Three steps from raw cost numbers to a defensible, margin-positive pricing page. Each step is reactive — change one input and every downstream number updates live.
1Step 1
Define Your Costs
Start with the cost surface of your product. Calcaas separates fixed monthly overhead (servers, salaries, support) from variable per-unit costs (LLM tokens, image generations, audio minutes, video seconds). Pick from 1,500+ pre-loaded models — kept current with full capability data (context window, vision, reasoning, tool-calling) — or enter your own per-unit rate. Not sure which model? Tell Calcaas your requirements and it recommends the cheapest one that fits. Add transaction fees (Stripe, Lemon Squeezy, Paddle), VAT, and trial leakage so the numbers reflect what hits your bank account.

2Step 2
Build Your Packages
Stack as many tiers as you need. Pick a pricing mode per tier — target margin %, target profit $, fixed price, or credit-pack price — and Calcaas back-solves the other variables in real time. Toggle between monthly and yearly billing with discount controls, switch between 30+ currencies (Pro), and see live exchange rates pulled from the open currency-API. Side-by-side comparison shows where your tiers cannibalize each other vs. ladder cleanly.
Every input updates the dashboard live: gross margin %, profit per user, break-even user count, and MRR projections at three growth scenarios. The price-sensitivity simulator sweeps your price ±50% and surfaces the margin curve, so you can spot the price point where small drops cost real money. Export the model when you're done.

After per-unit costs, transaction fees, and VAT.
Profit per user / month
In your chosen currency, fully loaded.
Break-even user count
Users needed to cover fixed monthly overhead.
MRR projections
Three scenarios — conservative, base, aggressive.
Effective price per unit
What customers really pay per token / image / minute.
Price-sensitivity curve
How margin shifts when you move price ±50%.
Yearly-discount payback
Months until a yearly plan beats monthly.
Trial / free-tier drag
Real cost of every free user on the platform.
