Is Usage-Based Pricing Right for Your Business? | Metrifox

How to Assess Whether Usage-Based Pricing is Right for Your Business

Adedapo Sobayo•October 28, 2025

Software monetization is undergoing a massive shift. The traditional one-size-fits-all subscription model once the backbone of SaaS no longer reflects how customers expect to pay for technology. In a world where cloud platforms, APIs, and AI agents drive value in real time, businesses increasingly demand pricing that scales with measurable units, not arbitrary license counts.

This is where usage-based pricing comes in. Over the past five years, it has grown from a niche model to one of the fastest-rising trends in SaaS. OpenView's 2024 SaaS Benchmark Report shows that 61% of SaaS companies now offer usage-based pricing, more than double the adoption rate from 2018. On the demand side, enterprise buyers are just as clear: surveys reveal that over 65% prefer pay-as-you-go pricing because it lowers upfront risk, improves budget flexibility, and ensures they only pay for actual usage.

For AI-native and modern SaaS platforms, this alignment of revenue with customer success makes usage-based pricing not just an attractive option, it's becoming the default expectation.

What is Usage-Based Pricing (UBP)?

Definition

Usage-based pricing (UBP), also called consumption-based pricing, is a model that ties cost directly to a customer's actual usage of a product or service. Instead of paying a flat subscription, customers are billed for specific consumption events, such as API calls, compute cycles, storage capacity, or chatbot conversations.

The more they use, the more they pay; if usage drops, so does cost.

Customer Perspective

Perceive the model as transparent and fair, paying only for what they actually use.

Company Perspective

Benefit from a pricing system that scales automatically with adoption and customer success.

Why It's Growing Fast

This creates a powerful alignment between value delivered and revenue earned. It's why UBP has become the fastest-growing pricing strategy in SaaS and AI-native businesses.

If usage-based pricing feels familiar, that's because it is. Consumers already pay this way for electricity, mobile data, and cloud storage. In tech, it's now embedded across multiple layers of the stack:

Infrastructure Providers

Middleware & Developer Platforms

SaaS & AI Platforms

Where value is tied directly to queries, processing, or generated output.

But UBP Isn't for Everyone

The model also comes with challenges:

The Big Questions to Ask

Bottom line: UBP can be a growth engine if done right, but a risk if misaligned with your product's value drivers or customer expectations.

Frequently Used Usage-Based Pricing Models

To help you determine the right model for your business, here is a breakdown of common usage-based pricing (UBP) models, the key billing event for each, and examples.

Pay-as-you-go

Customers are billed per unit consumed (e.g., per API call or GB stored). Ideal for unpredictable demand, as it provides maximum flexibility.

When a user is billed: The customer is billed at the end of the billing cycle (e.g., monthly) for the total amount of usage they accumulated during that period.

Example: Amazon Web Services (AWS) offers pay-as-you-go pricing for its S3 cloud storage service. A customer is charged per gigabyte (GB) of data stored per month. A small startup using 100 GB in July would be billed for that amount at the end of the month. As their business grows and they use 500 GB in August, their bill for that month will increase accordingly, but they only pay for what they used.

Credit-based Pricing

Customers purchase credits in advance, which are then deducted as they use the service. This gives the customer greater control over their spending and helps the business with cash flow.

When a user is billed: The customer is billed upfront when they purchase a block of credits. They are then prompted to purchase more credits once their balance runs low.

Example: OpenAI uses a prepaid credit system for its API access. Developers purchase a certain amount of tokens upfront. As their applications make calls to the API for tasks like generating text or images, the cost is deducted from their token balance. Once the balance is depleted, the developer must purchase more tokens to continue using the service.

Overage Pricing

This model monetizes high-usage customers by charging for consumption beyond their plan's limits. It's a scalable way to align revenue with customer usage, without requiring upfront plan upgrades.

When a user is billed: The customer is billed a fixed subscription fee at the beginning of the billing period for a set amount of usage. At the end of the period, they are charged for any usage that exceeded that included amount.

Example: An AI-powered customer service platform might offer a Pro plan for $200 per month, which includes 500 chatbot conversations. If a company has a busy month and their chatbot handles 700 conversations, they are billed the $200 subscription fee plus an overage fee for the 200 conversations that exceeded their plan. The fixed fee is billed at the beginning of the month, and any overage charges are added at the end of the billing cycle.

Fixed Subscription with Usage Limits

Similar to overage pricing, this model includes a fixed fee but often provides more flexible usage tiers or credits that reset periodically, without overage charges.

