Reference tables
Tables to look a number up instead of running a calculator. They come in two kinds, never mixed in one table: grids a calculator computes across a range of inputs, recomputed and checked on every build, and benchmark tables copied from a cited primary source, such as vendor pricing pages or the BLS, on a stated date. Each downloads as CSV and is free to cite.
Tables 9
- AI product gross margin by subscription price and token cost
Per-user gross margin for a one-person AI SaaS across every combination of monthly price and model output-token cost. Read off the margin floor before you pick a model.
8 subscription prices × 8 output-token prices, 64 figures. Source: AI Product Margin Calculator.
- LTV:CAC ratio by monthly ARPU and customer lifetime
Margin-adjusted LTV:CAC ratio for a subscription product across monthly ARPU and average customer lifetime, at a fixed $250 CAC and 80% margin. Find the 3× healthy floor before you scale acquisition.
7 ARPU tiers × 8 customer lifespans, 56 figures. Source: Customer Lifetime Value Calculator.
- CAC payback months by monthly ARPU and acquisition cost
CAC payback period in months across monthly ARPU and acquisition cost at 80% gross margin. See exactly where payback crosses the 12-month healthy line before funding growth from cash flow.
7 ARPU tiers × 8 acquisition-cost levels, 56 figures. Source: CAC Payback Calculator.
- AI support savings by ticket volume and deflection rate
Monthly cost savings of an AI-first support desk versus humans across ticket volume and AI deflection rate. See where weak deflection actually costs more than staffing agents.
6 ticket volumes × 7 deflection rates, 42 figures. Source: AI vs Human Support Cost.
- Embeddings DB cost by stored vectors and query volume
Cheapest hosted vector-database monthly cost across stored vectors and daily queries, over Pinecone, pgvector on Supabase and Turbopuffer, with LanceDB on R2 alongside.
6 vector counts × 7 query volumes, 42 figures. Source: Embeddings DB Cost.
- LLM switching payback by monthly spend and new-vendor discount
Months for a cheaper model vendor to repay the migration cost, across current monthly spend and the discount offered. See where lock-in is real and where it pays to switch.
6 spend levels × 7 vendor discounts, 42 figures. Source: LLM Vendor Lock-In Cost.
- SaaS viability grid: LTV:CAC ratio and CAC payback by price and churn
LTV:CAC ratio and CAC payback months across monthly price ($20–$500) and monthly churn rate (1%–8%), at $500 CAC and 75% gross margin. Shows which pricing and retention combinations are viable before you scale acquisition.
5 price tiers × 5 churn rates, 25 figures. Source: Unit Economics Calculator.
- 2026 AI vendor pricing and TCO report
Public pricing across LLM APIs, vector databases, AI support agents, and LLM observability, each rate read from the vendor's own page and dated on its row (the LLM rows from the shared model catalog), plus two engine-computed total-cost-of-ownership scenarios. Downloadable CSV.
4 categories, 32 rates, 32 figures. Source: AI Stack Cost + Embeddings DB Cost.
- Freelance rates by role: the 2026 BLS-verified US table
Hourly P25/median/P75 wages for 15 freelance roles from BLS OEWS May 2025 — every figure verified against the BLS Public Data API on 2026-07-12 — plus a freelance-equivalent floor derived with a fully disclosed ECEC multiplier. Downloadable CSV.
15 roles × 3 wage percentiles, 45 figures. Source: BLS OEWS + Freelance Rate + Capacity Planner.
Every table states its inputs and sources, and the build fails if a computed cell no longer matches its calculator. To run your own numbers, open the calculators; each shows its formula, assumptions and sources.
