AI Pricing Models: Subscription vs Credits vs Usage-Based Billing

AI products have unique pricing challenges: your costs scale directly with usage (every API call costs you money). The wrong pricing model can make your product unprofitable at scale. Here's how to choose.


The Three Models

1. Subscription with Usage Limits

How it works: Monthly fee includes a quota of generations/actions.

PlanPriceQuota
Free$010 generations/mo
Starter$19/mo100 generations/mo
Pro$49/mo500 generations/mo
Business$99/mo2,000 generations/mo

Pros: Predictable revenue, simple to understand, familiar to users. Cons: Hard to set limits (too low = frustrated users, too high = unprofitable). Best for: Tools with consistent per-generation cost (text generation, summarization).

2. Credit-Based

How it works: Users buy credit packs. Each action costs X credits.

PackPriceCredits
Starter$10100 credits
Growth$25300 credits (20% bonus)
Pro$50700 credits (40% bonus)

Pros: Users control their spending, no unused quota waste, flexible. Cons: Less predictable revenue, users may churn between purchases. Best for: Variable-cost actions (image generation costs more than text).

3. Usage-Based (Pay-Per-Use)

How it works: Charge per API call, per token, or per unit of work. Example: $0.01 per 1K tokens processed.

Pros: Fair pricing, scales with value delivered. Cons: Unpredictable bills for users, complex billing, harder to forecast revenue. Best for: Enterprise/API products, developer tools.


The Profitability Formula

For any pricing model, ensure:

Price per generation > Cost per generation x 3

If an AI generation costs you $0.02 in API fees, charge at least $0.06 (3x margin). This covers infrastructure, support, and business costs.


Implementation Recommendation

For MVP: Subscription with usage limits. It's the simplest to implement, easiest for users to understand, and provides predictable revenue.

After validation: Consider adding a credit-based option for power users or a pay-as-you-go tier.
