We build calculators that actually help you make decisions
AI Calcus is a free calculator platform focused on AI costs, creator earnings, SaaS metrics, and career planning. We started because the internet had too many vague estimates and not enough real math.
Our mission
To give every founder, creator, and professional instant access to the calculations they need — free, accurate, and without requiring a spreadsheet or an accountant.
We believe financial clarity shouldn't be locked behind paywalls or buried in complex models. A solo creator should be able to calculate their YouTube RPM as easily as a funded startup models its burn rate.
What we stand for
Real math, not estimates
Every formula is based on publicly documented pricing and industry-standard methodology. We show our work — inputs, formulas, and data sources are transparent.
Useful, not impressive
We design for the person who needs an answer in 30 seconds. No unnecessary complexity, no upsells, no locked results. Just the number you need.
Privacy first
All calculations happen in your browser. We don't store your inputs, don't require an account, and don't sell your data. Full details in our Privacy Policy.
Maintained & updated
AI pricing changes weekly. We monitor provider pricing pages and update affected calculators within 72 hours of published changes.
Calculation methodology
Every calculator on AI Calcus uses documented formulas with transparent data sources. Here's how we approach each category.
AI Cost Calculators
Pricing sourced directly from official provider API pricing pages (OpenAI, Anthropic, Google). Updated when providers publish pricing changes. Calculations use standard token math: (tokens / 1,000) × price-per-1K-tokens.
Creator Economy Calculators
CPM and RPM benchmarks sourced from industry reports (Influencer Marketing Hub, Creator Economy research) and cross-referenced with publicly available creator income data. Ranges reflect real variation across niches and geographies.
SaaS & Startup Metrics
Formulas follow industry-standard definitions from SaaS metrics authorities: David Skok (for SaaS Economics), OpenView Benchmarks, and Bessemer's State of the Cloud. LTV, CAC, and churn formulas match those used by leading VCs.
Career & Salary Calculators
Salary data sourced from Glassdoor, LinkedIn Salary, Levels.fyi, and Bureau of Labor Statistics. Cost-of-living indices from Numbeo and NerdWallet. Updated quarterly.