When a user is billed: The customer is billed a recurring subscription fee at the start of the billing cycle. Their usage entitlements (e.g., a certain number of email sends) are renewed at the same time.

Example: A marketing automation tool like Mailchimp may offer a subscription tier that includes a certain number of emails sent per month. A user on a "Standard" plan gets 50,000 email sends each month. At the start of each month, the user's account is charged the monthly fee, and their 50,000 email sends are renewed. If they need to send more, they must upgrade to a higher subscription tier with a larger entitlement.

Hybrid Models

This model combines a seat-based or subscription fee for core access with a UBP component for specific, high-value features. It gives the company predictable revenue while capturing additional value from premium usage.

When a user is billed: The customer is billed a fixed, recurring fee (e.g., per user) at the beginning of the billing cycle. At the end of the cycle, they are also billed for any additional usage of premium priced features.

Example: A project management software like Jira could charge a fixed monthly fee per user for access to its core features. The company could then charge an additional fee for using a premium generative AI feature, such as a "report summary" tool, based on the number of times it is used. The customer's bill would include the fixed seat fees plus the variable fee for the AI usage at the end of the month.

Building Blocks of Usage-Based Billing System

To successfully implement a usage-based pricing (UBP) model, a business needs a robust system to manage several key components. This process is more intricate than a simple subscription model, requiring a specialized monetization and billing system.

Usage Events

Usage events are actions like file uploads, API calls, or messages sent. They're the foundation of billing: every invoice, metric, and report starts here. These events are timestamped, linked to a specific customer, and stored as raw or aggregated data.

Billable Metrics

Billable metrics are the specific units you track and charge for, derived from raw usage events. They translate customer activity into measurable activity, forming the basis of your pricing. Choosing the right metric is critical. It should reflect the value your customer receives and make pricing feel fair, transparent, and easy to understand.

Thresholds and Alerts

Thresholds are predefined limits on usage that trigger a specific action or notification. Setting up alerts in conjunction with thresholds helps prevent "bill shock" by giving customers transparency and control over their spending.

Custom Dimensions

Custom dimensions are additional pieces of information that you can attach to each usage event. These dimensions allow you to create more sophisticated and granular pricing rules based on different attributes of the usage.

How to Assess If UBP is Right for Your Business

To determine whether UBP is the right fit for your business, you need to move beyond a simple comparison of pricing models. Companies need to carefully weigh several variables to determine its suitability for their unique offerings, customer base, and business goals.

Does Your Product's Value Scale with Usage?

This is the most fundamental question to ask. For UBP to work, there needs to be a direct and obvious relationship between how much a customer uses your product and the value they receive.

Example: Stripe, a payment processing company, uses a UBP model. The value they provide (processing payments) is directly tied to the number of transactions a business handles. A small startup with only a few sales per month pays very little, while a large e-commerce company processing millions of transactions pays a proportional amount.

Can You Reliably and Accurately Meter Usage?

Before you can implement UBP, you must have the technical infrastructure to accurately measure every instance of usage in real time. This requires a robust metering system that can track and log specific actions without fail.

Example: Twilio, a communications platform, can accurately meter every single text message, phone call, or email sent through its API. This high level of metering accuracy is what makes their UBP model so successful.

What is Your Customer's Expected Usage Pattern?

Understanding your customer's usage habits is crucial. UBP works best when there is a wide variation in how customers use your product.

Example: Snowflake, a cloud data platform, caters to a wide range of customers, from individual developers to global corporations. Usage-based pricing is the ideal model for them because it eliminates the need for dozens of different subscription tiers.

What is Your Cost Structure?

UBP is often a great fit for businesses with variable costs. If your cost to serve a customer increases with their usage, a UBP model ensures that your revenue scales with these costs, protecting your profit margins.

Example: A generative AI company has a variable cost structure tied to the number of compute hours and GPU cycles required. UBP allows them to pass on these costs to the customer while the customer only pays for the output they receive.

Is Revenue Predictability a Priority?

One of the biggest trade-offs with UBP is the potential for unpredictable revenue. Since billing is tied to variable usage, your monthly revenue can fluctuate. If you need stable, predictable revenue for budgeting and forecasting, a pure UBP model might be too risky.

Example: For a new B2B SaaS startup with a small number of clients, a subscription-based model provides a predictable monthly revenue stream. A large, established company like Google Cloud, with a vast and diverse customer base, is better able to absorb the natural fluctuations of a UBP model.
