Quick Answer: Cost+margin pricing charges actual usage costs plus fixed margin, aligning vendor and customer incentives. Unlike token pricing, it rewards efficiency - when systems improve, customer costs drop and usage increases.
I built a pricing model where I only win when my customers win.
Why Token Pricing Creates Vendor-Customer Conflict
This creates a fundamental misalignment. Under token pricing, vendors make more money when their systems are inefficient. Under cost+margin pricing, vendors make more money when their systems get better.
The Token Pricing Problem
Traditional token pricing assumes 1,000 tokens always costs $0.002, regardless of type. But the reality is messy:
Input tokens cost $0.0015 per 1K. Output tokens cost $0.006 per 1K. Cached tokens cost $0.0007 per 1K. Cache writes cost $0.0030 per 1K.
So identical "1,000 token" conversations can cost vendors anywhere from $0.70 to $6.00—but customers pay the same flat rate.
This means token pricing vendors are incentivized to avoid caching (cheaper tokens = less revenue), increase output verbosity (longer responses = more tokens), skip optimization (inefficiency drives usage), and ignore retry reduction (failed attempts still count as tokens).
How Cost Plus Margin Pricing Works
How Cost+Margin Works
Instead of flat token rates, I calculate the actual cost of each conversation and add a fixed margin.
Real cost calculation: Input + output + cache costs down to fractions of cents. Fixed margin addition: Consistent 30% markup on actual costs. Transparent billing: Customers see exactly what they're paying for.
Here's a real example: 1,000-token conversation with 60% cached content.
Token pricing: Customer pays $2.00 (flat rate), actual cost is $1.20, vendor margin is 67%.
Cost+margin pricing: Actual cost is $1.20, margin is 30% ($0.36), customer pays $1.56. Customer saves 22%.
What Happened When I Switched Pricing Models
The Surprising Result
Lower costs should mean lower revenue, right? Wrong.
When customers see their bills drop due to optimization, they use more. My data over 6 months shows 38% increase in daily usage, 52% more experimental workflows, 24% higher feature adoption, and 67% longer retention.
The psychology shift is everything. Token pricing creates "usage anxiety"—every conversation costs money, better be careful. Cost+margin creates "usage confidence"—costs go down when the system gets better, I can explore more.
Lower per-unit margin times higher usage equals greater total profit.
Optimization Incentive Alignment
Under token pricing, vendors want to maximize token consumption, avoid efficiency improvements, increase response verbosity, and skip caching optimization. Result: customers pay more for worse service.
Under cost+margin pricing, vendors want to aggressively cache frequent requests, optimize response efficiency, reduce retry rates, and minimize unnecessary tokens. Result: customers pay less for better service.
When vendor success depends on customer efficiency, technology improves faster, customer satisfaction increases, usage grows naturally, and retention improves.
The Customer Response
Six months of data tells the story:
Before cost+margin: 23 conversations per user monthly, 34% feature exploration rate, 7.2/10 satisfaction, 8.3% monthly churn.
After cost+margin: 32 conversations per user monthly (+39%), 52% feature exploration rate (+53%), 8.7/10 satisfaction (+21%), 4.1% monthly churn (-51%).
Revenue impact: Per-conversation revenue down 18%, total conversations up 39%, net revenue per customer up 14%, customer lifetime value up 89% due to lower churn.
Implementation Reality
The main challenge is cost tracking complexity—real-time calculation across multiple API providers. I solved this with automated tracking using provider usage APIs and rate sheets, achieving 99.9% accuracy.
Customer education was easier than expected. Transparent billing breakdowns showing input/output/cache contributions actually increase trust compared to black-box token pricing.
The margin pressure from lower per-unit pricing requires higher volumes for growth, but usage acceleration through better customer experience more than compensates.
Industry Implications
As AI products mature, customers will demand cost transparency, usage optimization, aligned incentives, and predictable economics. Token pricing creates opacity and misaligned incentives—exactly what sophisticated customers will reject.
The competitive pressure is building. Companies still using token pricing will face demand for billing breakdowns, optimization improvements, transparency requirements, and value-aligned pricing.

The Philosophy Shift
Cost+margin pricing represents a shift from extraction to partnership, opacity to transparency, usage maximization to value optimization, and short-term margins to long-term relationships.
When vendor success depends on customer efficiency, everyone wins. Technology improves faster because optimization is profitable. Customer satisfaction increases because costs go down over time. Usage grows naturally because of lower anxiety barriers. Retention improves because interests align.
Common Objections
"Lower margins hurt profitability." Reality: Higher usage volumes more than compensate. Total profit increases through volume growth.
Cost Plus Margin vs Token Pricing Comparison
| Aspect | Token Pricing | Cost+Margin Pricing |
|---|---|---|
| Vendor Incentives | Maximize token usage | Optimize efficiency |
| Customer Psychology | Usage anxiety | Usage confidence |
| Technology Evolution | Slow (inefficiency pays) | Fast (optimization pays) |
| Customer Retention | Lower (misaligned value) | Higher (shared success) |
| Revenue Growth | Linear with usage | Exponential with satisfaction |

FAQ: AI Pricing Models
Q: What's the difference between token pricing and cost+margin? A: Token pricing charges flat rates regardless of actual costs. Cost+margin pricing charges real API costs plus fixed margin, aligning vendor and customer incentives.
Q: Why does cost+margin pricing increase usage? A: When customers see bills drop due to optimization, they use more. Lower costs create "usage confidence" instead of "usage anxiety."
Q: How much can cost+margin pricing save customers? A: In our example, customers saved 22% on identical conversations with 60% cached content - and usage increased 39%.
Q: Is cost+margin pricing more complex to implement? A: Yes, it requires real-time cost tracking, but modern API providers offer detailed analytics making this manageable.
The Bottom Line
Token pricing optimizes for vendor revenue. Cost+margin pricing optimizes for customer value.
When customers pay less per conversation, they engage more deeply with the product. When they engage more deeply, vendor revenue grows through volume rather than extraction. When revenue grows through value delivery, relationships last longer.
The companies that figure this out first will have significant advantages in customer acquisition, retention, and growth. The ones that stick with token pricing will compete on opacity while others compete on value.
The future of AI pricing is transparent, optimized, and aligned. The question is whether you'll lead this transition or be forced into it.
