AI & LLM Economics
LLM API costs, token estimates, GPU memory, adoption ROI, and research-based job exposure — the numbers behind building with AI.
Calculators
13 tools- aiLLM API Cost Calculator (GPT-4o, Claude, Gemini)Estimate monthly API costs for GPT-4o, Claude, and Gemini from tokens per request and volume. See input vs output cost split. Prices as of 2025 — verify.
- aiToken Counter & Context-Window Fit CalculatorEstimate the token count of any text with the chars/4 words/0.75 heuristic, check if it fits 8k, 128k, 200k, or 1M context windows, and gauge API cost.
- aiAI Build vs Buy Calculator (API vs Self-Host)Compare the monthly cost of a hosted LLM API against self-hosting on your own GPUs. Find the break-even token volume and see which option is cheaper for you.
- aiGPU VRAM Calculator (Model Size & GPU Fit)Calculate the VRAM a large language model needs by parameter count and precision (fp16, int8, int4), then see which GPU it fits — from RTX 4090 to H100.
- aiAI Tool ROI Calculator (Payback on Adoption)Estimate the ROI and payback of an AI tool: enter hours saved per week, staff count, and cost to see monthly net savings, break-even months, and annual return.
- aiAI Job Exposure ScoreAn AI job exposure score built from published research (Eloundou et al. 2023, O*NET, Goldman Sachs): estimate your task mix, not a prediction about you.
- aiAI Automation Payback Calculator (Process ROI)Estimate the payback of automating a process with AI: task volume, time saved, review effort, and API costs give net monthly savings and break-even months.
- aiLLM Self-Host vs API Cost CalculatorFind the monthly token volume where self-hosting an LLM on rented GPUs beats paying per token for an API. Compare costs, GPUs needed, and breakeven point.
- aiFine-Tuning Cost CalculatorEstimate what a fine-tuning run costs: GPU-hours for a self-managed cluster versus per-token managed API pricing, with wall-clock time and the cheaper path.
- aiRAG Cost CalculatorEstimate what a RAG pipeline costs: one-time corpus embedding, monthly vector storage, and per-query LLM generation from verified 2026 provider prices.
- aiAI Agent Cost CalculatorSee what an AI agent really costs per successful task: steps, tokens, model pricing and success rate turn dashboard cost per run into the true unit cost.
- aiPrompt Caching Savings Calculator (LLM API Costs)Estimate how much prompt caching cuts your LLM API bill: monthly input tokens, cacheable share, and hit rate give per-model savings, cache writes included.
- aiLLM Throughput & GPU Sizing CalculatorEstimate how many GPUs your LLM needs: concurrent users and target tokens per second become cluster size, monthly cloud cost, and real utilization at load.
