the annualisation method written down.
- Is usage-based pricing harder to forecast?
- Materially, yes. Committed revenue forecasts like a subscription, but the variable half needs a consumption model built from usage trends and seasonality rather than from pipeline stages. Applying opportunity-based forecasting to consumption revenue produces a confident number with no method behind it.
- What is the main risk of usage-based pricing?
- Symmetry. The mechanism that grows revenue when a customer grows shrinks it when they contract, with no sales event and no warning in the pipeline. A downturn in your customers' business arrives directly in your revenue, and a customer optimising their consumption looks identical to one disengaging.
