Find the unit-economics problem hiding behind your AI feature
Model the expensive edge cases that average token calculators miss. Every tool uses current model pricing and produces an actionable answer—no signup required.
Tool 01 · Customer economics
AI SaaS Power User Calculator
Find the exact power-user mix your current pricing can survive.
Average usage hides margin risk. This calculator models normal and power users as separate economic cohorts.
CalculateTool 02 · Packaging and monetization
AI Credits Pricing Calculator
Price one AI credit and decide how many credits each plan should include.
This starts with real model COGS and works backward into a credit system customers can understand.
CalculateTool 03 · Plan guardrails
LLM Usage Limit Calculator
Set a usage allowance that is generous to customers and safe for gross margin.
The result is a customer-facing limit and overage price, not another abstract token-cost estimate.
CalculateTool 04 · Reliability economics
LLM Fallback Chain Cost Calculator
Measure reliability cost across primary calls, retries, fallbacks, and failed tasks.
A cheap request is irrelevant if several attempts are required to produce one accepted result.
CalculateTool 05 · Context economics
LLM Conversation Context Cost Calculator
Find the turn where conversation history becomes more expensive than the new message.
This models billed context turn by turn and compares full history with scheduled summarization.
CalculateTool 06 · Inference optimization
Prompt Caching Break-Even Calculator
Find the reuse rate and traffic volume required for caching to save money.
The result includes cache-write premiums and invalidation risk instead of assuming every repeated token is a hit.
CalculateTool 07 · Feature unit economics
AI Feature Profitability Calculator
Calculate contribution margin and the minimum profitable price for one AI feature.
It combines AI calls, human review, third-party tools, adoption, and incremental revenue in one feature P&L.
CalculateTool 08 · Vendor price risk
LLM Price Change Impact Calculator
Translate a model-price change into the exact action your SaaS business must take.
Instead of reporting new token prices, this calculates the required plan increase, usage reduction, or model switch.
CalculateWant to monitor the full business?
Use the complete margin simulator to combine plan revenue, model routing, infrastructure costs, and customer usage in one scenario.
LLM Margin's free tools focus on the business mechanics that determine whether an AI product scales profitably: uneven customer usage, credit redemption, retries, growing context, cache reuse, human review, and provider price risk. Results are estimates—validate them against your own production telemetry.
